• Investigate and resolve production issues, including connectivity problems, to maintain product stability.

• Share reusable team processes and evaluate when to adopt dependencies or build solutions internally.

What We're Looking For

• Two to five years of experience in full-stack product engineering, with strong frontend experience.

• Experience building and shipping polished, customer-facing web features using React and TypeScript.

• Production experience with Go is valued; familiarity with Postgres, Redis, PubSub, RPC, S3, or Temporal is also relevant.

• A track record of contributing to medium- to large-scale projects, including owning a project through design and deployment.

• Experience building or maintaining high-traffic products, with a focus on reliability and measurable user impact.
