18 Performance Review Examples for Software Engineers (by Level)
By Samira Bahmanyar · HR Manager
You're in the right place if you're an engineering manager writing a review about one of your engineers. If you're the engineer writing your own self-review, head to self-review examples for software engineers instead — the angle, the voice, and the artifacts you cite are different.
Vague praise is the silent killer of engineering reviews. "Strong ownership," "great team player," "shows technical depth" — calibration committees can't defend them, engineers can't grow from them, and HR can't tie them to compensation. The fix isn't more adjectives. It's a citation.
Every example below follows one reusable formula:
[specific claim] + [artifact citation: PR, ticket, dashboard, incident, doc] + [measurable impact]
That's it. Eighteen examples, organized first by level (Junior → Staff), then re-cut by competency (delivery, code quality, collaboration, leadership) so you can find the angle you need fast. Each one has a strengths variant and a development-area variant.
Key Takeaways
- Specific reviews change behavior; generic reviews don't. Use the [claim] + [artifact] + [impact] formula on every bullet.
- Calibrate by level — "good ownership" looks completely different for a junior vs. a staff engineer (Radford 2026 leveling data).
- Pair every strength with a development area at the same level of specificity; one-sided reviews fail at calibration.
- Swap nine common vague phrases for the evidence-backed rewrites in the table below.
- If you're an engineer writing your own review, this post is the wrong post — use self-review examples for software engineers.
What makes a software engineer review example actually usable?
A usable example is one a manager can paste, swap two artifact IDs, and ship to HR. According to Gallup's 2026 State of the Global Workplace, only 14% of employees say their reviews inspired them to improve — and the top complaint is that comments are too vague to act on. Specificity is the fix.
Three traits separate a usable example from filler:
- It names an artifact. A PR number, a Jira ticket, an incident ID, a dashboard, a design doc, a Slack thread. Without an artifact, "led the migration" is unverifiable.
- It quantifies impact. Latency cut from 480ms to 290ms. Test coverage from 41% to 78%. INC-204 mean time to resolution under 22 minutes.
- It maps to the level's rubric. "Mentored juniors" is a Senior expectation, not a Mid one. Praising a Mid for it inflates the review.
Anything missing one of those three is a candidate for the rewrite table at the end of this post.
Performance review examples for software engineers — by level
The 18 examples below are organized Junior → Staff. Each level gets four to five examples split between strengths and development areas. Generic placeholders ("authentication service," "checkout pipeline") replace any company-specific names — drop in your own systems before sending.
Junior engineer (IC1 / SDE I) performance review examples
Junior engineers are evaluated on scoped delivery, learning velocity, and responsiveness to feedback — not on architecture or cross-team influence.
1. Strength — Delivery (Junior)
"Closed 23 tickets in Q1 against a target of 18, including the authentication service input-validation hardening (PR #482, PR #491) that retired three CVE warnings from our Snyk dashboard. Velocity has been consistent across three sprints — no rollovers."
2. Strength — Learning velocity (Junior)
"Owned their onboarding plan end-to-end. Went from first PR-merged in week 3 to independently shipping the rate-limiter refactor (PR #538) by week 11, a faster ramp than the team's six-month median. Asked clarifying questions in design reviews instead of staying silent — a marked shift from January."
3. Development area — Code review responsiveness (Junior)
"Pull-request turnaround averaged 3.4 days against a team norm of 1.5 (GitHub Insights, Jan–Mar). Several reviews (PR #501, PR #517) stalled because reviewer comments weren't addressed in the same working day. Goal for Q2: respond to review comments within 24 business hours or post a blocker note in the PR."
4. Development area — Test coverage (Junior)
"Three of their last six PRs (#544, #552, #560) shipped with no new unit tests, requiring follow-up tickets (JIRA-1124, JIRA-1131). Coverage on the checkout-pipeline module they own dropped from 74% to 68%. Q2 goal: tests included in the same PR as the change, no exceptions."
Mid-level engineer (IC2 / SDE II) performance review examples
Mid-level engineers are evaluated on independent delivery of medium-sized features, design judgment within a service, and reliable peer code review.
5. Strength — Technical delivery (Mid)
"Led the auth-service token-rotation rework end-to-end (RFC-72, PR #482, PR #495). Cut p95 auth latency 38% (480ms → 297ms on the auth-latency Grafana dashboard) and resolved INC-204 within 22 minutes of paging. Delivered the project two days ahead of the RFC timeline."
6. Strength — Code quality (Mid)
"Sustained one of the highest review-comment-acceptance rates on the team — 89% of their review comments resulted in author changes (LinearB, Q1). Their feedback on PR #612 caught the N+1 query that would have hit us at peak. Two engineers cited their reviews as the most useful in the team retro."
7. Strength — Reliability (Mid)
"On-call shifts in February and April closed with zero unresolved tickets at handoff and a clean runbook diff (wiki/runbooks/auth-service). Wrote three new playbooks during the rotation, two of which a junior used solo the following week."
