Company mission
To be the leading software for subcontractors in the construction industry.
Role
Who you are
- 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
- JavaScript / TypeScript – core programming languages
- Node.js – primary backend framework
- MongoDB or other NoSQL database
- SQL databases and query optimisation
- RESTful API design and implementation
- Git – version control and collaborative workflows
- Strong experience in modern front-end development, including React, state management, modern CSS, semantic HTML, and web accessibility (a11y)
- Backend testing strategies (unit, integration, end-to-end)
- Experience with monitoring, logging, and observability tools
- Knowledge of scalable system architecture and design patterns
Desirable
- AdonisJS, NestJS or similar MVC frameworks
- AWS infrastructure and services
- Infrastructure as Code (Terraform or similar)
- Distributed systems experience
- Message queues and background job processing
- Caching strategies and performance optimisation
- CI/CD pipelines and DevOps practices
- Security best-practices implementation
- Experience in a growth-stage startup or B2B SaaS
- Knowledge of the construction industry
What the job involves
- Working here means being a product engineer, not just a backend or frontend specialist
- 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
- If you’re curious about what it’s really like to build at Onetrace, we’ve written more about our approach, straight from the people you’ll be working with:
- Our Product Engineering Culture – by Luca Carangella, Director of Product Engineering, on how we think about engineering and collaboration
- Building Products for Subcontractors – by Lewis Bird, Co-founder & CTO, on our product philosophy and the landscape we’re building for
- As a Senior Product Engineer at Onetrace, your mission is to translate complex user needs into elegant, high-impact solutions
- You will take complete ownership of features from concept to deployment, architecting and building everything from performant React frontends to scalable Node.js services
- You will help us to champion best practices, mentoring teammates, and contributing thoughtfully to the architectural decisions that shape our product's future
- 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
- 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

- At Onetrace, our team includes over 10 nationalities. We’re proud to be a multicultural, collaborative team - bringing together different voices, perspectives, and experiences to shape the future of construction technology.
- Inclusivity isn’t just part of our culture, it’s baked into our product design and customer experience. From the features we build to the way we work together, we believe great technology starts with understanding and respecting the people it’s built for.
- We believe diversity isn’t a ‘nice-to-have’ - it’s essential to building great products. The more inclusive we are as a team, the better we reflect and serve the diverse trades, people and cultures using Onetrace every day.
- Internally, we’re committed to creating a space where everyone feels they belong - where our values of respect above all and doing the right thing aren’t just words, but behaviours we live and reinforce together. Externally, that same mindset shows up in how we partner with customers - through our product, our communication and our commitment to raising the standard across the industry. Because to build technology that works for everyone, it needs to be shaped by everyone.
