We are seeking a Systems Engineer with strong software development expertise to support the development of command and control software for a cutting-edge application.

  • Design, develop, and implement command and control software for LIDAR payload systems
  • Interface with GPS/GNSS equipment, scanning mirrors, lasers, and laboratory devices (e.g., time delay generators, oscilloscopes)
  • Ensure precise timing synchronization and high-rate data acquisition across subsystems
  • Develop remote operations capabilities, including subsystem command execution and telemetry return
  • Program across Windows and Linux environments, with focus on performance, reliability, and scalability
  • Document algorithms, interfaces, and system designs through UML diagrams and software ICDs
  • Collaborate with engineers and scientists on integration, testing, and field experimentation

Qualifications:

  • Must hold an active DoD Secret security clearance (Top Secret preferred)
  • Bachelor's or Master's degree in Computer Science, Computer Engineering, Software Engineering, Electrical Engineering, or related field
  • 3–5 years of engineering experience with software development for hardware-integrated systems
  • Proficient in programming in both Windows and Linux environments
  • Proficiency in C, C++, or Rust (assembly and high-performance computing experience a plus)
  • Experience with Python; Flask experience a plus
  • Skilled in embedded systems programming (microcontrollers; FPGA experience a plus, experience interfacing with laboratory measurement equipment is a plus)
  • Experience with laboratory equipment integration and data acquisition
  • Proficient in object-oriented programming, multithreaded/parallel programming (OpenMP, CUDA, or OpenCL a plus)
  • Familiarity with GUI/UI/UX development and networking protocols (REST APIs, WebSocket)
  • Experience documenting and communicating algorithms/code through UML diagrams and software ICDs
  • Experience with networking/network programming a plus (e.g. experience working with REST APIs or WebSocket)
  • Strong communication skills for technical documentation and cross-team collaboration
  • Desired Skills: Experience with SIMD/MIMD parallel programming
  • Experience in high-throughput data recording and storage optimization
  • Prior work with remote command and control of scientific payloads
