✅ What We’re Looking For Required:

• Strong hands-on experience with AWS, with additional exposure to GCP or Azure a plus. • Proficiency with Terraform and infrastructure-as-code principles. • Experience managing Kubernetes clusters and containerized applications. • Familiarity with CI/CD pipelines and modern DevOps tooling. • Experience with observability tools (e.g. Datadog, Prometheus, Grafana). • Strong scripting skills (e.g. Bash, Python).

• Ability to contribute to architectural planning and system design. • Excellent problem-solving and analytical skills, especially in complex or ambiguous environments.

Nice to Have

• Experience with Elasticsearch in production. • Exposure to AI/ML infrastructure or data/compute-heavy environments. • Working knowledge of cloud architecture and distributed systems. • Experience with databases such as PostgreSQL, MySQL, MongoDB, and Redis. • Experience working directly with internal or external customers to support and troubleshoot complex systems. • Background in a startup or high-growth tech environment.

Why Join Causaly?

• Meaningful mission – Accelerate life-saving scientific discoveries. • Modern tech stack – AWS, Kubernetes, Terraform, CI/CD, and more. • Hybrid working – 3–5 days per week onsite at our central London office (Farringdon). • Collaborative culture – Work with smart, kind people who care deeply about what they do. • Great benefits – Private medical & dental insurance, pension scheme, wellness and learning budgets, and regular team events.
