Role Lead the definition, documentation, and maintenance of the complete GEO spacecraft system architecture, including high‑power payload accommodations, propulsion systems for orbit raising and station‑keeping, and high‑throughput communication links. Identify and rapidly solve cross‑functional issues that arise at every stage of the satellite lifecycle. Define and manage spacecraft internal and external interfaces (mechanical, electrical, thermal, data) to ensure seamless integration and compatibility across subsystems, especially between Bus and Payload systems. Act as the technical owner and primary point of contact for critical system budgets, particularly Mass and Power Budgets. Establish and maintain technical budget tracking tools and reports, providing accurate, up‑to‑date status and forecasts to project leadership and stakeholders. Provide technical guidance and oversight to subsystem engineers, ensuring their designs are integrated correctly and meet system‑level design criteria and budgets. Support Assembly, Integration, & Test (AI&T) activities and mission operations by leading the systems‑level analysis and resolution of technical anomalies. Requirements Bachelor’s or Master’s degree in Engineering (Aerospace, Electrical, Mechanical, etc.) or a related technical discipline. 3 to 10 years of experience in integrated system design, integration, and/or test. Experience as a hands‑on engineer or other technical domain expert. Note that both junior and senior engineers are sought for this role. Track record of solving hard problems independently. Ability to lead outside of the traditional reporting chain. Proven experience in managing complex technical budgets (e.g., mass, power) and enforcing design discipline. Proven ability to work in a fast‑paced environment, overcome obstacles with creative solutions, and clearly document/communicate tactical plans. Bonus Experience working through a complete GEO spacecraft development lifecycle. Familiarity with Smartsheet, Jira, and Confluence. Deep technical experience across multiple domains.
