About the role

  • Senior Infrastructure & Platform Engineer at UserTesting designing AWS infrastructure and Kubernetes clusters. Focused on building internal platform abilities and improving developer experience through self-service.

Responsibilities

  • Design, build, and maintain AWS infrastructure using Terraform, reusable modules, and modern IaC patterns.
  • Develop and operate Kubernetes (EKS) clusters, ensuring scalability, cost effectiveness, and secure-by-default configurations.
  • Shape and evolve internal platform capabilities: golden paths, templates, and self-service tooling that enable engineering teams to ship faster and safer.
  • Enhance and standardize CI/CD experiences using GitHub Actions to promote consistency, reliability, and high developer satisfaction.
  • Implement policy-as-code and automated guardrails that embed security, cost controls, and operational excellence into the platform layer.
  • Build and maintain shared monitoring, metrics, and logging foundations (Prometheus, Grafana, Datadog, etc.).
  • Work closely with product engineering teams to understand friction points and co-design abstractions that simplify complex infrastructure concerns.
  • Improve internal documentation, onboarding guides, and developer experiences that scale through self-service, not manual support.

Requirements

  • 7+ years in Infrastructure, SRE, DevOps, or similar roles supporting cloud-native SaaS environments.
  • Deep proficiency with AWS services (compute, networking, IAM, storage) and Kubernetes at production scale (preferably EKS).
  • Expertise in Terraform, GitHub Actions, and automation-first workflows.
  • Strong scripting ability (Python, Bash) and hands-on experience with observability tooling.
  • A platform-product mindset: you care about user experience, maintainability, and measurable improvements to developer velocity.
  • Passion for automation, well-designed abstractions, and building systems that scale with adoption—not headcount.
  • Ability to partner effectively across teams, communicate clearly, and influence through technical leadership.
  • Commitment to reliability, security, and performance as built-in characteristics—not afterthoughts.

Benefits

  • Flexible work arrangements
  • Professional development opportunities
