HW R&D Engineer

Role & responsibilities

The role encompasses sensors and devices for measuring and monitoring current and voltage (AC and DC) to calculate the resulting energy and all related data in applications for power supply, generation, and distribution, as well as for consumption measurement, including for billing purposes. The R&D Engineer contributes to and owns design modules; the Sr. R&D Engineer leads SBA 53 development projects.

• Design energy meters (MID or non-MID) and current / voltage / power sensing products, from concept to mass production.
• Design sensor hardware, PCB layouts and schematics (OrCAD), often with a focus on analog / digital mixed-signal design.
• Select and design current and voltage sensing solutions using CTs, Hall sensors, shunts and TMR sensors to meet accuracy, isolation and cost targets.
• Apply analog signal processing to develop sophisticated filtering and amplification techniques for accurate data extraction.
• Design microcontroller-based measurement functions ensuring high performance, low power consumption and reliability.
• Use simulation tools (SPICE, MATLAB / Simulink, electromagnetic simulation where required) to model, validate and optimise designs.
• Prototype designs, conduct rigorous testing and calibration to validate performance and refine designs.
• Integrate communication interfaces (wired and/or wireless) for data transmission.
• Ensure compliance with industry standards (EN, IEC, UL, MID, CE, ...).
• Collaborate in international activities relevant for the Division IFT.
• Monitor relevant technological developments in the areas of Sensors and Application-Specific Integrated Circuits (ASIC).

Sr. R&D Engineer additionally: lead project execution, review designs and mentor junior engineers.

Preferred candidate profile

• R&D Engineer: typically 3 to 6 years of relevant experience in electronics design, embedded systems, and high-volume manufacturing.
• Sr. R&D Engineer: typically 6 to 9 years of relevant experience in the same areas, including leading projects.
• Hands-on experience in energy meter design (MID or non-MID), energy measurement and power sensors.
• Experience with CTs, Hall sensors, shunts and TMR sensors for current / magnetic sensing.
• Proficiency in analog and digital circuit design, microcontroller-based hardware, OrCAD, and simulation tools (e.g., SPICE / LTspice, MATLAB/Simulink).
• Experience with communication interfaces and protocols.
