Lead Site Reliability Engineer in London

About Artificial

We are building the next generation of technology for the specialty (re)insurance market. Our mission is to transform how brokers and carriers operate in complex markets by removing operational barriers and enabling smarter, faster decision-making. We use modern technology to solve real challenges for some of the world’s leading brokers and insurers. By automating the repetitive and structuring the complex, we help our partners unlock new opportunities for innovation and growth.

You’ll be joining a collaborative team that values curiosity, ownership, and continuous learning. We work in an environment where ideas are heard, support is built-in, and outcomes matter. Everyone here has the chance to make a tangible impact on our products, our customers, and the industry.

We’ve just raised $45M (£33M) in Series B funding from lead investor CommerzVentures, new investor Move Capital, as well as all existing shareholders. This investment round gives us the room to grow with confidence, continue to innovate, and ensure that Artificial remains the first choice for brokers and carriers seeking a smarter way to trade digitally.

Our values

• Build high-quality, robust features and supporting infrastructure that sets the standard for the rest of the engineering team
• Ask good questions, share knowledge, mentor and develop others in the team
• Continuously improve operations (think: Kaizen, Toyota Way)
• Spread skills across the team, discouraging knowledge silos
• Have the confidence needed to be ambitious and do what others can’t

You’ll be working with talented people, using the latest technology in an environment that supports learning. As an outcomes-focused business, taking ownership is not only expected but embraced, meaning the opportunity to create meaningful change is within your power.

• Make informed decisions on libraries, abstractions, and tooling, clearly communicating trade-offs.
• Develop and operate performant Haskell services, applying appropriate data structures and testing strategies.
• Drive system reliability, observability, and incident response, working hands-on with infrastructure and operations.
• Communicate complex technical and organisational topics clearly, creating alignment across teams and stakeholders.
• Mentor and support engineers, improving team processes, wellbeing, and long-term organisational effectiveness.

About You
