Fluxthor is a TU Delft spinoff developing a new category of magnetic actuators. Unlike conventional actuators that rely on Lorentz force, we create actuators using the reluctance principle. This means our actuators radically improve in force-density and energy-efficiency, enabling new levels of precision and speed. This is crucial for applications in semiconductors equipment or optics where systems demands are ever increasing. We're based at YES!Delft and backed by deep-tech investors.
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.
Tasks
- 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
Requirements
- 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
- 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.
Benefits
- Market conform salary that matches your experience and skill level
- 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
Reach out or apply directly! We’d love to hear from you.
