- Drive architectural decisions and contribute to long-term technology strategy.
- Design APIs, services and database solutions that support business growth.
- Build and maintain robust CI/CD pipelines and modern deployment practices.
- Mentor and coach engineers while promoting engineering best practices including clean architecture, TDD and continuous delivery.
- Lead Agile ceremonies, technical planning and cross-team collaboration.
- Resolve complex technical issues and lead critical incident response.
- Identify opportunities to leverage AI to improve products, engineering processes and customer outcomes.
- Champion secure software development, continuous improvement and responsible AI adoption across the engineering function.
What You'll Bring
Essential Experience & Technical Skills
You'll have strong experience in:

- CI/CD pipelines and DevOps practices.
- Secure software engineering and GDPR-aware development.
- SQL and NoSQL database design and optimisation.
- Monitoring, observability and production diagnostics.
- Agile software delivery environments.
You’ll also be comfortable using modern AI-assisted engineering tools such as Claude, Codex or Cursor, with a working understanding of modern AI engineering practices, including the use of hooks, agentic loops and harnesses to guide, constrain and evaluate AI output. You’ll understand both their opportunities and limitations, and ensure secure and responsible adoption.
Desirable Experience
It will be highly beneficial if you have hands-on experience productionising AI-generated code, taking it through review, testing, security and quality gates and into live, supported services, with clear human accountability for what ships.
