Electrical Engineer (80–100%)

Location: Solothurn · Workload: 80–100% · Start date: to be agreed upon · Permanent position

Your Role

You’ll join our technical team and take independent responsibility for integrating inverter technologies into our energy storage systems—from design and parameterization to commissioning. You’ll develop technical solutions for complex customer projects. At the same time, you’ll serve as the technical liaison to our software development team: you’ll advise the team on the gateway platform, define requirements based on real-world experience, and validate new features on the actual system. Your work is varied, technically challenging, and has a direct impact: you’ll be driving the energy transition forward.

Your Responsibilities

  • Inverter Integration: Design, parameterization, and commissioning of hybrid and
    battery inverters in conjunction with our sodium-ion storage systems (AC and
    DC coupling, grid-connected systems).

  • Technical Solution Concepts: Development of solution approaches for complex projects —
    Grid connection, protection and safety concepts, compliance with standards (NIN, plant regulations,
    NA protection).

  • Protocol Integration: Connecting internal components and external EMS systems via Modbus
    RTU/TCP, MQTT, and other common protocols.

  • Software Development Interface: Consulting and assistance with the further development of the
    gateway platform—incorporating requirements from the field, clarifying driver and protocol issues
    , and testing new releases on the lab system.

  • Designing, conducting, and automating tests: test benches in the lab, measurements on cells,
    modules, and complete systems—often executed and evaluated using scripts (Bash,
    Python).

  • On-site Debugging and Second-Level Support: Handling escalations from Support —
    Analyzing and reproducing problems and developing solutions, including on-site visits to
    customers when necessary.

  • Schematic and BOM Verification: Verify schematics, reconcile BOMs against schematics,
    identify and correct inconsistencies.

  • Documentation: Record technical concepts, test reports, and commissioning logs in such a way th
    , they can be used by customers, regulatory agencies, and for internal reviews.

What You Bring to the Table 

  • Completed degree in electrical engineering, energy engineering, mechatronics, or embedded
    systems—Bachelor’s degree from a university of applied sciences or university, certified technician (HF), or equivalent continuing education based
    on a vocational apprenticeship (e.g., automation technician, electronics technician, or electrical installer EFZ)

  • A solid understanding of power electronics, ideally with hands-on experience with
    inverters, battery systems, or photovoltaics

  • Experience with communication protocols such as Modbus RTU/TCP; MQTT is a plus

  • Proficiency in Linux (configuration, shell, package management) and at least one
    scripting language—Bash and/or Python

  • Be able to reliably read, review, and verify the accuracy of circuit diagrams and bills of materials

  • Hands-on practice with measurement equipment (multimeters, oscilloscopes, current clamps, data loggers)

  • Knowledge of the NIN and initial exposure to grid connection topics (plant regulations,
    grid connection protection) is a plus

  • An independent, structured approach to work; an analytical approach to troubleshooting; and a passion for bridging the gap between hardware and software

  • Business-level German, good English (data sheets, technical communication);

  • Category B Driver's License for Field Operations

What We Offer

  • Independent tasks with real creative freedom—in a small team,
    your work is immediately visible

  • Quick decision-making processes, flat hierarchies, and a direct mentor from the technical
    management team

  • Responsibility throughout the entire product life cycle: design, testing, commissioning,
    after-sales service

  • Laboratory equipped with state-of-the-art measurement and data storage technology

  • Flexible work hours, fair compensation, and clear career advancement opportunities in a growing
    product environment
