Job Description

We're looking for multiple Spacecraft Systems Engineers to work on projects and initiatives with a focus on U.S. national security. You will be a member of a multi-disciplinary team performing concept development, requirements generation, modeling & simulation, and analyses of advanced space payloads and spacecraft models for the Z Program’s Space Science and Security Program (SSSP). You will collaborate with scientific and engineering personnel as well as senior management to design and deliver spacecraft models to support national security missions in Livermore, CA. These positions are in the National Security Engineering Division (NSED) within the Engineering Directorate.

These positions will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level.

You will

  • Work in a diverse team of scientists and engineers to develop requirements for models of advanced spacecraft systems.
  • Apply cutting edge research to the analysis of spacecraft performance and capabilities.
  • Interface directly with management and external sponsors to communicate technical milestones and solicit input from technical leaders in the space program.
  • Communicate results through formal technical reports and presentations.
  • Review intelligence reports and derive technical assessments for the intelligence community and external sponsors.
  • Perform other duties as assigned.

Additional job responsibilities, at the SES.3 level

  • Lead a multi-disciplinary team including engineers, scientists, and technical staff to achieve specific technical goals relevant to national security missions in space systems.
  • Perform advanced analyses of spacecraft system performance and capabilities.
  • Review complex intelligence reports and derive advanced technical assessments for the intelligence community and external sponsors.
  • Mentor junior technical staff to promote professional development. Provide performance feedback to the appropriate managers as input to personnel performance evaluations.


  • Ability to secure and maintain a U.S. DOE Q-level security clearance with Sensitive Compartmented Information (SCI) access, which requires U.S. citizenship.
  • Bachelor’s degree in Engineering, Physics, Computer Science or related field or the equivalent combination of education and related experience.
  • Broad aerospace and/or spacecraft engineering experience with designing, assembling, testing, or operating flight hardware and/or software.
  • Experience working as a member of a multidisciplinary project team that may include engineers, scientists, designers, and technicians.
  • Demonstrated ability to devise solutions for moderately complex to complex problems that require in-depth analysis of tangible and intangible factors.
  • Proficient verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information to colleagues, management, or sponsors.
  • Ability to travel as necessary to present analyses to sponsors, stakeholders and counterparts.

Additional qualifications at the SES.3 level

  • Advanced knowledge of concepts related to aerospace and/or spacecraft engineering and demonstrated experience leading the development of proposals or systems to meet space mission customer requirements.
  • Significant practical experience and/or theoretical depth in one or more spacecraft subsystems or functions such as: system requirements, integration & test, launch support, on-orbit operations, attitude and orbital controls, propulsion, solar array design, electrical power systems, avionics, data handling and on-board processing, thermal, structures and mechanisms, telemetry, tracking, and control (TT&C), RF antennas and communications, synthetic aperture radar (SAR) payloads, and/or electro-optical (EO) payloads.
  • Experience estimating cost and schedule of scientific, technical, spacecraft, or aerospace projects.
  • Significant experience and demonstrated track record of success developing and implementing creative solutions to a diverse range of complex multi-disciplinary problems.
  • Ability to effectively manage multiple parallel tasks, often requiring the resolution of conflicting work requirements and prioritization of tasks toward predetermined long-range targets.

Qualifications We Desire

  • Current active DOE Q-level security clearance with SCI access.
  • Master's degree in Engineering, Physics, Computer Science, or related field.
  • Practical knowledge of industrial spacecraft engineering processes, standards, and practices.
  • Familiarity with orbital mechanics, orbit determination, satellite maneuvering, identification or tracking.
  • Experience with spacecraft operations in any phase, including but not limited to launch, deployment/initialization, mission operations, and disposal.
  • Experience with on-orbit anomaly resolution, spacecraft failure review boards, and/or fault tree analysis.
  • Experience with software tools, methods, and techniques as applied to spaceflight systems, such as: ANSYS, Thermal Desktop, MATLAB STK, SolidWorks, PDM, COMSOL, or Cameo.
  • Experience conducting research and analysis related to national security issues, including extensive experience with Intelligence Community and Department of Defense needs and practices, including SCI security marking, intelligence oversight and compliance, and related security and safety practices.
  • Familiarity with machine learning and/or data science theories or techniques.
