Since its inception in 2004, Geost has been committed to solving mission-critical space domain and ISR challenges for DOD, IC, and commercial customers. Our vision is to revolutionize the space-based payload market with innovative and novel designs for space, terrestrial, and airborne environments. As we grow our operations in Tucson, AZ and Chantilly, VA, we remain dedicated to the collaborative and innovative culture that is the foundation of our business. Geost is an operating unit of LightRidge Solutions.

Geost seeks an enthusiastic and highly capable Senior Software Systems Engineer to work with a multi-disciplinary team to design, develop, and test space-based electro-optical sensors. A qualified candidate will be able to apply engineering best practices to ensure the success of complex missions in pioneering space projects. This position requires a U.S. Government Top Secret security clearance and is expected to spend at least 20% of the time in a classified work environment.

Duties and Responsibilities

  • Design, integrate, and develop space-based optical instruments, subsystems, and payloads for airborne and space platforms.
  • Define, allocate, and manage technical requirements for space systems using MBSE models. Ensure traceability of requirements throughout the development process and address potential conflicts or issues.
  • Lead requirements definition, allocation, and traceability across the development lifecycle.
  • Prepare and maintain technical documentation, including system design descriptions, ICDs, CONOPs, and test plans. Generate technical reports and presentations to communicate findings, progress, and recommendations to internal stakeholders and external partners. Provide technical management of project requirements, system architecture, system interfaces, mission assurance guidelines, and system compliance.
  • Support the development and testing of space payloads to be integrated on spacecraft platforms. Collaborate closely with interdisciplinary teams to ensure seamless integration and functionality of exquisite payloads.
  • Support hardware and software development teams with system-level test planning, debugging, integration, and execution of verification test procedures; analyze data and recommend design refinements.
  • Lead hardware and software V&V activities to confirm alignment with program and customer requirements.
  • Provide technical oversight of system architecture, interfaces, mission assurance, and compliance.
  • Participate in technical interchange meetings and represent the organization in project discussions.
  • Support the development, testing, and delivery of space payloads; assess and mitigate technical risks.
  • Mentor other engineers on technical topics and V&V methodologies.
  • Ability to support on-site work, as needed.
  • Ability to support travel or off-site work, as needed.
  • Perform other duties as assigned.
