Senior Back-end Software Engineer (TypeScript)
Salary: up to £85,000 
Location: Fully remote (UK, EU, or North America time zones)

We’re hiring a Senior Back-end Software Engineer to join a fast-growing startup in the sustainability and renewables space.

The business is scaling its customer and internal platforms and is building out the core backend and data foundations that underpin a growing product ecosystem. This is a hands-on role with real influence over architecture, data systems, and platform direction.

Importantly, there is a clear progression path in mind towards a Head of Software Engineering position as the engineering team grows. This role is well suited to someone who wants to remain technically hands-on while gradually taking on broader ownership and leadership responsibility.

The role

• Design, build and extend backend systems using TypeScript and modern serverless patterns

• Develop and maintain APIs and integrations that power customer-facing and internal platforms

• Work with database schemas, authentication, and backend services to support scalable data pipelines

• Collaborate closely with frontend engineers to deliver end-to-end features

• Contribute to internal automation tools and operational workflows

• Balance rapid delivery with reliability, performance and maintainable system design

About you

• 5+ years’ professional experience in backend or full-stack engineering

• Strong proficiency in TypeScript in production environments

• Solid understanding of API design, database modelling and serverless architectures

• Comfortable working across backend logic, data modelling and platform integrations

• Experience working autonomously in remote, distributed teams

Nice to have

• Experience with Supabase or similar backend-as-a-service platforms

• Exposure to data pipelines, analytics or AI/ML integrations

• Familiarity with geospatial, sustainability or data-intensive systems

What’s on offer

• Salary up to £85,000

• Fully remote, long-term role

• High-impact position in a scaling, mission-driven startup

• Clear progression towards Head of Software Engineering

• Opportunity to shape the technical foundations of a growing platform

If you’re a senior backend engineer looking for a role that combines hands-on technical ownership with a clear leadership trajectory, this is a strong opportunity.
