Job description

Archer is an aerospace company based in San Jose, California building an all-electric vertical takeoff and landing aircraft with a mission to advance the benefits of sustainable air mobility. We are designing, manufacturing, and operating an all-electric aircraft that can carry four passengers while producing minimal noise.

Our sights are set high and our problems are hard, and we believe that diversity in the workplace is what makes us smarter, drives better insights, and will ultimately lift us all to success. We are dedicated to cultivating an equitable and inclusive environment that embraces our differences, and supports and celebrates all of our team members.

As a BMS Electrical Engineer, you will own hardware designs for Archer’s high voltage battery management system.

Responsibilities

• Lead design of BMS PCBAs, through their full lifecycle - including circuit simulation, schematic capture, layout, routing, reviews, manufacturing, and revisions
• Work closely with mechanical and software teams, from the beginning of the design process, to ensure that our BMS hardware seamlessly integrates into the battery pack
• Design circuits for diagnostic coverage, redundancy, and fault‑tolerance - working closely with systems and safety teams to ensure that our BMS hardware meets safety goals
• Own PCBA bring‑up and verification, working hands‑on with lab equipment to check that the design functions across all operating conditions and fault injection cases
• Support software development related to new circuits and revisions, updating and authoring interface documents as needed
• Coordinate builds with PM team, DFM team, supply chain team, and quality team
• Support production & manufacturing needs, including design‑for‑test, root‑cause analysis of failures, component traceability, and build process development
• Work with cross‑functional teams to ensure smooth integration of the battery pack with other electrical systems on the aircraft
• Work with BMS integration, software, and controls engineers to facilitate hardware fault injection tests on HILs and packs

What You Need

• BS or MS degree in Electrical Engineering, Mechanical Engineering or a related field
• 3+ years of experience designing and verifying complex electrical circuits
• Experience with high voltage battery systems and BMS electronics
• Experienced in Altium Designer and circuit simulation tools such as LTSpice
• Detailed knowledge of PCB design rules including IPC‑610 / 2221 / 2222
• Excellent organizational, communication, and troubleshooting skills

Bonus Qualifications

• Experience designing for HV battery systems in both aviation and automotive contexts
• Layout experience with both flexible and rigid board stackups
• Experience with new product development in regulated industries (e.g., aviation, medical devices)
• Experience with DO‑160G, ISO 26262, or related standards
• Experience designing to industry standards for electromagnetic emissions and susceptibility
