Job Specifications

Are you a Senior Frontend Engineer who wants to build products that actually help fight climate change, and use the latest AI tools?

Techmunity are hiring on behalf of a well-funded Series A startup at the intersection of green finance, emissions reduction, and live data platforms.

Backed by global investment firms and major names in green energy and transport, they’ve just signed a major financial institution and are expanding across the Middle East and US.

You’ll join a tight-knit dev team (currently 3) and will be given end-to-end ownership of a complex, high-impact frontend codebase - under the mentorship of a CTO who's published several software architecture books and is an AI keynote speaker, who's willing to upskill you in this area!

As a Senior Frontend Developer you will:

Take charge of a large React + TypeScript codebase (500k+ lines of code)
Handle live data portals built around event-driven architecture, reducing flicker and fighting re-renders
Refine test coverage and bring structure to a codebase that needs modernization
Work on innovative features like pollution/heat mapping, hydrogen asset monitoring, and financial tools
Build intuitive, performant visualizations of complex financial data

You’ll Need:

5+ years in modern frontend engineering, ideally coming from a senior or lead role
Strong in React + TypeScript, ideally with experience in event-driven UIs (WebSockets, real-time feeds)
Comfortable working on financial dashboards, charts, or statistical tooling
Excited to learn or use AI tools like GitHub CoPilot and CodeRabbit (used daily here)

Depending on whether you're coming from a Senior or Lead background, they are paying £80,000–£110,000, plus benefits like share options, private medical, life insurance and much more!

The team meets up Monday, Wednesday and Thursday in their Central London offices.
