Senior Failure Analysis Engineer

Mainspring EnergyMenlo Park, CA
Onsite

About The Position

Our Linear Generator is a sophisticated system integrating a wide range of engineering disciplines, including thermodynamics, mechanical, electrical, software, and controls. To support our rapid transition into volume manufacturing, we are actively expanding the scope and size of our Failure Analysis team. We are looking for a highly motivated Senior Failure Analysis Engineer with a strong electrical engineering background to join us. In this role, you will own the investigation of electrical failures, scaling our FA throughput and translating physics-of-failure insights into hardware improvements. This is a high-visibility and high-impact role where your findings will help steer design iterations, prevent escapes, increase test coverage, and help ensure the ultimate reliability of the fundamentally new class of power generation.

Requirements

  • Bachelor’s degree in Electrical Engineering, Physics, or a related technical discipline required
  • Minimum 5–8+ years of direct, applicable experience in failure analysis, electrical troubleshooting, or reliability engineering
  • Deep expertise in analyzing system-level electrical interactions, including hands-on experience identifying and mitigating EMC/EMI issues and environmental degradation
  • Proficiency with common structured problem-solving methodologies (e.g., 8D, Ishikawa diagrams, 5-Why analysis)
  • Strong verbal and written communication skills to construct clear FA reports and presenting technical data to cross-functional teams
  • Experience with coaching or mentoring junior engineers or laboratory technicians
  • Detail-oriented mindset with the ability to manage multiple priorities comfortably in a fast-paced, high-growth environment

Responsibilities

  • Lead Hands-on Investigations: Perform deep-dive troubleshooting and debugging on a wide variety of electrical enclosures and hardware, ranging from low-voltage logic controllers to high-voltage power switching systems
  • Drive Root Cause Analysis: Apply structured engineering and problem-solving methodologies to pinpoint mechanisms of failure, translating your findings into actionable containment, corrective, and preventive actions (CAPA)
  • Accelerate FA Throughput: Streamline diagnostic workflows and optimization techniques to increase the pace of our failure analysis loop, ensuring rapid feedback for fast-moving product upgrade programs
  • Collaborate Cross-Functionally: Work closely with Design Engineering, Manufacturing, Quality, Reliability, and field maintenance teams to clearly communicate data-driven FA findings and influence product improvements
  • Build the Knowledge Base: Document diagnostic workflows, teardown procedures, and failure-mode data to build a resourceful knowledge base
  • Coach and Mentor: Provide technical guidance, mentorship, and coaching to less experienced failure analysis engineers and technicians, raising the collective technical bar and impact of the team
