Are you a methodical graduate who enjoys the “detective work” behind real-world data? This position goes beyond building pipelines – you’ll work hands-on with the complex, messy data that underpins UK energy markets, trading, and grid analytics. This is a rare opportunity to develop deep expertise in GB balancing market data using a modern data stack (Python, dbt, PostgreSQL, GitHub Actions), with no legacy Excel workflows.
The RoleAs a Junior Data Specialist, you will:
- Perform data detective work: Investigate, map, and clean complex energy datasets — for example, cross-referencing Elexon API data with manual research to correctly link power plants and substations.
- Wrangle real-world data: Reconcile legacy data formats, manage time-series outliers, and resolve inconsistencies across different energy market message types.
- Build and automate: Write Python scripts to ingest data from National Grid ESO and Elexon APIs, using dbt and SQL to implement transformation logic.
- Document critical insights: Maintain reference datasets and clearly document mappings, assumptions, and edge cases that support trading and operational decisions.
- Education: A recent graduate in a quantitative discipline such as Computer Science, Physics, Mathematics, Engineering, or Economics.
- Python skills: Strong foundations in Python, with the ability to write clean, readable code using pandas and numpy.
- Data fundamentals: Comfortable using SQL to query and transform data, with a sharp eye for identifying when data doesn’t look right.
- The right mindset: Patient with ambiguity, methodical in approach, and genuinely interested in energy markets or sustainability.
Please note: this is an investigation-heavy role. It’s not suited to those who expect perfectly clean datasets or want to focus purely on cloud infrastructure or DevOps.
Why Join Us?- Meaningful impact: Work on data that directly influences how the UK power grid is balanced.
- Hybrid working: A collaborative environment with regular time in our London office (4 days per week).
- Develop rare expertise: Build highly valuable knowledge of the UK’s complex energy infrastructure.
- Modern data stack: A reproducible, scalable environment built with modern tools and best practices.
