Performance review template for a software engineer
A ready-to-use, section-by-section template with the competencies that matter for a software engineer, role-specific example phrases, and a guard against the stock filler that makes most reviews read as generic. Copy the structure, fill in your evidence, or skip the writing entirely with Crestento.
The template
Four sections, in this order. Length should match the evidence you have — a thin section is honest; an invented paragraph is not.
Summary
One or two paragraphs setting the context: what was expected of software engineer — senior this period, and your overall verdict. Lead with the headline.
Example phrasing
“Led the platform-tier rewrite end-to-end across three engineers, authored the design doc that the team chose as the architecture, took p99 latency from 1.8s to 380ms on the read path, and developed two mid-level engineers into running their own design-doc work.”
Strengths
The behaviours and outcomes that made the work happen. Anchor in evidence: design docs authored that became team direction, engineers mentored through specific growth moments, incident leadership count and post-mortem quality.
- Evidence for: system-design ownership at the service / platform level.
- Evidence for: technical leadership across multi-engineer projects.
- Evidence for: design-doc authoring that shapes team direction.
- Evidence for: mentorship and code-review quality (the team-multiplier work).
Areas for Growth
Forward-looking development edges. Frame as opportunities, not deficiencies. Specific behaviours to develop, not generic software engineer — senior criticism.
- One pattern observed across the period.
- One specific behaviour to develop.
- One concrete next step.
Goals for the Next Period
Two or three concrete goals. Each should name a specific behaviour change, a measurable target, and a deadline. Avoid vague aspirations.
Competencies to evaluate
The 7 competencies a strong software engineer review structures around, in priority order. Use these as the spine of the Strengths and Areas for Growth sections.
- system-design ownership at the service / platform level
- technical leadership across multi-engineer projects
- design-doc authoring that shapes team direction
- mentorship and code-review quality (the team-multiplier work)
- incident leadership and post-mortem rigor
- cross-team coordination on shared infrastructure
- trade-off judgement under ambiguity
Before you write
Senior engineers are force multipliers. Their value is less in lines of code shipped and more in the architectural decisions they steer, the engineers they develop, and the incidents they lead through cleanly. Strong seniors leave the team's codebase materially better than they found it. Weak seniors ship a lot but don't elevate the team around them.
Evidence to gather
Strong reviews for a software engineer cite evidence of these shapes. Only use a specific value (a percentage, a count, a dollar amount) if you actually have it — don’t invent a number to sound concrete.
- design docs authored that became team direction
- engineers mentored through specific growth moments
- incident leadership count and post-mortem quality
- owned services' SLO performance over the period
- PRs reviewed with substantive architectural feedback
- cross-team initiatives led
Where to find the evidence
Work products a software engineer produces. Reference these by name in the review when they’re relevant — it signals you know the work.
- design docs / RFCs / ADRs they authored
- post-mortems for incidents they led
- mentorship notes on engineers they developed
- code reviews on others' design docs
- tech-debt audits or refactoring proposals
- platform / service-level reliability dashboards
Phrasing that lands vs phrasing that doesn’t
Strong — specific, evidenced, role-appropriate
“Led the platform-tier rewrite end-to-end across three engineers, authored the design doc that the team chose as the architecture, took p99 latency from 1.8s to 380ms on the read path, and developed two mid-level engineers into running their own design-doc work.”
Weak — vague, unevidenced, generic
“Strong senior engineer.”
Phrases to never use
Stock filler that AI-written software engineer reviews slip into. Managers spot it instantly. Rewrite to name a specific behaviour instead.
- “strong senior engineer”
- “10x developer”
- “go-to person for hard problems”
- “technical leader”
- “trusted by the team”
- “raises the bar”
- “passionate about engineering”
- “natural leader”
- “rockstar architect”
Don’t invent these specifics
The details an AI tends to fabricate for software engineerreviews. If you don’t have the specific number, name, or date in your notes, leave it out — generic-but-honest beats specific-but- invented every time.
- specific latency / SLO improvements not in input
- named systems or services led
- specific engineers mentored when only counts were given
- named incidents commanded not in input
- particular architecture decisions or technologies not mentioned
- specific design-doc adoption claims not referenced
