Job description

I'm working with a Climate Tech startup that’s fresh off a £5m seed round and already pulling in £3m ARR—and they’re only getting started. They’re tackling some of the biggest environmental challenges out there, and they need a Senior Software Engineer who’s excited to build solutions that make a tangible difference. If that sounds like you, keep reading.

What You’ll Do

• Architect & Build: You’ll design and implement features from the ground up on their climate-focused platform—turning big ideas into robust, scalable solutions.
• Solve Complex Problems: This is no ordinary environment; you’ll wrestle with scale, data integrity, and the unique challenges of a climate-related product.
• Collaborate: You’ll work cross-functionally with product, design, and other engineers to shape the roadmap and ensure top-notch user experiences.
• Own Your Work: From concept to deployment, you’ll have full responsibility for your projects and the outcomes they drive.

What They’re Looking For

• Technical Excellence: You’ve got a strong foundation in modern software development—whether it’s microservices, front-end frameworks, or data pipelines. (Their stack is Python, React, AWS)
• Passion for Impact: They’re all about real-world solutions, so if you’re excited by the prospect of using tech to make a difference, you’ll fit right in.
• Startup Vibe: This is a fast-paced environment with plenty of room for creativity, experimentation, and iteration—you’ll need to adapt quickly.
• Autonomy & Initiative: They love self-starters who spot opportunities for improvement and make them happen.
• Clear Communication: Expect daily collaboration and feedback loops—you’ll want to keep everyone in the loop and vice versa.

Why Join Them?

• Meaningful Work: Every commit directly contributes to fighting climate change—how often do you get to say that?
• Early-Stage Ownership: With £5m raised at seed and £3m ARR, it’s prime time to shape product direction, culture, and strategy.
• Fast-Paced & Dynamic: Minimal red tape, high-impact projects, and the freedom to innovate.
• Supportive Team Culture: They’re small but growing quickly, which means you’ll have a big voice in how things evolve.
• Location Flexibility: Their main office is in Farringdon, and they’d love to see you once a week if possible—but it’s not a deal-breaker if you can’t.

The Hiring Process

They keep it simple and transparent. First, there’ll be an introductory chat (with me, as your recruiter, and/or directly with them). Next up is technical deep dives—think architecture, live coding, and systems design—and finally a conversation about values and culture. No lengthy waits or hidden steps.

Interested? Drop me a message with your CV or LinkedIn, and let me know what excites you about this role. I’d love to share more details and help you explore if this could be your next big move in Climate Tech!
