About the role

  • The Navigation team at Logos Space is assisting in developing a constellation-level software framework to model, test, validate, and operate our proliferated LEO constellation as a dynamic space network.
  • The framework will support engineering trades, network validation, operational rehearsals, anomaly reconstruction, "what-if" analysis, and stakeholder-facing visualization.
  • In this role, you will develop the software infrastructure that turns navigation products, spacecraft telemetry, predicted ephemerides, network configuration, and mission constraints into a usable constellation-level representation of system behavior.

Responsibilities

  • Develop and maintain C++ and Python software for the Logos constellation-level software framework.
  • Build constellation-scale infrastructure that combines spacecraft ephemerides, mission geometry, timing behavior, link availability, ground assets, network topology, routing state, and operational constraints.
  • Support modeling and testing of software-defined networking behavior, including routing state, link-state changes, handovers, path availability, latency, throughput constraints, degradation modes, and network recovery behavior.
  • Build scenario generation tools for constellation deployment, nominal operations, planned maneuvers, ground contacts, network outages, spacecraft degradation, regional demand changes, maintenance windows, and mission-critical "what-if" cases.
  • Develop capabilities that allow the team to simulate future constellation behavior, reconstruct past events, compare predicted and observed behavior, and support anomaly investigations.
  • Develop scalable simulation and data-processing infrastructure capable of handling many spacecraft, many links, long time horizons, and repeated scenario sweeps.
  • Build validation infrastructure, including unit tests, integration tests, regression tests, deterministic replay, scenario comparison tools, performance benchmarks, and independent cross-checks against trusted analysis tools.
  • Support integrated test campaigns, operational rehearsals, constellation performance analysis, commissioning, flight-data investigations, and anomaly response as needed.
  • Logos Space is building a proliferated Low Earth Orbit (pLEO) constellation to deliver resilient, high-performance connectivity to enterprise and government users worldwide.

Requirements

  • Bachelor's degree in Aerospace Engineering, Computer Science, Electrical Engineering, Applied Mathematics, Physics, or a related STEM field, or equivalent practical experience.
  • Proficiency in modern C++ and/or Python for production software development.
  • Working knowledge of orbital mechanics, spacecraft ephemerides, coordinate frames, time systems, mission geometry, or similar dynamic system modeling fundamentals.
  • Experience modeling or analyzing network behavior, routing, link availability, latency, throughput, topology changes, or distributed system performance.
  • Experience with Linux-based development environments, Git, and automated testing.

Nice to have

  • Experience with software-defined networking, routing protocols, link-state systems, network orchestration, traffic modeling, or distributed network control planes.
  • Experience with visualization frameworks.
  • Experience with astrodynamics and mission simulation tools.
  • Experience integrating simulation environments with flight software, ground software, network testbeds, hardware-in-the-loop systems, or mission operations systems.
  • Familiarity with CCSDS data formats, spacecraft command and telemetry systems, mission planning interfaces, or ground-to-flight software interfaces.
  • Even if you don't meet every qualification, we encourage you to apply.
  • We value strong fundamentals, sound judgment, and growth potential, and we know great candidates do not always match every item on a job description.
  • Logos Space is an equal opportunity employer and values creativity, curiosity, and diverse perspectives.

Company info

  • As part of that effort, the Navigation team is designing and building the software and infrastructure for spacecraft timing, astrodynamics, maneuver planning, orbit determination, and related navigation workflows used across flight and ground systems.
