Lead Mechanical Engineer

Matching People to Purpose in Renewable Energy

Series A Power Electronics Startup

My client is a well‑funded and rapidly growing startup building next‑gen power infrastructure to meet the explosive demand from AI data centers and renewable energy. Their technology directly addresses the bottlenecks preventing faster deployment of electricity generation and consumption.

Recent milestones:

• Secured $40M Series A funding from top‑tier Silicon Valley investors
• Selected for NVIDIA's Inception program for companies advancing AI infrastructure
• Team includes former Tesla Energy technical leaders who've shipped gigawatts worth of product‑category defining power electronics products
• Experiencing 300%+ YoY growth driven by hyperscaler data center demand

This org is solving one of the most pressing infrastructure challenges of the AI era: how to connect massive renewable generation and power‑hungry loads to an aging grid… faster, cheaper, and at scale.

As the Lead Mechanical Engineer
, you'll own the design and delivery of shipping‑container‑sized enclosures for multi‑megawatt power converters. This is end‑to‑end ownership, from first CAD model to high‑volume production, working alongside a tight‑knit team of mechanical, electrical, and manufacturing engineers. You'll be designing for extreme reliability in outdoor industrial environments: structural integrity, thermal management, weather sealing, EMI shielding, and compliance with grid interconnection standards.

• Mass‑manufacturable enclosure systems: sheet metal structures, structural plastics, seals, busbars, cable management, thermal systems
• First‑principles design approach: tolerance analysis, structural FEA, thermal modeling, ingress protection (IP ratings)
• DFM across processes: stamping, welding, die‑casting, injection moulding, riveting, dispensing
• Hands‑on prototyping, testing, and validation through environmental and compliance testing
• Cross‑functional collaboration with electrical, test, manufacturing, and supply chain teams
• Full product lifecycle ownership from concept → production release

CATIA V6/3DX (preferred), GD&T, tolerance analysis, FEA tools

• Strong first‑principles engineering approach and analytical rigo
• 5+ years designing outdoor‑rated industrial enclosures for electromechanical systems (power electronics, switch gear, industrial controls, battery storage, mechatronics, etc.)
• 5+ years professional experience with 3D CAD (CATIA is a major plus)

• Experience with: high‑volume manufacturing processes including sheet metal, injection moulding, welding, fastening, sealing
• Ingress protection (IP/NEMA ratings) and environmental sealing
• Coatings, paints, composites for outdoor applications
• Background in MV power distribution equipment, grid‑connected converters, or electrical power infrastructure
• Proven ability to lead designs from prototype → production independently
• Experience with FEA, CFD, thermal simulation (ANSYS, MATLAB, etc.)
• Reliability testing (DFMEA, DVP&R, HALT/HASS)
• Experience with PCBAs, busbars, HV DC connectors, fuses in electromechanical assemblies

• Ground‑floor opportunity at a Series A startup attacking a multi‑billion‑dollar infrastructure ecosystem
• Backed by top investors and validated by exploding customer demand and inclusion in NVIDIA's partner ecosystem
• Work with power electronics veterans with experience shipping industry‑defining products at massive scale
• Build equity in a company positioned at the intersection of AI, renewables, and grid modernization
• First‑principles culture:
  No bureaucracy. No constraints. The best ideas win.
