What you'll do
- Own the system architecture of the SST and its key performance metrics, including efficiency, power density, cost, thermal performance, reliability, manufacturability and control performance.
- Coordinate the subsystems of the SST (AC/DC, DC/DC, magnetics, mechanical and thermal) and their interfaces, ensuring the work of each team is compatible and consistent with the system design.
- Lead system-level trade-off decisions and set technical priorities across teams.
- Define and maintain system requirements, interface specifications and change management, ensuring design changes are assessed for their impact across the system.
- Translate the requirements of data center operators and hyperscalers into system specifications, and track how they evolve.
- Explore and compare different system architectures and their integration in the datacenter power supply chain.
- Drive standardization and design for manufacturing across subsystems in preparation for series production.
- Work with the compliance and certification team to define a feasible certification path for the system.
- Identify technical risks at system level early and propose mitigations.
What we're looking for
- MSc or a higher degree in Electrical Engineering or a related discipline.
- 8+ years of industry experience in developing complex power electronic systems.
- Proven responsibility at system or platform level, e.g. as system engineer, system architect, technical lead or team lead.
- Track record of taking power electronic systems from development to series product.
- Experience with high-power systems such as EV charging, electric drivetrains, rail traction, industrial drives, renewable energy converters or robotics.
- Broad understanding of the electrical, magnetic, thermal, mechanical and control aspects of power electronic systems, and how they interact.
- Working knowledge of cooling concepts and the mechanical integration of high-power electronics.
- Experience with standards, norms and certification processes for power electronic products.
- Strong communication and decision-making skills; able to align experts across disciplines and drive decisions.
- Comfortable working in a fast-paced startup environment with evolving requirements.
Nice to have
- Experience with medium-voltage converter systems or solid-state transformers.
- Knowledge of data center power architectures.
- Experience in design for manufacturing and cost engineering.
- Experience establishing systems engineering processes in a growing organization.
Benefits
- Equity + competitive salary.
- Unique technology and market opportunity – shape the architecture of a new product category for the energy transition.
- Hybrid work with flexible working times.