8. Development area — Scope estimation (Mid)
"Three of their last four projects (RFC-58, RFC-66, RFC-71) shipped 25–60% over the estimated timeline. Root cause across all three was under-scoping the integration test work. Q3 goal: every RFC includes an explicit testing section with day-level estimates before approval."
9. Development area — Written communication (Mid)
"Strong verbal contributor in syncs, but design docs (e.g. RFC-66) skip the Alternatives Considered section and rely on the reader having context from earlier conversations. Two reviewers asked the same clarifying question on the last three docs. Q3 goal: every RFC ships with a complete alternatives section and a TL;DR."
Senior engineer (IC3 / SDE III) performance review examples
Senior engineers are evaluated on cross-team technical leadership, mentorship, and ownership of an entire service or workflow.
10. Strength — Technical leadership (Senior)
"Drove the checkout-pipeline reliability initiative across three teams (RFC-81, project tracker). Reduced checkout error rate from 1.8% to 0.4% (Datadog, Mar–May) and led the post-mortem for INC-301 that exposed our retry-storm anti-pattern. The pattern doc they wrote is now linked from the platform onboarding guide."
11. Strength — Mentorship (Senior)
"Mentored two engineers through promotion packets this cycle. Their mentee's PR #538 (rate-limiter refactor) was cited in calibration as the strongest IC1→IC2 promotion artifact this half. Holds a weekly 30-minute office hour that 4 of 7 team members attend."
12. Strength — Code quality at scale (Senior)
"Authored the team's API-versioning conventions (docs/api-versioning.md) after the v2 rollout incident. The guide has been referenced in 14 PRs across two teams this quarter. PR review feedback consistently rated 'most useful' in anonymous team retros."
13. Development area — Delegation (Senior)
"Took on two of the four critical-path tickets in the checkout-pipeline project personally (JIRA-2204, JIRA-2218) when both could have stretched a Mid engineer on the team. Result: faster ship, but a missed growth opportunity called out by the Mid in their 1:1. Q3 goal: identify one stretch ticket per sprint for a teammate before picking it up."
14. Development area — Strategic visibility (Senior)
"Technical execution is consistently above bar, but the broader org doesn't see it. No tech-talk, no engineering-blog post, and no cross-org RFC review participation this half. Q3 goal: one of those three (talk, post, or sustained cross-org RFC engagement) by end of cycle."
Staff / Principal engineer (IC4+) performance review examples
Staff engineers are evaluated on org-level impact, multi-quarter technical strategy, and force-multiplication through others.
15. Strength — Org-level impact (Staff)
"Authored the platform-consolidation strategy (strategy doc, exec readout deck) that retired two redundant internal services and freed roughly 1.4 engineer-equivalents in maintenance load (capacity planning, Q1). Strategy was adopted by both Platform and Payments leadership and is now the reference for the FY27 roadmap."
16. Strength — Force multiplication (Staff)
"Their authored review templates and RFC checklist (engineering wiki) are now used by every team in the org. Three managers cited measurable improvements in design-doc quality in their team retros. They themselves wrote fewer lines of code this quarter than last — by design — and the org shipped more."
17. Development area — Decision velocity (Staff)
"Two architectural decisions (RFC-77 data-store choice, RFC-83 eventing layer) stayed in 'gathering input' for 6+ weeks each, blocking dependent teams. Feedback in the cross-team retro flagged 'analysis without a decision date.' H2 goal: every RFC they own has an explicit decision-by date in the doc header."
18. Development area — Building successors (Staff)
"Continues to be the primary on-call for two of our highest-severity systems (auth, payments). PagerDuty data shows them paged on 71% of P1s in those systems this half. Q3 goal: a documented succession plan for at least one of the two systems, with a named Senior engineer running their next on-call rotation as primary."
The reusable formula every example above uses
Reread the 18 examples and you'll see the same shape every time:
[claim] + [artifact citation] + [impact]
- Claim: what they did. ("Led the auth-service token-rotation rework.")
- Artifact: how you know. (RFC-72, PR #482, INC-204)
- Impact: what changed because of it. ("p95 auth latency 480ms → 297ms.")
If any of your bullets is missing one of those three, it's a candidate for the next section.
Performance review examples organized by competency
Same 18 examples, re-sliced for the manager who's thinking "I need a code-quality bullet for Priya" instead of "What does a Senior strength look like?"
| Competency | Junior | Mid | Senior | Staff | |---|---|---|---|---| | Technical delivery | #1, #2 | #5, #7 | #10 | #15 | | Code quality | #4 | #6 | #12 | — | | Collaboration / communication | #3 | #9 | #11 | #16 | | Technical leadership | — | #8 | #10, #13, #14 | #15, #17, #18 |
A clean review usually pulls one bullet from each row that's lit up for the engineer's level — typically two strengths and one development area for a healthy distribution.
