Mid-Level Systems Engineer with Security Clearance

Mount Indie is seeking a Systems Engineer who thrives in innovative, integration-driven environments and is passionate about reducing uncertainty early in the development lifecycle. This role supports the definition, design, and de-risking of complicated tactical communication systems composed of hardware, software, networking, and RF components.

Key Responsibilities Define

• Contribute to refinement of mission intent and system scope
• Surface assumptions and risks early in development
• Support decomposition of customer requirements into system-level behaviors Design
• Support system architecture and interface definition
• Create and maintain system diagrams and interface documentation
• Participate in trade studies and cross-discipline collaboration De-risk
• Support modeling, simulation, and integration experiments
• Assist in planning and executing integration and test events
• Capture expected vs. observed behavior during testing
• Support hypothesis testing through integration activities and capture expected vs. observed system behavior
• Surface deviations that invalidate architectural assumptions and feed them back into system refinement Deliver
• Support formal integration and system verification events
• Ensure system behavior aligns with defined mission intent
• Assist in documenting expected vs. observed outcomes
• Participate in root cause analysis and corrective action planning
• Help maintain traceability from mission threads through validation artifacts Requirements
• Bachelor's Degree in Engineering or related technical field or equivalent experience
• 4-6 years of experience in complicated system development
• Experience integrating hardware, software, and networking systems
• Demonstrated ability to work in iterative, fast-paced development environments where requirements and architecture evolve as uncertainty is reduced
• Experience integrating across hardware, software, networking, and RF domains in environments with shifting technical constraints
• Experience working within a hypothesis-driven development environment where architectural assumptions are progressively tested through integration and test events
• Ability to link detailed execution work to higher-level mission intent and architectural hypotheses
• Active U.S. Secret Clearance Preferred Qualifications
• Experience with SysML, Cameo, or MBSE practices
• Experience supporting modeling and simulation activities
• Experience with requirements management tools (e.g., Jama, DOORS) and maintaining bidirectional traceability between requirements and validation artifacts
• Familiarity with issue tracking and work management tools (e.g., Jira)
• Experience working within digital engineering or model-informed development environments
• Familiarity with agile development environments
