System Performance Modeling Developer

Algorithm And Network Simulation Engineer

Logos Space is a Low Earth Orbit (LEO) satellite system purpose-built to serve the connectivity needs of the commercial enterprise users and government users. We will help fill an important gap in the market, providing resilient, high-performancesatellite-based connectivity services to enterprise and government customers worldwide. Business customers have contracts with agreed-upon performance standards for their broadband, and Logos will build these capabilities into the system from the beginning. Speed and reliability are the foundation of the system. Logos is designed to extend cloud and data center network connectivity anywhere in the world to fixed, seaborne, and airborne terminals.

The Networking team at Logos Space is responsible for ensuring the success of our network through development of a software defined networking, performance monitoring and other components of the ground segment. It is also responsible for collaboration with other aspects of the spacecraft design, such as the RF, power management and other aspects. This network will simultaneously offer services at Layer 2, 2.5 and 3 to enterprise customers, which is a unique service for which Logos will have to develop the methodology to manage flows at an enterprise level of assurance. This position will evolve the tools to understand the impact of this development, starting with conceptual framework, and eventually evolving to discrete event simulation at the message level, and ultimately to a "digital twin" of the deployed system.

As an Algorithm and Network Simulation Engineer, you will play a crucial role in the design, optimization, and validation of our cutting-edge hybrid space and terrestrial network. You will be responsible for developing sophisticated simulation models and algorithms to analyze performance, evaluate emerging technologies, and optimize network behavior across this complex environment. This is an exceptional opportunity to drive core innovation within our network architecture.

You should be prepared to work and thrive in a fast moving environment where you are comfortable taking vague design ideas and turning them into tangible hardware ready for test and flight. We are seeking engineers who love to solve hard problems!
