Grid Systems Engineer

Job Description

Hyperscale Power is building the power backbone for the AI data center era: a complete power conversion chain from 13.8kV–35kV medium-voltage AC down to 800V DC, combining ultra-compact SiC-based AC/DC and DC/DC power blocks. The grid interconnection is where our system meets the utility – getting it right is fundamental to a safe, compliant and reliable product across every market we serve.

As Grid Systems Engineer, you will design and develop the medium-voltage grid interconnection aspects of our power conversion system – from prototype construction and checkout through certification and volume production. You will work closely with the Power Electronics, Firmware and Test & Field teams, and with our external test & certification partners, to ensure our systems meet grid codes and interconnection requirements across our target markets.

It is a unique opportunity to shape the grid interface of a breakthrough power electronics platform from an early stage – with direct visibility to the CTO and engineering leadership.

Key Responsibilities

• Design and develop the medium-voltage (13.8kV–35kV) grid interconnection system and related electromechanical/electronic equipment; prepare related installation, operation and maintenance specifications and instructions.

• Analyze equipment to establish operating data and conduct experimental tests on grid-interface hardware (transformers, protection, switchgear interfaces) under realistic grid conditions.

• Analyze engineering proposals and technical data to determine the feasibility of new equipment or modifications to existing designs for different grid voltage levels and markets.

• Responsible for prototype construction and checkout of grid-interconnection subsystems, supporting our Prototype and Alpha Customer milestones.

• Compile operational data and prepare customer application information and documentation for grid-tied deployments.

• Ensure compliance with grid codes, interconnection standards and utility requirements (e.g., IEEE 519, IEEE 1547, IEC 61850, UL 1741) and support certification processes together with our test & certification partners (UL, TÜV, IEC 62477).

• Collaborate with the Power Electronics and Firmware teams on protection coordination, fault ride-through, and control strategies for grid-tied operation.

• Respond to customer and partner technical requests regarding grid interconnection requirements as they occur.

• Support scaling of the grid-interface design across different grid codes and markets as we move from Alpha Customer readiness to Production and Volume Readiness.

Qualifications

• BSc / MSc in electrical engineering, power systems engineering or comparable education.

• Experience in medium-voltage grid interconnection, power systems, or utility-scale grid-tied power electronics (e.g. solar/wind/BESS inverters, solid-state transformers) preferred.

• Familiarity with grid codes and interconnection standards (e.g. IEEE 519, IEEE 1547, IEC 61850, IEC 61400, IEC 62933, VDE-AR-N, UL 1741).

• Hands-on experience with prototype build, checkout and test of electromechanical/electronic equipment.

• Strong analytical skills; comfortable designing and running experimental tests, analyzing the resulting data, and documenting the results.

• Team player, comfortable engaging directly with customers and partners on technical requirements.

• Language skills: fluent in English, spoken and written; German language skills helpful, but not mandatory.

• The job will be located at our HQ in Egg b. Zürich in Switzerland. National and international willingness to travel is assumed.

Benefits

• Equity + competitive salary.

• Unique technology and market opportunity – validated prototype and first paying customers on the path to volume shipments.

• Hybrid work with flexible working times.
