London Hybrid (2 days in the office) £100,000 - £120,000 + Equity

Build the Future of AI Automation

We are partnered with one of London’s most exciting AI startups, recently backed by $13 million in funding, as they scale both their product and engineering team. Their mission is simple but ambitious: make it possible for anyone to build powerful AI-powered automations through conversation, without writing code. Already trusted by global businesses, they are now entering an exciting new stage of growth and are looking for a Senior AI Product Engineer to help shape what comes next. This is a rare opportunity to work directly with the founders, influence technical direction, and build AI products that solve real customer problems.

The Role

This is a hands-on engineering role where you will help scale both the product and the engineering function. You will develop new platform features, improve the intelligence behind their AI assistant, and help establish the engineering practices needed to support rapid growth. You will work across product, AI and engineering, taking ownership of technical decisions while remaining deeply involved in building. If you enjoy solving difficult problems, moving quickly and having genuine influence over the products you build, you will thrive here.

What You’ll Be Doing

• Design, build and ship new product features.
• Improve the performance, accuracy and capabilities of the company’s AI-powered platform.
• Prototype and deliver new AI-driven functionality.
• Work closely with the founders to turn ideas into production-ready solutions.
• Help shape engineering processes, standards and best practices as the team grows.
• Take ownership of key parts of the platform and contribute to technical direction.
• Balance fast delivery with high-quality engineering.

What They’re Looking For

You will probably have experience in a startup or scale-up environment where you have helped take a product through significant growth. Ideally you will have:

• Excellent Python development experience.
• Strong JavaScript or TypeScript skills.
• Experience building AI-powered products using modern LLMs.
• A proven track record of shipping high-quality production software.
• Experience working closely with product teams and founders.
• The confidence to take ownership and make technical decisions.
• Strong communication skills and a collaborative approach.

Experience helping to establish engineering processes or supporting a growing engineering team would be a significant advantage.

Why Join?

• Join a well-funded AI company entering its next phase of growth.
• Work directly with experienced founders building cutting-edge AI products.
• Build with the latest AI technologies and frontier models.
• Enjoy real ownership and influence over both product and engineering decisions.
• Competitive salary plus meaningful equity.
• Hybrid working from a modern Central London office.
• High-performance, collaborative engineering culture with regular hackathons, conferences and professional development support.

If you are excited by building exceptional AI products, solving challenging engineering problems and helping shape the future of intelligent automation, we would love to hear from you.
