This role defines and influences mission architecture, constellation strategy, and long-term orbital operations concepts to ensure mission performance, resilience, scalability, and sustainability.\nThis position operates as a technical authority within a multidisciplinary engineering environment, providing leadership in mission analysis, constellation design, orbital dynamics, and system-level trade studies. The Senior Staff Systems Engineer partners with engineering leadership, program stakeholders, and customers to shape requirements, evaluate architectural trades, and drive data-informed decisions from early concept development through deployment, operations, replenishment, and end-of-life planning.\nJOB DUTIES AND RESPONSIBILITIES\nLead development of mission analysis frameworks, simulation architectures, and advanced modeling tools for LEO constellation design and optimization.\nDefine and influence constellation architecture, including sizing, orbital placement, coverage strategy, and long-term scalability.\nLead system-level trade studies and evaluate competing mission architectures, orbital configurations, and operational concepts.\nEstablish technical baselines for constellation performance, operational constraints, and mission design assumptions.\nProvide technical direction and expert review of mission analysis products across multiple programs and engineering teams.\nDrive alignment between mission requirements, system design, and operational feasibility.\nServe as technical authority for orbital mechanics, constellation dynamics, and long-term orbital behavior modeling.\nLead analysis of perturbation effects including gravity harmonics, atmospheric drag, solar radiation pressure, and related environmental influences.\nDefine strategies for constellation maintenance, including station-keeping, orbit optimization, and collision risk mitigation.\nLead planning for constellation replenishment, replacement strategies, and end-of-life disposal to ensure long-term sustainability and regulatory compliance.\nDevelop and guide autonomous constellation control strategies and high-level operational concepts for fleet-wide management.\nProvide expert-level recommendations on constellation resilience, robustness, and operational efficiency.\nLead system-level analysis of communications performance including coverage, capacity, latency, and connectivity across constellation architectures.\nIntegrate communications constraints and performance drivers into mission and constellation design decisions.\nPartner with systems engineering and communications teams to define mission requirements, performance metrics, and operational constraints.\nEvaluate mission impacts of communications architecture tradeoffs and provide senior technical recommendations.\nEnsure alignment between system performance models and end-to-end mission objectives.\nServe as a senior technical advisor to systems engineering, spacecraft engineering, flight software, mission operations, and program leadership teams.\nLead technical reviews, architecture boards, and mission readiness assessments.\nPresent complex technical findings and architectural recommendations to executive stakeholders, customers, and technical governance bodies.\nInfluence program direction through data-driven analysis, risk assessment, and system-level technical insight.\nProvide mentorship and technical leadership to engineers across mission analysis and systems engineering disciplines.\nEnsure accuracy, traceability, and technical rigor across all mission analysis products and documentation.\nPerform additional duties and responsibilities as assigned.\nJOB REQUIREMENTS AND MINIMUM QUALIFICATIONS\nBachelor’s degree in Aerospace Engineering, Astrodynamics, Mechanical Engineering, Physics, Systems Engineering, Applied Mathematics, or a related technical field.\n8+ years of relevant experience in mission analysis, orbital mechanics, spacecraft systems, constellation design, or related aerospace disciplines.\nMaster’s degree in Aerospace Engineering, Astrodynamics, Physics, Systems Engineering, Applied Mathematics, or a related technical field with 6+ years of relevant experience may be considered.\nDeep expertise in LEO constellation design, architecture development, and lifecycle operations.\nAdvanced experience developing and leading simulation frameworks and mission analysis tool chains.\nExpert understanding of orbital perturbations including drag, gravity field variations, and solar radiation pressure.\nStrong command of satellite operations, mission planning, and autonomous constellation management strategies.\nExpert knowledge of communications system performance and its impact on mission architecture.\nAdvanced ability to translate system requirements into executable models, architectures, and operational concepts.\nStrong mathematical, analytical, and systems thinking capabilities.\nDemonstrated ability to lead technical decision-making in complex, multi-system environments.\nStrong communication skills with the ability to influence technical and non-technical stakeholders.\nDemonstrated technical expertise in mission analysis, constellation architecture, orbital mechanics, spacecraft operations, or related aerospace disciplines. \nRecognized expert in orbital mechanics, astrodynamics, and spacecraft mission analysis.\nAbility to communicate complex technical concepts clearly in written and verbal formats.\nAbility to participate in technical reviews, architecture boards, and decision-making forums.\nPrimarily office and engineering development environment.\nProficiency in orbital analysis tools (STK, GMAT, FreeFlyer, or similar).\nPython, or similar analytical and modeling tools.\nExperience with advanced data visualization and mission simulation platforms, version control systems (Git, GitLab, Bitbucket, or similar), and collaboration platforms (Confluence, SharePoint, or similar).\nExceptional written and verbal communication skills.","description_format":"text","description_chars":6183,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Embedded
