Mechanical Design Engineer - Stealth Startup JB-5561

For a young and dynamic startup developing electromagnetic (millimeter-wave) deep drilling technology, with the goal of making geothermal energy accessible anywhere in the world – a technology expected to dramatically change the energy market.

We are looking for a Senior / Lead Mechanical Engineer who thrives in early-stage environments and knows how to take complex systems from idea to working hardware. The role requires creativity, independence, leadership and influence – full ownership from concept and CAD through prototype and field testing.

Key Responsibilities:

• Lead mechanical design of drilling systems
• Develop large mechanical assemblies (meter-scale), including energy transmission, thermal management and fluid-flow systems
• Perform FEA and structural analysis
• Design for manufacturability (DFM) and cost efficiency
• Plan and execute lab and field testing
• Work closely with RF, thermal and fluid engineers on system integration
• Coordinate with suppliers and manufacturers in Israel and abroad
• Create and maintain complete engineering documentation

Location: Tel Aviv

Requirements

• 5+ years of mechanical design experience, across all stages of the product development cycle
• Strong proficiency in SolidWorks or similar 3D CAD software
• Hands-on experience with FEA, DFM and materials selection
• Proven experience designing and building complex mechanical systems
• Ability to work independently, lead and influence, and move projects forward in uncertain environments
• Experience with large mechanical systems (meter scale) – advantage
• Experience with fluid-flow systems (hydraulics / chemical or process industry) – advantage
• Experience with high-power thermal systems – advantage
• Hands-on experience assembling and testing hardware – advantage
