The Software Engineer is a position focused on applying software development as well as providing technical guidance to other personnel involved in testing, deployment, and operation of the Eos Battery Energy Storage Systems. The Software Engineer involves collaborating with a team and individual efforts to design and maintain solutions in the effective and efficient operation of energy storage (battery) systems, prototyping and implementing various battery management system (BMS) interfacing solutions, configuring software on Linux-based computers, adhering to safety standards when working with high-voltage systems, and testing software applications in real-world factory settings to ensure they function correctly.

Collaborate with battery engineers, firmware developers, and system integrators to understand tooling needs and requirements for battery management systems (BMS) and related applications. Design, develop, and maintain solutions and utilities to automate battery testing, data analysis, simulation, and optimization processes. Implement software solutions to monitor battery performance metrics, conduct diagnostics, and facilitate predictive maintenance. Create user-friendly interfaces and dashboards for visualizing data and configuring parameters related to battery management and testing.

Integrate tools with existing frameworks and platforms, ensuring compatibility and scalability. Document tool functionality, usage guidelines, and best practices for internal teams.

Proficiency in multiple programming languages such as C/C++, Rust, Java script, Python, or Java. Experience with data analysis tools and libraries (e.g., Pandas, Num Py) for processing and interpreting battery performance data. Familiarity with version control systems (e.g., Git), build tools (e.g., CMake), and continuous integration (CI) pipelines. Familiarity with issue/project tracking software (e.g., JIRA). Ability to obtain strong understanding of battery management systems (BMS), battery modeling, and simulation techniques.

Knowledge of communication protocols used in battery systems (e.g., CAN, Modbus, HTTP) and familiarity with hardware-in-the-loop (HIL) testing. Excellent problem-solving skills and attention to detail. Strong communication and collaboration skills, with the ability to work effectively in a cross-functional team environment. Experience with real-time operating systems (RTOS) and embedded software development. Understanding of regulatory standards and safety protocols related to power plant equipment.

Familiarity with agile methodologies and Dev Ops practices.

Bachelor's degree in computer science, software engineering, or related field required. Master's degree in computer science, software engineering, or related field preferred. Minimum of 2 years' experience.
