Senior Firmware Engineer

About Moment Energy

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.

Now is the moment. Join us.

Our Values

Our values are key to how we show up every day at Moment Energy! We keep them in the forefront of what we do, and they’re used everywhere. We refer to them when we have tough decisions to make, we give shoutouts based on living out these values, and we include them as part of our performance reviews.

We have 5 core values and 1 foundational pillar (Safety is our Foundation) which lays the groundwork for everything we do.

Safety is our Foundation

We prioritize the safety of our products, customers, employees, and the general public above all else. From the workshop to the field, we maintain the highest standards for our batteries in testing manufacturing and deployment, and daily operations. Safety is not only about procedures—it is about vigilance, responsibility, and speaking up when something does not feel right.

Safety is everyone's responsibility. We follow safety protocols, use proper equipment, and continuously improve our systems to prevent risks before they occur. If something is unsafe, we stop work and address it.

Safety also means protecting our colleagues, customers, and communities by designing reliable products, maintaining safe workspaces, and ensuring our work is done carefully and responsibly.

We’re Building a Greener Future Together:

We infuse passion for our cleantech mission into every aspect of our work and incorporate fun into the workplace. We motivate one another, celebrate our successes and embrace eco‑friendly practices to reduce our carbon footprint.

We Prioritize our Customer’s Needs:

We place our customers at the core of everything we do, ensuring that every decision considers their needs and aims to provide increased value to them. We provide reliable support for our customers, every step of the way.

We’re Open, Honest and Accountable:

We prioritize open and honest communication to foster mutual understanding, strengthen knowledge sharing, and reduce miscommunication within the team. We admit when we’ve made a mistake, and remedy our actions. We transparently communicate outcomes whether good, bad, or unexpected.

We Think and Act like Owners:

We’re self‑starters that proactively embrace new challenges along with personal and collective ownership of responsibilities in the organization. We focus on growth, not titles, and we do what needs to be done.

We Treat Everyone with Respect:

We actively listen, share openly, and work together towards common goals. We treat one another with mutual respect to cultivate an inclusive environment where everyone feels accepted, supported, and heard. We keep an open mind and are willing to learn.
