Your mission

As our technical lead for electric motors, you take full ownership of the custom BLDC and stepper motors that drive our space equipment: motorized valves and pressure regulators, pumps and compressors, and potentially actuators for robotic mechanisms. You take them from first-principles sizing through hands-on testing in our Munich lab to flight qualification.

In detail you will:

Technical Ownership: Act as deltaVision’s subject-matter expert for electric machines. Define motor topologies, drive design decisions with Design-to-Cost in mind and build up our long-term motor know-how.
Electromagnetic & Thermal Sizing: Size BLDC and precision stepper motors from first principles and with numerical tools, from magnetic circuit and slot/pole selection to winding design and thermal budget. Turn repeated calculations into Python sizing tools.
Extreme-Environment Design: Adapt motors to cryogenic temperatures and vacuum: magnetic material behaviour at low temperature, insulation integrity, cryogenic bearing lubrication and heat rejection without convection.
Integrated Actuation: Package frameless stators and rotors directly into valve bodies, pump housings and mechanisms with our mechanical, systems and fluid engineers, and define drive and sensing requirements with our electronics team.
Build & Process: Drive prototype builds with external winding and manufacturing partners and in-house (assembly, potting, sub-components), then turn what works into a controlled, repeatable process.
Test & Qualification: Write test procedures and characterize your motors in our lab (back-EMF, cogging torque, torque-speed curves, step accuracy) through to qualification under cryogenic and vacuum conditions.

Your profile

Degree in Electrical Engineering, Mechatronics, Mechanical or Aerospace Engineering or a related field, with a specialization in electrical machines.
3+ years of engineering experience in the electromagnetic and mechanical design of electric motors, ideally BLDC and stepper, including frameless and flanged configurations for integrated actuators.
Hands-on experience with motor sizing and simulation tools (e.g. Motor-CAD, MotorXP, Ansys Maxwell, JMAG, FEMM) or your own Python-based analytical models.
Good understanding of motor commutation, position sensing (Hall, resolver, encoder) and stepper drive behaviour.
Practical knowledge of motor manufacturing: laminations, custom windings, magnet retention and bonding, insulation classes, encapsulation and process control.
A hands-on mindset is mandatory: you inspect, assemble and troubleshoot hardware on the bench yourself, not only in simulation.
Motivated, pragmatic and self-organized. You prefer “done” over “perfect on paper” and lead motor development independently across teams.
Fluency in English; German is a plus.

What would make you stand out:

Experience with motors or actuators for space, aerospace or other extreme environments (cryogenics, vacuum outgassing, vibration)
Experience with motors or bearings operating at cryogenic temperatures
Familiarity with motor drive electronics (e.g. field-oriented control, microstepping) and controller testing
Experience with ECSS or comparable qualification frameworks

About us

We are deltaVision GmbH – a young, ambitious high-tech company based in Munich, driving the future of in-space mobility and infrastructure.

Since our founding in 2022, we have been developing, manufacturing, and qualifying advanced fluid control systems for the aerospace industry and H₂ aviation. Our expertise spans cryogenic and high-pressure propulsion systems as well as next-generation orbital refueling technologies, including couplers and fully integrated refueling systems designed for the harsh environment of space.

With our deep knowledge of fluid control for space systems, we are shaping the space economy towards refuelable and reusable spacecraft. We enable longer mission lifetimes, greater operational flexibility, and entirely new architectures for sustainable space operations.

What sets us apart?

Innovative products enabling next-generation space infrastructure
Exceptional cost efficiency through optimized design and manufacturing
Rapid development and delivery cycles beyond traditional industry standards

We are rethinking spaceflight — enabling a future where spacecraft are not disposable, but reusable, refuelable, and built to operate sustainably in orbit.
