About the role

The Product Engineering Team at Fluidstack is responsible for architecting and developing the power and cooling systems that enable the company to deliver gigawatt-scale AI data centers faster and denser than traditional grid standards. Specifically, the SST group is focusing on solid-state transformers as a critical component of this power architecture.

Responsibilities

Architect a medium-voltage solid-state transformer that can be manufactured, serviced, and scaled across gigawatt-scale campuses.
Define the interface between the SST and the MVDC distribution system, including protection, control boundaries, and fault behavior.
Build a semiconductor and magnetics supply strategy that survives a thin 10kV SiC market over a multi-year horizon.
Develop converter hardware from topology selection through working prototypes on a schedule that data center construction actually depends on.
Select the topology (ISOP DAB stacks, MMC-based, or another approach) and semiconductor strategy, with every choice defended on efficiency, redundancy, manufacturability, and device availability.
Lead the power electronics, magnetics, and controls engineers from architecture to working hardware, owning the technical decisions that get prototypes built rather than debated.
Own the system trade-offs and the interface with the MVDC systems team, writing down exactly where the SST stops and the system begins, precisely enough that both teams can design against it.
Develop a program plan and prototype roadmap, and make the build-vs-partner recommendation honestly, including the case where partnering is the right answer.
Develop vendor and research partnerships across device makers, labs, and universities that secure the devices, test capacity, and expertise the program needs.

Requirements

15+ years in power conversion and experience leading an SST or MV converter program at the level of ABB/Hitachi Energy research, GE, Delta, EPRI, or a FREEDM/ETH/Aachen lineage lab.
Experience in converter topology selection, semiconductor strategy, and system trade-offs at MW scale, and the ability to defend the choices made.
Experience leading converter development teams from architecture through working hardware, not just papers or simulations.
Expertise in the SiC ecosystem, capable of writing a five-year semiconductor strategy in a market where 10kV devices barely exist.
Experience living through a program that died or nearly died, and understanding the reasons behind its failure, along with knowing how to avoid similar issues in the future.
Ability to develop a 12-month program plan for 8 engineers and defend it line by line.

Qualifications

Bachelor's degree in Electrical Engineering or related field.
Master's degree in Electrical Engineering or related field preferred.
Experience with solid-state transformers and MVDC systems.
Experience with semiconductor and magnetics design and supply strategies.
Experience with power electronics, magnetics, and controls engineering.
Experience with medium-frequency transformer design and MVDC system integration.
Experience with vendor and university research partnerships.
Experience with program management and project planning.

Skills

Power conversion and transformer design skills.
Experience with semiconductor and magnetics supply strategies.
System-level design and trade-off analysis.
Project management and program planning skills.
Vendor and research partnership development.
