Sr. Test and Product Development Engineer – WBG power semiconductors

About EPC Space

EPC Space is a joint venture between Efficient Power Conversion (EPC) and VPT, Inc. (a HEICO company). We specialize in designing and manufacturing radiation-hardened (Rad Hard) gallium nitride (GaN) power transistors, ICs, and modules for satellite, deep space, and other harsh-environment applications.

Our enhancement-mode GaN devices deliver superior efficiency, smaller size, lighter weight, and better radiation performance compared to traditional silicon MOSFETs. They power critical space systems including DC-DC converters, motor drives, LIDAR, and ion thrusters. Join us in bringing revolutionary GaN technology to the next generation of space missions.

Key Responsibilities:

• Test Development and Support: Develop and oversee test hardware/program development for ATE (Automated Test Equipment), ensuring coverage for functional, parametric, and system-level testing.
• Yield Improvement and Optimization: Analyze assembly and test data to drive yield enhancements, reduce defects, and optimize processes in internal facilities. Collaborate closely with front-end fab and design teams for holistic improvements.
• Product Lifecycle Management: Oversee the full back-end process from wafer receipt through assembly, testing, and packaging qualification to volume production and sustainment.
• New Product Introduction (NPI): Coordinate qualification of new devices, including process development, test program validation, and ramp to high-volume manufacturing. Ensure seamless handoff from R&D/design to production.
• Quality and Reliability Engineering: Perform failure analysis, root cause investigations, and reliability qualifications. Manage product qualifications and compliance for internal standards.
• Cross-Functional Integration: Work directly with design, process integration, fab operations, and quality teams to resolve issues. Support product changes, cost reductions, and continuous improvement (e.g., Six Sigma projects)
• Sustaining Engineering: Monitor production metrics, handle excursions, implement corrective actions, and support end-of-life or portfolio management for mature products

Qualifications:

• Education: Bachelor’s or Master’s degree in Electrical Engineering.
• Experience: 3-8+ years in semiconductor test and or back-end processes (assembly, packaging).
• Required Skills:
  • Knowledge of power semiconductor products and testing techniques
  • Proficiency in test development, including custom fixtures and dedicated bench test setups (hardware + automation)
  • Familiarity with reliability testing and standards
  • Strong problem-solving, project management, and communication skills for internal collaboration.
