Model-Based Development Engineer (Vehicle / Battery Control Software)

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, and keep the model the source of truth as the vehicle matures. • Support the path to SIL/HIL as our test infrastructure builds out, and contribute to code-generation workflows where we adopt them. Requirements Required • B.E./B.Tech/M.Tech in Electrical, Electronics, Mechanical, Instrumentation, Control Systems, or equivalent. • 3–5 years of automotive experience in model-based development. EV experience strongly preferred. • Deep hands-on Simulink, Stateflow, and MATLAB. You have personally built and shipped models, not just maintained someone else's. • Strong mathematical foundation — state-space representation, control theory (PI/PID, feedforward, anti-windup, gain scheduling), estimation and filtering, linear algebra, discretisation and numerical stability. You should be able to derive an algorithm on a whiteboard, not just wire up a block diagram. • One of the following is mandatory: ◦ Battery estimation algorithms — SOC/SOH estimation using Kalman-family filters (EKF/UKF),…
