1. About CREATARA
At CREATARA, design thinking is more than a strategy, it is a way of life. This guiding principle empowers us to explore uncharted territories, challenge baseline assumptions, and reimagine the very fabric of automotive technology. We provide a visionary engineering space where we rethink automotive systems from the ground up, moving beyond conventional boundaries to create the future of mobility.
2. Role Overview
As the Senior Powertrain & Systems Engineer, you will hold a critical leadership position responsible for architecting, developing, and validating advanced power electronic systems. You will spearhead innovation within our electrified powertrains, focusing on high-performance 2-wheeler EVs, integrated charging architectures, and sophisticated energy management systems. This role requires a high-level engineer who can bridge the gap between ambitious vehicle performance targets and rigorous hardware execution within the extreme packaging constraints of a compact 2-wheeler frame.
3. Core Responsibilities
3.1 Powertrain Strategy & System Sizing
- Performance Translation: Translate vehicle-level performance targets including Top Speed, Acceleration (0–40 kmph), Gradeability, and Payload into definitive technical specifications for the motor and battery systems.
- System Sizing & Topology: Architect the powertrain topology for 48V/72V systems. Evaluate and select ideal motor configurations (Hub vs. Mid-drive) based on torque-speed curves, peak vs. continuous power requirements, and thermal limitations.
- Battery Configuration: Define battery capacity (Ah/kWh) and cell configuration (Series/Parallel), balancing range targets against the significant space and weight constraints inherent to a 2-wheeler chassis.
- C-Rate & Current Analysis: Conduct rigorous analysis of peak current demands during high-torque events, such as uphill climbing, to ensure battery cells and the BMS manage discharge rates without excessive voltage sag or thermal runaway.
3.2 High Voltage (HV) Harness & Distribution
- Harness Architecture: Architect EMI/EMC-shielded HV paths and wiring harnesses designed specifically for the high-vibration environment and limited routing space of a compact 2-wheeler frame.
- Connector & Component Selection: Govern the selection and integration of compact, vibration-proof, and waterproof HV connectors (e.g., Chogori, Amphenol) and switchgear, including contactors, fuses, Manual Service Disconnects (MSD), and High-Voltage Interlock Systems (HVIL).
- Thermal & Safety Management: Analyze and implement advanced cooling strategies for power semiconductors and battery interconnects to ensure operational safety and longevity.
3.3 Charging System Design & Interoperability
- Charging Architecture: Architect the strategy for On-Board Chargers (OBC) vs. Off-Board DC Fast Charging, optimized for 48V/72V battery environments.
- Standardization Compliance: Lead the implementation of India-specific standards, specifically IS 17017 and the LECCS (Light Electric Combined Charging System) Type 7 connector for unified AC/DC charging.
- Grid Resilience & Protection: Engineer robust protection circuits for over-voltage, surge, and thermal runaway. Optimize AC-DC conversion (PFC and isolated DC-DC stages) to ensure the system is resilient to dirty power grids and voltage fluctuations common across Indian geographies.
4. Qualifications & Experience
4.1 Education
- Bachelor's or Master's degree in Electrical Engineering, Power Electronics, Automotive Engineering, or a related technical field.
4.2 Professional Experience
- 2+ years of hands-on experience in power electronics within the automotive or EV domain, with a proven track record of delivering high-voltage systems from concept to validation.
4.3 Technical Proficiency
- First-Principles Engineering: Absolute proficiency in calculating wheel torque, tractive effort, and battery energy density from first principles.
- Safety & Distribution: Deep expertise in power distribution, relay logic, and high-voltage protection within EV architectures.
4.4 Software & Tools
- Simulation: Essential proficiency in MATLAB/Simulink, LTspice, or PSIM for system-level and circuit-level modeling.
- Modeling: Advanced experience with Excel-based models for rapid drive cycle simulation and energy consumption feasibility studies.
- Processes: Familiarity with ASPICE and V-model development cycles.
5. Nice-to-Have Skills
- Experience in a fast-paced EV startup or high-volume automotive OEM.
- Specialized exposure to ultra-fast charging systems and advanced energy management strategies.
- Strong technical understanding of DC-DC converters, inverters, and PDU design using SiC/GaN technologies
