More

We are an early-stage AI start-up building large-scale operational AI systems that automate highly complex enterprise workflows. Our platform is AI-native and focused on autonomous workflows, reasoning systems, orchestration, and large-scale document and case processing in highly regulated environments. We are already live with enterprise customers and are now entering a major scaling phase as demand and customer onboarding accelerate. This is a remote-first role across the UK, offering significant technical influence, high ownership, and the chance to help shape the next evolution of our platform. We are a small, highly capable engineering team operating in a modern, product-focused environment with strong use of AI-assisted engineering workflows, and there is a genuine pathway into broader engineering leadership as we grow.
