Test Automation, CI​/CD & Platform Infrastructure Engineer

Are you the kind of person who feels proud when deployments become routine and production behaves exactly as expected? Do you enjoy turning “it worked on my machine” into repeatable pipelines, clear test signals, solid monitoring, and secure defaults that eliminate nasty surprises in demos and with customers? Can you keep things practical while still holding the bar high—helping the team move faster precisely because things break less?

If that sounds like you, let’s talk.

Omnilex is a fast-moving AI legal tech startup born out of ETH Zurich. Our interdisciplinary team of 14+ people builds tools that help lawyers and in-house legal teams research faster and answer complex legal questions with confidence. What makes us different is how we blend multiple data sources—public/external materials, customer-internal knowledge, and our own AI-first legal commentaries—into a product that tackles real-world legal complexity.

As a Test Automation, CI/CD & Platform Infrastructure Engineer (QA Automation, Dev Ops, Dev Sec Ops ) you will drive “shipping confidence” end-to-end: tests, releases, environments, observability, migrations, and security-by-default.

• Test strategy & execution: design and roll out a “happy path” testing approach (unit, integration, E2E) for the workflows that truly matter.
• Pipeline engineering: build CI that’s fast, stable, and readable—clear failures, minimal flakes, and no progress blocked by randomness.
• Release & deployment automation: implement safe deploy flows, stage promotion, rollbacks, and automated release notes.
• Operational reliability: strengthen observability (logs, metrics, traces), alerts, incident practices, and early detection of “demo-killers.”
• Secure-by-default foundations: bake in strong defaults (secrets management, least privilege, dependency scanning, baseline threat awareness) as part of everyday engineering.
• Migration discipline: create repeatable, low-risk migration processes and playbooks across environments and customer-specific database splits.
• Environment cleanliness: reduce stale data/code paths (demo accounts, abandoned pages, old fixtures) and introduce lifecycle rules that keep things fresh.
• Cross-team alignment: work with engineering and business to define what must never fail, how we validate it, and what we watch in production.

In your first months you will: map out the biggest reliability and security gaps, establish the testing + release “golden path,” and measurably cut the most common production and demo surprises.

• Practical experience in QA automation / Dev Ops / SRE for a production SaaS product.
• Strong CI/CD skills and real-world test automation experience (integration + E2E, not just unit tests).
• Proven ability to investigate and improve production behavior (logs, alert tuning, incident follow-ups/postmortems).
• Solid security fundamentals for product teams (secrets, access control, dependency hygiene).
• Comfortable with modern web + data stacks (Docker, Postgre
  
  SQL, service-to-service setups).
• Ownership mentality, clear communication, and a willingness to define better workflows—not just follow them.
• Proficiency in English.
