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
