I’m working with a genuinely purpose‑led organisation that sits right at the intersection of data, climate, and global finance. They’ve built the world’s leading environmental disclosure system, used by tens of thousands of companies, cities, and institutions to report impact and shape decision‑making. It’s a global team, but the London office is a key engineering hub, with a tight‑knit group of tech leads and platform specialists working closely together.
This role sits at a pretty interesting point in their evolution. The platform has grown quickly, and with that comes the usual integration challenges. Systems that work, but don’t always talk to each other cleanly. You’ll come in as their first Principal Engineer, reporting into the CTO, with a remit to bring clarity and structure to how services integrate, while staying hands‑on enough to influence how things are actually built. You’ll split your time between architecture and coding, working directly with tech leads across squads. A lot of the work is about making the current state legible, defining where it needs to go, and then helping teams get there without slowing delivery. There’s real ownership here, both technically and in how engineering standards evolve across the business.
What They’re Looking For:
- TypeScript
- Node.js
- React
- Nest.js
- System design (end‑to‑end platforms)
- Technical leadership (cross‑team alignment)
What You’ll Work With:
- TypeScript & Python
- Next.js
- API integrations (internal & third‑party)
Why Join?
The interesting part here isn’t just the tech, it’s the mandate. Right now, integration across services is inconsistent, with little in the way of defined contracts or shared standards. You’ll be the person who changes that. You’ll start by mapping what exists, identifying where things break down, and introducing a clear integration model that actually works in practice. Not a theoretical architecture exercise, but something squads can adopt without friction. Alongside that, you’ll be building reference implementations, shaping how APIs are designed, and improving the overall developer experience across the platform. It’s also the first role of its kind in the business. The expectation is this grows into a small group of senior engineers over time, giving you a real say in how that function evolves.
Employee Benefits:
- Generous non‑contributory pension
- Life assurance
- Employee Assistance Programme
- Training and development support
- Flexible working arrangements
- Bank holidays + standard leave
If you’ve worked in environments where integration has become messy over time and you’ve wanted the space to fix it properly, this is worth a conversation.
