Hg Catalyst is the AI product incubator for Hg, one of Europe's leading software investors with $100B+ under management. We're not consultants or advisors - we're builders.
We embed inside some of the world's leading software companies to build the agentic products that millions of people rely on to do their jobs. The industries we work in have fractal complexity: layers of rules, exceptions, and edge cases that compound the deeper you go. Accuracy is non-negotiable. We build production-grade AI that consistently delivers for the people who depend on it.
Catalyst is a team of engineers, product leaders, and designers. We operate from London and New York and have shipped 30+ products across complex, regulated industries including tax, accounting, legal, compliance, financial services, payroll, and healthcare.
The Role: Applied AI Engineer
We're looking for Applied AI Engineers who can work at the intersection of AI and real-world business problems. This isn't about building demos. You will own end-to-end development of production AI systems serving real customers from day one.
What You'll Do
Own the full stack and product lifecycle
Make AI work where it's hardest
Build across multiple products and industries
Work alongside experienced operators
Who You Are
Technical depth
Execution speed
Product sense
Mindset
Why Catalyst
Build multiple products, not just one: Most engineers get one shot at a startup. Here, you're a serial AI product builder, launching across industries in 9–18 month sprints. Each success becomes a case study, each failure a rapid lesson.
Tackle hard problems: We work in complex, regulated industries where AI solutions must function as designed, accurately. Production systems serving real customers from day one.
Learn from the best: Work directly with the leadership of $100M+ companies, exited founders, engineers from frontier AI labs like Anthropic and OpenAI, and Hg's network of software operators across the Atlantic. Compress a decade of enterprise AI learning into two years.
Ship with velocity: Build like a startup, with enterprise scale. You own the full product lifecycle with the autonomy of a founding team and the resources of established businesses.
