About The Position

As a Senior ATE Mechanical Engineer at Lunar, you will be responsible for the full product development lifecycle of mechanical systems within the company’s home energy products. You will work closely with a small, dedicated team and contribute across product design, testing, manufacturing, and supplier support. The role involves applying physical principles to design, supporting high-volume production, and helping develop clean-energy products intended to electrify homes and connect communities into resilient virtual power plants.

The work includes developing and evaluating design solutions; testing ideas through calculations, physical tests, and simulations; designing reliable, manufacturable parts and assemblies; preparing drawings and specifications; and managing bills of materials, cost and mass roll-ups, vendors, and engineering releases. You will define manufacturing processes and inspection methods, support prototypes and production with part manufacturers, and provide onsite build support at domestic and international contract manufacturing sites. Approximately 10–20% travel may be required as needed.

• Experience with PCBA management, such as Mechanical Control Outline generation.
• Working knowledge of pneumatic cylinders and control methods.
• Working knowledge of thermal management techniques.
• Prototyping skills using 3D printing, machining, sheet-metal bending, laser cutting, milling, and general machine-shop tools.
• Experience communicating with component suppliers, including Design for Manufacturing report review, First Article Inspection, and Part Production Approval Process.
• Ability to generate work instructions for electromechanical assemblies.
• Knowledge of Process Failure Modes and Effects Analysis.
• Ability to generate detailed design documentation.
• Ability to drive a project from start to deployment involving cross-functional teams, vendors, and technicians.
• Ability to collaborate with electrical engineers, automated test engineers, and other engineers.
• Clear verbal and written communication skills, including concise slide-deck creation.
• Ability to give kind and direct feedback and receive feedback with an open mind.

Responsibilities

• Collaborate across the company to refine product understanding and improve product impact, time to market, and reliability.
• Brainstorm, evaluate, and narrow down design solutions.
• Test ideas and designs using calculations, physical tests, and multiphysics simulations.
• Design high-performance, reliable, easy-to-manufacture parts and assemblies for high-volume manufacturing.
• Create and review drawings and part specifications.
• Manage bills of materials, cost and mass roll-ups, vendors, and engineering releases.
• Define manufacturing processes and inspection methods.
• Work directly with part manufacturers to support prototypes and production.
• Manage suppliers for parts required for station construction.
• Provide onsite build support at domestic and international contract manufacturing sites.
• Review Design for Manufacturing reports, First Article Inspections, and Part Production Approval Process activities with component suppliers.
• Generate work instructions for electromechanical assemblies and preventive maintenance documentation.
• Drive projects from initiation through deployment, coordinating cross-functional teams, vendors, and technicians.
• Communicate design information and provide and receive feedback constructively.

Benefits

• Equity in a fast-growing company through the employee stock program.
• Medical, dental, and vision insurance for employees and dependents.
• Flexible Paid Time Off and 10 paid holidays.
• Tax-deferred 401(k) plan.
