Power Design Engineer

As a Power Design Engineer, you will be responsible for designing, developing, and validating power electronics systems (AC-DC, DC-DC converters, power supplies, etc.) tailored for rugged, high-reliability aerospace and defence applications. You will work closely with system engineers, PCB designers, test engineers, and hardware teams to deliver power subsystems that meet strict performance, safety, and environmental requirements. Key Responsibilities: Design and develop power conversion circuits (ACDC, DCDC) for defence-grade electronic products. Perform circuit simulation, analysis (efficiency, thermal, EMI/EMC), and optimization using tools like SPICE, MATLAB/Simulink, or similar. Select and size components (magnetics, capacitors, switching devices) for power systems under performance and cost constraints. Develop PCB layouts for power electronics, ensuring thermal management, signal integrity, and compliance with high-reliability design standards. Define protection schemes, such as over-current, over-voltage, short-circuit protection, and implement in hardware. Work with test engineers to develop test plans, validate prototypes, and iterate designs based on test feedback (efficiency, load regulation, thermal performance). Perform reliability analysis, MTBF estimation, and design for lifetime in harsh environments (vibration, temperature, humidity). Collaborate on system integration: interface power modules with other subsystems, ensuring proper power sequencing, startup/shutdown behavior, and safety. Support documentation: create design reports, test plans, test reports, user manuals, and maintenance guidelines. Stay current on power electronics technology trends, new components, and best practices.

Antigone Solutions is a defence-focused start-up that specializes in the design, development, engineering, and manufacturing of electronics solutions for aerospace and defence applications. We provide end-to-end engineering capabilities from custom module and subsystem design, to prototype development, to build-to-specification and build-to-print manufacturing. Our mission aligns with Make in India initiatives, collaborating with defence labs and aerospace organizations to build indigenous, high-reliability systems.
