• Build scalable, production‑ready software and integrations.
• Act as an AI Developer Advocate by delivering demos, workshops and presentations to engineering leadership and C‑suite audiences.

• Comfortable operating in R&D and early‑stage environments.
• Strong communicator able to explain AI concepts to engineers and executives.
• Passionate about developer experience, code quality and innovation.
• Enjoys mentoring and raising the engineering bar for others.

Required skills

• Proficiency with modern AI tooling such as GitHub Copilot, Claude and OpenAI/Codex‑style tools.
• Strong knowledge of RESTful APIs, web standards and security principles.
• Java (JDK 17+ / Spring Boot), Python and shell scripting.
• Front‑end expertise with React (ideally Next.js) or Angular.
• Containerisation and orchestration using Docker and Kubernetes.
• CI/CD pipeline implementation, SonarQube and Prisma.
