Job description

We are looking for a Senior Electro-Mechanical Designer with focus on Power Electronics Cabinet Designer with a strong system‑level understanding of power electronics, electrical architecture, and 3D cabinet design for semiconductor and defense applications. This role focuses on the architectural and detailed design of power modules and power cabinets used in high‑reliability, safety‑critical environments.

The ideal candidate combines deep electrical knowledge with hands‑on cabinet and enclosure design experience, ensuring full compliance with industry standards while optimizing performance, EMC behavior, thermal management, and manufacturability.

Key Responsibilities

Power Electronics & System Architecture

  • Architectural design thinking for power electronic cabinets and power modules in medium- to high-power systems, defining overall cabinet architecture including segmentation, redundancy concepts, safety zoning, and serviceability

  • Design power distribution schemes, protection concepts, grounding strategies, and isolation boundaries

  • Translate electrical schematics into optimized physical cabinet layouts

  • Collaborate with power electronics engineers on converter topology, power stages, auxiliary supplies, sensing, and control

Cabinet Design & Mechanical Integration

  • Design complete electrical cabinets and enclosures, including frames, panels, mounting plates, brackets, and covers

  • Integrate power electronics components such as converters, transformers, filters, reactors, busbars, contactors, breakers, and sensors

  • Define robust cable routing, harnessing, strain relief, and connector concepts for power, signal, and communication wiring

  • Coordinate and support thermal management concepts, including air cooling and liquid cooling solutions

EMC, Shielding & Grounding

  • Design cabinets with strong focus on EMC/EMI compliance, including noise mitigation, filtering, shielding, and segregation

  • Define and implement shielding concepts, bonding strategies, and enclosure interfaces

  • Develop and apply grounding and earthing concepts suitable for high‑power, high‑frequency, and safety‑critical systems

  • Work closely with system and EMC engineers to ensure compliance during design and validation phases

Standards & Compliance

  • Design in accordance with semiconductor and defense industry standards, as well as applicable international electrical standards

  • Ensure compliance with IEC, UL, CE, and relevant defense or customer‑specific requirements

  • Apply best practices for functional safety, reliability, and lifecycle management

  • Support design reviews, technical audits, risk analysis, and FMEA activities

3D Design & Electrical Documentation

  • Develop detailed 3D designs and assemblies using professional CAD tools, with a strong preference for Siemens NX; experience with SolidWorks, Creo, Inventor, or CATIA is also acceptable

  • Create and maintain electrical schematics using EPLAN (P8 preferred)

  • Produce complete documentation packages, including: 

  • Electrical schematics and wiring diagrams

  • Cabinet layouts and assembly drawings

  • Cable routing and harness documentation

  • Bills of materials (BOMs)

  • Manufacturing, installation, and service documentation

Collaboration & Technical Leadership

  • Act as a senior technical authority in cabinet and power system design

  • Mentor junior engineers and designers and contribute to design guidelines and best practices

  • Collaborate with multidisciplinary teams including electrical, mechanical, system, manufacturing, quality, and test engineering

  • Support suppliers and manufacturing during prototyping and series production

What We Offer

  • Challenging projects in semiconductor and defense industries

  • High level of technical ownership and influence on system architecture

  • Collaborative, engineering‑driven culture

  • Competitive compensation and long‑term growth opportunities

Job requirements

Education

  • Bachelor’s or Master’s degree in Electrical Engineering, Power Electronics, Mechatronics, or equivalent practical experience

Experience

  • Typically 8+ years of experience in power electronics cabinet or system design

  • Proven experience designing power cabinets and power modules for industrial, semiconductor, or defense environments 

Technical Skills

  • Strong understanding of power electronics and electrical system architecture

  • Solid knowledge of: 

  • EMC / EMI principles

  • Shielding, bonding, and grounding concepts

  • Electrical safety and isolation

  • Thermal design considerations

  • High‑voltage and/or high‑current systems

  • Hands‑on experience with EPLAN or Similar softwares

  • Advanced experience with 3D CAD tools, preferably Siemens NX

Standards Knowledge

  • Familiarity with semiconductor equipment standards and defense‑related standards

  • Strong understanding of international electrical standards (IEC, UL, CE, etc.)

  • Experience working in regulated, documentation‑driven environments

Soft Skills 

  • Strong system‑level and analytical thinking

  • High attention to detail and structured approach to design

  • Clear technical communication skills

  • Ability to work independently and take ownership of complex design topics

Nice to Have 

  • Experience with liquid‑cooled power electronics

  • Busbar design and optimization experience

  • Experience with customer or certification authority interactions

  • Familiarity with configuration management and controlled documentation systems
