Job Title: Senior Full-Stack Product Engineer

Basis: Full-time, permanent

Location: Canary Wharf, London - WeWork (Hybrid Remote)

Reporting to: Director of Product Engineering

— Great products start with great people.

Our relentless focus on user experience has been the cornerstone of our growth, helping us become the market leading software for fire protection subcontractors across the UK.

We’ve grown by staying obsessed with building software that actually works for the subcontractors on the ground; fast, intuitive, and simple to use.

We’re now gearing up for our next chapter: expanding into new trades and taking Onetrace global. We’re bootstrapped, profitable, and driven by a clear mission - to lead the digital transformation for subcontractors, one trade at a time.

Come be part of a team that’s smart, ambitious, and comfortable in the chaos of growth - where your ideas matter, and your work shapes what comes next.

We’re not your typical “move fast and break things” company. We believe in building thoughtfully and shipping quality software that genuinely helps our customers solve real problems.

Working here means being a product engineer, not just a backend or frontend specialist. We care about engineers who understand the bigger picture: the operatives on site, the project teams behind them, and the real-world impact of the tools we ship. You’ll bring curiosity to the “why” behind the work, not just the “how,” and you’ll see your code in action helping people get their jobs done with less friction.

What this means day-to-day:

• Direct customer connection - we encourage you to talk to users and understand their real challenges
• Collaborative partnership - work as equals with product managers and designers to find the best solutions
• End-to-end ownership - care about your work from conception through production and beyond
• Quality focus - balance shipping velocity with code quality and exceptional user experience
• Open communication - speak up with ideas, concerns, and feedback to help the team improve
• Continuous learning - embrace mistakes as learning opportunities and seek better approaches

We value transparency, honest communication, and engineers who genuinely care about the impact of their work. Subcontractors use Onetrace to prove their work has been carried out compliantly, with full traceability from start to finish. That not only makes their day-to-day smoother and more reliable, it also raises the standard across projects — ultimately leading to safer buildings for everyone to live and work in.

And we think that’s something worth getting excited about.
