Flight Software Engineer

We are seeking a Flight Software Engineer to join our mission operations team in a role focused on developing high reliability embedded software systems for spacecraft flight operations. This position is central to ensuring mission success through robust flight software development, real-time system implementation, and hardware interface integration.

You will be an integral member of the flight software team working across embedded software development, telemetry and command systems, and CI/CD pipeline implementation-while contributing to flight-critical software applications that enable safe and efficient lunar mission execution.

Key Responsibilities

• End to end ownership of FSW subsystem - from requirements through verification and real time operations
• Architect, develop and maintain production-quality C code for embedded spacecraft flight software applications within the NASA cFS framework, implementing rigorous unit-level testing to ensure reliability of flight-critical systems.
• Design and implement real-time software systems for spacecraft operations, including command processing, telemetry generation, and hardware interface integration in memory-constrained environments.
• Work with embedded Linux systems (PREEMPT-RT), managing device trees, interrupt handling, scheduling, and system initialization to support high-reliability spacecraft operations.
• Own CI/CD pipeline development and maintenance, ensuring continuous integration and deployment of flight software with generated verification products.
• Collaborate with international engineering teams in Japan, Luxembourg and the U.S.
• Develop and maintain FSW operations procedures, technical documentation, and interface control documents to ensure operational readiness and mission assurance throughout the software development lifecycle.
• Support spacecraft operations as needed, monitoring telemetry, analyzing system performance, and providing flight software expertise during mission-critical phases.
• Work with vendors and internal stakeholders, clearly communicating technical requirements, progress and issues to both technical and non-technical audiences

Basic Qualifications

• 5+ years of working experience
• Proficiency in C for embedded applications with experience in high-reliability embedded software systems; direct experience with spacecraft flight software is ideal
• Experience with Python or similar scripting languages
• Proficiency with Git version control
• Working knowledge of Linux environments
• Experience with real-time system development and hardware interface integration
• Knowledge of software application design and implementation lifecycle, including initialization, command processing, telemetry generation, and unit-level testing
• Understanding of CI/CD pipelines and generated verification products

What Will Make You Stand Out

• Experience with embedded Linux systems including PREEMPT-RT Linux, scheduling, device tree configuration, and interrupt management
• Experience with Yocto and/or U-Boot development for embedded system setup
• Experience with Docker containerization
• Familiarity with NASA's Core Flight System (cFS) framework
• Familiarity with CCSDS protocols (TC/TM, CFDP, Space Packet Protocol) for space systems
• Experience with RTOS concepts including tasking, scheduling, and resource management
• Experience in telemetry and command management system design and implementation
• Experience with image processing protocols
• Experience working with memory-constrained environments and serial communication protocols
