BESS Expert Software Engineer

Strata Clean Energy seeks an Expert Software Engineer specializing in Battery Energy Storage Systems (BESS) to design and develop software solutions for energy storage operations. Responsibilities include developing robust applications, APIs, and monitoring tools, collaborating with engineering teams, and ensuring software reliability and cybersecurity. Candidates should have significant experience in software engineering, particularly in energy systems. The position is primarily remote with occasional travel (10-20%) required.
Strata Clean Energy is looking for a highly skilled Expert Software Engineer with deep expertise in Battery Energy Storage Systems (BESS). In this role, you will lead the design, development, and deployment of software solutions that enable intelligent control, monitoring, and optimization of large-scale energy storage systems, often integrated with solar PV.

Your work will be instrumental in building the digital infrastructure that ensures reliable, responsive, and revenue-generating battery storage operations across a diverse portfolio. You’ll collaborate closely with hardware engineers, data scientists, control systems experts, and field technicians to bring innovative, scalable energy solutions to life.

Key Responsibilities
• Design and develop robust software applications and control logic for utility-scale and C&I BESS systems.
• Develop APIs and data pipelines to interface with BMS, EMS, SCADA, and site-level controls using standard protocols (e.g., Modbus, DNP3, OPC UA).
• Build and maintain real-time monitoring, control, and diagnostic tools to support grid-tied and off-grid energy storage operations.
• Collaborate with systems engineers and product managers to define software architecture for energy optimization, charge/discharge scheduling, fault handling, and grid services participation.
• Integrate battery controls with solar PV systems and utility networks.
• Ensure cybersecurity, resilience, and reliability of software systems in distributed field deployments.
• Participate in firmware/software-in-the-loop testing with hardware teams and support field commissioning as needed.
• Continuously improve software reliability, scalability, and performance based on user feedback and operational data.
• Mentor junior engineers and contribute to coding standards, code reviews, and best practices.

Qualifications

Required:
• Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or a related field.
• 7+ years of software engineering experience, including 3+ years focused on energy systems, BESS, or industrial controls.
• Strong proficiency in languages such as Python, Java, C/C++, or Go, with experience in real-time or embedded systems.
• Deep understanding of communication protocols and industrial interfaces (e.g., Modbus, CANbus, OPC, TCP/IP).
• Experience with energy management systems (EMS), distributed energy resource management systems (DERMS), or SCADA platforms.
• Demonstrated ability to write clean, maintainable, and scalable code for production environments.
• Experience deploying software in Linux-based, networked, and remote operational environments.

Preferred
• Familiarity with BESS OEM platforms (e.g., Tesla, Fluence, Powin, Sungrow).
• Experience with cloud-based infrastructure (e.g., AWS, Azure) and containerization (Docker, Kubernetes).
• Knowledge of power systems, grid integration, and market participation strategies (e.g., frequency response, arbitrage).
• Hands-on experience with control algorithm development or model predictive control (MPC).
• Understanding of cybersecurity standards for critical infrastructure (e.g., NERC CIP, IEC 62443).

Work Environment & Travel
• Primarily remote with occasional travel (10–20%) to field sites or testing labs.
• May involve support during critical commissioning or software deployment windows.
