Comfortable working across the full software delivery lifecycle (build, deploy, operate)
Strong understanding of software engineering fundamentals and best practices
Experience contributing to technical design and architectural decisions
Ability to take ownership and drive technical solutions from concept to delivery
Interest in modern AI-enabled engineering practices and continuous improvement
Nice to Have

Exposure to containerisation and orchestration technologies such as Docker and Kubernetes
Familiarity with CI/CD tooling such as GitHub Actions, GitLab CI, or Azure DevOps
Experience working in cross-functional, agile product teams
Experience integrating AI services, LLMs, or agent-based systems into software products
