Senior Product Engineer

What you’ll do

• Own end-to-end delivery of features that solve real customer problems, from understanding user pain points through to shipped functionality across UI, application logic and database layers

• Build intuitive, performant interfaces that customers actually want to use—balancing user needs, accessibility, and technical constraints while ensuring features work reliably across devices and contexts

• Use customer feedback, analytics, and direct user insights to inform technical decisions, prioritise improvements, and validate that shipped features deliver measurable value

• Design and implement complex data flows, API integrations, and background processing systems that handle high-volume operations reliably while maintaining system performance and data integrity

• Partner with product, design, and customers to shape solutions early, translating business requirements into technical architecture while surfacing risks and opportunities that impact customer outcomes

• Mentor and coach other engineers, raising the bar for technical excellence through code reviews, pair programming, and architectural guidance

Beyond the tech

We are building a team of Product Engineers because we believe the most impactful work comes from those who are closest to the problems we're solving. For us, engineering is not just about executing a specification; it's about taking ownership of the user experience and the business outcome. Our engineers are partners in discovery and strategy, empowered to question assumptions, contribute to the 'why,' and use their technical creativity to build not just what is asked for, but what our users truly need.

Our engineering culture

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:

• We encourage you to talk to users and understand their real challenges

• Work as equals with product managers and designers to find the best solutions

• Care about your work from conception through production and beyond

• Balance shipping velocity with code quality and exceptional user experience

• Speak up with ideas, concerns, and feedback to help the team improve

• 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.
