## About the Role

* 5+ years of professional software engineering experience, with a significant part on embedded Linux, edge or industrial systems.
 * Strong skills in C++, Go or Rust, plus Python for tooling, testing and data analysis.
 * Hands-on experience with industrial and fieldbus protocols, ideally CAN and Modbus.
 * Experience building reliable data acquisition pipelines and software that runs unattended in the field.
 * Comfortable working close to hardware: reading datasheets and schematics, and using an oscilloscope, CAN analyser or logic analyser to find the root cause of a problem.
 * A systems mindset and good judgement about safety, robustness and failure modes.
 * Willingness to work hands-on at our test site and, occasionally, at customer sites.
 * Fluent English.

Nice to have:

 * A background in electrical engineering is a strong plus.
 * Experience with battery storage, solar PV, inverters or other power electronics.
 * Familiarity with real-time Linux, Yocto or similar embedded build systems.
 * Experience with grid communication protocols such as IEC 61850, SunSpec or DNP3.
 * Experience with cloud connectivity for devices, such as MQTT.

## Description

* Design, build and own the production site controller software, from architecture to deployment and long-term maintenance.
 * Build robust data acquisition and processing: reliable, time-stamped collection of measurements and events from the BMS, power converters and inverters, with local storage, buffering and forwarding to the cloud.
 * Implement low-level communication and control over Controller Area Network (CAN), Modbus TCP and Modbus RTU, including device drivers, protocol handling, state machines, sequencing and safe fault handling.
 * Build commissioning and diagnostic interfaces into the site controller, so field engineers can bring a site up, configure it and troubleshoot it quickly. Where needed, extend these to customer-facing interfaces, both to the customer's supervisory control and data acquisition (SCADA) system and directly to users.
 * Run integration and validation work on our test setup: write test scripts and tooling, analyse data and turn findings into fixes and requirements.
 * Define the interfaces between the site controller, BMS firmware and cloud platform, together with the relevant engineers.
 * Help lay the foundation for later energy management and dispatch features.
 * Set good engineering practice for edge software: version control, code review, automated testing, continuous integration and controlled releases.
