About Azista Space Systems:

Azista Space Systems is a leading player in the Indian space market and is rapidly establishing itself as a global force in the space industry. We specialize in providing vertically integrated solutions to our clients, covering a wide range of services and products, including satellites, satellite buses, payloads, sub-systems, and satellite communication equipment.

What We Do:

At Azista Space Systems, we offer comprehensive design, development, manufacturing, testing, and qualification services for spaceborne equipment. Our innovative and integrated approach ensures that we deliver top-quality solutions tailored to meet the unique needs of our customers.

Role Summary:

We are seeking a skilled and detail-oriented Power Electronics Engineer with 2–3 years of experience in the design, testing, and validation of DC-DC converter systems. The ideal candidate will have hands-on expertise in SMPS topologies, inrush and transient protection, e-fuse integration, and thermal reliability, with a strong foundation in technical documentation for engineering reviews.

Key Responsibilities:

Design and Development:

• Design and develop various DC-DC converter topologies (buck, boost, flyback, push-pull, forward) for embedded and industrial systems.
• Implement and validate protection strategies including inrush current limiting, transient voltage suppression, and electronic fuses.
• Select appropriate power components considering electrical, thermal, and derating criteria to ensure system reliability.
• Perform thermal simulations and stress analyses to evaluate worst-case conditions.

Validation and Testing:

• Support schematic development and collaborate with layout teams for EMI/thermal compliance and safety standards.
• Validate and debug power converter prototypes using oscilloscopes, isolation probes, electronic loads, and power analyzers.
• Work closely with cross-functional teams to ensure successful integration into larger systems.

Documentation:

• Prepare detailed design documentation including block diagrams, trade studies, derating analysis, and component justification.
• Develop and maintain Interface Control Documents (ICD) for subsystem alignment.
• Generate reports and technical presentations for Preliminary and Critical Design Reviews (PDR/CDR).
• Document simulation outcomes, lab results, and validation test summaries in compliance with engineering and quality standards.

Qualifications and Skills:

Education and Experience:

• Bachelor’s degree (B.E./B.Tech.) in Electrical, Electronics, or Power Electronics Engineering.
• 2–3 years of experience in power electronics development with a focus on DC-DC converters.

Technical Skills:

• Strong understanding of SMPS operation and DC-DC converter design.
• Practical experience with inrush control, transient protection, and e-fuse circuitry.
• Proficiency in simulation tools such as LTspice, PSpice, Simulink, or PLECS.
• Skilled in using lab instruments for power testing and measurement.
• Familiar with thermal modeling and component stress/derating methodologies.
• Experience producing engineering documentation aligned with aerospace/industrial standards.

Preferred Qualifications:

• Exposure to aerospace, automotive, or defense power systems.
• Familiarity with standards such as MIL-STD, DO-160, or IEC.
• Knowledge of digital power control and embedded firmware integration is a plus.

Soft Skills:

• Excellent communication and documentation skills.
• Strong analytical thinking and problem-solving abilities.
• Proactive and collaborative, able to work independently or within a cross-disciplinary team.
