Job description

Senior Controls Engineer

We're looking for a Senior Controls Engineer to take technical ownership of advanced control algorithms for high-performance electromechanical systems for a UK defence start up.

The initial focus will be motor control and Field-Oriented Control (FOC), working closely with embedded software and electronic hardware engineers to develop production-ready control algorithms from first principles. Over time, the scope will broaden into more complex servo, motion and multi-axis control applications.

Skills & Experience

Essential:

• Strong practical Field-Oriented Control (FOC) experience
• First-principles plant modelling and control system design
• MATLAB / Simulink and Model-Based Design
• Experience developing models suitable for automatic code generation
• System identification and parameter estimation using real test data
• Experience taking control algorithms through to production or qualified prototype
• Strong hands‑on testing, instrumentation and control system debugging
• Ability to work closely with embedded firmware and electronic hardware teams
• SC Eligibility (Dual British & NATO nationalities considered)
• Servo / motion control, including position, velocity and current loops
• Trajectory generation and multi‑axis control
• Sensorless motor control and observer design
• Kalman filtering or other state‑estimation techniques
• Hardware-in-the-Loop (HIL) development and validation
• Encoders, resolvers, Hall sensors and other position/speed sensing technologies
• Real‑time embedded control implementation
• Experience with complex dynamic systems such as robotics, aerospace, automotive or other high‑performance applications
• Comfortable operating in a less strcutured environment

Additional Information

• Permanent, full‑time position
• Competitive salary depending on experience
• Reading based, onsite
• Senior individual‑contributor position with significant technical ownership
• Hands‑on role spanning modelling, algorithm development and physical system validation
• Scope to work on increasingly complex control and electromechanical systems
