Senior Electro-Mechanical Designer

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

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)

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
