About The Role
We are building a performance electric two-wheeler from the ground up — our own VCU, BMS, and motor controller software. We are looking for a Model-Based Development (MBD) engineer who will own the controls design layer of that stack: turning functional requirements into executable Simulink/Stateflow models, proving them out in MIL, and handing them to the firmware team in a form they can implement and trust. You will be deciding how the control logic and estimation algorithms actually work and defending those decisions in review.

Key Responsibilities
• Translate functional requirements into models. Take functional requirements for VCU, BMS, and MCU features and build corresponding Simulink / Stateflow / MATLAB models and algorithms— supervisory state machines, mode managers, torque arbitration, thermal derating, charging control, fault handling.
• Do the mathematical modelling. Develop the underlying algorithms and plant models: battery equivalent-circuit models, SOC/SOH estimators, vehicle longitudinal dynamics, motor and drivetrain models, sensor models.



Choose and justify the estimator structure, tuning, and numerical behaviour.
• Own MIL verification end to end. Build test harnesses, author test cases traceable to each requirement, run model coverage (statement / decision / MC-DC), close gaps, and produce the verification evidence. Set up regression suites so model changes don't silently break behaviour.
• Be the bridge to firmware. Walk the firmware team through model intent, data types, fixed-point vs floating-point decisions, execution rates, signal ranges, and interface definitions. Review their implementation against the model. Debug together when bench behaviour diverges from simulation.
• Enforce modelling discipline. Apply and maintain modelling guidelines, reusable libraries, data dictionaries, and version control of models.
• Close the loop with the vehicle. Correlate models against bench, dyno, and on-road data. Re-tune, re-validate,
