Senior Electrical Systems Engineer, Batteries

Join Axon and be a Force for Good.

At Axon, we’re on a mission to Protect Life. We’re explorers, pursuing society’s most critical safety and justice issues with our ecosystem of devices and cloud software. Like our products, we work better together. We connect with candor and care, seeking out diverse perspectives from our customers, communities and each other.

Life at Axon is fast-paced, challenging and meaningful. Here, you’ll take ownership and drive real change. Constantly grow as you work hard for a mission that matters at a company where you matter.

Batteries are a critical subsystem in all modern mobile devices and require careful attention to safety, performance, reliability, and regulatory compliance. As the Senior Systems Engineer for Batteries within the Devices Hardware Engineering team, you will serve as the subject matter expert for battery technologies across Axon’s product portfolio.

In this role, you will provide technical leadership and guidance on the specification, design, integration, validation, and lifecycle management of battery cells and battery pack solutions. You will bring structure, rigor, and engineering excellence to how Axon evaluates and safely adopts emerging battery technologies in a rapidly evolving industry where both primary and rechargeable battery cells continue to increase in power and energy density.

You will lead the evaluation of new battery technologies, identify mature and suitable battery chemistries for Axon products, and drive battery strategy across multiple device platforms. Working closely with cross-functional engineering teams, you will establish battery selection criteria, lead supplier evaluations, and help standardize best-in-class battery solutions across the organization.

You will also partner with battery cell and pack suppliers to develop, qualify, and deliver battery subassemblies that meet stringent safety, performance, quality, and regulatory requirements. These solutions will support high-volume manufacturing of mission-critical products used by first responders and enterprise customers to capture truth, protect lives, and accelerate justice in the communities they serve.
