📍 Hybrid, Central London (1 day/week)

💵 £120,000-140,000 + equity

💻 Python, TypeScript, LLM workflows, Fullstack

📈 AI SaaS platform – live with major enterprise clients

⚙️ Small, high-calibre engineering team – real ownership, AI-native product building

We're partnered with a fast-growing AI startup on a mission to help large organisations harness AI at scale. Their platform is already live with major enterprise clients across professional services, government and tech – and they're scaling quickly off the back of a recent Seed round backed by some of the UK's top investors.

They’re now looking to hire an experienced IC in the shape of a Staff Software Engineer to work across team. This is likely to be someone who can demonstrate a breadth and depth of experience across the fullstack within AI enabled environments. This is a hands on role building AI-powered products and chaining LLM-driven processes into production workflows.

The engineering team is small, sharp, and highly product-focused. Engineers work with real ownership and move quickly, with the chance to shape how AI systems are designed and deployed across the platform. The environment is genuinely AI-native, with strong internal adoption of AI tooling and a high bar for practical fluency.

You’ll be joining at an exciting point in the company’s growth: the product is already proven in market, but there’s still lots of room to influence architecture, workflow design, and how AI capabilities are embedded into the product over time.

Ideal profile:

• Strong Fullstack engineering background, ideally using Python, TypeScript and Reactjs/Vuejs - However the exact tech stack is not important, a generalist would do well in this role.
• Experience building AI native products or AI-powered internal tools in production
• Comfortable designing reliable backend systems around AI use cases, not just basic API integrations
• Able to work in a product-minded way, translating AI capability into practical features and business value
