I’m hiring a Lead Engineer to take full technical ownership of a high-impact, public-facing platform used across the UK public sector to meet statutory climate reporting requirements.

This is a chance to own the architecture, drive delivery, and shape a national service with real environmental impact. You’ll operate with huge autonomy and work directly with design, product, and policy teams. If you like building meaningful systems and making big decisions, you’ll love this.

What You’ll Do

• Lead the build of a complex reporting platform end-to-end
• Own front-end + API integration, dynamic forms, validations, workflows, and exports
• Make key architectural decisions that set the direction for the entire system
• Work independently and run your own delivery cadence
• Align with cloud teams on integration, APIs, and infrastructure
• Ensure high standards: accessibility, security, performance, reliability
• Turn legislative requirements into clean, intuitive digital journeys

What We’re Looking For

• 6+ years engineering, including 2+ in a senior/lead role
• Deep experience in React, TypeScript, Node, and scalable app architecture
• Strong background building structured, form-heavy, data-driven UIs
• Comfort working in secure cloud environments (AWS ideal)
• Strong accessibility + usability grounding (WCAG 2.1)
• Someone decisive, product-minded, and happy leading with minimal oversight
• Bonus: experience with public-sector design systems or climate/sustainability work

Why This Role Matters

• You’ll lead a national digital service used across the public sector
• Your decisions will shape a platform that supports real climate outcomes
• You’ll work closely with policy, design, and domain experts
• Huge scope, huge autonomy, and genuine impact
