Work in Linux environments (e.g., RHEL, CentOS) and containerized frameworks (e.g., Kubernetes, Docker, Singularity).
Develop and troubleshoot software on embedded systems and real-time targets.
Support the creation of technical documentation, including RFP packages and interface specifications.
Apply digital engineering and model-based systems engineering (MBSE) principles.
Contribute to hybrid cloud software deployments and edge-to-cloud integrations.
Collaborate within open architecture consortiums and support compliance with modular standards.
Participate in cross-domain engineering reviews and integration events.

Qualifications

Required
