# SST Systems Architect, Technical Lead

- **Company:** Fluidstack Ltd
- **Location:** San Francisco, CA, United States
- **Experience:** Expert
- **Contract:** Permanent contract
- **Skills:** Artificial Intelligence, Distributed Systems, Systems Architecture, Systems Integration, Computer Network Operations
- **Published:** November 5, 2026

## About the Role

System Architecture, Technical Leadership, Artificial Intelligence (AI), Network Operations Center, Product Engineering, Supply Chain, Power Engineering, Medium Voltage (MV), Topology, Construction

## Description

* Architect a medium-voltage solid-state transformer that can be manufactured, serviced, and scaled across gigawatt-scale campuses, not just demonstrated in a lab.
 * 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.
 * Take converter hardware from topology selection through working prototypes on a schedule that data center construction actually depends on.

Role Scope

 * 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.

What Were Looking For

The below is a starting point. We always make space for exceptional people, so if you dont fit this role exactly, tell us where you would.

 * You have 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.
 * Youve owned converter topology selection, semiconductor strategy, and system trade-offs at MW scale, and can defend the choices you made.
 * Youve led converter development teams from architecture through working hardware, not just papers or simulations.
 * You know the SiC ecosystem well enough to write a five-year semiconductor strategy in a market where 10kV devices barely exist.
 * Youve lived through a program that died or nearly died, and you know exactly why, and what youd do differently.
 * You can write a 12-month program plan for 8 engineers and defend it line by line.
 * Bonus: medium-frequency transformer design depth, MVDC system integration experience, established vendor and university research relationships, or certification exposure for MV power conversion.
