## About the Role

* 5+ years of commercial full-stack experience in JavaScript or TypeScript: Node.js, React or Next.js, and Postgres or similar. Strapi or another headless CMS is a plus.
 * Working Python, confident maintaining FastAPI services and data pipelines.
 * Experience putting an LLM-powered feature into production, refining it and fixing what went wrong.
 * Ownership of a production system and its architectural calls.
 * Technical leadership: reviewing code, setting standards and improving how a team ships, with or without the title.
 * AI-first ways of working, with the judgement to know when to trust AI tools.
 * Clear communication with non-technical colleagues and funders.

Nice to have

 * Job board or skills matching platforms.
 * SEO, structured data and Google for Jobs.
 * Accessibility for low digital confidence or mobile-first users.
 * An interest in social impact, green skills or widening access to good work.

## Description

You will own our proprietary job matching technology: how it is built, how it runs and where it goes next. As our most senior engineer, you will manage our long-term offshore development team, working with our COO (product owner), with budget for AI tooling and extra capacity.

Our live stack: two job platforms (Net Zero Careers and Good Work London) on Next.js, React, Strapi and Postgres; an LLM-enriched job sourcing pipeline; agentic AI services in LangGraph and FastAPI; and analytics services.

Demand is growing fast, with new NHS, youth employment and college programmes all needing platforms soon.

Two strands, running side by side:

 * Strengthen and scale (next six months). Upgrade to Strapi v5 and current Node, add testing and release practice, meet public sector security standards and launch new sites from one codebase.
 * Build what comes next. Lead the design and build of our next-generation national, multi-programme platform.

What you will do

 * Architecture. Own technical design: one codebase, configuration over copies, features behind flags, and documentation.
 * Data pipelines and AI. Own the job sourcing pipeline and agentic AI services (Python, LangGraph, FastAPI), including data quality, LLM enrichment and evaluation.
 * Security and data protection. Protect candidate data and lead work towards Cyber Essentials Plus, the NHS DSP Toolkit and UK GDPR.
 * Accessibility. Make our platforms work for everyone, including mobile and assistive technology users, and meet WCAG 2.2 AA.
 * Impact reporting. Own the outcomes data our funders rely on.
 * Quality and reliability. Set up testing, staging, release, rollback and monitoring so a small team can ship safely.
 * SEO. Own how our jobs reach candidates through Google Jobs and AI/traditional search.
 * Leadership. Set engineering standards, make build/buy decisions and help hire the tech team.
 * Delivery. Turn commitments into a realistic roadmap with the COO, estimate honestly and ship effectively., * Technical exercise. A take-home task on a real slice of our systems, four hours maximum, with a short design note. AI tools are encouraged; we assess how well you use them.
 * Review interview. Walk our CEO and COO through your submission, then questions and a short live extension.
