• Strong Python programming background, delivering production-ready code
• Proven experience working on distributed systems using managed cloud services (AWS preferable)
• Confident provisioning modern cloud infrastructure with Terraform
• Hands-on experience with CI/CD pipelines (GitLab CI preferable)
• Ability to evaluate the pros and cons of different technologies (e.g. SQL vs NoSQL databases)
• Strong track record in test automation and a quality-first engineering mindset
• Comfortable working in agile squads with a DevOps culture
• A familiarity with how Non-Functional Requirements impact the design of a system
• Excellent communication skills, able to work across cross-functional teams
