What are the responsibilities and job description for the Spacecraft Flight Software Engineer position at Quantum Space?
Salary: $85,000 to $135,000Who Were Looking ForQuantum Space is redefining mobility and autonomy in cislunar and geostationary space. Our Ranger spacecraft deliver high delta-V and on-orbit maneuverability that enable customers to access, operate, and persist in orbits previously out of reach. Were building the infrastructure, vehicles, and operational expertise that connect and protect assets across the EarthMoon system.We are seeking a Flight Software Engineer to design, develop, integrate, and test embedded software that powers our spacecraft and payload systems. You will work across subsystem teams to implement flight behaviors, command sequences, and on-orbit functionality that directly impact mission success. This role is ideal for an engineer who thrives in a fast-paced, iterative environment and who enjoys working at the interface of software, hardware, and operations.Where Youll Make an ImpactDevelop flight and payload software for embedded spacecraft systems running VxWorks and Linux.Debug and integrate software with hardware subsystems across a variety of communication interfaces and protocols.Collaborate with avionics, payload, propulsion, and GNC leads to implement subsystem behaviors in flight software.Work with mission operations and ground software teams to design scheduling logic, command sequences, and autonomous behaviors.Support hardware-in-the-loop (HIL) testing, system integration, and functional verification of spacecraft software.Document software behaviors, interfaces, and workflows to ensure cross-functional alignment across engineering teams.Operate effectively in a schedule-driven, rapid development environmentWhat It TakesBS in Computer Science, Computer Engineering, or related field3 years of experience with C or another object-oriented programming languageProficiency in Python for scripting, testing, and automationStrong experience working in a Linux development environment, including but not limited to:Shell scripting (bash)Networking/IPSerial/UART interactionsSystem-level debuggingExperience with Git and Git-based workflows such as GitLabFamiliarity with Agile software development processesAbility to rapidly understand, navigate, and contribute to a large, previously developed codebaseNice to Have5 years of C development experienceExperience developing flight software or other spacecraft-related software (ground tools, test frameworks, payload apps)Background in embedded systems developmentExperience with Docker or other containerization toolsFamiliarity with common spacecraft interfaces such as I2C, RS-422/485, LVDS, SpaceWire, MIL-1553, EthernetExperience with Rocket Lab MAX FSWHands-on experience with VxWorks or other real-time operating systems (RTOS)What Youll GetOwnership Build and shape the core software that executes on orbit and drives our mission capabilities.Impact Contribute directly to spacecraft behavior, autonomy, and mission execution.Innovation Work across hardware, software, and operations to develop the next generation of on-orbit systems.Growth Expand your technical depth in embedded systems, flight software, and spacecraft operations.Compensation Competitive salary, equity, and comprehensive benefits including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity sharing.Additional RequirementsTo comply with U.S. Government space technology export regulations, including ITAR, applicants must be a U.S. citizen, lawful permanent resident, protected individual per 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.Apply now.
