Staff ATE Mechanical Engineer
About The Position
As a Staff 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. The role involves collaborating closely with a small, dedicated team and contributing hands-on across product design, testing, manufacturing, and production support. Engineers apply fundamental physical principles, develop solutions that can be manufactured at high volumes, and work directly with suppliers. The position supports Lunar Energy’s mission to transition homes to 100% clean energy by developing clean energy products that electrify homes and connect communities to clean, resilient virtual power plants. The role includes designing and validating mechanical systems and components for automated test equipment (ATE) stations, supporting prototypes and production, and coordinating with cross-functional teams and domestic and international contract manufacturing sites. Travel is approximately 10–20% as required.
Requirements
- Extensive experience with 3D modeling software such as Onshape, NX, or SolidWorks.
- Knowledge of how to make a PCBA Bed of Nails fixture.
- Detailed knowledge of 2D drawing creation and GD&T.
- Ability to perform tolerance analysis and stack-up, statics and load-path analysis, finite element analysis, root cause analysis, and Design Failure Modes and Effects Analysis.
- Familiarity with electronic test equipment and basic electromechanical troubleshooting.
- Experience with test fixtures, jigs, and mechanical components for high-cycle-count applications.
- Experience with fine-pitch assemblies and construction.
- Ability to conduct strain-gauge measurements, understand stress on PCBAs, and incorporate designs to avoid that stress.
- 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 reviewing Design for Manufacturing reports, 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 create preventive-maintenance documentation.
- Extensive experience providing onsite build support at domestic and international contract manufacturing sites.
- Ability to generate detailed design documentation and communicate clearly in writing and verbally.
- Ability to lead projects through deployment while working with cross-functional teams, vendors, and technicians.
- Ability to collaborate with other engineers, including electrical and automated test engineers.
Responsibilities
- Collaborate across the company to refine product understanding and improve product impact, time to market, and reliability.
- Brainstorm and evaluate solutions, weigh trade-offs, and narrow down options.
- Test ideas and designs using calculations, physical tests, and multiphysics simulations.
- Design high-performance, reliable, easy-to-manufacture parts and assemblies using high-volume manufacturing processes.
- 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.
- Drive projects from initiation through deployment, coordinating cross-functional teams, vendors, and technicians.
- Collaborate with mechanical, electrical, and automated test engineers.
- Generate detailed design documentation and communicate clearly in writing and verbally, including through concise slide decks.
- Give direct, constructive feedback and receive feedback with an open mind.
Benefits
- Opportunity to receive equity in a fast-growing company and participate in its employee stock program.
- Medical, dental, and vision insurance for employees and dependents.
