What are the responsibilities and job description for the Lead Mechanical Design Engineer – High-Speed Rotating Machinery position at Sapphire Technologies?
Position Summary
Sapphire Technologies is seeking a Lead Mechanical Design Engineer to lead the development and production launch of advanced high-speed rotating machinery incorporating active magnetic bearings, high-speed electric machines, power electronics, and precision mechanical systems.
The role will support a major new product platform serving rapidly growing energy and thermal-management applications, including data-center infrastructure. The program is progressing from product development into validation and will require a significant production ramp over the next several years.
This is a hands-on technical leadership role with responsibility for mechanical architecture, system integration, validation, and production readiness. The successful candidate will lead a small team of engineers and designers while working closely with electrical, controls, manufacturing, quality, supply chain, and program-management teams.
Why Join Sapphire
Learning
Work at the intersection of high-speed rotating machinery, rotor dynamics, magnetic bearings, permanent-magnet machines, thermal management, precision manufacturing, and power electronics.
Impact
Own mechanical decisions that directly affect product performance, reliability, cost, manufacturability, and Sapphire’s ability to execute a major production scale-up supporting the growth of data-center infrastructure.
Becoming
Grow into a technical authority for high-speed magnetic-bearing systems, with opportunities to lead platform architecture, engineering teams, reliability initiatives, technology development, and future product programs.
Requirements
What Success Looks Like
First 90 Days
We offer a competitive benefits package designed to support the health, well-being, and financial security of our employees. Eligible team members receive paid vacation, paid sick time, comprehensive health benefits, and participation in a 401(k) retirement plan with company match. This role is based in a fast-paced manufacturing environment where teamwork, reliability, safety, and attention to detail are essential to success.
The above job description is not intended to be an all-inclusive list of duties and standards of the position. Incumbents will follow any other instructions, and perform any other related duties, as assigned, by their supervisor.
