You'll bring:

 * Proven experience delivering software solutions in regulated environments
 * Strong AI literacy and practical experience using AI-powered development tools

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 Back End and Front End 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.
