- Experience extracting or bypassing functionality from large, heavily coupled codebases behind behavior-preserving contracts.
- Fluency with TypeScript and Node.js; comfort with edge runtimes.
- Experience with monorepo tooling at scale, such as Nx or Turborepo, and build-graph correctness.
- Experience with codebase migration engineering, including verifying generated output and preserving existing behavior.
- Platform engineering experience involving product-team customers and adoption measurement.
- Ability to work across cloud boundaries and evaluate latency and cost tradeoffs.
- Strong written technical communication.
- Proactive adoption and application of AI and emerging technologies.

## Benefits
