The DX team’s mission is to make engineering at UserTesting fast, reliable, and enjoyable. We build and evolve the internal platforms, tools, and workflows that hundreds of engineers rely on every day to develop, test, and ship software with confidence. This is a great opportunity for an engineer who enjoys working on shared systems, cares deeply about developer usability, and wants to have impact at scale.

What You’ll Do

• Build, operate, and improve developer-facing tooling and platforms such as CI/CD systems, developer portals, artifact repositories, and deployment tooling.
• Identify friction in the development lifecycle and drive pragmatic improvements through automation, templates, and self-service workflows.
• Design, build, and evolve CI/CD pipelines (GitHub Actions, CircleCI, ArgoCD, or similar) that support multi-service, multi-environment deployments.
• Create and maintain Helm charts and Kubernetes manifests to standardize and simplify service deployments.
• Develop and maintain Infrastructure as Code (IaC) using Terraform to ensure infrastructure is consistent, repeatable, and easy to reason about.
• Partner with application teams to understand their needs and incorporate feedback into platform improvements.
• Improve reliability and confidence in delivery through observability, monitoring, and sensible defaults.
• Research and evaluate new tools and approaches, clearly documenting trade-offs and recommendations.
• Contribute to architectural discussions around scalability, resilience, and cost awareness, with a focus on real-world usage.
• Write clear documentation, guides, and runbooks that help other engineers succeed independently.
• Support teammates through collaboration, knowledge sharing, and mentoring, contributing to a culture of learning and continuous improvement.

What We’re Looking For

• Mid-level engineer with strong fundamentals, sound judgment, and a service-oriented mindset focused on improving the day-to-day experience of other engineers.
• Hands-on experience building or operating shared systems and tooling, including CI/CD pipelines, Kubernetes-based deployments (e.g., Helm), Infrastructure as Code (Terraform preferred), Cloud environments (AWS preferred).
• Comfortable scripting and automating workflows using languages such as Node.js, Python, Go, or Bash.
• Solid understanding of service reliability practices, including incident response, postmortems, and SLOs.
• Strong empathy for fellow engineers with clear communication and a pragmatic approach to problem-solving.
• Able to balance ideal solutions with real-world constraints and iterate effectively based on feedback.
• Deep care for usability, clarity, and adoption of the systems and tools you build.
• Experience building internal platforms or self-service tooling is a strong plus.
• Prior experience as a product software engineer (backend or fullstack) is a plus, enabling better understanding of real-world developer workflows.
• Familiarity with observability tooling, internal developer platforms (e.g., Datadog IDP, Backstage), and GitOps workflows is beneficial but not required.
• Exposure to DevSecOps, FinOps, or distributed systems concepts (e.g., multi-region systems, service mesh) is a bonus.

• Impact is measured by adoption and usefulness.
• Feedback is welcomed and acted upon.
