About the Job

Requirements

  • A bachelor's degree and at least 6 years of relevant experience, or a graduate degree and at least 4 years of relevant experience; alternatively, at least 10 years of related experience may substitute for a degree.
  • Eligibility to obtain a Department of Defense Secret security clearance.
  • Experience with infrared or electro-optical sensing systems, space or missile defense mission applications, systems engineering processes, and performance assessment methods.
  • Ability to write code in Python and/or C/C++.
  • Ability to work effectively across multidisciplinary teams and the full development lifecycle.

Responsibilities

  • Support development of image and video processing algorithm solutions for space-based infrared systems.
  • Perform performance analyses of image and video processing algorithms for system-level trade studies, and support systems engineering trade studies, concept of operations development, and modeling and simulation efforts.
  • Work alongside embedded software and firmware teams that optimize and implement algorithms for space-based systems.
  • Develop and improve instrument documentation, processes, and test procedures.
  • Support concept of operations development and requirements analysis, decomposition, and generation at various system levels.
  • Support requirements traceability and develop test plans that cover requirements.
  • Support integration and testing of electro-optical/infrared systems and related hardware and software.
  • Support engineering in developing technical specifications, interface control documents, test plans and procedures, and testing conformance to specifications.
  • Support engineering in verifying compliance with requirements and validating performance behavior.
  • Use work experience to become a subject matter expert in the relevant area.
  • Define system requirements; support sensor and payload performance analysis; and mature technical solutions from concept through testing and validation.
  • Develop and assess detection and tracking approaches, support algorithm design and refinement, and ensure sensor calibration and verification activities meet mission performance objectives.
  • Analyze sensor system performance; develop and evaluate target detection and tracking algorithms; support calibration planning and execution; define verification methods and success criteria; and collaborate with hardware, software, modeling and simulation, and test teams on end-to-end system effectiveness.
  • Support technical reviews and risk reduction efforts, and translate mission needs into actionable engineering requirements.

Desired Qualifications

  • Experience in spacecraft, satellite, or other complex aerospace system development with responsibility at subsystem, system, or vehicle level.
  • Experience architecting, analyzing, developing, and integrating end-to-end systems in areas such as electro-optical/infrared, radio frequency, space payload, or spacecraft bus subsystems.
  • Experience with requirements management, interface control, system integration, verification and validation, and technical baseline management across the product lifecycle.
  • Familiarity with model-based systems engineering, requirements management tools, and configuration management processes.
  • Experience developing embedded software or firmware.
  • Experience with data analysis and/or modeling and simulation.
  • Experience with estimating and managing costs.
  • Familiarity with program management, cost account management, and integrated product teams.
  • Active security clearance.
  • Proficiency in Python.
  • Ability to work effectively across cross-functional engineering teams, communicate technical issues clearly to leadership, and support execution in a multi-site development environment.
