Roles & Responsibilities

• Power Electronics & EPS Architecture
• Design and develop space-grade Electrical Power Systems (EPS), including solar array conditioning interfaces, Battery Management Systems (BMS), and reliable Power Distribution Units (PDU) with fault-tolerant architecture.
• Develop high-efficiency, high-power-density DC-DC converters using various topologies such as buck, boost, LLC, and flyback, along with motor drive electronics for spacecraft applications.
• Integrate spacecraft power subsystems using standard communication protocols like CAN, SpaceWire, MIL-STD-1553B, SPI, I2C, and RS422/RS485 to ensure seamless system communication.
• Simulation, Modeling & Optimization
• Perform simulation and modeling of complex power electronic circuits using LTSpice, PSpice, and MATLAB/Simulink to improve efficiency, transient response, and control loop stability.
• Follow Design for Manufacturing (DFM), Design for Assembly (DFA), and Design for Reliability (DFR) principles while meeting strict mass, power, and thermal constraints.
• Hardware Bring-Up, Testing & Qualification
• Prepare and review circuit schematics, support multi-layer PCB layout reviews, and carry out hands-on hardware bring-up and validation in laboratory environments.
• Conduct environmental qualification testing, including Thermal Vacuum (TVAC), vibration, shock, and Environmental Stress Screening (ESS), to verify hardware reliability.
• Reliability, Compliance & Leadership
• Perform Failure Modes, Effects, and Criticality Analysis (FMECA), Worst-Case Analysis (WCA), and component stress derating in accordance with space reliability standards.
• Resolve EMI/EMC compliance challenges and select suitable radiation-hardened, space-grade components for mission-critical systems.
• Mentor junior engineers, maintain high-quality hardware documentation, and encourage the adoption of advanced power technologies, including GaN and SiC-based architectures.

Required Qualifications & Skills

• Education: Bachelor's or Master's degree (B.E./B.Tech/M.E./M.Tech) in Electrical Engineering, Power Electronics, Electronics Engineering, or a closely related discipline.
• Experience: Minimum 2 years of hands-on experience in power electronics hardware design, preferably within Aerospace, Defence Electronics, Space Systems, or other high-reliability industrial environments.
• Power Electronics Hardware: Strong practical knowledge of Switched-Mode Power Supplies (SMPS), multi-topology DC-DC converters, GaN/Si MOSFETs, gate driver circuits, and analog/digital feedback control loops.
• Design & Simulation Tools: Hands-on proficiency with LTSpice, PSpice, MATLAB/Simulink, and PCB design tools such as Altium Designer, Cadence Allegro, or KiCad.
• Reliability & Standards: Good understanding of EMI/EMC design practices, thermal management, component derating, Failure Modes, Effects, and Criticality Analysis (FMECA), and Worst-Case Analysis (WCA).
• Soft Skills: Excellent analytical and problem-solving abilities, a quality-focused engineering approach, collaborative mindset, ownership, and effective technical communication skills.

Preferred Qualifications (Optional)

• Space Standards Knowledge: Familiarity with ECSS or NASA standards related to space-grade electronics qualification, radiation-tolerant component selection, and derating methodologies.
