We are a profitable and ambitious scale-up, with several full-time, on-site openings in our technical team to underpin our rapid growth.
What You’ll Do
- Solve real-world energy problems, often requiring novel approaches developed through team collaboration and original research.

- Continually improve our shared libraries and workflows to ensure they are fast, accurate and a delight to use.
- Become a trusted expert in the topics you work most deeply on.
This position blends software engineering (performance, algorithmic optimisation, well structured code developed in an iterative fashion) with data science (analysis, identifying patterns in data and model development)
Why Volcore?
- Uncapped career development: Deliver value, and you’ll be recognised and rewarded, regardless of title or experience. We offer continuous opportunities for growth and new challenges.

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).
- Completion of at least one challenging software project in a compiled, lower-level language (ideally Rust, but open to others)
- 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.
Starting salary: £34,000 + participation in our bonus scheme for high-performers.
