Volcore | Manchester, UK | ONSITE | Full-Time | Software Engineer

At Volcore, we model the electricity system to do proprietary trading that helps balance the grid and facilitate renewables integration. Our technical roles are a blend of Software Engineering and Data Science, wherein we solve problems end-to-end, from data ingestion and analysis to optimisation and deployment. Often these require novel solutions, drawing on original research and experimentation. We are a profitable and ambitious startup looking for Software Engineers who can both crack these kinds of problems and continually improve our shared libraries, tooling and workflows to ensure they are fast, accurate and a delight to work with.

Our team are close-knit, with minimal hierarchy and almost zero meetings. We work together in-office to whiteboard solutions together and everything we build is used by people sitting next to us.

Typically these positions attract people who have outgrown their previous role and are seeking more responsibility or more challenging subject matter. Every team member owns important projects very early on, and if you can deliver value in a particular area, you’ll be recognised and rewarded for it, regardless of job title.

Our tech stack includes Python, backend Typescript, Postgres and, increasingly, Rust, although the latter is not a Day-1 requirement.

We review all applications personally. For more info, including our requirements and salaries:
