Role Description

Form Energy is hiring a Staff Mechanical Engineer to lead the design of LV and HV harness mechanical architecture for large battery systems. This role reports to the HV & LV Systems Design team. As part of our team, you will lead wire harness mechanical routing, connector selection, cable specification, and 2D drawings in collaboration/partnership with mechanical and electrical teams. This is an exciting opportunity to help shape and be part of the growth of a fast‑moving company with breakthrough technology and an incredible mission! Relocation assistance is available.

What you’ll do:

• Develop LV & HV harness design from early concept phase all the way through production, and support post‑production ramp up and cost down efforts for electromechanical battery systems
• Lead cross‑functional alignment between Mechanical, Electrical, Sensor, Harness, Structural, Assembly and Supply Chain teams, perform trade‑off studies between function, performance, cost and DFM/DFA
• Identify, evaluate, select, and procure harness components for high‑volume production
• Create 3D routing in CAD and sync with harness tools such as Zuken to generate final assembly drawings for fabrication
• Work with external suppliers and internal cross‑functional teams (quality, supply chain, mfg etc.) to take 3D designs to physical product for development
• Design harness for harsh environmental conditions (ie high pollution degree, ingress protection etc.)
• Help create Design and Quality standards for wire harnesses, specific to Form’s battery applications

What you’ll bring:

• Minimum of 7 years of relevant harness mechanical design experience
• Knowledge of battery systems, high voltage systems, EMC Strategies, and communications protocols (CAN, LIN, Ethernet)
• Proficient in SolidWorks, both harness and general mechanical design as well as basic mechanical and thermal simulations
• Solid mechanical engineering fundamentals: thermal, vibration, durability, corrosion‑prevention, materials, etc.
• Demonstrated effectiveness in handling multiple priorities, proactively organizing workloads, and meeting tight delivery timelines
• Detail‑oriented personality with effective documentation and reporting
• Preferred experience with GD&T and design for high volume manufacturing
• Bonus: Zuken harness design experience
