I'm working with a fast-growing climate-tech non-profit tackling one of the most important infrastructure challenges in the energy transition. Backed by some of the biggest names in climate philanthropy, this is an organisation doing real work - not reports, not consultancy, actual software that shapes energy investment decisions globally.
They're hiring a Lead Backend Engineer to lead a small squad, own the technical direction and get stuck into some genuinely interesting engineering. Think computational complexity, mathematical optimisation, and performance challenges at scale - a long way from your average API job.
Requirements:- 7+ years experience developing and maintaining scalable Python/FastAPI back-end services
- Ideally worked with high-performance APIs for complex hierarchical data queries and grid modelling computations
- Managed and optimised GCP cloud infrastructure, implementing CI/CD pipelines and infrastructure-as-code
- Lead technical planning by breaking down roadmap items into scoped engineering work, driving ADRs and setting standards for code quality, testing, and API design
- Collaborate cross-functionally with front-end, data engineering, modelling and product teams to deliver reliable, impactful features
- Line-manage a team of 3–5 engineers through 1:1s, career development, performance reviews, and acting as the first escalation point for technical blockers
