At Orbital Paradigm, we design, develop, manufacture, and operate reusable orbital logistics systems. Our spacecraft perform multiple orbital mission profiles and return safely to Earth through hypersonic atmospheric reentry and landing with pinpoint accuracy for rapid refurbishment and reuse.

Role Description

We are looking for a Junior to Mid-Level Embedded Software Engineer to join our embedded software team to support the development, integration, testing, and qualification of embedded software and firmware for our reusable orbital logistics vehicles.

The role focuses on flight software, firmware, real-time operating systems, low-level interfaces, EGSE, and embedded software verification and validation. The engineer will work closely with avionics, GNC, systems, and AIT teams to develop, test, debug, and qualify reliable software for mission-critical spacecraft functions.

Key Responsibilities
- Develop embedded software and firmware for spacecraft avionics and flight systems.
- Implement real-time software using RTOS-based architectures.
- Develop low-level drivers,



communication interfaces, and hardware abstraction layers.
- Support integration of embedded software with on-board computers, sensors, actuators, and avionics hardware.
- Implement and test communication protocols and data interfaces between spacecraft subsystems.
- Support software integration, debugging, and validation on target hardware.
- Develop and maintain software test procedures, unit tests, integration tests, and verification reports.
- Support SIL, HIL, EGSE, and system-level test campaigns.
- Contribute to software requirements definition, architecture, design documentation, and interface control documentation.
- Support debugging and root-cause analysis of embedded software, firmware, timing, and hardware-interface issues.
- Work with avionics, GNC, systems, and AIT teams to ensure software meets mission, safety, and reliability requirements.
- Contribute to design reviews, test rea
