Mechanical Systems Integration & Test Engineer, Grid Power

Heron Power; Scotts Valley (CA); On-site; USD 90,000 - 140,000; Full time

Job summary

Heron Power seeks a Mechanical System Integration and Test Engineer to architect, build, and operate fixtures and test infrastructure for medium‑voltage power converters. You will anchor the integration from architecture input through reliability sign‑off, owning test execution, data analysis, and failure investigation.

You will design mechanical fixtures, integration layouts, and packaging interfaces while advancing reliability through physics‑of‑failure models and controlled testing campaigns.

Qualifications

• Bachelor's degree in mechanical engineering, mechatronics, or similar.
• 3+ years of full-time industry experience designing mechanical fixtures, test hardware, or electro-mechanical assemblies.
• Strong experience with 3D CAD (CATIA V6/3DX preferred).
• Experience designing fixtures or test setups for manufacturing, IP ingress, or shock/vibration.
• Experience with reliability modeling and failure analysis on mechanical components.
• Experience defining instrumentation and DAQ for long-duration testing.
• Ability to manage interfaces between mechanical and electrical subsystems.
• Hands-on test execution and early-architecture influence.

Responsibilities

• Own the full test cycle for mechanical components: plan, fixture design, execution, and data analysis.
• Develop physics-of-failure models translating stresses into degradation and lifetime.
• Run IP, shock/vibration, and accelerated life testing hands-on.
• Define instrumentation and DAQ plans for long-duration tests.
• Lead root-cause analysis on mechanical failures and drive fixes.
