Job description

At Re:Build, our mission is to ensure the next generation of important products are made, at scale, in America. We are laying the foundation for a better future for our customers, employees, and communities by revitalizing America's manufacturing base and creating meaningful jobs across the country, including in historically deindustrialized regions.

We operate an advanced, end-to-end manufacturing platform that partners with industrial companies and innovators to take products from first concept to full-scale production in critical verticals including aerospace and defense, electrification, medical, energy and environment, and robotics and automation.

The way we operate is as important as the work we do. It's guided by The Re:Build Way, 16 principles that shape how we collaborate with each other, partner with our customers and vendors, and contribute to the communities where we operate. (link to The Re:Build Way principles)

Who we are looking for

As an Electrical Engineer at Re:Build, you will play a pivotal role in the design and development of advanced lithium-ion battery systems. You will be responsible for defining system architecture, creating electrical schematics, selecting and integrating electronics hardware, and performing critical thermal and power dissipation analyses. Your expertise will directly influence key technical decisions that enable Re:Build to deliver safe, high-performance battery modules and packs across automotive, aerospace, renewable energy, and industrial applications.

You will support all phases of the program lifecycle — from concept design through prototyping, validation, and launch — working cross-functionally with mechanical, software, and manufacturing teams. Success in this role requires strong technical fundamentals, excellent analytical and problem-solving skills, and the ability to clearly communicate complex technical concepts to both internal and external stakeholders.

What you get to do

• Develop Electrical System Architecture: Define and document high- and low-voltage distribution, interfaces, and protection systems for battery packs.
• Create Electrical Schematics: Own the schematic design of battery pack systems, including sensors, contactors, fuses, connectors, harnesses, and control electronics.
• Select and Integrate Electronics Hardware: Evaluate and specify components such as current sensors, power electronics, microcontrollers, and supporting hardware for safety, performance, and manufacturability.
• Perform Thermal & Power Dissipation Analysis: Conduct hardware heating and power dissipation calculations to ensure reliable operation across environmental and load conditions.
• Support Circuit Design & Validation: Contribute to the design, simulation, and bench testing of circuits for measurement, control, and protection.
• Ensure Safety & Compliance: Support DFMEA, functional safety (ISO 26262 or equivalent), and industry compliance requirements, including UL.
• Collaborate Across Functions: Partner with mechanical, software, program management, and manufacturing teams to integrate electrical design into robust and manufacturable products.
• Test & Debug: Develop validation test plans, analyze data, and troubleshoot electrical issues.
• Communicate Results: Prepare and present technical findings and recommendations to customers, suppliers, and internal leadership.

What you bring to the team

• 3+ years of experience in system-level design for lithium-ion battery packs or related electrical systems.
• 4+ years of engineering experience in automotive, aerospace, industrial, or related sectors.
• Strong proficiency in electrical system design and schematic capture.
• Knowledge of electronics hardware thermal management and power dissipation analysis.
• Experience with component selection and integration for high-voltage and low-voltage systems.
• Familiarity with high-voltage safety standards, EMC/EMI practices, and grounding/shielding.
• Excellent verbal and written communication skills, with the ability to explain complex technical issues clearly.
• Strong problem-solving skills and demonstrated ability to work in fast-paced, cross-functional environments.
• Bachelor of Science in Electrical Engineering (or related discipline) with strong emphasis on practical application and systems design.

Additional Preferred Qualifications

• M.S. or Ph.D. in Electrical Engineering or related discipline.
• Hands-on experience with battery management systems (BMS), control algorithms, or embedded electronics.
• Background in functional safety (ISO 26262) or equivalent standards.
• Experience with project leadership or cross-functional technical coordination.
• Familiarity with mathematical modeling of batteries and/or experimental validation methods.
