Location profile: Area Münster

Infrastructure & lifestyle

Area Münster is attractive for many teams because accessibility, infrastructure and quality of life often work well together – useful for workshops, kickoffs and on-site alignment. During high-pressure phases, short distances often translate into real productivity gains.

Technology & engineering ecosystem

Area Münster often stands for an active engineering ecosystem: suppliers, integrators, and hands-on projects where delivery matters. Many initiatives are cross-functional: requirements ↔ architecture ↔ implementation ↔ test – that’s where quality is decided.

Market context

Depending on project demand, Area Münster can offer solid options – from permanent roles to project-based engagements. Clear scope and responsibilities are key. Compensation varies by seniority, domain and accountability – what really matters is demonstrated project impact.

Tasks

• End-to-end development of power electronic assemblies and DC/DC and AC/DC converters for demanding, customer-specific applications, including the medium voltage range.
• Autonomous execution of development projects from the initial concept and feasibility study (e.g., evaluating isolated and non-isolated topologies like DAB, LLC, Buck/Boost) through to series production readiness.
• Detailed design, calculation, and parameter-based simulation (using tools such as LTspice, Matlab/Simulink, Plecs, or Spice) of analog and digital circuits.
• Execution of power loss analyses, thermal simulations, and the conceptualization of protection mechanisms (e.g., to mitigate latent short-circuit risks or overvoltages).
• Practical laboratory testing, hardware bring-up of prototypes, as well as the execution of comprehensive EMC and type testing.
• Technical guidance and mentoring of interdisciplinary, international engineering teams, as well as close collaboration in hardware-software co-design.
• Creation of comprehensive technical specifications and documentation (e.g., E-Plan).

Profile

• Successfully completed degree (Diploma/Master's) in Electrical Engineering, ideally with a focus on Power Electronics, Energy Engineering, or a comparable field.
• Several years of professional experience developing complex power electronics and profound practical knowledge of various converter topologies (e.g., isolated converters, PFC structures).
• Excellent analytical skills along with in-depth expertise in hardware validation and circuit testing (including EMI/EMC measurements, switching-waveform characterization, and environmental testing).
• Confident use of common simulation tools (LTspice, Matlab/Simulink) and sound knowledge in the field of control engineering (e.g., loop tuning) and PCB design.
• Ideally, experience in parameterizing and designing power semiconductors (e.g., MOSFETs) and passive components.
• Fluent German and English skills.
• Strong organizational skills, creativity in developing solutions, structured problem-solving competence, and willingness for occasional domestic and international business travel.

Benefits

• Attractive, market-oriented remuneration package (aligned with collective agreements of the metal and electrical industry) with additional performance bonuses and financial rewards for personal patents or improvement suggestions.
• Excellent work-life balance through flexible working hour models, options for reduced working hours, and attractive mobile work arrangements.
• Tailored career and professional development opportunities via structured development planning, internal academies, technical training, and language courses.
• Comprehensive health management that includes company medical services, health days, company runs, as well as subsidies for fitness programs (such as Hansefit/Wellpass) and bicycle leasing (Eurorad).
• An international working environment with a supportive company climate, long-standing employee tenures, regular team events, and opportunities for global knowledge exchange among colleagues.
