Responsibilities
We compromise nothing and heavily value first principles engineering. Our ideal candidate exhibits a can-do attitude, demonstrates excellence in their respective fields, and possesses the ability to adapt quickly within a fast-paced environment. They are always striving to push the envelope of what’s possible.
Own The Design: Lead the mechanical architecture, packaging, integration, and validation of core power electronics systems, including onboard chargers, DC-DC converters, and HV junction boxes.
Managing every aspect of design engineering from concept to production and beyond.
Develop system-level solutions that balance electrical performance, mechanical robustness, manufacturability, cost, serviceability, and customer experience.
Lead supplier technical reviews, DFMEA reviews, tooling reviews, validation alignment, and production launch activities.
Prototype & Test: Design, build, and test your prototypes
Define and support executing environmental, vibration, thermal shock, temperature cycling, ingress protection, durability, and mechanical qualification testing
Drive design changes based on test results and real-world feedback.
Innovate & Optimize: Continuously optimize designs for cost and performance without sacrificing safety or reliability.
Collaborate: Work closely with electrical engineers, quality assurance, manufacturing, and other cross-functional teams to ensure seamless integration of mechanical and electrical systems.
Mentor: Provide technical guidance to junior engineers, lead internal design reviews, and drive engineering decisions through analysis, testing, and first-principles reasoning.
Continuously Learn: Embrace new challenges and expand your engineering skills in a fast-paced, dynamic environment.
