Integrate third‑party services, authentication systems and enterprise connectors
Collaborate with product and design to craft intuitive user experiences and smooth interaction flows
Deploy and manage containerised applications using Docker and Kubernetes
Work with databases such as Postgres, Redis and/or ClickHouse – handling schema design, migrations and query performance
Implement and maintain CI/CD pipelines, testing frameworks and release workflows
Troubleshoot production issues, performance problems and service reliability incidents
Take full ownership of features from design to production, including documentation and monitoring
What We’re Looking ForWe’re looking for a highly skilled engineer with strong full‑stack fundamentals, proven delivery experience and the ability to build elegant, scalable systems across the entire web stack.
