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 Battery Testing and Development Engineer to support the development and qualification of lithium-ion battery systems for space applications. The role involves hands-on testing, validation, and integration of battery packs and Battery Management Systems (BMS) for space and Low Earth Orbit (LEO) missions. The ideal candidate will bring a strong understanding of aerospace-grade battery characterization, environmental testing, and technical documentation aligned with industry standards.

Key Responsibilities:

• Conduct functional, performance, and environmental testing on lithium-ion battery packs designed for spacecraft and aerospace missions.
• Validate battery behavior across thermal and orbital environments, including extreme charge/discharge profiles.
• Interface with space-grade BMS for configuration, diagnostics, and fault management.
• Operate automated test setups involving programmable power supplies, electronic loads, DMMs, thermal chambers, and SCPI-controlled systems.
• Log and analyze telemetry data for voltage, current, and temperature; compute SoC, capacity, and degradation profiles.
• Document test procedures, results, and corrective actions in line with ECSS, MIL-STD, UN 38.3, and ISRO requirements.
• Support battery design optimization including pack configuration, redundancy planning, and harness routing.
• Collaborate with system, QA/QC, and engineering teams to meet qualification targets and mission requirements.

Qualifications and Skills:

Education and Experience:

• Bachelor’s degree in Electrical Engineering, Power Systems, or a related field.
• 2–3 years of hands-on experience with lithium-ion battery packs and BMS in aerospace or defense-grade systems.

Technical Skills:

• Proficient in testing battery charging profiles (CC/CV, float, trickle) and C-rate-based discharge analysis.
• Familiar with lab instrumentation including Keysight/Rigol PSUs, Fluke DMMs, and thermal vacuum chambers.
• Understanding of test automation, scripting (preferably Python), and SCPI protocol.
• Experience with aerospace or defense standards such as ECSS-E-ST-20-07, MIL-PRF-32383, or ISRO guidelines.

Preferred Skills:

• Knowledge of thermal vacuum testing, radiation impact on batteries, and orbit cycling validation.
• Familiarity with low-outgassing materials, space-qual PCB design, and spacecraft power integration.
• Exposure to space agency workflows (e.g., ISRO, ESA, NASA) or defense mission cycles.

Soft Skills:

• Excellent documentation and analytical reporting abilities.
• Detail-oriented with a strong commitment to safety and compliance.
• Capable of working independently in a fast-paced, highly regulated engineering environment.
