Climate Tech Startup Scaling Real-World Carbon Removal

Up to £95,000 + Equity

C#, React, Python, Azure

Hybrid/Flexible | London Waterloo


We’re partnered with one of the most interesting climate tech startups in the UK right now, a company building software and infrastructure to help scale large-scale carbon removal and sustainability initiatives globally. The business is entering a major growth phase and is building out a high-calibre engineering team to support that growth.


They’re hiring a Senior Product Engineer / Senior Software Engineer to help build systems that sit across operational tooling, infrastructure, data-heavy workflows, and user-facing products. This is a genuinely broad engineering role with strong ownership and plenty of technical complexity.


The environment is very product and engineering-led. Engineers are trusted to make decisions, work closely with stakeholders, and own features end-to-end from design through to deployment and production maintenance. It’s a strong opportunity for a Senior Software Engineer who enjoys autonomy, systems thinking, and solving real-world problems at scale.


They’re especially interested in engineers who:

  • Enjoy solving complex real-world problems
  • Think pragmatically about architecture and trade-offs
  • Are comfortable working across multiple parts of a platform
  • Have experience with data-intensive systems or distributed/event-driven architectures
  • Use AI tooling heavily but thoughtfully within their development workflow
  • Thrive within fast-moving startup environments


Tech stack includes:

  • C#
  • React
  • Python
  • Azure
  • Event-driven systems and cloud infrastructure


Why it’s interesting:

  • Mission-driven engineering with real-world impact
  • Complex technical challenges beyond standard SaaS products
  • Strong engineering autonomy and ownership
  • Opportunity to influence architecture and engineering culture early
  • Equity alongside competitive salary package


If this sounds like something you’d like to explore further, feel free to apply or reach out directly for more context.
