Reporting to: Director of Product Engineering

About the role

We're looking for a Product Engineer to translate complex user needs into elegant, high-impact solutions. You will contribute to building and maintaining features across our stack. You’ll collaborate closely with Senior Product Engineers on design and architecture decisions, write clean and efficient code, and help ensure best practices are followed throughout the development process.

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

What you'll bring

Essential

• JavaScript / TypeScript – core programming languages
• Node.js – primary backend framework
• API design and implementation
• Git – version control and collaborative workflows
• Testing strategies (unit, integration, end-to-end)
• Experience with monitoring, logging, and observability tools
• Familiarity with modern AI tools and a habit of staying up to date with how they can improve engineering workflows

Highly Desirable

• AWS infrastructure and services
• MongoDB or other NoSQL database
• SQL databases and query optimisation
• CI/CD pipelines and DevOps practices

Nice to Have

• AdonisJS, NestJS or similar MVC frameworks
• Distributed systems experience
• Message queues and background job processing
• Caching strategies and performance optimisation
• Security best-practices implementation
• Experience in a growth-stage startup or B2B SaaS
• Knowledge of the construction industry
• Infrastructure as Code (Terraform or similar)

What we offer

• 25 days PTO, plus bank holidays
• Enhanced parental leave
• Private medical insurance with Bupa
• NEST pension scheme
• Employee assistance programme
• Remote work abroad opportunities
• Apple MacBook and tech accessories
• Onetrace merch, regular team socials and annual company offsites

Hybrid guidelines

We operate a hybrid working model, with a minimum expectation of 2-3 days per week in the office. This is a core part of how the role works and isn’t something we’re flexible on.
