Arbetsbeskrivning

Ytsab Defence AB is seeking a highly motivated Researcher with a strong background in electromagnetism, power electronics, and experimental laboratory work. Joining our cutting-edge defence R&D team, you will bridge the gap between theoretical physics and advanced engineering.

In this role, you will lead the physical modeling, simulation, and experimental validation of next-generation electromagnetic launch systems. You will be responsible for defining the mathematical frameworks of electromagnetic acceleration, optimizing pulsed-power efficiency, managing extreme thermal/mechanical stresses, and building physical prototypes to validate your models. If you thrive on solving complex multi-physics challenges and want to shape the future of high-velocity propulsion technology, this is your next role.

Key Responsibilities

• Theoretical & Multi-Physics Modeling: Develop fundamental mathematical frameworks combining electromagnetic, thermal, and material physics to describe transient system behaviors and time-varying magnetic forces.
• Simulation: Implement and utilize multi-physics software to simulate large parameter spaces and refine magnetic field dynamics.
• Control & Electrical Subsystems: Define boundary conditions, switching requirements, pulse shapes, and power regulation dependencies for electrical and control subsystems.
• Prototyping & Testing: Design, build, and operate experimental laboratory test setups to evaluate acceleration efficiency and discharge dynamics.
• Reporting & Collaboration: Document test results, prepare technical reports for EU-funded projects, and collaborate closely with multidisciplinary teams of engineers and scientists.

Requirements

• Education: Master's degree or PhD in Applied Physics, Electrical Engineering, Mechatronics, or related field.
• Pulsed Power & Electromagnetic Systems: Strong foundation in electromagnetic acceleration physics and transient magnetic forces, with expertise in pulsed power architectures, high-energy discharge circuits, high-current switching, high-power electronics or electromagnetic propulsion mechanisms.
• Simulation: Experience with multi-physics simulation software (e.g., COMSOL, ANSYS Maxwell, and/or Altair Flux).
• Hands-on Testing: Experience setting up laboratory diagnostics, high-speed data acquisition systems, and working safely with high-voltage hardware.
• Communication & Research: Experience in scientific research and technical report writing, with excellent written and verbal English communication skills (Swedish is a plus).

Bonus Qualifications

• Familiarity with managing thermal dissipation and mechanical stress in high-energy electrical systems.
• Experience in leading technical projects and managing multidisciplinary project deliverables.
• Experience in EU research projects or similar collaborative environments, with strong skills for working alongside external manufacturing and project partners.

What We Offer

• A unique opportunity to work on cutting-edge technologies.
• A flexible and collaborative work environment.
• Possibility to participate in international R&D consortia.
• Competitive salary and benefits.
