Mechanical Design & Test Engineer at Growth Expertz

Full‑Time | Onsite (Bay Area, California)

We’re hiring a Mechanical Design & Test Engineer for a mission‑driven clean‑energy startup developing next‑generation perovskite‑based solar technology. Ideal for engineers who enjoy hands‑on design, testing, and equipment development and want to contribute to breakthrough innovations in solar manufacturing.

You’ll design, procure, and install mechanical components and assemblies for thin‑film deposition and processing equipment used in perovskite photovoltaic development. Working closely with equipment engineering, process engineering, and technicians, you’ll improve process performance, optimize electro‑mechanical systems, and support scale‑up toward future manufacturing.

This role is highly cross‑functional and offers broad exposure across engineering disciplines, making it an excellent opportunity for someone who wants to grow quickly in a high‑impact, hardware‑focused environment.

• Design components for vacuum chambers and other processing equipment
• Create detailed drawings and collaborate with suppliers to source high‑quality, cost‑effective parts
• Perform mechanical, thermal, and structural analyses on assemblies
• Install, test, and troubleshoot systems alongside technicians
• Develop and execute test plans for in‑house electro‑mechanical equipment
• Adapt commercial equipment for perovskite cell production processes
• Work with process engineers to solve mechanical or operational challenges
• Contribute to improving engineering documentation and standards

• B.S. in Mechanical, Manufacturing, Industrial Engineering, or related discipline
• Experience using 3D CAD (Solid Works preferred) for machined, sheet metal, welded, or 3D‑printed components
• Comfortable working with suppliers, testing prototypes, and troubleshooting systems
• Interest in learning and improving engineering standards and best practices

• 3+ years working with vacuum systems or materials processing equipment (PV, semiconductors, batteries, etc.)
• Knowledge of ASME Y14.5M and tolerance analysis
• Experience with DFM/DFA and design for serviceability
• Background in CFD or FEA simulations (ANSYS or similar)
• Experience with document control systems and part/drawing release workflows

• Work with purpose: help advance next‑generation solar technology
• Be part of a team developing innovative clean‑energy solutions
• Excellent benefits including health coverage, 401(k) match, commuter benefits, and meaningful equity
• Growth‑focused culture with opportunities for conferences, training, and continuous learning
