Redwire Space Missions LLC, in Jacksonville, FL is seeking a Staff
, Embedded Software Engineer to join our team. In this position, you will be responsible for the design, development, integration, and testing of embedded software for spacecraft avionics and mission systems. This role includes ownership of software modules throughout their lifecycle, from requirements and architecture through coding, verification, and delivery. You will work closely with systems, electrical, and test engineering teams to implement reliable flight and ground software for mission success.

• Develop, integrate, and maintain embedded software for mission‑critical spacecraft subsystems and testbeds.
• Translate system and subsystem requirements into software architectures, designs, and implementations.
• Implement algorithms for command and data handling (C&DH), guidance, navigation & control (GNC), fault detection, power control and distribution, and communications.
• Develop device drivers, middleware, and real‑time applications for spacecraft avionics hardware.
• Perform unit, integration, and system‑level software testing, including hardware‑in‑the‑loop (HIL) environments.
• Support software verification and validation campaigns, including formal reviews and demonstrations.
• Collaborate with hardware engineers to define interfaces and ensure correct hardware/software integration.
• Support anomaly investigation, root‑cause analysis, and corrective actions for software‑related issues.
• Develop documentation including requirements, design descriptions, interface control documents (ICDs), and test reports.
• Ensure compliance with aerospace software quality standards and configuration management processes.

• Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or related field.
• 8+ years of professional experience in embedded software development (aerospace or defense preferred).
• Proficiency in C and C++ for embedded systems; knowledge of Python or MATLAB for analysis and testing.
• Experience with real‑time operating systems (RTOS) such as VxWorks, RTEMS, FreeRTOS, or similar.
• Familiarity with spacecraft avionics interfaces and protocols (e.g., MIL‑STD‑1553, CAN, Space Wire, RS‑422, Ethernet).
• Experience developing device drivers and low‑level hardware/software integration.
• Experience with version control systems (Git, SVN) and issue‑tracking tools (JIRA, Confluence).
• Ability to work in cross‑functional teams within an agile execution framework and communicate effectively with hardware and systems engineers.
• Must have the ability to obtain DOD security clearance.
• Some limited travel.

• Experience with SoC/FPGA system design for hardware interfaces such as UART, SPI, I2C, CAN, Camera Sensor Interface (CSI) & Ethernet.
• Strong debugging and troubleshooting skills with embedded targets.
• Strong problem‑solving, troubleshooting, and fault isolation skills.
• Demonstrated leadership in mentoring junior engineers and contributing to software architecture decisions.
