Job summary

CesiumAstro, Inc. in Colorado is seeking a senior Electrical Systems Engineer to lead satellite integration, EGSE development, and test/verification activities in a lab environment.

You will collaborate with Systems Engineering and Program Management to plan AI&T schedules, validate interfaces, and oversee acceptance testing like vibration, EMI/EMC, and thermal vacuum to ensure mission readiness.

Qualifications

• B.S. degree in aerospace, electrical, or related engineering discipline.
• Minimum of 8 years experience including prior significant roles on spacecraft or related systems assembly, integration and test operations.
• Must have prior experience in multiple stages of satellite and component/GSE development including early design for test, test operations, and operational missions.
• Experience in requirements management, system design, integration, and test.
• Proficiency in at least one scripting language such as Python, with willingness to learn new ones.

Responsibilities

• Define requirements, designs, and provide ongoing support for electrical ground support equipment (EGSE) development for testing a satellite.
• Work with Systems Engineering to establish test plans and maintain requirements verification test matrix.
• Work with Program Management to build AI&T schedules that inform master schedules.
• Support on-orbit mission operations with knowledge gained from integration/test activities.
• Validate all electrical interfaces between test equipment and flight hardware.
• Provide expert guidance and peer review for satellite assembly, integration, and test campaigns.
• Develop and execute acceptance/qualification testing activities including, but not limited to, vibration, acoustic, shock, propulsion static fires, EMI/EMC, RF, self compatibility, ground compatibility, day in the life (DITL), and thermal vacuum testing.
• Lead anomaly reporting as well as root cause and corrective action implementation in a manner that indicates sound engineering judgement and applies excellent communication skills.
• Troubleshoot electrical issues during sub-system, and component integration and test.
• Lead and participate in integration and test readiness reviews along with post-operational briefings.
• Analyze, document, and present integration and test data to support verification activities.
• Author test procedures and lead/conduct test activities.
• Support satellite AI&T and launch operations effort (including the sequence of activities, required facilities, special test equipment, personnel, schedule, risks, and opportunities).
• Work both independently and in teams to achieve integration and test objectives.
• Identify, support, and help enforce safety policies and practices for assembly, integration, and test activities.
• Work onsite in the lab and cleanroom daily for AI&T operations.
