Role overview
Software for Subcontractors.
From small surveys to multi-site mega projects, Onetrace provides full visibility across construction projects. We help our clients stay in control, make informed decisions, and grow a stronger, more profitable business.
Over a thousand of the leading subcontractors trust Onetrace to deliver higher quality work and optimise their workforce, increasing profitability and client trust.
Building great technology takes more than knowing construction. It takes knowing code, systems, scalability, security, and support. That’s what Onetrace does.
What you will do
- Own the end-to-end development of new features, handling everything from UI and application logic to database layers, observability, and automated testing strategies.
- Partner directly with product managers, designers, and customers to understand user pain points and translate them into high-impact technical solutions that work in the field.
- Mentor other engineers and raise the technical bar by implementing best practices in RESTful API design, CI/CD pipelines, and modern engineering workflows using AI tools.
Who this is a fit for
- Proven experience with JavaScript/TypeScript and Node.js, with the ability to navigate both MongoDB and SQL database environments effectively to build scalable B2B SaaS products.
- Strong background in building distributed systems and modern DevOps practices including AWS, Terraform, message queues, and automated monitoring/observability tools.
- Product-minded engineer who values user impact over just writing code, ideally with experience in growth-stage startups and a desire to work in a hybrid Canary Wharf office.
Why this role is remarkable
- Work for a profitable, bootstrapped company that is one of the fastest-growing players in the UK construction sector without the volatility of traditional venture funding cycles.
- Solve high-stakes real-world problems by building software that ensures building safety and compliance, directly impacting the lives and safety of people in buildings across the country.
- Join a high-autonomy environment where you own features from conception to deployment and help shape the engineering culture and technical standards within a growing team.
