Senior Firmware Engineer

Independent energy is here. Help us deploy it.

Energy should be free. Free from aging grids, fragile supply chains, and unnecessary extraction. At Moment Energy, we’re building a world where clean power is abundant, affordable, and uninterrupted for everyone.

The world doesn’t need another promise about energy; it needs proof that a freer future is possible. Moment Energy is the pragmatic liberator of power, the only company certified to turn the largest untapped energy supply into independent energy.

Now is the moment. While the industry scraps millions of batteries with decades of life left, we put them to work by repurposing large‑format batteries into advanced battery energy storage systems that deliver real‑world impact.

We were told second‑life batteries would never be safe enough or scalable enough. We didn’t argue, we engineered the solution. Today, Moment Energy delivers 5x the energy density and holds the certifications required to deploy energy independence at scale.

The Role

The Senior Firmware Engineer will contribute to the development of cutting‑edge firmware for our battery energy storage systems (BESS). As a Senior Firmware Engineer, you will play a crucial role in designing, implementing, and testing the embedded software that controls the core functionality of our BESS. You will work closely with hardware engineers, power electronics engineers, and data scientists to ensure seamless integration and optimal performance.

Responsibilities

• Design, develop, and maintain firmware for embedded systems used in battery energy storage systems (BESS).
• Write clean, efficient, and well‑documented code in C/C++ for micro controllers and embedded processors.
• Implement communication protocols (e.g., CAN, Modbus, Ethernet) for data exchange between BESS components.
• Develop and implement control algorithms for battery management systems (BMS), including cell balancing, state estimation, and fault detection.
• Collaborate with hardware engineers to define hardware‑software interfaces and ensure seamless integration.
• Perform rigorous testing and debugging of firmware to ensure reliability, safety, and performance, develop unit testing and integration testing with HIL systems.
• Stay up‑to‑date with the latest advancements in embedded systems and firmware development.
• Contribute to the continuous improvement of Moment Energy's firmware development processes.

The Candidate

We’re looking for individuals with the following traits, skills, and experiences:

• Bachelor's or Master's degree in Computer Engineering, Electrical Engineering, or a related field.
• 7+ years of experience in embedded firmware development, preferably in the renewable energy or automotive industries.
• Previous experience on safety‑critical software development and an understanding of relevant standards including ASIL.
• Strong programming skills in C/C++, with a deep understanding of embedded systems concepts.
• Experience with communication protocols (e.g., CAN, Modbus, Ethernet) and real‑time operating systems (RTOS).
• Familiarity with microcontroller architectures (e.g., ARM) and development tools.
• Experience with debugging tools (e.g., JTAG, oscilloscopes, logic analyzers).
• Excellent problem‑solving and analytical skills.
• Strong communication and teamwork skills.
• Passion for clean energy and a desire to make a positive environmental impact.

Why join us?

• Today, we’re delivering 5x the energy density and have all the certifications needed to ship energy independence to the world.
• Be part of a mission‑driven company focused on creating sustainable energy solutions and making a positive impact on the world.
• Collaborate closely with passionate co‑founders and a team committed to innovation and excellence.
• Contribute to building and scaling a company from the ground up, where your work will have a direct and meaningful impact.
• Thrive in a workplace that values collaboration, wellness, and celebrating successes, with regular company socials, fitness sessions, and more.
