Fast-growing startup: We’re a young, ambitious company on a rapid growth trajectory, giving you the opportunity to jump on board early and play a key role in shaping our future.

Impactful problem solving: You will be trusted with significant projects that can immediately, visibly affect our success and the industry more broadly, leading to innovative solutions in areas that haven’t been tackled before.

Minimal bureaucracy: Your ideas and feedback matter. We prioritise time for you to focus on what you do best, while still providing support from the wider team.

Colleagues instead of customers: Everything you build will be used by people sitting next to you.

High-performing, friendly team: Work alongside bright, driven people who are trusted to deliver and enjoy socialising after a successful day.

About You

No energy expertise required, but you must quickly learn new concepts and think independently.

Strong software development fundamentals, including optimisation of performance and implementation of complex algorithms from scratch. Ideally this should be demonstrated through passion projects or work experience beyond coursework.

Strong modelling and analysis skills using Python, SQL and backend Typescript (or two of the three and the ability to very quickly upskill with targeted support).

Excellent, practical statistical/mathematical knowledge.

The ability to document and communicate your thinking clearly, including in our knowledge base, notebooks, comments and code itself.

Ownership of projects from start to finish, with intrinsic drive to deliver high-quality work quickly.

By the time this role commences, be eligible to live and work full-time in the UK.

The following are not essential, but you will benefit from highlighting any relevant experience:

Previous longer-term employment, even where not directly related to this role, e.g. hospitality and labouring.

Software development outside of academic study, including personal projects and professional work.

Meteorological data manipulation and physical systems modelling.

Real-time and online forecasting, especially time-series.

Typically this position attracts talented programmers who are looking to prove and apply themselves at an organisation that will value and challenge them.

Salary: £34,000 + participation in our bonus scheme for high-performers.
