Key Responsibilities:

• Derive requirements for embedded flight software in C/C++ for spacecraft systems
• Support development planning with FSW management and vehicle systems engineering activities in a cross‑functional team
• Integrate software with hardware components (on‑board computers, radios, payloads) in HITL and simulated environments
• Develop and execute test strategies (unit, integration, system, and mission‑level testing)
• Support on‑orbit operations, debugging, and anomaly resolution
• Contribute to software architecture, requirements, and interface definitions
• Collaborate across platform, applications, mission ops, and hardware teams

Required Qualifications:

• Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or related field
• 2+ years of experience in embedded software development
• Proficiency with Atlassian JIRA
• Prior experience with software development ticket management and requirement management frameworks
• Experience debugging hardware/software integration issues
• Proficiency in C/C++ and Git/Gitlab (or other code repository management tooling)
• Must have the ability to independently navigate source code, in order to correlate requirements, developed capabilities, and human interfaces for operations
• Must be clearance eligible and able to maintain an active Secret Clearance or higher
• Love space!

Preferred Qualifications:

• Familiarity with networking protocols (TCP/IP, UDP, routing concepts)
• Experience with spacecraft, aerospace, or safety‑critical systems
• Experience with embedded Linux systems (drivers, networking, system‑level debugging)
• Knowledge of real‑time systems and deterministic software design
• Familiarity with CCSDS, DTN, or space communication protocols
• Understanding of cybersecurity principles (secure boot, signing, key management)
