5+ years of backend or platform engineering experience, with at least 2 years building developer-facing products (SDKs, APIs, integrations, or open source libraries that external engineers consumed) Preferable to have worked at or with AWS, Microsoft Azure or Google Cloud specifically on dev related products Shipped production integrations with third-party platforms - point us to the code, the package, or the partner that went live because of you Practical, hands-on fluency with MCPs and SDKs Strong API design instincts - knows when to wrap vs. expose, when to version, when to break compatibility, and how to make errors that explain themselves Comfortable in customer-facing technical conversations - can scope an integration with a partner's principal engineer in a 30-minute call and walk out with a working spec Ships fast under ambiguity - has a track record of going from "partner asked for X" to "something working" in days, not sprints Owns the full lifecycle: design, code, docs, release, support. No throwing things over the wall. Bonus: Has contributed to or shipped something in the public developer ecosystem that you're proud of
