Job description

Software Systems Engineer Staff

Redwire Space Missions LLC is seeking a Software Systems Engineer Staff to join our team in Littleton, CO. This role is critical to the success of our spacecraft programs and is ideal for an engineer who thrives at the intersection of software, hardware, and systems engineering.

You will drive system-level architecture, guide software requirements development, lead integration activities, and ensure seamless interaction between software modules, avionics, networks, and spacecraft subsystems. This position requires a proactive engineer with strong technical judgment, the ability to lead cross‑functional efforts, and deep experience across the full space systems lifecycle.

Responsibilities

• Lead end‑to‑end development of software‑related system requirements, system behaviors, functional decomposition, software architectures, FSW high‑level designs, and V&V planning
• Ensure integrated performance of flight software across spacecraft subsystems including Command & Data Handling, Guidance/Navigation/Control, Electrical Power, and RF Communications
• Develop software integration strategies, including simulation‑based testing, hardware‑in‑the‑loop testing, test readiness planning, execution oversight, and closure
• Coordinate and contribute to major technical reviews including SRR, PDR, CDR, TRR, and inform verification activities for RVCMs/RVTMs
• Define and maintain software‑to‑hardware and software‑to‑software interfaces; develop and manage Interface Control Documents and ensure cross‑functional alignment
• Define FDIR / autonomy frameworks and designs for space vehicles to include cross‑coordination with customers on mission operation solutions
• Support the creation and maintenance of test infrastructure, including modeling environments, test automation frameworks, software integration labs, and EGSE supporting software and system‑level verification
• Provide technical management and oversight of vendor‑provided/GFE software, ensuring software products meet mission requirements
• Produce clear, high‑quality technical documentation including requirements artifacts, procedures, test plans, and engineering reports
• Provide technical leadership, mentoring, and daily guidance to software and multidisciplinary engineering teams throughout the development lifecycle
• Contribute to system trade studies, design decisions, performance evaluations, and risk management activities for flight software and its interaction with spacecraft hardware
• Drive system‑level thinking that considers performance, reliability, maintainability, and long‑term lifecycle management of flight software

Ideal Experience

• Bachelor's, Master's, or Ph.D. in Software Engineering, Computer Engineering, Systems Engineering, Aerospace Engineering, or a related field
• Minimum of 8+ years of engineering experience in the space industry or in embedded/realtime systems
• Strong understanding of spacecraft systems engineering processes including requirements development, architecture design, integration & test, and mission operations
• Experience integrating software with embedded hardware, avionics, networks, or complex distributed systems
• Demonstrated ability to lead technical teams and collaborate across hardware and software disciplines
• U.S. Citizenship with the ability to obtain a DoD Security Clearance

Desired Skills

• Advanced degree in Software Engineering, Systems Engineering, Computer Engineering, or related discipline
• 5-8 years of experience in spacecraft engineering or embedded flight software development
• Experience supporting NASA/DoD lifecycle reviews (SRR, PDR, CDR, etc.)
• Proficiency with requirements management tools such as JAMA or DOORS
• Experience with MBSE, SysML, or tools such as CAMEO Systems Modeler
• Background in spacecraft software systems, RTOS‑based development, simulation frameworks, or hardware/software integration labs
• Active DoD Security Clearance
• Experience with spacecraft Command & Data Handling, avionics, or other subsystem software interfaces
• Broad systems engineering skill set and the ability to lead software integration across multiple spacecraft subsystems
