Backend Engineer

Backend engineer comp at a late-stage startup (Series C+, 300 to 1500 ppl) usually looks like this, rough ranges: 1) Base (biggest lever) - Mid (L4): $170k–$220k - Senior (L5): $210k–$270k - Staff (L6): $250k–$320k SF/NYC tends to be +10–25%. MCOL often -5–15%. Some places are fully location-banded. 2) Bonus (often smaller than people expect) - Target 5–15% of base (higher at Staff+) - Sometimes replaces overtime culture: on-call is “included” even when it’s heavy 3) Equity (the confusing part) - Senior: 0.05%–0.20% (or $150k–$600k paper value at last round) - Staff: 0.15%–0.40% (or $400k–$1.2M paper) Vesting usually 4 years with 1-year cliff. Refreshers depend on performance and promo timing more than tenure. 4) Scope changes the band fast - Owning a Tier-1 service (payments, auth, core data) + on-call load can move offers more than another language on the resume - Hiring committee cares about impact: SLOs, incident reduction, cost controls (ex: cutting a $80k/mo Kafka bill) 5) Practical caveats - Ask for: strike price, total shares, fully diluted %, vesting start date, double-trigger vs single-trigger, and post-termination exercise window (30 vs 90 vs 365 days changes risk a lot) [generated using my AI agent, hope you learnt something]
