Job Description:

As a System Integration Test Engineer, you will integrate and verify Shield AI's Hivemind mission autonomy software directly on Autonomous Collaborative Platform (ACP) flight hardware. You will serve as the hands-on technical bridge between autonomy algorithms and physical aircraft systems, working across Shield AI and aircraft platform vendors to verify system interfaces, validate edge compute performance, and resolve integration issues before flight testing. 

You will drive integration across Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) environments, both in Shield AI's internal laboratories and on-site at platform vendor integration facilities (including SIL, HIL, and iron bird test benches). You will turn high-level program objectives into executable integration plans, schedules, and test cards, systematically uncovering interface gaps early and formulating technical solutions to close them. This is an essential, high-impact role for an engineer who excels at the intersection where complex mission software meets real aircraft avionics and hardware. 

What you'll do:

• Integrate Mission Autonomy on ACP Hardware: Deploy, integrate, and verify Hivemind mission autonomy software with actual ACP software and hardware in Shield AI and platform vendor SIL and HIL labs. 

• Develop Test & Integration Plans: Develop detailed integration test plans, test cards, schedules, and objective success criteria across lab, ground, and flight test phases. 

• Identify & Resolve Integration Gaps: Proactively identify architectural, interface, protocol, timing, and hardware/software gaps early; formulate concrete gap-closure plans, risk mitigations, and technical workarounds alongside Shield engineering and platform partners. 

• Coordinate Joint Vendor Lab Execution: Partner directly with aircraft OEMs and platform vendors to coordinate lab readiness, align entry/exit criteria, deconflict bench time, and co-execute joint integration campaigns. 

• Conduct Hands-On Lab Triage: Execute integration tests, configure test benches, and lead real-time troubleshooting of multi-system anomalies 

• Drive Test Automation & Tooling: Coordinate across engineering teams to design and build test automation and simulation scripts to accelerate development 

• Gate Flight Readiness & Support Flight Test: Enforce empirical test entry/exit criteria to gate delivery to aircraft ground and flight test; support flight test preparation, configuration validation, real-time troubleshooting, and post-flight data analysis. 

• Support travel to test sites, customer events, and integration activities as required 

Required qualifications:

• Typically requires 5+ years of relevant experience with a Bachelor's degree in Aerospace, Electrical, Computer, Mechanical, Systems Engineering, or related technical field, or 3+ years with a Master's degree. 

• Lab & Hardware Integration: Demonstrated experience in system integration and test, including SIL, HIL, simulation, and flight test environments. 

• Test Planning & Documentation: Proven ability to author clear, comprehensive integration test plans, procedures, and test cards, and translate test results into actionable engineering findings and gap closure roadmaps. 

• Troubleshooting & Analysis: Strong experience troubleshooting complex system interfaces using telemetry, logs, packet capture tools (e.g., Wireshark), or hardware diagnostic equipment. 

• Scripting & Linux: Proficiency with Linux operating systems and scripting languages (Python preferred) for test automation, data analysis, and hardware bench interfacing. 

• Communication & Organization: Highly organized and methodical, with the ability to organize integration tasks, track dependencies, and coordinate work across distributed engineering teams and external partners. 

• Travel Flexibility: Willingness and ability to travel periodically to platform vendor facilities and flight test locations as program needs require. 

• Clearance & Citizenship: Ability to obtain and maintain a U.S. DoD SECRET security clearance; U.S. citizenship required. 

Preferred qualifications:

• Autonomous & Uncrewed Systems: Experience with Autonomous Collaborative Platforms (ACP), Collaborative Combat Aircraft (CCA), UAS (Group 4/5), or military aircraft mission systems. 

• OEM / Prime Contractor Experience: Experience working directly inside aircraft manufacturer or defense prime contractor integration labs (e.g., Boeing, Northrop Grumman, Lockheed Martin, General Atomics, Anduril). 

• Open Architecture Standards: Familiarity with open systems architectures such as Open Mission Systems (OMS), Universal Command and Control Interface (UCI), and Modular Open Systems Approach (MOSA). 

• Middleware & Frameworks: Experience with inter-process communication and messaging middleware (e.g., DDS, ROS/ROS2, ZeroMQ, gRPC). 

• Safety & Airworthiness: Understanding of airworthiness processes, safety-of-flight standards, or software assurance guidelines (e.g., DO-178C, DO-254, MIL-STD-882E). 

• Active Clearance: Active DoD SECRET or TOP SECRET clearance. 

What success looks like:

• Mission autonomy and aircraft hardware/avionics operate reliably and deterministically together in representative SIL and HIL labs well before aircraft ground and flight testing. Integration gaps and interface discrepancies are surfaced and resolved early, configurations and master test schedules are transparent and aligned across vendors, and rigorous lab test results provide the high-confidence empirical evidence needed to clear the aircraft for flight.
