Description
What you'll do
As a Senior Software Engineer at Cursor, you will lead discovery with customer engineers to identify real bottlenecks and define clear success metrics.
You will design and build Cursor-powered workflows, such as large-scale refactors, migrations, PR review loops, incident → fix pipelines, and spec → implementation systems.
Your goal will be to ship a fast first version in days, then harden it into something reliable over weeks with proper rollout plans, monitoring, and iteration based on real usage.
You will own production quality, including tracing, evals, metrics, debugging model behavior, latency/cost tradeoffs, and failure modes.
You will work directly with Staff+/Platform/Eng leaders, going deep in code while also communicating clearly about tradeoffs and results.
You will turn what you build into reusable patterns and push improvements back into the core Cursor product.
You may be a fit if
You thrive in ambiguity and can turn fuzzy problems into clear scopes and shipped systems.
You've built and owned AI-native workflows in production, not just prototypes, and have debugged real-world model failures.
You're comfortable leading discovery conversations and being accountable for customer outcomes.
You build end-to-end. If it needs frontend, backend, infra, or prompt iteration, you'll own it.
You've handled production reliability before, including metrics, alerts, safe rollouts, and incident response.
You're strong in Python and TypeScript/JavaScript and can ramp quickly on new stacks.
