SST Systems Architect, Technical Lead

Fluidstack · San Francisco, CA · 2 mo ago
On-siteEngineering$208k–$263k/yrFull-time

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 methods allow. This role focuses on the Solid-State Transformer (SST) group, which is designing solid-state transformers as a core component of this power architecture.

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 through 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 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 knowledge of why it failed and how to avoid similar issues.
  • Ability to write a 12-month program plan for 8 engineers and defend it line by line.

Qualifications

  • Bachelor's degree in Electrical Engineering or related field.
  • Strong understanding of power electronics, solid-state transformers, and MVDC systems.
  • Experience with semiconductor materials and manufacturing processes.
  • Excellent communication and leadership skills.

Skills

  • Power electronics design and analysis.
  • Solid-state transformer design and development.
  • MVDC system integration and management.
  • Strategic planning and project management.
  • Vendor and research partnership development.

Benefits

  • Competitive compensation range of $208K - $263K.
  • Flexible work arrangements.
  • Continuous learning and professional development opportunities.
  • Health and wellness programs.
  • Work-life balance initiatives.
