At NewOrbit Space, our mission is to engineer the lowest orbiting satellites on Earth to rapidly advance global connectivity and insight. We are currently building satellites that can operate at an altitude of just 200 km - one-third that of conventional satellites. Your role You’ll architect and implement the flight-software stack and push code from bench tests to on-orbit updates. You’ll ensure each satellite runs autonomously and safely, turning in-orbit data into actionable ground insights so every subsystem meets its mission marks. You'll have a huge influence on the direction of the software and system development of our satellite. Key Responsibilities Own the on-board flight software stack — design, implement, and test real-time Rust/C/C++ on RTOS or Embedded Linux, from BSP/bring-up to application logic. Build subsystem software interfaces — define and implement ICDs/APIs and drivers/middleware for subsystems.; integrate over common buses (CAN, UART, SPI, I2C, SpaceWire as applicable); handle timing, concurrency, and fault containment at boundaries. Ship code from review to orbit — push through CI/CD, support launch, and deliver over-the-air updates during operations. Build prototypes, simulations, and telemetry analysis tooling — develop SIL/HIL rigs and mission sims; instrument systems; analyze telemetry to validate designs and quantify CPU/memory/bandwidth/power constraints. Build autonomous FDIR logic — detect, isolate and recover from SEUs, sensor drop-outs and thermal excursions without ground intervention. Design the command & telemetry pipeline — implement end-to-end commanding, telemetry, and event logging, transforming CCSDS frames in orbit into MQTT topics and cloud dashboards on the ground. Fundamental Requirements Proven experience of writing software for previously flown spacecrafts Experience building production embedded or real-time systems in C/C++ or Rust on RTOS or Embedded Linux. Strong understanding of standardized space communication protocols such as CCSDS and on-board buses such as CAN, I2C, UART, SPI and SpaceWire. Familiarity with ECSS and NASA flight software development tools Experience taking code through unit, integration & HIL tests and shipping via CI/CD (exposure to MISRA-C or ECSS a plus).
