About the role
Role leading end-to-end SST systems architecture and technical leadership for Fluidstack’s power electronics and MVDC integration within gigawatt-scale AI data center infrastructure.
Responsibilities
- Architect the SST end to end, selecting 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.
- Build the 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.
Qualifications
- 15+ years in power conversion and have led an SST or MV converter program at the level of ABB/Hitachi Energy research, GE, Delta, EPRI, or a FREEDM/ETH/Aachen lineage lab.
- Owned converter topology selection, semiconductor strategy, and system trade-offs at MW scale, and can defend the choices you made.
- Led converter development teams from architecture through working hardware, not just papers or simulations.
- Know the SiC ecosystem well enough to write a five-year semiconductor strategy in a market where 10kV devices barely exist.
- Lived through a program that died or nearly died, and you know exactly why, and what you'd do differently.
- Can write a 12-month program plan for 8 engineers and defend it line by line.
