As a Quality, Reliability and Security Engineer (Dev Ops, QA, Dev Sec Ops ) you will own shipping confidence across testing, deployment, monitoring, migrations, and security‑by‑default.

• Testing system ownership: define and implement the testing “golden path” (unit, integration, E2E) for critical workflows.
• CI automation: build reliable pipelines that run fast, fail clearly, and prevent flaky tests from blocking progress.
• CD and release engineering: automate safe deploys, environment promotion, rollbacks, and release notes.
• Prod stability: improve observability (logs, metrics, traces), alerting, incident hygiene, and “demo‑killer” detection.
• Security by design: embed secure defaults (secrets, least privilege, dependency scanning, basic threat awareness) beyond just compliance.
• Data migrations: create repeatable migration workflows and playbooks for multi‑environment and customer database splits.
• Environment hygiene: reduce outdated code/data (demo profiles, dead pages, stale test fixtures) and enforce lifecycle policies.
• Collaboration: align with engineers and business on what must work, how we test it, and what we monitor.

In your first months you will: establish a baseline of reliability and security risks, implement the testing and release golden path, and reduce the most frequent production surprises with measurable improvements.

• Hands‑on experience in Dev Ops/SRE/QA automation for a production SaaS product.
• Strong skills in CI/CD and test automation (integration and E2E, not only unit tests).
• Experience with monitoring and debugging production issues (log analysis, alert tuning, postmortems).
• Solid security fundamentals for product teams (secrets handling, access control, dependency hygiene).
• Comfort working with modern web stacks and databases (Docker, Postgre
  
  SQL, service‑to‑service systems).
• Ownership mindset, clear communication, and willingness to define and improve workflows.
• Proficiency in English.
• Availability full‑time. On‑site in Zurich at least two days per week (hybrid).

• Experience with Azure infrastructure and services (IaC, identity, networking, observability).
• Familiarity with our stack:
  Type Script, Node.js, NestJS, Next.js
  .
• Practical experience with ISO 27001 environments or security auditing support.
• Experience testing and operating AI‑powered systems (nondeterminism, rate limits, flaky dependencies).
• You have a Swiss work permit or EU/EFTA citizenship.
• Working proficiency in German
  .

• Direct impact: your work reduces incidents, prevents demo failures, and increases customer trust.
• Autonomy & ownership: you own the foundations of shipping confidence and security defaults.
• Team: work with a sharp, interdisciplinary team at the intersection of AI and law.
• Compensation: CHF 7 000–11 000 per month + ESOP (employee stock options), depending on experience and skills.
