Kepler is on an audacious mission to deliver Internet connectivity to space, creating the infrastructure to support the rapidly increasing data needs of the space economy. With 23 satellites launched to date and our optical constellation on the horizon, our ambition is to improve access to space-generated data, whether in LEO, MEO, GEO, or beyond! Kepler is hard at work innovating and continuing to grow and expand our most important asset – the Team!
We are on the hunt for a talented Electrical Engineer with a specialization in electrical power systems, a passion for emerging technology, likes to take on challenges, and would love to join Kepler’s Electrical team. Here is a little more detail on what you can expect to work on:
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:
- Experience with Space Power Systems, ESAECSS and/or NASA standards.
- Experience with solar panel systems.
- Python scripting experience.
- Usage of AI-tools.
