AI-assisted and agentic development is reshaping what engineers do day to day. We will allow good engineers to build and evolve their skills into the roles of the future. What you'll bring You will demonstrate proficiency in the majority of the requirements below, along with the attitudes and behaviours that make a great engineer on our team. Technical Core Engineering Stack: Proficiency in most of our core technologies (Java, Spring / Spring Boot, JavaScript / TypeScript frameworks such as React or Angular, and SQL), with a willingness to learn others. Experience with Python is desirable but not essential. Agentic Engineering: Proven experience using agentic coding workflows and modern AI tools (e.g., Copilot, Claude, Codex, Cursor) to plan, build, refactor, and document complex systems. You can discuss the role of judgement in agentic engineering: when to delegate to an agent, how to verify its output, and where human accountability remains. AI-Assisted Troubleshooting: Experience using AI tools to analyse metrics and logs across observability platforms (e.g., New Relic, OpenSearch / Kibana, Coralogix). Cloud & Delivery: Familiarity with containerised, distributed cloud environments (e.g., Docker, Kubernetes, AWS), Infrastructure as Code (Terraform), and CI/CD pipelines (e.g., GitHub Actions, Jenkins), alongside solid version control (Git). Growth, leadership & collaboration Rapid Learning: A proven track record of learning new skills effectively and rapidly. Mentorship & Leadership: Actively mentors and teaches junior engineers, and actively drives discussions to improve working practices and code quality. Collaboration: Real-world Agile experience (Scrum/Kanban) and clear communication across disciplines, including product and UX. ## Description Senior Agentic AI Full-Stack Software Engineer (Java & React / JavaScript / Angular / Claude Code / Codex) Would you like to help create products to support the sharing of scientific knowledge?
