Electrical Engineer

Doubling the speed and precision of high-tech infrastructure like semiconductor equipment

About Fluxthor

Fluxthor is a TU Delft spinoff building the first commercially available reluctance actuators. A new category of magnetic actuation that breaks the force-density and efficiency limits of conventional actuating principles. More force from a smaller, more efficient, lighter package, exactly where the most demanding systems need it: faster stage settling times in advanced positioning stages in semiconductor equipment, higher-bandwidth fast steering mirrors and nanometer alignment in optics, and viable precision actuation in space where every watt and gram counts. We're commercializing patented technology out of TU Delft, backed by deep-tech investors, building the actuation infrastructure layer for the next decades of high-tech systems.

The Role

We’re looking for a hands-on, technically curious Electronics Engineer to join us! You’ll work directly with the founding team to bring our core technology from the lab to market. Expect to design, build, and test new power electronics, instrumentation and motion controllers, from the initial prototypes up to production and testing. This is a full-stack electronics role in a fast-paced, high-ownership environment, with direct influence on design decisions, product roadmap, and technical direction.

What You’ll Do

Design, build, and test power electronics and motion controllers for driving reluctance actuators — from initial prototypes to production-ready hardware

Develop and iterate on PCB designs for coil drivers, instrumentation amplifiers, signal processing circuits, and microcontroller architecture

Build instrumentation setups to characterize actuator performance (force, displacement, thermal, bandwidth, flux etc.)

Assist in sensor selection in collaboration with mechanical engineers to fit electronics needs of motor drivers.

Own the full electronics development cycle: schematic capture, PCB layout, bring-up, debugging, and validation

Write clean scripts for automated testing and data acquisition

Contribute to defining electronics architecture decisions that shape the product roadmap

Work closely with the founding team on translating customer requirements into technical specifications

What We’re Looking For

MSc or BSc in Electrical Engineering, Embedded Systems or System & Control

Eager to learn and ready to take full ownership of projects in a startup environment

Team-oriented and communicative and you like working together at the office

Hands‑on mindset: you enjoy designing, building, testing and iterating

Experience with drawing electronics schematics and PCB designs in programs like EasyEDA, kiCad, or Altium

Comfortable writing clean C/C++ and Python code for embedded systems and experimental evaluation

Candidates must be legally permitted to work in the Netherlands; we are unable to provide visa or work permit sponsorship.

Bonus Points

2+ years of experience in design power electronics, instrumentation setups and controller architectures.

Take the lead on the domain of electrical engineering within the company

Interested in electromagnetic physics on the electrical side and how this translates to dynamics.

What We Offer

€3.500 - €4.500 salary range that matches your experience and skill level, including 8% vacation allowance

28 days of vacation

A front-row seat in a high-impact startup bringing new physics into the world of precision motion

Close collaboration with a highly driven, technical founding team

Office space at YES!Delft, surrounded by a vibrant startup ecosystem with events

Opportunity to be listed as co-inventor on new patent filings
