Senior Platform Engineer building scalable backend and cloud infrastructure for ExaCare’s AI - powered post - acute care platform. Improving reliability, developer velocity, and healthcare admission workflows.
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
