Job summary

TVS Motor in Bengaluru seeks a senior powertrain engineer responsible for sizing, system integration and performance analysis of powertrain components. You will translate vehicle targets into motor, inverter, battery, transmission and thermal specs, build sizing models, and conduct trade-off studies.

You will coordinate across stakeholders, define system requirements, manage interfaces, run simulations, and support testing, homologation, and DVP planning to ensure robust powertrain architectures

Responsibilities

• Translate vehicle targets into motor, inverter, battery, transmission and thermal system specs.
• Build and maintain powertrain sizing models: road load, tractive effort, envelopes, gear ratios, and battery sizing.
• Perform trade-off studies (efficiency vs cost vs weight vs packaging) for architecture and sourcing decisions.
• Define and document powertrain operating limits: power, current, voltage, temperature across ambient and SOC.
• Coordinate with component owners for powertrain delivery at each program gate; create system docs (DFMEA, FTA, QC stories).
• Derive and cascade powertrain requirements from vehicle, regulatory, safety and customer needs.
• Maintain baseline, versioning and traceability in the requirements tool.
• Manage change impact analysis across components, suppliers and validation plans.
• Define and control powertrain interfaces: mounting, cooling, HV/LV packaging, diagnosis.
• Maintain interface control documents and resolve conflicts between motor, inverter, battery, charger, transmission and vehicle.
• Own thermal integration: cooling architecture, flow, heat rejection budgets and derating at system level.
• Support packaging, weight and cost tracking with vehicle integration and design.
• Produce and maintain system specs, architecture docs, integration reports and gate packages.
• Contribute to ISO 26262 item definition, HARA and powertrain safety concept; verify requirements.
• Build and correlate vehicle and powertrain models (MATLAB/Simulink) for performance and range. Coordinate with simulation team for details.
• Create real-use drive cycles from field data and targets.
• Predict and verify cycle performance (WMTC, IDC/MIDC, WLTC); track range and consumption budgets.
• Own energy and loss budget: motor, inverter, battery, transmission, auxiliaries and thermal losses; drive efficiency actions.
• Correlate simulation with dyno and vehicle data; maintain accuracy and confidence.
• Benchmark competitor powertrains and feed findings into targets and roadmaps.
• Define and execute powertrain DVP: tests across bench, dyno, environmental, durability and vehicle level.
• Analyze test data, judge compliance, document deviations and drive countermeasures to closure.
• Support homologation and certification with data, calculations and test evidence.
• Capture lessons learned; maintain reusable sizing methods, templates and guidelines.

Job description

Role Description

\"Accountability: Powertrain Sizing and Dimensioning

• Translate vehicle attribute targets (top speed, acceleration, gradeability, range, payload, duty cycle) into motor, inverter, battery, transmission and thermal system specifications.


• Build and maintain the powertrain sizing models: road load, tractive effort, motor and inverter operating envelopes, gear ratio selection and battery energy/power sizing.


• Perform trade-off and sensitivity studies (efficiency vs cost vs weight vs packaging) and produce the technical basis for architecture and sourcing decisions.


• Define, maintain and document the powertrain operating limits: continuous and peak power, current, voltage and temperature envelopes across ambient and state-of-charge conditions.

\"Accountability: Powertrain delivery, System Requirements Engineering and Traceability

• Coordinate across all component owners and stakeholders for the delivery of the powertrain with the expected maturity at each program gate (create system level documentation like DFMEA, FTA, QC stories and support component level deliverable).


• Derive powertrain system requirements from vehicle, regulatory, safety and customer requirements and cascade them to component specifications.


• Maintain the requirement baseline, versioning and bidirectional traceability in the requirements management tool.


• Manage change impact analysis across components, suppliers and validation plans.

\"Accountability: System Integration and Interface Management

• Define and control the powertrain interfaces: mechanical mounting and cooling, HV and LV electrical packaging, diagnosis, etc.


• Maintain interface control documents and resolve integration conflicts between motor, inverter, battery, charger, transmission, thermal system and vehicle.


• Own the powertrain thermal integration concept: cooling architecture, flow and heat rejection budgets and thermal derating behaviour at system level.


• Support packaging, weight and cost tracking of the powertrain together with vehicle integration and mechanical design.


• Produce and maintain system specifications, architecture descriptions, integration reports and gate review packages.


• Contribute to the ISO 26262 item definition, HARA and system-level safety concept for the powertrain and verify the derived safety requirements.

\"Accountability: Vehicle and Powertrain Performance Analysis and Benchmarking

• Build and correlate vehicle and powertrain simulation models (MATLAB-Simulink) for performance, energy consumption and range prediction. Coordinate with the advanced simulation team for more detailed simulations if required.


• Create real-use drive cycles from field data and vehicle targets.


• Predict and verify certification and real-world cycle performance (WMTC, IDC/MIDC, WLTC and customer duty cycles) and track the range/consumption budget through the programme.


• Own the powertrain energy and loss budget: motor, inverter, battery, transmission, auxiliaries and thermal losses; drive efficiency improvement actions.


• Correlate simulation against dyno and vehicle measurement and maintain model accuracy and confidence statements.


• Benchmark competitor powertrains and technologies and feed the findings into target setting and architecture roadmaps.

\"Accountability: Powertrain System DVP Planning and Execution and Homologation

• Define and execute the powertrain DVP: analysis, bench, dyno, environmental, durability and vehicle-level tests with acceptance criteria linked to requirements.


• Analyse test data, judge requirement compliance, document deviations and drive design or calibration countermeasures to closure.


• Support homologation and certification activities with the required technical data, calculations and test evidence.


• Capture lessons learned and maintain reusable sizing methods, calculation templates and design guidelines.
