About the Role
ELMI AI is building a software platform to intelligently control charging stations and battery storage systems. This platform will read and process data from energy management systems, analyze competitor pricing, dynamically adjust its own pricing, optimize battery recharge strategies, and engage in active energy trading. We are looking for an experienced Software Engineer with architectural expertise to help build this robust, production-ready software product from its early stages.

- Technically implement interfaces and trading logic for automated energy trading.
- Collaborate closely with the development team (including nearshore team), including code reviews and participation in technology decisions.
- Actively develop code, especially during the critical build-up phase of the first stable version.
Requirements
- Several years of experience as a Software Engineer, ideally with experience building a software product from an early phase.
