Founding Full Stack Developer

New Today

Founding Full Stack Developer | GreenTech Start-up | £65k

I'm working with an early-stage UK GreenTech start-up building software that supports sustainability-focused, real-world systems, not consumer apps or vanity features.

This is a genuinely early engineering hire into a small, ambitious team where engineering decisions directly influence how the business operates and scales. If you enjoy start-up environments with autonomy, responsibility, and visible impact, this role is a strong fit.

The opportunity

They're looking for a hands-on Full Stack Developer to take ownership of an existing platform and help shape the next phase of development.

In the short term, you'll:

Own and evolve a live TypeScript-based system used daily by the business

Work closely with founders and stakeholders to stabilise and improve core functionality

As the platform matures, you'll:

Lead greenfield development of new internal tools

Build systems focused on data capture, operational insight, and reporting

Influence architecture, tooling, and technical direction as the engineering function grows

Help shape software that supports sustainability-driven outcomes

This is very much a start-up role - ambiguity, ownership, and learning are part of the job.

Tech environment

TypeScript (full stack)

MongoDB

Product-led, start-up engineering environment

Strong emphasis on reliability, data, and maintainability

What they're looking for

A Full Stack Engineer comfortable working end-to-end

Someone who enjoys early-stage start-ups and taking ownership

Experience maintaining live systems as well as building new functionality

Product-minded, pragmatic, and able to see the bigger picture

Clear communicator, comfortable working with non-technical stakeholders

Location & working pattern

UK-based

Flexible across London, Manchester, or Edinburgh

Preference for 3 to 4 days onsite, with flexibility for the right candidate

Salary

Circa £65,000, with some flexibility depending on experience

Why this role?

Join early in a mission-led GreenTech business

High ownership and influence over product and engineering decisions

Blend of stability (existing systems) and greenfield development

Opportunity to grow alongside the company as it scales

Build software that contributes to meaningful sustainability outcomes

If you're a Full Stack Engineer looking for a proper start-up role in GreenTech.

With autonomy, ownership, and room to grow: this is well worth exploring.
