Role Summary

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.

Key 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.

Basic Qualifications

• 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.

Preferred Qualifications

• 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.

What We Offer

• Competitive Compensation – A salary package aligned with industry standards and your experience.

• Equity Opportunities – Take part in our success with stock options.

• Flexible Work Environment – Enjoy working from our office or in a hybrid work setup with the flexibility to work remotely part of the week. We require a minimum of 3 days per week in our office to support collaboration and team culture. (LA Office only)

• Unlimited PTO – Take the time you need with our flexible, trust‑based vacation policy, including paid holidays. We encourage everyone to rest, recharge, and take care of themselves.

• Health & Wellness – Comprehensive medical, dental, and vision coverage with 100% of the premium paid by the employer for employees.

• Cutting-Edge Tools – Get access to the latest hardware and software you need to do your best work.

• Mission-Driven Culture – Be part of a team working on meaningful challenges with real‑world impact.
