SENIOR BATTERY CHEMISTRY ENGINEER – SPACECRAFT & SATELLITE POWER SYSTEMS
Job Location: Bengaluru
About Us:
Join a team that is redefining the accessibility of space. Azista space is a transformative force in the global aerospace sector, uniquely positioned at the intersection of indigenous innovation and industrial scalability. Operating India’s first private-sector satellite mass-production facility in Ahmedabad, we have bridged the gap between complex engineering and high-volume manufacturing.
As a vertically integrated leader, we provide end-to-end solutions from the precision design of satellite buses and advanced payloads to mission management and communication systems. We don’t just build hardware, we are democratizing the final frontier by providing global clientele with the cost-effective, high-performance technology needed to power the next generation of orbital missions. At Azista, you won't just be starting a job, you’ll be fuelling the future of space exploration.
About the Role:
Are you passionate about advancing the future of space technology through cutting-edge battery innovation? We are looking for an experienced Staff Engineer – Lithium-Ion Battery Chemistry to lead the development and qualification of high-reliability lithium-ion battery systems for spacecraft and satellite applications.
In this role, you will drive the chemistry and electrochemical evaluation of lithium-ion cells, lead life-cycle testing, degradation analysis, and failure investigations, and collaborate with multidisciplinary engineering teams to deliver mission-critical energy storage solutions. You'll play a key role in defining qualification strategies, improving battery reliability, and ensuring compliance with international aerospace standards while mentoring engineers and influencing technical decisions throughout the product lifecycle.
This is an excellent opportunity to work on next-generation spacecraft power systems where your expertise will directly contribute to mission success.
Roles & Responsibilities:
- Lead the electrochemical evaluation, characterization, and performance assessment of Lithium-Ion cells intended for spacecraft battery applications, ensuring they meet stringent mission reliability and performance requirements.
- Develop, execute, and optimize qualification, characterization, and long-duration life-cycle testing plans under mission-specific operating conditions while establishing scientifically sound testing methodologies.
- Analyze battery degradation trends by evaluating capacity fade, impedance growth, energy retention, and remaining useful life (RUL), and develop predictive models that support mission life estimation and long-term battery performance.
- Perform comprehensive cell failure investigations using electrical, electrochemical, and physical characterization techniques to identify root causes of degradation and correlate findings with manufacturing processes, material selection, operating conditions, and environmental stresses.
- Review and interpret electrochemical test data including Capacity Retention, Coulombic Efficiency, Electrochemical Impedance Spectroscopy (EIS), DC Internal Resistance (DCIR), Hybrid Pulse Power Characterization (HPPC), Open Circuit Voltage (OCV), Rate Capability, Charge-Discharge Characteristics, and Self-Discharge to provide technical recommendations.
- Define battery cell acceptance criteria, qualification methodologies, screening processes, charging strategies, and operating limits to improve reliability, safety, and mission performance.
- Collaborate closely with battery electronics, mechanical, thermal, manufacturing, reliability, and systems engineering teams throughout product development to ensure seamless integration of battery systems into spacecraft platforms.
- Prepare technical reports, qualification documents, reliability assessments, customer presentations, and engineering recommendations while ensuring compliance with ECSS, NASA, and other applicable aerospace quality and reliability standards.
- Provide technical leadership by mentoring engineers, supporting multidisciplinary development activities, driving root cause investigations, and facilitating data-driven engineering decisions throughout the battery development lifecycle.
