Senior Infrastructure Engineer

Location: Zurich, Switzerland

Department: Product

Location Type: IN_OFFICE

Employment Type: FULL_TIME

What excites you

• Full ownership: Owning the complete infrastructure of a company that moves clinical trial data for dozens of customers.
• Fixing things for good: Working through a real backlog and removing root causes so the same problems stop coming back.
• AI-native operations: Directing AI agents to do infrastructure work is already how you operate, and you want an environment that pushes it further.
• Improving a live system: Making an existing platform cheaper, faster, and more reliable step by step, rather than rebuilding it from scratch.
• Defining a function: Shaping what infrastructure at Rivia becomes as the company grows.

Responsibilities

• Own our AWS platform end to end across staging and production: EKS, RDS, MemoryDB/Redis, S3, DynamoDB, IAM, networking.
• Understand and reduce our infrastructure costs, from the Spark data pipeline to backups, and keep unit economics improving as customer volume grows.
• Own CI/CD and developer productivity: faster pipelines, fewer flaky tests, better internal tooling.
• Keep our Kubernetes workloads stable and scalable, including the services behind our AI features.
• Run identity and secrets management: Keycloak, SSO, OIDC.
• Build AI-agent workflows for infrastructure work, such as recurring audits of AWS for cost, security, and performance findings.
• Support external penetration tests and provide infrastructure evidence for ISO 27001 and client audits.
• Document core systems and runbooks so the platform does not depend on any single person.

What Excites us

• Experience as the sole or first infrastructure owner at a startup.
• 5+ years of hands-on infrastructure or DevOps experience with deep AWS expertise, including cost optimization work.
• Production Kubernetes operations experience.
• A proper software engineer: you write production-quality code and can diagnose and fix problems inside application codebases when needed (JVM experience a plus).
• You have owned complex CI/CD end to end (GitHub Actions or equivalent).
• An AI-native way of working: you use agents (Claude Code or similar) for real infrastructure work and can show concrete examples.
• Comfortable being the only infrastructure specialist on the team: self-directed, you find and fix problems without being asked.

• Keycloak or similar identity provider operations (OIDC, SSO, secrets management).
• Spark or large-scale data pipeline infrastructure experience.
• Exposure to regulated environments (ISO 27001, audit support).
• Datadog or a comparable observability stack.

Our Values
