Senior Flight Software Engineer

Observable Space•Los Angeles, CA

About The Position

We are seeking a highly-motivated and hands-on Senior Software Engineer to join our growing team. In this role, you’ll design, develop, and maintain flight software systems for spacecraft and telescope platforms. You’ll work with a multidisciplinary team of electrical, mechanical, optical, and software engineers to deliver reliable, fault-tolerant systems for ground-based and potential future space-based deployment.

Requirements

Bachelor’s degree in Computer Science, Computer Engineering, Aerospace Engineering, or equivalent.
5+ years of experience in software engineering, embedded systems, or systems-level development.
Strong programming skills in C/C++ or similar low-level languages.
Experience developing software for embedded or hardware-integrated systems.
Understanding of real-time systems, concurrency, and performance optimization.
Familiarity with communication protocols and networking fundamentals.
Strong debugging and problem-solving skills.
Effective communicator and collaborator.
Demonstrated passion for aerospace, robotics, or complex systems.

Nice To Haves

Experience developing flight software for spacecraft, satellites, or aerospace systems.
Familiarity with real-time operating systems (RTOS) or embedded Linux environments.
Understanding of fault-tolerant system design and reliability engineering.
Experience with hardware-in-the-loop (HIL) testing and simulation environments.
Familiarity with space communication standards (e.g., CCSDS).
Experience working in fast-paced, early-stage or startup environments.
Basic scripting or automation (Python, MATLAB) for testing or data analysis.

Responsibilities

Design and develop flight software for spacecraft and telescope systems, including command, control, and data handling (C&DH).
Build and maintain software that interfaces directly with hardware components, sensors, and onboard subsystems.
Architect systems for high reliability, fault tolerance, and long-duration autonomous operation.
Implement communication protocols for telemetry, command uplink/downlink, and system coordination.
Collaborate with electrical and hardware teams to ensure seamless integration between software and physical systems.
Support hardware bring-up, integration, and debugging at the hardware/software boundary.
Develop and implement fault detection, isolation, and recovery (FDIR) mechanisms.
Support system testing, including simulation, hardware-in-the-loop (HIL), and validation activities.
Participate in and contribute to design reviews (PDR, CDR, etc.) and internal documentation.
Provide engineering support during integration, testing, and system validation.
