At CesiumAstro, we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.
As the Principal Satellite Electrical Power Subsystem (EPS) Lead, you will be responsible for leading the design, development, and integration of the Electrical Power Subsystem for our satellite projects. You will work closely with cross-functional teams, including systems engineering, avionics, software, and mechanical teams, to ensure that the EPS meets all technical, performance, and safety requirements. Your expertise will drive innovation in power management, energy storage, and distribution solutions for our cutting-edge satellite missions.
JOB DUTIES AND RESPONSIBILITIES
- Lead the design, development, and optimization of satellite Electrical Power Subsystems, including power generation, storage, distribution, and regulation.
- Define EPS requirements, power architecture and interfaces to ensure compliance with overall satellite mission objectives and constraints.
- Perform power budget analysis, satellite energy balance analysis, EPS components trade studies, stability analysis, power system modeling and simulation, and size, weight, power, cost (SWaPC) optimization of key elements of satellite EPS.
- Collaborate with systems engineering and other subsystems leads to ensure seamless integration of EPS components within the satellite platform.
- Lead and participate in design reviews, including Preliminary Design Reviews (PDR), Critical Design Reviews (CDR), and Test Readiness Reviews (TRR).
- Oversee the selection, procurement, and testing of EPS components such as solar arrays, batteries, battery management system (BMS), power conditioning units, and power distribution hardware.
- Develop and maintain EPS documentation, including requirements and specifications documents, interface control documents, and verification and integration test plans.
- Support system-level integration and test activities, including hardware-in-the-loop testing (HIL), environmental testing, and launch preparation.
- Provide technical leadership and mentorship to a team of EPS engineers, fostering a culture of innovation, collaboration, and continuous improvement.
- Stay updated on the latest advancements in satellite power technologies and contribute to the continuous improvement of EPS design methodologies and processes.
JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
- Bachelor’s or Master’s degree in Electrical Engineering or a related field. A Ph.D. is a plus.
- Minimum of 9 years of experience in satellite Electrical Power Subsystem design and development, with a proven track record of leading successful projects.
- Strong knowledge of satellite electrical power systems, including solar arrays, batteries and battery management systems, power distribution, electric propulsion systems, isolation and grounding, electromagnetic compatibility (EMC), fault tolerance, and thermal management.
- Experience developing satellite power system architecture and defining and managing EPS requirements.
- Strong knowledge and experience with power electronics design, including isolated DC-DC power converters, inverters and motor drives, power management and control (PMC) used in satellite EPS applications (e.g. maximum power point tracking, solar array steering, electric propulsion systems, power conditioning).
- Proficiency in power system analysis tools and simulation software (e.g., SPICE, SIMetrix/SIMPLIS, MathCAD, MATLAB and Simulink, ANSYS STK).
- Demonstrated ability to lead cross-functional teams and manage complex technical projects from concept to delivery.
- Excellent problem-solving skills, attention to detail, and the ability to work in a fast-paced, dynamic environment.
- Strong communication skills, with the ability to effectively convey technical concepts to both technical and non-technical stakeholders.
- Familiarity with industry standards and requirements related to satellite power systems (e.g., ECSS, NASA standards).
- Ability to obtain and maintain a security clearance, if required.
