The Role

We’re looking for a Mid-Level Software Engineer to join a team building and scaling a modern, enterprise-grade GenAI platform.

This is a frontend-leaning full-stack role, with a strong focus on React and TypeScript. You’ll spend most of your time building high-quality user experiences, while also contributing across the stack, particularly in Python and working closely with cloud infrastructure to ensure systems are scalable, observable, and production-ready.

You’ll be part of a team embedding AI capabilities into real-world workflows focusing on performance, usability, and reliability at scale.

What You’ll Be Doing

  • Build modern, responsive web applications using React and TypeScript
  • Design clean, scalable UI architectures and reusable component systems
  • Contribute to backend services, primarily in Python (with Node.js where needed)
  • Integrate with REST and/or GraphQL APIs
  • Work closely with cloud platforms (AWS and/or Azure) to design and operate scalable systems
  • Deploy and manage applications in containerised environments (Docker, Kubernetes)
  • Improve CI/CD pipelines and delivery workflows
  • Implement observability practices (logging, monitoring, tracing)
  • Apply secure coding practices and support data protection requirements
  • Troubleshoot issues across application and cloud infrastructure layers
  • Collaborate with engineers, designers, and stakeholders to deliver production-ready systems

What We’re Looking For

  • Strong experience with React and TypeScript (core focus)
  • Solid experience with Python for backend development
  • Experience building production-grade web applications across the stack
  • Strong understanding of frontend performance, state management, and component-driven design
  • Experience working with cloud platforms (AWS and/or Azure)
  • Experience integrating with REST or GraphQL APIs
  • Familiarity with containerisation (Docker, Kubernetes beneficial)
  • Experience working with CI/CD pipelines
  • Understanding of observability concepts (logging, monitoring, tracing)
  • Strong foundation in software engineering principles and system design
  • Awareness of secure coding practices and data protection considerations

Nice to Have

  • Experience with Node.js
  • Experience running applications on Kubernetes in production
  • Familiarity with observability tooling (e.g. Datadog, Prometheus, New Relic)
  • Experience with Infrastructure as Code
  • Exposure to distributed or event-driven architectures
  • Experience working in client-facing or consulting environments
  • Familiarity with security-conscious or regulated environments
