Lead Hardware Engineer - Robotics for GW-Scale Energy Infra

TAR; San Francisco (CA); On-site; USD 140,000 - 210,000; Full time

Job summary

TAR builds fully islanded solar and storage campuses delivering clean, firm power directly to AI data centers, with no grid connection. As Lead Hardware Engineer, you own the mechanical, electrical, and systems design of a core robotics subsystem—from prototype through field-hardened production—and lead a small team of hardware engineers.

Regular site visits supplement the San Francisco robotics facility work.

Qualifications

• 5-7 years hardware engineering experience with leadership experience
• Experience moving a subsystem from prototype to production
• Strong grounding in mechatronics or mechanical engineering
• Experience managing BOMs and reducing costs
• Ability to communicate design trade-offs to management and cross-functional partners

Responsibilities

• Own the technical design and roadmap for a defined robotics subsystem
• Lead a small team of mechanical, electrical, and systems engineers
• Advance subsystem from prototype to higher-volume production with partners
• Make system architecture decisions for mechanical, electrical, controls, and sensors in harsh field conditions
• Manage BOM and supplier relationships balancing cost and reliability
• Spend time at field sites to close the loop between failures and fixes
• Collaborate with the Head of Hardware on hiring and roadmap input
