Principal Engineer, Advanced Power Engineering

Flex is the diversified manufacturing partner of choice that helps market-leading brands design build and deliver innovative products that improve the world.

A career at Flex offers the opportunity to make a difference and invest in your growth in a respectful inclusive and collaborative environment. If you are excited about a role but dont meet every bullet point we encourage you to apply and join us to create the extraordinary.

Flex intends to spin off its Cloud and Power Infrastructure segment into a new independent publicly traded company which were calling SpinCo until the name is unveiled. The spin is planned for Q1 2027. If the intended spin occurs this role will support SpinCo which will focus on critical digital infrastructure delivering end-to-end power and thermal management solutions for AI data centers and other mission-critical applications.

To support our extraordinary teams who build great products and contribute to our growth were looking to add a Principal Engineer Advanced Power Engineering located in Austin TX.

Reporting to the Chief Technology Officer the Principal Engineer Advanced Power Engineering will lead the research development and technical roadmap for next-generation data center power solutions that enable SpinCos integrated productized data center strategy. This role is responsible for defining and advancing power architectures across medium-voltage and low-voltage systems power distribution energy storage high-voltage and medium-voltage DC concepts on-site generation integration grid-interface technology and power pods or skids. The role will partner closely with our power business units manufacturing supply chain customers and ecosystem partners to translate advanced power concepts into scalable productized solutions.

This is a hands-on technical leadership role. You will be in the details generating architectures models specifications and analysis yourself rather than only directing others to do so. We are looking for a leader who can run a full design-build cycle set the technical bar by example and is measured more by working hardware and validated designs than by decks and white papers.

What a typical day looks like:

• Define and maintain the multi-generation power technology roadmap aligned to hyperscaler leading silicon grid-interface and AI infrastructure requirements.
• Lead applied R&D architecture development and prototype execution for advanced power subsystems including power pods and skids MV e-houses advanced conversion systems energy storage integration sidecar architectures and next-generation high-voltage DC reference designs.
• Establish interface standards and integration requirements for power systems within SpinCos integrated data center platform.
• Serve as SpinCos technical authority for advanced power in customer engagements strategic partnerships industry forums and standards discussions.
• Partner with Systems Architecture Engineering to ensure power systems are co-engineered with cooling controls IT infrastructure and modular product designs.
• Support technical due diligence for acquisitions partnerships and supplier ecosystem decisions related to power and energy infrastructure.
• Mentor and develop a high-performing advanced power engineering bench across SpinCo including close partnership with the cross-functional engineering teams responsible for specialized areas of the data center stack.

The experience were looking to add to our team:

• Bachelors degree in Electrical Engineering Power Electronics Energy Systems or related technical field; Masters or PhD preferred or equivalent experience.
• 12 years of engineering experience in power electronics data center power critical power infrastructure utility-scale power or power products manufacturing.
• Demonstrated leadership in electrical mechanical and/or systems architecture engineering disciplines
• 5 years leading technical teams advanced engineering teams or architecture programs.
• Deep knowledge of AC/DC power architectures MV/LV systems power conversion energy storage grid interconnection redundancy reliability and data center power delivery.
• Experience translating future technology concepts into executable product requirements prototypes and manufacturable platforms.
• Strong customer-facing technical leadership with hyperscale colocation AI infrastructure or critical power customers.
• Hands-on power architecture and design experience with a personal portfolio of schematics models and prototypes you drove to working hardware.
