Electrical Power Systems & Battery Engineer
Kepler Communications
Key Responsibilities:
- Design, develop, and support the electrical power systems for Kepler’s current and next generation of satellites including:
- Battery pack architecture and BMS including battery cell evaluation and power modeling
- Solar-array battery charging regulator systems
- Power-tree design support for electrical sub-systems owners
- Own new designs from start to finish or iterate on existing designs based on new feature requests, lessons learnt, and DFx (DFA/DFM/DFT)
- Work closely with other cross-functional engineering teams including systems, RF, mechanical, software, and FPGA to develop full product solutions
- Follow relevant internal and external “electrical design-for-space” standards to ensure the long term reliability of PCBAs in critical low-earth orbit missions
- Participate in and drive design reviews
- Create and own the execution of design validation test plans for new power components and systems
- Perform functional and performance testing on individual boards or integrated sub-systems as part of bring up and design validation/verification including accelerated lifetime testing where needed
Required Skills & Qualifications:
- 5+ years of post-undergrad electrical hardware design experience with a strong focus on battery system design and electrical power systems
- Bachelor's degree in electrical engineering or equivalent
- Experience in Lithium-ion battery pack construction sizing, balancing, protection, coulomb counting, and thermal management
- Strong understanding of power technologies including discrete and integrated switch mode power supplies
- Extensive experience in designing and executing qualification test plans for battery and power systems
- Strong communication skills and the ability to put together thorough design documentation
- Circuit and layout simulation experience (SPICE or comparable)
- Experience with or an understanding of the LEO environment for power electronics (e.g. radiation effects)
- Experience with one or more CAD tools (Altium, Allegro, KiCad, etc.)
- Understanding of PCB design principles for signal and power integrity as well as thermal management under vacuum.
- Highly proficient in a lab environment and experience using standard tools such as oscilloscopes, spectrum analyzers, multimeters, VNA’s, etc.
Bonus Points:
