Staff Product Engineer (Remote) (up to £160k)

Most AI applications in the public sector are either slide decks or low-impact pilots. This company has over 120,000 frontline workers across hundreds of organisations actively relying on their AI platform to handle calls, automate notes, and run live translation in real time. Backed by the founders of some of the world’s most successful consumer tech companies and growing rapidly, they are proving that AI can solve the administrative crisis in essential public services at genuine production scale.

As a Staff Product Engineer, you will set technical direction across multiple teams and architect the systems that allow the platform to scale globally. This is not an isolated architecture seat where you produce RFCs from an ivory tower, nor is it a feature-factory ticket-taker role. You will bridge product strategy and deep engineering, shipping production code to more than 100,000 users multiple times a day while setting the standard for how AI reshapes internal engineering workflows.

The work

• Set technical and architectural direction across product engineering, balancing rapid iteration against the reliability required by frontline public services.
• Architect and evolve systems supporting live interpretation, audio pipelines, and workflow automation for over 100,000 daily active users.
• Ship to production multiple times a day across a modern stack spanning Ruby on Rails, TypeScript, PostgreSQL, GCP, and React.
• Integrate cutting-edge AI capabilities directly into core product features and internal engineering tooling to accelerate delivery.
• Take end-to-end ownership across infrastructure, data, and user interfaces, proactively resolving bottlenecks before scale breaks them.

• Proven track record operating at Staff or Principal level, driving technical strategy and system architecture across multiple product teams.
• Full-stack breadth across backend, infrastructure, data, and frontend, with demonstrated experience evolving production systems for substantial scale.
• A rigorous product mindset: you evaluate technical decisions by user outcomes and real-world utility, not architectural purity.
• Comfort working with or adopting a modern web stack centered on Ruby on Rails, TypeScript, PostgreSQL, and React.
• Hands-on experience leveraging AI tools to accelerate software development and build production workflows.
