Experienced technical backbone for a fast-moving team. Build production systems, architect solutions, and be the quality gate for critical public infrastructure.
What you'll do
- Build and architect production systems
- Review code before it ships; be a quality gate for critical public infrastructure
- Identify and fix AI-generated code patterns that look plausible but are wrong
- Make architectural decisions robust enough for NHS and other high-stakes environments
- Establish code quality standards and testing practices
- Mentor junior engineers on writing maintainable, secure code
Who you are
- 5+ years of software engineering experience, ideally including regulated environments
- You recognise bad code instantly, including AI-generated code that seems fine but isn't
- Deep expertise in JavaScript, Python, and modern web frameworks
- Strong understanding of security best practices and common vulnerability patterns
- You've made architectural decisions you later regretted, and learned from them
- Thorough without being slow. Rigorous review that doesn't block velocity
Young, hungry engineer who treats AI as a core part of their workflow. Build software serving millions through UK government contracts and beyond.
What you'll do
- Build production software using JS/Python and modern frameworks with AI-accelerated workflows
- Develop and deploy machine learning systems that solve real problems
- Ship features end-to-end: from understanding user needs to production deployment
- Work closely with government stakeholders to understand requirements and deliver solutions
- Contribute to REI's core AI agent architecture and tooling
Who you are
- You've built things that work and produce value: side projects, startups, research systems
- AI tools (Claude Code, Copilot, Cursor) are already part of how you code
- Product instinct. You think about users and where value comes from, not just code
- Ideally: ML/AI engineering experience (mechanistic interpretability, training pipelines, etc.)
- Strong fundamentals in JavaScript and Python
- You ship fast and aren't precious about your code
Bridge to the public sector. Navigate UK government procurement, build relationships, and win contracts that deliver real value to citizens.
What you'll do
- Identify and pursue government contract opportunities (£30K–£2M+ range)
- Navigate procurement frameworks: G-Cloud, Digital Outcomes & Specialists, direct awards
- Build relationships with procurement teams, technical leads, and decision-makers across government
- Write compelling proposals and manage the bid process end-to-end
- Guide product development priorities based on market demand
- Shape go-to-market strategy for UK government and eventually Canada/US
Who you are
You have direct experience with UK government software procurement from one of these backgrounds:
- Government-side: Worked in UK government (GDS, CDDO, NHS Digital, a department digital team) and used the procurement system to acquire software services
- Supplier-side: Worked at a software consultancy winning government contracts with a track record of successful bids
- Bonus: startup drive, technical background, SMB sales experience, or experience navigating bureaucracy in complex organisations
