Senior Platform Engineer, Internal Developer Platform & Developer

What You’ll Do

• Own the Internal Developer Platform (IDP) as a product, including roadmap, platform capabilities, and developer‑facing workflows.
• Design and evolve the software delivery lifecycle, including CI/CD, automated validation, release orchestration, and rollback mechanisms.
• Build and maintain paved‑road workflows that enable self‑service for common tasks (service creation, environment provisioning, deployment, observability, incident response).
• Define and manage a platform service catalog and APIs, enabling discoverability and standardization across teams.
• Improve developer feedback loops by strengthening observability, diagnosability, and actionable signals across build and runtime systems.
• Establish platform guardrails and standards that balance consistency with team autonomy.
• Drive adoption of platform capabilities through usability, documentation, and close collaboration with engineering teams.
• Build and operate an Agentic Developer Platform that applies AI to delivery insights, workflow automation, developer assistance, and safe, policy‑aware actions.
• Ensure AI‑powered workflows include clear boundaries, human‑in‑the‑loop controls where needed, and observable outcomes.

• 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.
• Nice to Have:
  Experience improving software delivery performance at scale (e.g., lead time, reliability, deployment safety).
• Nice to Have:
  Background in backend or distributed systems.
• Nice to Have:
  Familiarity with observability practices and feedback loop design.
• Nice to Have:
  Experience applying AI to engineering workflows, including LLM‑powered agents, developer assistance systems, and automated workflows with built‑in safeguards and evaluation.

Own the platform: shape and evolve the Internal Developer Platform used across User Testing.

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.

Agentic future: build real, production‑grade AI capabilities into the developer workflow.
