12-month contract | Immediate start | Likely extension

We're looking for an experienced Full Stack Engineer to join a high-performing product engineering team building user-facing, AI-powered applications. This is a hands-on role focused on designing and delivering robust, scalable software rather than pure ML or data engineering. You'll work on end-to-end features within an agentic application environment, contributing to real-world, production-grade systems that are already live and evolving.

What you'll be doing

• Designing and building end-to-end user-facing features
• Working across frontend and backend within a modern cloud-based architecture
• Improving reliability, scalability, and performance of existing applications
• Contributing to technical design and architectural decisions
• Collaborating closely with product, engineering, and research stakeholders
• Building features such as recommendations, user profiles, and other customer-facing functionality
• This is a software engineering role, not a data engineering or ML research position.

Essential

• Strong experience with JavaScript and Python
• Solid cloud experience (GCP preferred; Azure acceptable)
• Full stack development experience across frontend and backend
• Comfort working in containerised environments

Nice to have

• Kubernetes
• Cloud deployment and CI/CD exposure
• React or Next.js
• Experience contributing to system and application design (not just delivery)

What we're looking for

• Experience as a software or full stack engineer
• Execution-driven, proactive mindset
• Comfortable forming and voicing technical opinions
• Experience working in agile teams
• Interest in working on scientific or research-led products
• Able to slot into an existing team and add value quickly

Why this role?

• Work on cutting-edge, real-world AI-enabled products
• Freedom to put your own ideas into practice
• High-impact work that's challenging and rewarding
• Unlimited token budget and modern tooling
• Strong track record of contract extensions and contract-to-perm opportunities
• Collaborative, ambitious engineering culture
