This role suits someone who enjoys ownership, shipping real product, and making pragmatic decisions in fast-moving environments.

The role

You will take responsibility for delivering key product areas end-to-end, from technical design through to release and iteration. Early on, youll be relied upon to write and ship critical parts of the system yourself while helping establish strong engineering foundations.

This is not a role focused on meetings, ticket administration, or status reporting. Delivery and quality come first.

• Making sound technical trade-offs across frontend, backend, and data workflows
• Driving improvements in platform foundations including performance, observability, security, and cost awareness
• Establishing lightweight delivery cadence with clear definitions of done and reliable releases
• Collaborating closely with product managers, designers, and senior stakeholders

What were looking for

• 710+ years experience building and shipping production software in product-led environments

• Strong full-stack engineering fundamentals, including:

  • TypeScript / Node.js backend systems
  • React + TypeScript on the frontend
  • PostgreSQL and data modelling (geospatial or mapping experience a bonus)

• Proven experience owning projects end-to-end and shipping to production repeatedly

• Experience building data-heavy B2B SaaS products (dashboards, workflows, permissions, internal tooling)

• Strong product mindset with a high bar for usability, accessibility, and UI quality

• Comfortable working with incomplete requirements and turning ambiguity into delivery

• Experience leading or mentoring small engineering teams

• A builder-leader mindset: able to write high-quality code while raising the bar for others

Nice to have

• Experience in high-integrity data environments (e.g. compliance, reporting, analytics platforms)
• Experience setting up early-stage engineering foundations (CI/CD, environments, logging/metrics)

Role details

• Full-time, permanent position
• Remote working (UK or European time zones)
• £95,000 per annum
• Equity participation available
• Opportunity to play a key technical leadership role as the platform and team scale
