This role sits across full-stack engineering and platform-aware development, you’ll be working with Python and Node.js on the backend, React on the frontend, and helping shape how applications run, scale and are observed in production.

  • Contribute to and improve CI/CD pipelines and release processes

  • Implement observability practices (logging, monitoring, tracing)

  • Apply secure coding practices and ensure systems meet required standards

  • Troubleshoot issues across application and infrastructure layers

  • Collaborate with engineers, designers, and clients to deliver production-ready systems

Required

  • Experience building production systems using Python and/or Node.js

  • Strong experience with TypeScript and React

  • Experience building and consuming REST or GraphQL APIs

  • Exposure to AWS and/or Azure environments

  • Familiarity with containers (Docker) and orchestration (Kubernetes beneficial)

  • Experience working with CI/CD pipelines

  • Understanding of observability concepts (logging, monitoring, tracing)

  • Solid understanding of software engineering fundamentals and system design

  • Awareness of secure coding practices and data protection considerations

Nice to Have

  • Strong experience with Kubernetes in production environments

  • Experience with specific observability tools (e.g. Datadog, New Relic, Prometheus, etc.)

  • Experience with Infrastructure as Code

  • Exposure to distributed or event-driven systems

  • Experience working in a consulting or client-facing environment

  • Familiarity with stricter security or compliance frameworks (e.g. regulated environments, access-controlled systems)
