Battery Test Engineer

About ALSO

ALSO is an electric mobility company originally conceived as part of Rivian. We're a team of builders, dreamers, and innovators focused on creating vertically integrated, small electric vehicles designed to meet global mobility challenges. Our mission is to inspire everyone to ride ALSO—replacing local car, truck, and SUV miles with vehicles that are more affordable, more enjoyable, and 10–50x more efficient.

The Role

We're looking for a Battery Test Engineer to own battery validation strategy, including safety testing, for our vehicle platforms. This is not a test execution role—you'll define what needs to be tested, determine what good looks like, build the capability required to validate it, and help drive engineering decisions that determine product readiness and reliability.

You'll be equally comfortable building prototype hardware, designing tests, developing automated test capability, analyzing test data, performing failure analysis, and making clear engineering judgments about system readiness and safety risks.

What You'll Do

• Define validation strategy for electromechanical hardware from prototype through production release, determining test requirements and sign-off criteria
• Design test methodologies reflecting real-world operating conditions, manufacturing variation, and long-term usage across mechanical, electrical, thermal, performance, reliability, durability, environmental, and abuse domains
• Build and bring up prototypes and test hardware hands-on, owning instrumentation, debugging, and root-cause analysis
• Design fixtures, automation tools, and lab infrastructure to improve test quality, repeatability, and speed
• Analyze test data and translate findings into clear design actions and program risk assessments
• Partner with Battery Design, BMS, Systems, and Vehicle Engineering teams to ground validation in real use cases
• Coordinate with external test labs, certification agencies, suppliers, and contract manufacturers for compliance and validation
• Set standards for rigor, speed, and quality as an early member of a growing test engineering team

What You'll Bring

• BS/MS in Mechanical Engineering, Electrical Engineering, or related field
• Ability to bound problems from first principles in electrochemistry, thermal dynamics, and mechanical systems
• Hands-on experience designing and executing validation tests for electromechanical systems, batteries, or power systems
• Proficiency with test automation, data acquisition, and instrumentation tools
• Experience with failure analysis, root-cause investigation, and translating findings into actionable engineering decisions
