Job description

About Us // About Hg Catalyst Labs

Catalyst Labs 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 operate as a serial AI product factory embedded directly into Hg's portfolio companies, conceiving, building, and shipping AI products that generate real revenue and serve millions of users. Our unique model: launching transformative products for B2B SaaS or services companies in 9-18 month sprints, with each product built into an established business with existing customers, infrastructure, and go-to-market capabilities.

We eliminate typical startup risks while maintaining the pace and ownership of a founding team. When you join Catalyst Labs, you become a serial AI product entrepreneur with the support of one of the world's premier software investors.

The Role: AI Product Engineer

We\'re seeking exceptional AI Product Engineers who can operate at the intersection of cutting-edge AI technology and real-world business impact. This isn\'t about building demos or proofs-of-concept. You will own end-to-end development of production AI systems serving actual customers at scale from day one.

Who You Are

Technical Excellence

• Strong engineering fundamentals with 5+ years building AI production systems

• Comfortable with infrastructure (K8s, cloud platforms), backend (Python, FASTapi) and front-end (React, TypeScript)

• Hands-on experience with modern AI/ML frameworks and deployment patterns, including GenAI

• Track record of shipping products that scale to thousands of users

Execution Velocity

• Demonstrated ability to ship fast without sacrificing quality

• Experience in high-growth startups or equally fast-paced environments

• Comfortable with ambiguity and rapid iteration

• Strong opinions, loosely held: able to make decisions with incomplete information

Product & Business Acumen

• Intuition for what makes products valuable to users

• Ability to translate between technical complexity and business value

• Experience working directly with customers and stakeholders

• Understanding of enterprise software dynamics is a plus

Mindset & Drive

• Enthusiasm about AI – from the products we are building, to the latest tools, and AI-first ways of working

• Hunger to build products that matter, not just interesting technology

• Ownership mentality: you don\'t wait for specifications, you create them

• Intellectual curiosity across industries and technologies

• Thrives in intense, high-performance environments

• Ready to work hard and learn fast
