Senior Platform Engineer, Internal Developer Platform & Developer Experience

The Opportunity

At UserTesting, the Developer Experience (DX) team builds and operates the Internal Developer Platform (IDP) that engineers use to build, test, ship, and operate software.

Our goal is simple: make it easy for engineers to ship high-quality software quickly and safely through self-service, well-defined paved roads, and fast feedback loops.

We treat the platform as a product: engineers are our users, and adoption, usability, and measurable impact matter as much as technical excellence.

This role focuses on owning and evolving the Internal Developer Platform at scale, including software delivery systems, service lifecycle workflows, and platform APIs.

You will also help define and build an Agentic Developer Platform, applying AI through structured, enterprise-grade workflows that improve developer productivity (e.g., debugging assistance, delivery insights, and safe automation with guardrails).

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

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

• Agentic future: Build real, production-grade AI capabilities into the developer workflow
