You are skilled in space-based communication and interested in building intelligent space systems to modernize satellite operations. To succeed in this fast-paced, dynamic startup environment, you must be comfortable taking ideas from theory and turning them into successful deployments. As an network engineer, you will:

  • Develop network simulations for constellations of Earth-orbiting satellites and model communication interactions between satellites and ground-based assets.
  • Design and implement route optimization strategies for dynamic space-based mesh networks.
  • Perform network design, trade-off studies and assist in developing and defining protocols for Layers 2 and 3.
  • Provide communications network expertise to support data science and machine learning development.

Any experience related to the following would be of particular interest.

  • Discrete-event network simulators, such as NS3 or OPNET.
  • Knowledge of wireless SDWAN, MPLS, IPSec, and traffic shaping.
  • Experience implementing network protocols and routing algorithms, such as Dijkstra's, and Floyd-Warshall’s algorithms, as well as solving network flow optimization via mixed-integer programming.
  • Knowledge of QoS algorithms, cellular/satellite network protocols, and software defined networks.
  • Experience developing embedded flight software for satellite communication systems.
  • Skilled in troubleshooting and tuning of component hardware, software, networking and communications protocol problems.
  • Experience with systems integration and testing methodologies.
  • US Citizenship required.
  • Bachelor’s, Master’s degree, or Ph.D. in a relevant field: Aerospace, Electrical Engineering, Computer Science, or similar.
  • 4+ years of professional experience.
  • Proficiency with C/C++ or Python and object-oriented programming design.
  • Proficiency with Linux development environment.
  • Expertise in TCP/IP networking fundamentals, communication protocols, mesh networks, delay tolerant networks, and the Open Systems Interconnection (OSI) model
  • Comprehensive knowledge of communications systems, space systems, ground station networks, link budgets, radio frequency (RF) and optical laser communications
  • Ability to communicate complex data in a simple, actionable way
  • Ability to work in a multidisciplinary team and work collaboratively on complex tasks.
  • Outstanding analytical and problem-solving skills.
