Battery Testing and Development Engineer
Employment Type : Full Time
Location : Ahmedabad
Department : Power Electronics Design
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.
