Inverter Software Controls Engineer

At Tata Technologies we make product development dreams a reality by designing, engineering and validating the products of tomorrow for the world’s leading manufacturers. Due to our continued growth, we are now recruiting for a Invertors Software Control Engineer. to be based at our customer’s site in Gaydon

Our Embedded Systems Solutions department (ESS) encompasses all activities outlined under the Automotive SPICE (ASPICE) process framework, including systems engineering, software engineering, coding, and all levels of functional testing. Beyond core development, ESS also integrates critical supporting processes such as project management, risk assessment, functional safety, and cybersecurity, ensuring compliance with ASPICE standards and delivering reliable, secure, and high-quality embedded systems & solutions.

The Role:

We are looking for a highly skilled and hands-on Software & Controls Engineer to develop and implement motor control algorithms, including Field-Oriented Control (FOC) and Current Control, for automotive inverter systems. This role demands deep understanding of Electric Machine (EM) behavior, control theory, and embedded implementation within an AUTOSAR environment running on Infineon Aurix microcontrollers in production-grade platforms.

Area of Responsibility 

• Design and implement FOC, current control, PWM generation, and torque modulation algorithms for various inverter topologies.


• Integrate EM control logic into automotive-grade AUTOSAR environments, including software component definition and configuration.


• Optimize control strategies for performance, safety, efficiency, and NVH behavior across different drive modes.

• Develop embedded software in C/C++, tailored for Aurix TC3xx/TC4xx microcontroller platforms.


• Configure and manage AUTOSAR BSW/MCAL stacks, including RTE mappings, I/O drivers, and real-time scheduling.


• Ensure compliance with ISO 26262 functional safety requirements, including safety mechanism integration and fault response control.

• Collaborate with HIL and dyno teams to validate control algorithms under closed-loop simulation and bench conditions.


• Develop and refine diagnostic strategies for EM/inverter faults including overcurrent, desaturation, and thermal limit protections.


• Support calibration, debugging, and tuning of inverter controls during integration and vehicle testing.

• Interface with system engineers, functional safety teams, and Tier-1 suppliers for requirement alignment and architecture integration.


• Document control models, configuration files, and compliance evidence for internal and OEM milestone reviews.


• Participate in software quality processes including ASPICE audits and peer code reviews.

Knowledge / Experience

Essential

• Experience in EM control development for automotive inverter systems.


• Strong experience with Field-Oriented Control (FOC), current control loops, and motor parameter estimation techniques.


• Hands-on proficiency with AUTOSAR Classic environments and configuration tools.


• Deep understanding of Aurix microcontroller architecture, embedded development tools (e.g. Lauterbach, PLS), and memory mapping.


• Familiarity with ISO 26262, fault injection handling, and software safety lifecycle practices.

Preferred Skills

• Experience with Simulink, TargetLink, or similar model-based control design workflows.


• Knowledge of motor types: PM synchronous, IM, or SRM used in traction applications.


• Exposure to HIL systems (e.g. dSPACE, NI) and closed-loop validation workflows.


• Understanding of vehicle communication protocols: CAN, LIN, FlexRay, UDS.


• Awareness of inverter diagnostics, fault codes, and calibration toolchains (INCA, CANape).
