Senior Satellite Bus Engineer
About The Position
Modern Technology Solutions, Inc. (MTSI) is seeking a Senior Satellite Bus Engineer to support the Mobile User Objective System (MUOS) program within Space Systems Command located in El Segundo, CA. In this role, you will help guide the design, development, integration, and testing of the satellite bus and subsystems, ensuring system‑level performance for the new mission‑critical narrowband Satellites. The ideal candidate has strong spacecraft bus engineering expertise and experience supporting Department of War (DoW) space programs. This is a highly technical, hands-on engineering role requiring deep, subsystem-level spacecraft hardware expertise rather than program or project management experience.
Requirements
- Minimum 10 years of direct spacecraft hardware engineering experience (e.g. Power, RF, Propulsion, and/or Structures) in satellite bus design, manufacturing, and assembly.
- Demonstrated technical experience in payload and bus system design, integration, and testing.
- Familiarity with MIL‑STD and DoD space and ground system requirements.
- Strong analytical, communication, and technical documentation skills.
- Experience in technical risk management.
- Must live within local commuting distance of El Segundo, CA to conduct business at the spacecraft vendor's manufacturing facilities.
- Periodic travel to San Diego will be required.
- Candidate must have an active Secret clearance to start.
- U.S. Citizenship is required for this position.
Nice To Haves
- TS/SCI clearance.
- Master’s degree in an engineering discipline.
- Experience supporting MUOS or other narrowband SATCOM space systems.
- Experience in spacecraft modeling/analysis tools such as MATLAB, STK, MSC NASTRAN or other thermal and structural analytical software tools.
- Knowledge of SSC/DoD acquisition processes and documentation practices.
- Experience supporting DoW space programs.
- Experience with Space Systems Command.
Responsibilities
- Serve as the primary, on-site technical plant representative at the vendor manufacturing facility for 2–3 days per week, providing direct, hands-on engineering oversight of satellite design, assembly, integration, and testing activities.
- Provide senior-level spacecraft bus engineering support for new MUOS spacecraft.
- Lead or contribute to the design, analysis, integration, and testing of satellite bus and subsystems, including power, thermal, structure, attitude control, guidance and navigation, propulsion, and command/data handling systems.
- Support system engineering activities such as requirements development, allocation, verification, and validation.
- Coordinate with payload, mission management, and SSC engineering teams to ensure seamless bus-payload test and integration activities, including spacecraft risk identification and mitigation.
- Conduct trade studies, assessments, and risk evaluations to support critical technical decisions related to space systems.
- Prepare, review, and update technical documentation including specifications, ICDs, technical reports, and test plans.
- Participate in key program reviews (e.g. SRRs, PDRs, CDRs, TRRs, LRRs) and support on‑orbit readiness review tasks.
- Interface with the spacecraft vendor and ground segment vendor to verify design alignment with program requirements, track compliance throughout development, and resolve technical discrepancies that could impact system performance.
- Mentor junior engineers and contribute to a collaborative engineering environment.
Benefits
- full range of medical, financial, and other benefits, dependent on the position offered.
