They are seeking a
Staff Flight Software Engineer . You'll serve as a primary contributor to the flight software design, working to shape system interfaces and component interactions. Responsibilities
Develop & Integrate : Implement embedded flight software modules in C++ on RTOS or space-grade frameworks; carry features from concept through flight-ready validation. System Validation : Plan and execute comprehensive hardware/software integration tests, including fault-injection scenarios and performance benchmarking. Cross-Functional Collaboration : Partner with hardware engineering, GNC, and operations to define interfaces, manage fault conditions, and implement mitigation workflows. CCSDS TT&C Integration : Develop and validate CCSDS-compliant Telemetry, Tracking & Command (TT&C) subsystems—implement frame assembly/disassembly, packetization, CRC/error-control coding, and end-to-end link workflows. Optimization & Reliability : Profile and tune software for CPU, memory, and I/O efficiency; contribute to FDIR logic and scheduler enhancements to maximize on-orbit reliability. Mentorship & Best Practices : Coach mid-level engineers through design reviews and code walks; promote coding standards, automated testing, and CI/CD pipelines. Documentation & Tooling : Produce clear technical artifacts - ICDs, test plans, runbooks - and help build digital tools for telemetry analysis and on-orbit diagnostics. Requirements
Experience: 8+ years developing C/C++ embedded software on RTOS or space-grade frameworks (cFS, F', TASTE, etc.). Integration & Testing: Proven track record executing full-system hardware/software validation and fault-injection test campaigns. Protocols & Interfaces: Deep expertise with RS-422/485, Ethernet, I2C, or similar communication buses in embedded environments. Real-Time Systems: Solid understanding of real-time scheduling, FDIR principles, and performance profiling under resource constraints. Communication: Excellent written and verbal skills for cross-team collaboration and technical documentation. CCSDS Expertise: Hands- on experience implementing CCSDS Telemetry (TM) and Telecommand (TC) packet standards, including header/payload formats, Virtual Channel multiplexing, and CRC/error-control procedures Preferred Experience
Hands- on experience with on-orbit operations, telemetry analysis, or spacecraft HIL testbeds. Background in aerospace or other safety-critical industries. Advanced degree in Computer Science, Electrical Engineering, or related field. Additional
$190K - $230K, Salary may vary with experience Incentive Equity Medical, Dental and Vision Insurance PTO 401k U.S. citizenship or lawful permanent residency is required (22 C.F.R. § 120.15 compliance).
