Job summary

Arbor Mobility in Bengaluru, India, seeks a Model Based Development Engineer to own the controls design layer of the EV stack, turning requirements into executable Simulink/Stateflow models and proving them in MIL. You will defend decisions in reviews and collaborate with firmware to ensure correct implementation.

The role requires deep Simulink/Stateflow expertise, strong math, and experience with vehicle control algorithms, estimation, and model-based development in a fast-growing EV startup.

Qualifications

• Requires 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 preferred.
• Deep hands-on experience with Simulink, Stateflow, and MATLAB; proven model shipping.
• Strong foundation in state-space, control theory, estimation, and numerical stability.

Responsibilities

• Translate functional requirements into models for VCU, BMS, and MCU features.
• Develop battery SOC/SOH estimators and vehicle dynamics models.
• Own MIL verification end-to-end with test harnesses and coverage analysis.
• Bridge models to firmware; review implementations with fixed-point vs floating-point decisions.
• Maintain modelling guidelines, libraries, data dictionaries, and version control.
• Correlate models with bench, dyno, and on-road data; re-tune as needed.

Job description

Model Based Development Engineer- Vehicle Control Software

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.

What you'll do

• 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.
• 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

• 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), coulomb counting with OCV correction, equivalent-circuit or electrochemical models, parameter identification from cell test data, SOP/power-limit estimation; or FOC motor control — PMSM/BLDC field-oriented control, Clarke/Park transforms, current and speed loop design, field weakening, MTPA, sensorless position estimation or resolver/encoder handling, PWM and inverter modelling.
• Requirements-driven mindset. Comfortable working from formal functional requirements and maintaining bidirectional traceability from requirement to model to test.
• Clear technical communication. You can explain a filter, a state machine, or a derating curve to a firmware engineer well enough that they can implement it correctly without you in the room.

Good to have

• Auto-code generation experience (Embedded Coder, TargetLink) and fixed-point design.
• Functional safety exposure — ISO 26262, safety requirements decomposition, ASIL-rated functions, safe-state design.
• Python or MATLAB scripting for test automation and data post-processing.
• HIL / SIL experience (dSPACE, Speedgoat, Typhoon, PLECS, or custom rigs).
• Simulink Test, Simulink Coverage, Simulink Design Verifier, Polyspace.
• CAN / CAN-FD, UDS diagnostics, and vehicle network architecture familiarity.
• Git-based workflows for models; experience with model merge/diff.
• Prior work on two-wheeler EVs, BMS hardware bring-up, or inverter development.
