What You'll Do
- Serve as the technical lead and primary engineering authority for spacecraft simulators across the full program lifecycle.
- Define and communicate simulator system architecture, ensuring cohesive integration of software, hardware, and spacecraft subsystem models.
- Lead real-time simulation development, model-based design, and HIL integration activities.
- Chair technical reviews and internal design discussions.
- Mentor and guide small teams of systems and software engineers.
- Design, develop, and implement real-time simulations of spacecraft and space vehicle subsystems.
- Perform full software lifecycle activities: requirements, architecture, design, coding, integration, test, and documentation.
- Develop and validate requirements, verification plans, and sell-off artifacts for deliverables.
- Identify technical risks early and drive mitigation strategies to ensure simulator performance and reliability.
- Integrate flight-like hardware, avionics interfaces, and embedded systems into simulation environments.
- Act as the primary technical interface to spacecraft programs, subsystem leads, and customer engineering teams.
- Present simulator design and technical status at major program reviews.
- Support program-facing activities by providing technical inputs for CAM/EVMS, proposals, and contract changes.
- Understand customer needs and proactively shape simulator capabilities to support mission success.
- Drive adoption of modern DevSecOps, containerization, and secure software development practices.
- Contribute to department-wide risk, opportunity, and technology development initiatives.
- Support proposal development and technical planning for new missions.
What We're Looking For
- BS degree or higher in Engineering or a related technical field plus 10 or more years of related experience.
- A current, active TS/SCI security clearance with the ability to obtain and maintain a TS/SCI Polygraph.
- Hands-on experience developing real-time simulations, model-based designs, and HIL systems.
- Proficiency with Matlab/Simulink, including auto-code generation (Embedded Coder, Simulink Coder, MATLAB Coder).
- Software engineering background with C/C++ and experience in Python, Ruby, Rust or similar languages.
- Experience with real-time operating systems (Linux, VxWorks) and embedded systems.
- Knowledge of spacecraft or space hardware systems, including avionics interfaces and subsystem modeling.
- Experience integrating complex systems across space and ground segments.
- Experience developing and deploying OCI-compliant containers.
- Proficiency with Podman and Kubernetes for container orchestration.
- Hands-on experience with GitLab DevSecOps pipelines.
- Familiarity with secure software development lifecycle practices for high-security environments.
- Demonstrated ability to lead small engineering teams and mentor junior engineers.
- Excellent communication skills for articulating complex technical concepts to diverse audiences.
- Proven ability to drive technical decisions and maintain engineering rigor under schedule and mission pressures.
