About The Position

Stellar Solutions is seeking a Space Vehicle Systems Engineer to support the U.S. Space Force’s GPS III Follow-On (GPS IIIF) program. GPS IIIF is the next generation of the Global Positioning System, with enhanced protection against signal interference, improved precision, and search-and-rescue capabilities. The role contributes to engineering, integration, testing, and delivery of spacecraft supporting national defense and global navigation.

The engineer will support the Government team in overseeing GPS IIIF spacecraft and subsystem technical development, integration, verification, and testing. Working with Government stakeholders and contractor engineering teams, the role assesses system performance and technical progress, identifies integration risks, and supports acquisition and engineering milestones. The successful candidate will communicate complex engineering information as actionable assessments that help inform program execution and mission readiness.

The position is located in El Segundo, California; a hybrid or remote work style may be considered. An active Secret security clearance is required, and a Top Secret clearance is desired. The typical annual salary range is $115,000–$145,000. The position is eligible for an annual performance bonus, an employer-funded Profit-Sharing Plan contribution, employer-paid medical benefits, PTO pay-out options, and additional company-sponsored benefits. The company states that these benefits represent an additional 30–40% of base compensation toward total compensation.

Deliverables may include engineering assessments, technical reports, test evaluations, program reviews, risk analyses, briefings, and other Government-directed products. The engineer will help assess spacecraft technical integrity, integration readiness, and performance as the vehicles progress toward delivery and operational capability.

Requirements

• Bachelor’s degree in Engineering, Mathematics, Physics, or Computer Science.

• Experience with space system and DoD program reviews, including SRR, SDR, SFR, PDR, CDR, MRR, TRR, FCA, or PCA.
• Experience using collaboration tools such as Confluence or Jira.
• Experience analyzing subsystem and program-level integrated master schedules (IMS) and contractor earned value management (EVM) data.
• Experience with spacecraft-level testing, including system performance testing, TVAC, acoustic, or EMI/EMC testing.
• Ability to communicate complex technical information effectively and establish collaborative working relationships with Government customers and contractor teammates.
• Strong work ethic, motivation, and commitment to supporting the DoD mission.
• Active Secret security clearance.

Nice To Haves

• At least 7 years of experience in space vehicle systems engineering, planning, integration, and testing.
• Experience performing multiple systems engineering and program management functions across the spacecraft development lifecycle.
• Experience conducting or supporting requirements verification activities.
• Knowledge of the DoD acquisition lifecycle, major acquisition milestones, and applicable systems engineering, testing, and production policies, standards, and practices.
• Knowledge of GPS space, ground, or user segments and their roles within the broader GPS enterprise.
• Excellent interpersonal skills and ability to work effectively across multidisciplinary technical and program organizations.
• Master’s degree in Engineering, Mathematics, Physics, or Computer Science.
• Project Management Professional (PMP), Expert Systems Engineering Professional (ESEP), Certified Systems Engineering Professional (CSEP), or Object Management Group Certified Systems Modeling Professional (OCSMP) certification.
• Top Secret security clearance.

Responsibilities

• Support systems engineering activities across the spacecraft development, integration, verification, and test lifecycle.
• Evaluate the design, development, and integration of spacecraft subsystems, including structures, mechanisms, electrical power, attitude control, thermal, propulsion, communications, and command systems.
• Assess spacecraft technical performance, subsystem interfaces, and system-level integration to identify risks, issues, and impacts to program objectives.
• Support major space system and DoD program reviews, including SRR, SDR, SFR, PDR, CDR, MRR, TRR, FCA, and PCA, as applicable.
• Review engineering documentation, technical analyses, and contractor-provided data to support Government decisions.
• Evaluate spacecraft integration and test planning, including system performance, thermal vacuum (TVAC), acoustic, and electromagnetic interference and compatibility (EMI/EMC) testing.
• Analyze subsystem and program-level integrated master schedules (IMS) and earned value management (EVM) data to assess technical progress, schedule performance, and emerging program risks.
• Support requirements analysis, verification activities, and assessment of system compliance with technical and mission objectives.
• Collaborate with Government customers, contractor engineering teams, and multidisciplinary stakeholders to resolve technical issues and align engineering activities.
• Use Confluence and Jira to support technical coordination, issue tracking, and program execution.
• Develop and communicate engineering assessments, technical findings, and recommendations to support Government confidence in spacecraft development and mission readiness.
• Contribute to engineering assessments, technical reports, test evaluations, program reviews, risk analyses, briefings, and other Government-directed products.

Benefits

• Annual performance bonus.
• Employer-funded Profit-Sharing Plan (PSP) contribution based on base compensation.
• Comprehensive employer-paid medical benefits.
• PTO pay-out options.
