Founding Software Engineer - Climate Tech Platform
? Founding Software Engineer – Product & Platform | GreenTech
? UK-based | Remote-first
? £70-100k
Want to build technology that has a visible impact on the world around us?
We're working with a growing green-tech company using science, data and software to help make cities and land greener. They're looking for a Senior Software Engineer to take ownership of their platform end-to-end.
This is a genuine founding engineering role. You'll work directly with the CEO and a Senior Data Scientist, shaping the architecture, roadmap and product rather than simply maintaining someone else's.
? What you'll own
- Build and ship features for site analysis and planting design
- Own the platform across security, reliability and usability
- Harden and launch the existing AWS environment
- Own infrastructure-as-code and the deployment pipeline
- Build proper alerting, observability and disaster-recovery processes
- Improve performance, accessibility and overall product polish
- Develop multi-tenant SaaS capabilities
- Work directly with users and the CEO to turn real requirements into product features
? What we're looking for
- Strong TypeScript across Node.js and modern React
- Solid AWS + Infrastructure as Code experience
- Strong understanding of application security — authentication, sessions, secrets, TLS, headers, WAF and IAM
- Experience running production services: CI/CD, containers, observability and safe migrations
- Test-first mindset and a preference for clean, reviewable changes
- Strong product mindset with experience shipping user-facing features
⭐ Nice to have
- tRPC, Drizzle or WorkOS/Auth0/Clerk/Cognito
- PostGIS or geospatial experience
- Multi-tenant SaaS
- Experience selling technology into UK public sector or enterprise
If you're a Senior Engineer who wants real ownership, technical influence and the chance to build something with a genuine environmental impact, apply to be considered!
