- Build and maintain CI/CD pipelines for automated testing and deployment
- Work with containerization (Docker) and orchestration (Kubernetes) where applicable.
- Write and maintain unit, integration, and end-to-end tests (pytest, unittest or equivalent)
Cross-functional & delivery
- Communicate proactively with the client's technical and non-technical stakeholders on progress, risks, and design tradeoffs
- Participate in sprint/PI planning and translate high-level or ambiguous requirements into concrete technical designs and acceptance criteria

- CI/CD - experience building or maintaining pipelines
- Strong communication skills - able to explain technical tradeoffs to non-technical stakeholders and write clear documentation
- Problem-solving and debugging - comfortable diagnosing issues across the full stack, from frontend rendering to backend performance to infrastructure
Nice to Have
