- Participate in Integrated Product Teams (IPTs) to design new capabilities based on development and operational considerations.
- Identify, assess, and mitigate risks associated with system development, ensuring compliance with risk management plans and stakeholder requirements.
- Communicate complex systems engineering concepts, progress, risks, and mitigations to executive leadership to enable informed decisions.
- Preserve system baseline integrity via change control, requirements traceability, and verification across the lifecycle.
- Support the planning, test analysis, and system definition approval as part of Government authorization processes.
- Provide technical direction for development, engineering, interfacing, integration, and testing complex hardware/software systems, including requirements analysis, system architecture, and end-to-end flow analysis.
Qualifications:

- Excellent communication skills, with the ability to convey technical concepts to non-technical stakeholders.
- Experience in maintaining system integrity and supporting certification and accreditation processes.
- Familiarity with the system engineering life cycle, including requirements, design, development, integration, testing, and deployment.
- Experience scripting in Python, PowerShell, or Bash to automate analysis, integration, and test activities.
- Experience with workload/project management tools (e.g., Jira).
- Experience with Git-based version control and continuous integration/continuous deployment (CI/CD) pipelines (e.g., GitHub or GitLab) to support automated build, test, and verification activities.
