Experience:

• A bachelor’s degree in mechanical engineering, Physics, or a related field.
• Minimum of 5 years of relevant experience, ideally within a startup or technology company.

Skills:

• Deep working knowledge of multiple ME topics and strong understanding of standard mechanical engineering degree curriculum.
• Deep understanding of material properties, mechanisms, fabrication methods: CNC milling, CNC turning, sheet metal, injection molding, laser cutting, water jet cutting, and 3D printing (metal and plastic).
• Deep understanding of designing for photonic assembling methods: Die bonding, vacuum reflow soldering, wire‑bonding, adhesives, etc.
• Deep understanding of structural theory: static, modal, random vibration, shock, etc.
• Deep understanding of fluids and heat transfer theory: conduction, convection and radiation.
• Demonstrated successful execution of engineering tasks including use of mechanical CAD (SolidWorks preferred) and quantitative analysis/programming tools (Python), instrumentation and measurement, part fabrication or procurement, integration and test, data collection, analysis (ANSYS Workbench) and documentation.

Startup Mindset:

• You're creative, flexible, and eager to wear multiple hats.
• You're passionate about building systems from the ground up and comfortable with ambiguity and change.

The expected annual salary range for this position is $125,000-$175,000.
