What We’re Looking For
- Strong experience owning and delivering production systems or platforms end‑to‑end.
- Experience building or evolving Internal Developer Platforms, CI/CD systems, or developer tooling ecosystems.
- Ability to design for self‑service, adoption, and developer usability, not just technical correctness.
- Proficiency in Node.js, Python, or Go.
- Experience with cloud infrastructure and containerized environments.
- Strong systems thinking across software delivery, observability, and automation.
- Ability to navigate ambiguity and drive technical direction independently across teams.
- Product mindset: you care about developer experience, adoption, and measurable outcomes.
Nice to Have:
- Experience with Kubernetes, Terraform, or AWS.
- Experience improving software delivery performance at scale (e.g., lead time, reliability, deployment safety).
- Background in backend or distributed systems.
- Familiarity with observability practices and feedback loop design.
- Experience applying AI to engineering workflows, including LLM‑powered agents, developer assistance systems, and automated workflows with built‑in safeguards and evaluation.
Why This Role
- Own the platform: shape and evolve the Internal Developer Platform used across UserTesting.
- High impact: your work defines how engineering teams build, ship, and operate software.
- Platform as a product: influence roadmap, adoption, and developer experience end‑to‑end.
