Job description

Overview

Embedded Software Design Engineer – Embedded Firmware for Power Electronics. You will be responsible for the end‑to‑end design, architecture, development, and validation of embedded control platforms for next‑generation power electronic systems—including DC/DC converters, inverters, motor drives, battery management systems, and EV charging solutions. By bridging hardware development and real‑time embedded firmware implementation, you will drive end‑to‑end integration, ensuring robust signal integrity, functional safety compliance, and delivery of production‑ready solutions for Power Electronics across various domains. This role requires hands‑on ownership, cross‑functional collaboration, and a commitment to high‑performance, scalable embedded design.

Key Responsibilities

• Develop real‑time firmware in C/C++ for microcontrollers, DSPs, and FPGAs, implementing control algorithms such as PID/state machines, voltage/current regulation, and PWM strategies (soft start/stop, dead‑time control), diagnostics, and communication protocols (CAN, SPI, I²C, UART).
• Develop low‑level drivers for controllers.
• Simulate and verify control strategies using MATLAB/Simulink and PLECS; support model‑based design and HIL testing.
• Ensure compliance with IEC, UL, and other relevant safety & regulatory standards, supporting diagnostics, fault handling, and system protection.
• Conduct hardware bring‑up, interface testing, and system‑level debugging using oscilloscopes, logic analyzers, JTAG, and power analyzers.
• Collaborate with cross‑functional teams (power electronics, mechanical, systems, validation) to define control architectures, timing constraints, safety‑critical behaviours, and ensure seamless hardware‑software integration.
• Generate and maintain comprehensive design documentation, including firmware architecture, test protocols, safety plans, and firmware verification reports.
• Support DFM, DFMEA, and HIL testing activities, contributing to design refinement and product maturity from prototype to production.
• Apply knowledge of embedded hardware platforms for power electronics systems, including control boards, analog/digital and mixed‑signal interface design, sensor integration, and protection strategy implementation for DC/DC, AC/DC, and inverter topologies.

Required Qualifications

• B.TECH/M.Tech in Embedded Systems, Power Electronics, or a related discipline.
• 3–6 years of experience in embedded hardware and firmware development for power electronic systems in industrial and automotive sectors.
• Proficiency in embedded C/C++, real‑time control development, real‑time system programming, peripheral configuration, and mixed‑signal hardware design.
