Role Summary

Aubay is seeking a Backend Software Engineer to join our Global Energy client’s team and help them change the world of energy. We're looking for someone excited about green energy and software development to help tackle their reconciliation engine, a core piece of their platform strategy that ingests, curates, and exposes accurate time series data used to drive billing, trading and our data science. The data is delivered in real-time, across hundreds of data sources in minute-level blocks, compiled against different customers with different processes, and combined with the complex nature of the energy industry in the UK and abroad. Your contribution would be more than just code: our client’s team develops its architecture by consensus, so you'd be informing design decisions from day one. Our client also has a culture of mentorship across the company, so you'd be expected to help others advance your skills while having the opportunity to learn from engineers more experienced than yourself.
