Junior Data Scientist / Mathematical Model Developer

At Volcore, our team of wholesale electricity traders and technical experts work together to make real-time decisions that support increasing renewable generation and keep the electricity system stable. We are a profitable and ambitious scale-up, with several full-time, on-site openings in our technical team to underpin our rapid growth.

• 
  
• Solve real-world energy problems, often requiring novel approaches developed through team collaboration and original research.
  
• Identify and ingest relevant data, ensuring thorough documentation in our internal knowledge base.
  
• Iteratively test hypotheses and develop proof-of-concepts to solve real-time forecasting problems.
  
• Document and visualise results, sharing insights with the team.
  
• Develop, deploy and maintain our software with a focus on speed and accuracy.
  
• 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 data science with the software engineering skills needed to make performant, real-time models.

• 
  
• 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.
  
• Fast-growing scale-up: We’re a profitable, ambitious company on a rapid growth trajectory, giving you the opportunity to 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.
  
• Modern tech stack: Including Python, Node JS / Typescript, PostgreSQL, DuckDB and Rust.
  
• 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.
  

• 
  
• 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.
  

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