Lead, Flight Software 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-performance satellite-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.

Logos is led by a team of highly experienced engineers with proven track records in the networking and satellite industries.

Position Summary, Responsibilities, & Qualifications

Logos Space Services is seeking a Lead, Flight Software Engineer to develop the future of resilient, high-performance space networking technology. We are building networking infrastructure in orbit. You will architect the core flight software for our mega constellation and lead the team that develops it from the ground up.

This isn't a "maintenance" role. You will be responsible for the full lifecycle of the software stack—from initial framework design to ensuring deterministic performance under the physical constraints of a space environment. We need someone who has shipped mission-critical flight software and understands how to build for reliability.

Responsibilities

• Greenfield Frameworks—Design and implement a modular, high-performance application software framework in Modern C++, specifically optimized for multi-core ARM or RISC architectures.

• Design and develop on-board,real-time logic for network orchestration, state control, autonomous system recovery to ensure uninterrupted enterprise connectivity.

• Optimize memory utilization and determinism for high-throughput processing tasks across PREEMPT_RT, RTOS, or bare-metal targets.

• Implement and optimize high-performance data bus layers (e.g., MQTT) to facilitate seamless interprocess orchestration across distributed subsystems.

• Hardware-software integration across typical space payload interfaces—serial, CAN, Ethernet, etc

• Architect the implementation of an automated "requirements-as-code" verification strategy, utilizing Hardware-in-the-Loop (HITL) simulators and CI/CD pipelines to ensure a flight-ready software baseline at all times.

• High-Fidelity Simulation: Architect software emulations of complex subsystems to enable rapid iterative testing and validation of mission-critical network logic.

Basic Qualifications

• 10+ years in aerospace or high-reliability embedded flight software systems, with a track record of taking complex systems from initial architecture through successful on-orbit operations.

• C++ Expert: Master-level proficiency in C and Modern C++ within multi-threaded, resource-constrained ARM or RISC environments.

• Deep understanding of distributed system architecture, software-defined networking, and middleware performance tuning.

• Modern Engineering Toolstack: Expert-level command of DevOps & automation tools, CMake, Docker for environment parity, and the GNU toolchain.

Preferred Qualifications

• Master’s degree in Computer Science, Computer Engineering, or Electrical Engineering.

• Experience with high-speed networking hardware interfaces (e.g., Ethernet).

• Familiarity with Software Defined Networking (SDN) and routing protocols.

• Ability to obtain and maintain a U.S. Government Security Clearance.
