The Opportunity

We are supporting a client operating within a highly regulated environment and looking to engage an experienced contract engineer to join a critical delivery programme

This is an opportunity to join a fast-paced engineering team focused on delivering high-quality software solutions where hands-on development, AI-assisted engineering, and structured delivery practices are central to success.

What We're Looking For

Successful candidates will have experience working within heavily regulated or enterprise environments and be comfortable operating within formal governance frameworks, change controls, ticketing processes, and established development lifecycles.

You'll bring:

• Proven experience delivering software solutions in regulated environments
• Strong AI literacy and practical experience using AI-powered development tools
• Experience building and delivering AI-enabled solutions
• Hands-on experience with Claude Code in day-to-day engineering activities
• Excellent communication skills and the ability to work effectively within distributed teams
• A collaborative approach to code reviews, quality assurance, and secure development practices

Senior Full Stack Engineer

We're seeking an experienced Full Stack Engineer with a strong software engineering background who enjoys building robust, scalable solutions across both backend and frontend technologies.

Essential Skills

• Strong Python development experience
• FastAPI, API design, middleware, and asynchronous development patterns
• Pydantic and schema validation
• PostgreSQL database design, migrations, and query optimisation
• React and TypeScript
• Authentication and authorisation (SSO, JWT, RBAC)
• Automated testing using pytest and JavaScript testing frameworks
• Git/GitHub workflows, pull requests, and CI processes
• Secure coding practices and security remediation
• Hands-on experience with Claude Code and AI-assisted development workflows

Ideal Background

We're particularly interested in candidates from a strong software engineering background who are actively involved in designing, building, and delivering production code. These opportunities are best suited to engineers who enjoy creating features, solving business problems through software, and operating within high-performing development teams, rather than purely infrastructure or platform-focused professionals.
