We are seeking a Technical Lead with extensive expertise in rugged power electronics and DC UPS systems for defense, rail, aerospace, industrial, and telecom applications.

A key requirement is hands-on design and delivery experience of at least one MIL-grade power supply, including EMI filter design, magnetic & thermal design, loop stability (Bode plots), MTBF/DFMEA reliability studies, and full compliance with MIL-STD-461, MIL-STD-1275, and MIL-STD-810.

This role combines deep technical design with cross-functional leadership, customer interaction, and support for certification and compliance processes.

Key Responsibilities

Product Development & Architecture

- Work closely with Marketing teams to capture and drive technical requirements for UPS and inverter products.

- Develop power electronics products including power and analog circuitry, magnetics, and control blocks from concept through to manufacture.

- Use a modular design approach to maximize reusability, efficiency, and scalability.

- Develop overall system architecture and ensure alignment with project requirements.

- Align resources and ensure smooth implementation of design plans.

Power Electronics & Component Selection

- Design high-reliability Mil Grade AC-DC and DC-DC Power supply ,Rectifiers and High Wattge AC DC UPS systems .

- Select and qualify power semiconductors (IGBTs, MOSFETs, GaN, SiC) and MIL-spec/AEC-Q200 passive components.

- Balance trade-offs between efficiency, thermal performance, EMI, and ruggedness.

- Perform MTBF/DFMEA, derating, and worst-case stress analysis.

EMI/EMC & Standards Compliance

- Design input/output EMI filters (common-mode, differential-mode, Pi/T/LC).

- Ensure compliance with MIL-STD-461, MIL-STD-1275, MIL-STD-810, CISPR, and IEC standards.

- Participate in standards bodies to track/drive evolving requirements.

- Work with certification agencies (BIS, UL, MIL, IEC) to achieve product approvals.

Magnetics, Thermal & PCB Design

- Design custom transformers, inductors, and chokes using FEMM, ANSYS Maxwell, or Magnetics Designer.

- optimize for thermal stability, EMI reduction, and compact rugged construction.

- Perform/Analyze thermal simulations (Icepak, Flotherm, SolidWorks Flow) to validate cooling strategies.

- Lead multi-layer PCB design for high-current rugged UPS systems, ensuring signal/power integrity and EMI robustness.

Testing, Verification & Reliability

- Lead prototype design, testing, and validation of rugged UPS products.

- Define, document, and execute developmental and compliance tests with formal verification teams.

- Conduct Bode plot stability testing (FRA/Omicron Bode 100).

- Perform failure analysis on faulty products, identify root causes, and drive corrective actions.

- Use oscilloscopes, power analyzers, LISNs, and spectrum analyzers for testing and debugging.

Technical Leadership & Collaboration

- Participate in design reviews and provide technical direction on best practices.

- Interface with customers to understand future needs and emerging technologies.

- Provide technical guidance and mentorship to junior engineers and technicians.

- Collaborate with cross-functional teams to mitigate reliability issues.

- Prepare and present detailed design reports, improvements, and recommendations.

Required Qualifications

- B.E./B.Tech in Electrical/Electronics/Power Electronics

- 15+ years in rugged power electronics, UPS, and MIL-grade power supply design

Preferred Qualifications

- Experience in defense, aerospace, rail, or telecom rugged systems.

- Hands-on expertise in MIL-STD-compliant power supply design (461/1275/810)
