- Mentor and coach other engineers while championing technical excellence through rigorous code reviews, observability practices, and modern CI/CD workflows.
Who this is a fit for
- Extensive experience building full-stack applications with Node.js and TypeScript, demonstrating a strong ownership of features from concept through to deployment.
- Proficient in managing complex data flows using MongoDB and SQL databases, with a keen eye for query optimization and scalable system design.
- Strong product mindset with a desire to talk to users, understand their challenges, and apply technical creativity to build impactful B2B SaaS solutions.
Why this role is remarkable
- Impactful Work: Your code directly improves building safety standards across the UK, providing critical traceability and compliance for major infrastructure projects.
- High Autonomy: As a Product Engineer, you aren’t just taking tickets; you’ll partner with founders and designers to define the ‘why’ behind every feature.
