Vast is looking for a Senior Battery Electrical Engineer, reporting to the Senior Director of Power & Systems, to support the development of the Battery systems for our artificial-gravity human-rated space stations. This will be a full-time, exempt position located in our Long Beach location.

Responsibilities: 

• Design and develop advanced battery systems for the first commercial space station


• Complete and document technical surveys of battery technology for next generation space stations


• Own cell selection for optimized for energy, power, and cost considering a wide array of technologies


• End-to-end ownership of battery and battery management system specification, architecture, simulation, schematic capture, PCB design, board-level bring-up and validation, environmental qualification (vibration, thermal vacuum), and integrated system-level validation


• Design of circuits to implement functions such as battery voltage/current sensing, charge balancing, disconnect relays, galvanic isolation, and fault detection


• Development of battery models for electronic simulation and system modeling and battery state-of-charge estimation algorithms


• Perform due diligence on designs including reliability calculations, FEA, FMEA, and DFMEA

Minimum Qualifications:

• Bachelor's degree in electrical engineering


• 4+ years of experience developing electrical hardware 

Preferred Skills & Experience:

• 4+ years of experience in battery electrical systems for space vehicles across the product lifetime including design, development, test, in flight operation, and anomaly resolution


• Ability to creatively solve problems and bring multiple disciplines together while assessing risk and making design and development decisions with incomplete data set


• Experience working with instrumentation and data acquisition (e.g. SPICE, SQL, and/or National Instruments hardware)


• Experience with software programming: Matlab, Python, C/C++, etc


• Experience with vehicle and instrumentation buses such as Ethernet, CAN, SPI, and I2C, as well as serial I/O (RS232/422/485)


• Experience with full-lifecycle product development


• Experience with battery design for spaceflight environment, verifying workmanship and operability through environmental tests (random vibration, shock, thermal, TVAC, and thermal runaway testing)


• Experience with Siemens NX and Altium, or equivalent electrical design platforms


• Strong sense of accountability and integrity with excellent written and verbal communication skills


• Ability to thrive at an early-stage startup where you will have the opportunity to help create and optimize key systems and processes
