OM Defence Systems builds technology that operates where it matters most — at the edge of security, complexity, and consequence. Our teams design and integrate systems for clients who cannot afford failure.
We move fast, think rigorously, and take full ownership of what we build.

ABOUT THE ROLE
OM Motors develops high-efficiency BLDC motors for heavy-lift industrial multirotor platforms. We are looking for an engineer with deep expertise in electromagnetic design, capable of independently managing the full development cycle — from motor-to-propeller system matching through to series production. Team working language is English.
RESPONSIBILITIES
- Motor-to-propeller system matching: KV selection, operating point calculation, topology and slot/pole scheme
- FEA model development and verification (Maxwell, JMAG, FEMM, MotorCAD)
- Winding design: wire cross-section, fill factor, R_phase, L_d/L_q, Litz wire for high electrical frequencies
- Thermal analysis: LPTN models, cooling strategy selection, insulation class verification
- PWM harmonic loss analysis, cogging torque optimisation
- Dynamometer testing: back-EMF characterisation, efficiency mapping, thermal run
- Production support and supplier management
REQUIREMENTS
- 5+ years of BLDC / PMSM design experience
- Hands-on experience with FEA tools: Maxwell, JMAG or FEMM
- Knowledge of winding factor, Bertotti loss model, demagnetisation analysis
- EM design of outrunner SPM/IPM topologies, field weakening, CPSR
- Python or MATLAB for calculation automation
- Familiarity with IEC 60034, IEC 60085, IP55
- Fluent English (working language)
NICE TO HAVE
- Experience with UAV / drone motors
- MotorCAD, CFD, multi-objective optimisation (NSGA-II)
- Experience with axial flux machines (AFPM)
- Experience working with Chinese manufacturers
CONDITIONS
- Fully remote position
- Real products for heavy-lift cargo aviation — not a research project
- Direct involvement in design decisions from day one
- Competitive compensation, discussed individually
