Job description

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 don't meet every bullet point, we encourage you to apply and join us to create the extraordinary. Job Summary To support our extraordinary teams who build great products and contribute to our growth, we're looking to add a Principal Engineer, Systems Architecture Engineering located in Austin, TX. Reporting to the Chief Technology Officer, the Principal Engineer, Systems Architecture Engineering will define the integrated data center and modular systems architectures that convert SpinCo's power, cooling, IT infrastructure, controls, and software capabilities into a coordinated platform. This role owns reference architectures for modular and stick-built data centers, prefabricated modular and high-density compute product lines, system-level interfaces, and complex controls systems architecture and development. The position is central to making SpinCo's integrated, productized data center vision operational. 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: Own the system-level reference architectures for integrated data centers, modular data centers, prefabricated modular offerings, and high-density compute product lines. Define complex controls systems architecture spanning SpinCo power, cooling, telemetry, control systems, and AI-driven optimization. Establish system interfaces, integration standards, architecture specifications, block diagrams, and technical requirements that allow SpinCo and partner subsystems to operate as a coordinated platform. Lead development of the SpinCo reference design library from early concept through production-level design maturity in partnership with business units and engineering teams.