Phrases to avoid (and the evidence-backed rewrite)
The left column is what calibration committees see and roll their eyes at. The right column is the same intent, rewritten with the [claim] + [artifact] + [impact] formula.
| Vague phrase to avoid | Evidence-backed rewrite | |---|---| | "Strong ownership" | "Owned the auth-service migration end-to-end — RFC, implementation, runbook, on-call handoff (RFC-72, PR #482, runbook diff)." | | "Great team player" | "Reviewed 41 PRs this quarter (top 3 on the team, LinearB Q1), and two engineers named their feedback as most useful in the team retro." | | "Shows technical depth" | "Diagnosed the INC-204 retry storm in under 22 minutes and wrote the pattern doc the platform team now references (docs/anti-patterns/retry-storm.md)." | | "Good communicator" | "RFC-72 was approved with zero major-rev requests across 4 reviewers — a team-leading record for the half." | | "Needs to step up" | "Pull-request turnaround averaged 3.4 days against a team norm of 1.5 (GitHub Insights). Q2 goal: 24-business-hour response on review comments." | | "Could improve code quality" | "Three of their last six PRs (#544, #552, #560) shipped with no new unit tests; coverage on the checkout module dropped 74% → 68%." | | "A real go-getter" | "Self-selected onto the platform-consolidation initiative and authored the strategy doc that's now the FY27 roadmap reference." | | "Reliable under pressure" | "Closed February and April on-call shifts with zero unresolved tickets at handoff and three new runbooks in wiki/runbooks/auth-service." | | "Inconsistent performer" | "Sprints 1, 3, and 5 finished green; sprints 2 and 4 carried 40%+ rollover. Common factor across the rollover sprints: under-scoped integration testing." |
If you can't yet name the artifact in the right-hand column, that's not a writing problem — it's a data-collection problem, which is the actual root cause of most weak reviews.
From 18 examples to a full review
These examples are the bullets, not the whole document. To assemble them into a complete review — overall summary, calibration narrative, growth plan, compensation rationale — work through our walk-through on how to write a performance review for engineers. And for the cycle-level pitfall that quietly biases most of these bullets toward the last six weeks, see our piece on recency bias in performance reviews.
Engineer reading this for your own self-review? Wrong document. The framing is opposite — you're claiming the work, not characterizing someone else's. The companion piece is self-review examples for software engineers.
Where PerfCopilot fits
The hard part of writing reviews like the 18 above isn't the phrasing — it's reconstructing six months of artifacts. PRs merged in week 2. The incident from sprint 4 nobody documented. The Slack thread where Priya unblocked the payments team.
PerfCopilot pulls that history directly from GitHub, Jira, and Slack and assembles citation-ready review drafts in the exact [claim] + [artifact] + [impact] shape used throughout this post — with recency-bias and tone checks baked in. Free for up to 5 reviews, Pro at $4.99 per user per month billed annually. The point isn't that PerfCopilot writes the review for you. It's that the artifacts stop being the bottleneck.

Frequently asked questions
How many examples should a software engineer's review include?
Aim for 6–9 bullets total: 2–3 strengths, 2–3 development areas, and 1–2 forward-looking goals. Each bullet should use the [claim] + [artifact] + [impact] pattern. Reviews longer than 12 bullets dilute calibration signal and become impossible for HR or comp committees to weight — Lattice's 2025 manager benchmark data points to 7 as the median for high-quality cycles.
What's the difference between a Junior and a Senior performance review example?
The scope of the artifact and the expected level of impact. A Junior strength bullet cites a single PR that closed a contained ticket. A Senior strength bullet cites an RFC plus a multi-PR initiative plus a measurable team or service-level outcome. Praising a Junior in Senior language inflates calibration; reviewing a Senior in Junior language under-levels them. Anchor every bullet to the engineer's current rubric, not the next one.
Can I just reuse these examples for self-reviews?
No — and that's not because they're locked, it's because the frame is wrong. A manager review characterizes the engineer's work from the outside ("Drove the checkout reliability initiative"). A self-review claims the work from the inside ("I drove the checkout reliability initiative, and here's the evidence"). Different voice, different audience, different selection bias to watch for. Use self-review examples for software engineers.
What if I don't have artifacts (PRs, tickets, dashboards) for an engineer?
You have a data-collection gap, not a writing gap, and it's the most common root cause of vague reviews. Three quick fixes: (1) ask the engineer for their brag doc before you draft, (2) pull a six-month diff of their GitHub and Jira activity yourself, or (3) use a tool that aggregates this automatically. Reviews built without artifacts collapse in calibration — they read as opinion, not evidence.
Should I include growth areas for a top performer?
Yes. A review that's pure strengths reads as either a calibration error or as the manager not paying close enough attention. Even staff-level engineers have development areas — see examples #17 (decision velocity) and #18 (building successors). High performers expect specific, calibrated growth feedback; its absence is one of the top three predictors of regret-attrition in the 2026 Culture Amp engineering benchmark.
TL;DR
Every line of a software engineer's review should follow [claim] + [artifact] + [impact]. Calibrate the artifact and impact to the engineer's level. Pair strengths with development areas of equal specificity. Swap the nine vague phrases above for the rewrites. And if you're the engineer, not the manager, you want self-review examples for software engineers instead.
