storage, and traction motor drives. This is a hands-on lead role: you'll set the control
strategy, architect and build the models with engineers, guide engineers on the firmware that
ships, and sit in the lab when things don't behave the way the model said it would.
We're deliberately hiring one person across all four product lines rather than siloing them,
because the control fundamentals are shared and are scalable across different products.
Responsibilities:
● Own closed-loop control design end to end - plant modelling, loop shaping, digital
compensator design, and discrete-time implementation - for PFC stages, isolated
DC-DC, grid-tied inverters, and FOC motor drives
● Build and maintain averaged and switching models in MATLAB/Simulink (plus
PLECS or Simscape Electrical), and drive them through MIL, SIL, PIL and HIL
validation before hardware exists
● Implement control loops in embedded C on real-time targets, at ISR level, with
correct PWM/ADC synchronisation, deadtime compensation, and fault handling
● Design grid-interface control for bidirectional PCS: PLL and synchronisation,
resonant or repetitive current control, droop and grid-forming modes, ride-through
and anti-islanding
● Define and execute the controls validation plan - stability margins across operating
envelope, transient response, weak-grid and impedance-based stability, efficiency
and THD verification
● Work directly with magnetics, PCB layout, thermal and EMC engineers, because a
control loop that ignores parasitics, sensing delay and switching noise is a simulation,
not a product
● Set the standards the rest of the team works to: modelling conventions, autocode
practice, code review, and how control requirements trace to test evidence
● Mentor group of engineers and raise the team's depth in control theory and hardware
design.Essential Skills:
● M.tech/PhD in Electrical, Power Electronics, Control Systems (Bachelor's in
Electrical).
● 8+ years in power electronics controls, with at least two of the four domains shipped
to production
● Genuine control systems fundamentals - state-space averaging, small-signal
modelling, loop shaping, discretisation effects, sampling and computational delay,
digital redesign. You should be able to derive a compensator, not only tune one
● Strong MATLAB/Simulink, including model-based design workflow and at least one
real HIL toolchain (dSPACE, Typhoon HIL, OPAL-RT, Speedgoat)
● Production embedded C on a real-time control MCU or DSP - TI C2000, Infineon
AURIX or XMC, STM32G4/H7, or equivalent. Comfortable with fixed-point and
floating-point trade-offs and with what actually fits in a 50 kHz ISR
● Lab competence: you can drive a scope, a power analyser and an electronic load,
and you trust measurements over models when they disagree
● Working knowledge of the standards that constrain these products - IEC 61851,
ISO 15118, CISPR 25 or CISPR 11, IEC 61000, and for grid-tied work IEEE 1547 or
the relevant regional grid code
Nice to have
● Wide bandgap experience - GaN totem-pole PFC or SiC traction inverters
● Bidirectional topologies: CLLC, dual active bridge, four-quadrant PCS
● Sensorless motor control, observer design, MTPA and field weakening
● Functional safety exposure - ISO 26262 or IEC 61508
● Production autocode via Embedded Coder into a safety-relevant build
