SST Systems Architect, Technical Lead

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 specifically focuses on the Solid-State Transformer (SST) group, which is designing solid-state transformers as a core component of the 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, along with plans for improvement.
• 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.
• Master's degree in Electrical Engineering or related field preferred.
• Experience in power electronics, magnetics, and controls engineering.
• Strong understanding of semiconductor technology and its applications.
• Experience in managing cross-functional teams and projects.
• Excellent communication and leadership skills.

Skills

• Power conversion and transformer design expertise.
• Experience with semiconductor technologies and their integration into power systems.
• Ability to lead complex projects from concept to implementation.
• Strong analytical and problem-solving skills.
• Experience in developing and managing partnerships with vendors and research institutions.

Benefits

• Competitive compensation range of $208K - $263K.
• Flexible work arrangements.
• Continuous professional development opportunities.
• Health and wellness programs.
• Employee referral bonuses.
