Systems Integration & Test Engineer - Space Systems

Salary: $97,000 - $127,000 | Location: Longmont, CO | Active TS/SCI Clearance Required

Support the integration, verification, and operational readiness of mission-critical space systems supporting satellite ground systems and orbital platforms. This role focuses on integrating in-house developed and COTS/GOTS components across complex systems of systems, executing system-level test activities, resolving hardware and software integration issues, and coordinating with engineering and operations teams. The ideal candidate brings experience in integration and test, systems engineering practices, Linux and virtualized environments, and the ability to troubleshoot complex technical issues in a fast-paced, security-controlled environment.
A Day in the Life - What you'll do

• Plan, implement, execute, document, and maintain integration and test solutions for in-house developed and COTS/GOTS components, elements, subsystems, and systems.
  
• Translate customer requirements and contractual objectives into practical test strategies that meet technical, schedule, and cost constraints.
  
• Develop and execute comprehensive test plans, procedures, schedules, and integration approaches to verify system functionality and performance.
  
• Integrate components across complex systems of systems, identify defects and workarounds, troubleshoot interface issues, and help achieve required end-to-end system capabilities.
  
• Define and validate functional and technical specifications, hardware/software interfaces, and system input/output parameters.
  
• Coordinate subsystem and system-level testing with program teams, engineering organizations, and operational stakeholders.
  
• Apply systems engineering practices to support requirements decomposition, verification planning, traceability, and system validation using tools such as DOORS and Cameo.
  
• Document system configurations, test procedures, troubleshooting steps, and operational processes using technical notes, engineering instructions, and program documentation.
  
• Support software version testing and evaluation, providing actionable feedback to engineering and development test teams.
  
• Maintain and troubleshoot systems within customer-owned facilities while complying with applicable security, configuration management, and operational standards.
  
• Facilitate communication between operations and engineering teams regarding system status, defects, anomalies, and corrective actions.
  
• Collect and report relevant technical and test metrics to support program status briefings and management decisions.
  
• Collaborate with team members through Agile practices and tools to coordinate testing activities, track issues, and communicate progress.
  
• Provide informal training and on-the-job guidance on system design, data flow, integration approaches, and operational procedures.
  
• Support occasional 24/7 test events and after-hours operational anomaly response when required by mission needs.

Required Qualifications

• Experience in Integration and Test (I&T) and/or system- or subsystem-level verification.
  
• Experience in the space domain, including satellite ground systems and/or orbital platforms.
  
• Exposure to Linux environments, virtualization technologies, virtual machines, containers, and hardware/software interfaces.
  
• Familiarity with systems engineering practices, including requirements management and requirements decomposition.
  
• Familiarity with systems engineering tools such as IBM DOORS and/or Cameo.
  
• Experience working in Agile environments, with strong technical writing, collaboration, and interpersonal communication skills.
  
• Demonstrated ability to learn, troubleshoot, and resolve issues involving complex technical systems.
  
• Ability to work effectively in a fast-paced, dynamic environment with changing technical and operational priorities.
  
• Active and current TS/SCI clearance required to start.

Preferred Qualifications

• Experience developing or maintaining Requirement Verification Plans (RVPs), Requirements Verification Traceability Matrices (RVTM), and other integration and verification artifacts.
  
• Previous experience supporting one or more of the following programs or mission areas: OPIR, Next Generation Geosynchronous Earth Orbit (NGG), or Space Based Infrared System (SBIRS).
  
• Familiarity with Agile integration and verification tools such as Confluence, Jira, and Zephyr.
  
• Experience with software testing methodologies, test execution, defect tracking, and software test tools.
  
• Experience supporting 24/7 operational environments, including on-call or recall requirements for key personnel.
  
• Experience supporting spacecraft or satellite system anomaly investigation, troubleshooting, response, and resolution.
  
• Experience coordinating integration and verification activities across multiple subsystems, engineering teams, and operational organizations.
