You should be comfortable working independently in a fractional environment. We’ll provide clear priorities and technical review, but we expect you to investigate problems, communicate clearly, and move work forward without continuous supervision. This is a good fit for an experienced engineer who wants a stable, ongoing US startup client alongside other independent work. Please apply as an individual contractor, not through an agency.

- Experience deploying and debugging applications on Vercel
- Comfortable with Git, short-lived feature branches, pull requests, and feature flags
- Able to diagnose third-party API integrations, including retries, failures, and rate limits
