Staff Software Engineer / Python / TypeScript / LLMs / AI Agents / Cloud

Staff Software Engineer

Location: London (Old Street, 5 days onsite)

Job Title: Staff Software Engineer

About the role:

We're on the lookout for an exceptional Staff Software Engineer to join one of London's fastest-growing AI startups building autonomous AI voice agents that are redefining how businesses interact with their customers.

This is a unique opportunity to build production AI systems powered by the latest Large Language Models, designing intelligent agents capable of handling complex customer conversations, reasoning through problems, and autonomously completing real-world tasks. You'll work at the cutting edge of applied AI, helping shape products where LLMs aren't simply an added feature—they're the core of the user experience.

As a senior member of the engineering team, you'll own products end-to‑end, partnering directly with customers to understand their workflows before designing and shipping AI-native solutions that solve genuine operational challenges. You'll be building highly reliable, scalable systems that combine LLMs, voice technologies, event-driven architectures and cloud infrastructure to create seamless, autonomous customer experiences.

Joining at this stage means becoming one of the senior technical leaders in a well-funded, high-growth startup. You'll have significant ownership over technical direction, influence product strategy alongside the founders, and help define engineering best practices as the company scales.
