About the Role
You will develop battery systems for humanoid robots from architecture and component selection through prototyping, characterization, validation, and production. You will work hands-on with cells, modules, packs, test systems, and complete robots to improve performance, safety, lifetime, and manufacturability. You will analyze test and operational data, address failure modes, and collaborate on integrated energy systems through production ramp.
Requirements
•Bachelor's degree in Mechanical Engineering, Electrical Engineering, Chemical Engineering, Materials Science, or a related engineering field.
•5+ years of engineering experience developing battery systems, energy storage systems, or complex electromechanical products.
•Experience developing fixtures and test equipment.
•Experience developing lithium-ion battery packs, modules, cells, or related energy storage systems.
•Understanding of lithium-ion cell performance, charging and discharging behavior, degradation, thermal behavior, and safety.
•Experience with battery pack architecture and integration.
•Experience defining and executing battery characterization and validation testing.
•Experience analyzing battery performance data and using test results to drive engineering decisions.
•Experience with battery safety, fault analysis, failure modes, and design mitigation strategies.
•Experience supporting hardware from prototype development through design validation and production.
•Experience collaborating with electrical, mechanical, embedded software, manufacturing, quality, reliability, and supply chain organizations.
Responsibilities
•Design and release production-ready battery systems that meet energy, power, weight, volume, thermal, safety, reliability, cost, and manufacturability requirements.
•Develop battery pack architectures integrating cells, busbars, interconnects, sensing, protection, BMS hardware, thermal management, enclosures, and structural interfaces.
•Define and validate cell and pack performance requirements across charge, discharge, peak power, temperature, aging, and robot duty cycles.
•Improve battery energy density, power capability, thermal performance, cycle life, reliability, and serviceability through engineering and testing.
•Develop characterization and validation methods for cells, modules, packs, charging systems, and battery safety.
•Identify battery failure modes through testing and data analysis and drive design improvements and corrective actions.
•Support battery hardware through prototype builds, design validation, NPI, supplier qualification, and production ramp.
•Partner with electrical, embedded software, mechanical, controls, reliability, manufacturing, and supply chain teams to deliver integrated energy systems.
Benefits
•Comprehensive medical, dental, and vision coverage.
•Generous paid time off, company holidays, and parental leave.
•401(k) plan with company match.
•Flexible Spending Account and Health Savings Account options.
•Commuter benefits for transit and parking.
•Short-term and long-term disability insurance and life insurance.
•Employee Assistance Program for mental health, financial, and personal support.
•Onsite snacks and catered lunches.
