They're building an AI adoption platform that helps organisations move beyond AI experimentation and actually embed AI into how their teams work. The product helps businesses understand where AI can genuinely improve workflows, build confidence across teams and measure meaningful adoption, rather than simply giving people access to another AI tool. They've already achieved: * Strong product-market validation with a growing user base and enterprise customers * Backing from leading UK technology investors * A proven platform with significant commercial traction * Expansion into international markets For a mid-level or early Senior Product Engineer, this is an opportunity to join at a stage where the product is already validated, but the engineering team is still small enough that you can have genuine influence and continue to grow. The team already has a strong senior engineering foundation in place, so these hires are about adding the next generation of engineers and creating room for progression. What could you be building? The engineering challenges are varied and constantly evolving: * Building reliable AI-powered product experiences that help users adopt and get value from AI * Designing and improving AI workflows, including evaluation, monitoring, tracing and iteration * Developing personalisation and recommendation systems using individual, team and organisational context * Solving complex data modelling, permissions and privacy challenges as enterprise adoption grows * Improving platform architecture, reliability and performance as the user base scales * Exploring emerging AI capabilities and deciding what creates genuine customer value versus what is simply hype What makes this Product Engineer role different? You'll have ownership across the full product lifecycle. As a Product Engineer / Software Engineer, you'll be involved in: * Understanding customer problems and shaping what should be built * Working closely with Product and Design to create intuitive user experiences * Making pragmatic technical decisions across frontend, backend, APIs and data * Building and shipping customer-facing features that directly impact users * Improving engineering standards and ways of working as the team grows * Using AI-native development practices to increase delivery speed without compromising quality The team is particularly interested in strong up-and-coming engineers, rather than only hiring people who already have years of Senior-level experience. They're looking for someone who is proactive, curious and comfortable learning quickly. Motivation, growth potential and evidence of self-learning are particularly important.
