MF Development R&D Engineer – Electrical

Stellenbeschreibung:

Do you want to design the magnetic systems powering next-generation energy and industrial solutions?

Noratel is strengthening its advanced R&D capabilities and is looking for an experienced R&D Engineer – Electrical Engineering to join our Medium Frequency (MF) development team.

In this role, you will work on the design and optimization of high-performance transformers and inductors operating in the 5–500 kW range and 2–80 kHz frequency, supporting cutting-edge applications across energy, industrial, and power-electronics systems.

You will be part of a highly skilled engineering environment, working at the intersection of physics, electrical design, and real-world system integration. Collaborating closely with customers and cross‑functional teams, you will help deliver solutions that are not only technically advanced, but also reliable, manufacturable, and cost‑efficient.

Role Purpose

Responsible for the electrical design and simulation of medium‑frequency (MF) magnetic components, including transformers and inductors, that must form, fit, and function correctly within end‑application power systems. The role ensures full electrical compatibility with customer power modules, power‑electronics architectures, and overall system behavior.

This position applies engineering fundamentals, physics‑based modeling, and hands‑on validation to design MF transformers and inductors that operate efficiently, reliably, and predictably within complex power‑electronic systems. The engineer balances performance, stability, manufacturability, and cost, delivering robust MF solutions across 5–500 kW power levels and 2–80 kHz operating frequencies.

Key Responsibilities

1. Electrical & Magnetic Design Ownership

Define electrical and magnetic design parameters for MF transformers and inductive components based on system‑level requirements
Design for efficiency, loss minimization, thermal behavior, insulation coordination, EMI performance, and long‑term reliability
Balance trade‑offs between performance, size, cost, manufacturability, and robustness
Own electrical design decisions from concept through validation, industrialization, and production support

2. Simulation, Modeling & Frequency‑Dependent Behavior

Perform advanced electromagnetic, loss, and thermal simulations using analytical methods and FEM tools
Analyze frequency‑dependent effects such as skin effect, proximity effect, core losses, leakage inductance, parasitics, saturation, and nonlinear behavior
Optimize designs across operating conditions, load profiles, switching strategies, and environmental constraints
Correlate simulation results with prototype testing and production data, refining models as needed
Develop deep understanding of customer power systems, including converter topologies, switching devices, and control methods
Understand interactions between magnetics, power electronics, cooling concepts, and mechanical constraints
Contribute to solution‑level architecture discussions beyond component design
Anticipate and mitigate system‑level risks such as thermal runaway, EMI coupling, and control instability
Select and optimize magnetic core materials (ferrite, nanocrystalline, amorphous, and emerging technologies)
Define winding architectures and conductor technologies (Litz wire, foil, multi‑strand, shaped conductors)
Ensure optimal balance between performance, thermal behavior, insulation integrity, and manufacturability
Collaborate closely with mechanical engineers to ensure system coherence

5. Testing, Validation, DFMEA & Compliance

Define and execute electrical test plans (functional, efficiency, thermal, parasitic, reliability)
Lead or contribute to DFMEA and support PFMEA with manufacturing teams
Validate designs against customer requirements and international standards
Support root‑cause analysis and corrective actions for test or production deviations

6. Manufacturing Support & Cost Optimization

Support DFM/DFA and design‑to‑cost initiatives
Provide critical electrical support during production ramp‑up and serial manufacturing

7. Customer & Cross‑Functional Collaboration

Support customer discussions, clearly explaining design decisions and trade‑offs
Work closely with mechanical engineers, manufacturing, quality, and system architects
Act as an electrical authority within the MF development team

Qualifications & Experience

10+ years of hands‑on experience in magnetics and power electronics, preferably in medium‑frequency or high‑power applications
Strong expertise in transformer and inductor design, loss modeling, and system‑level behavior
Solid understanding of power‑electronic topologies, switching devices, and control strategies
Proven experience with electromagnetic simulation, testing, DFMEA, and validation
Deep knowledge of MF magnetic materials and advanced winding technologies
Engineering degree in Electrical Engineering, Power Electronics, or related field
Practical, hands‑on mindset with strong analytical and problem‑solving skills
Ability to clearly communicate complex technical concepts
Comfortable working at both component and system level
High level of independence, ownership, and motivation
