Senior AI Engineer | Hybrid (3 days/week in London) | Up to £140k + Strong Equity Package | Node.js + React + AI-Native Engineering
We’re partnering with a fast-growing, technology-led startup building AI-enhanced consumer experiences at scale. Their platform powers a multi-brand ecosystem across commerce, operations, and data infrastructure, underpinned by proprietary technology and automation.
As they scale, they’re looking for a Senior AI Engineer to join a high-impact product engineering team. AI-assisted development is deeply embedded into how they operate- from agentic coding workflows and autonomous tooling to rapid prototyping, testing, and deployment. They see modern AI tooling as a force multiplier for exceptional engineers.
This is a hybrid role in London.
