Subject-Matter Expert Avionics Engineer - Active TS/SCI

Position Summary: Serve as the cornerstone technical authority for integrating open-architecture airborne nodes linking warfighters to decision-quality data at the tactical edge. As the program's Avionics Engineering Subject Matter Expert (SME), you will lead avionics integration of chassis, Type-1 crypto, SATCOM apertures, and OMS/UCI software with multiple aircraft avionics suites during Major Release-ensuring airworthiness, mission effectiveness, and robust digital-thread fidelity.Essential Job Functions:
Architecture & Design Authority:

• Define avionics integration schemes that combine COTS VPX hardware with platform data buses (MIL-STD-1553, ARINC-429/664, Ethernet TSN) and mission computers.
• Develop interface-control documents (ICDs), signal-flow diagrams, and timing budgets; ensure alignment with OMS/UCI messages and cross-domain guard rules.

Airworthiness & Certification:

• Lead authoring of AF Form 1067s, E-series flight-clearance packages, and safety-of-flight analyses.
• Oversee creation and compliance of DO-254 (hardware) and DO-178C (software) artifacts when required.

Digital Thread / Model-Based Systems Engineering (MBSE):

• Capture avionics models in SysML/CAMEO and link to requirements, verification methods, and hardware trees.
• Drive configuration-control boards, incorporate red-line changes, and maintain synchronization of models and documents.

Lab-to-Flight Integration:

• Specify and validate wiring harnesses, signal conditioning, and power interfaces in integration system-in-the-loop (SIL) labs.
• Troubleshoot EMI/EMC, timing, and protocol issues; guide corrective actions through to flight-test readiness.

Flight-Test & Fielding Support:

• Draft test cards, telemetry requirements, and Interim Authorizations To Test (IATT).
• Serve as on-board or ground avionics lead during developmental and operational flights; analyze real-time data and coordinate anomaly resolution.

Mentorship & Stakeholder Engagement:

• Advise government leads, platform SPOs, and OEM avionics teams; present technical status to senior audiences.
• Mentor mid-level engineers and instill open-architecture and DevSecOps best practices in classified environments.

Required Skills and Qualifications:

• B.S. in Electrical, Avionics, Aerospace, or Computer Engineering (M.S. preferred).
• 20+ years of avionics design/integration experience on military fixed- or rotary-wing platforms, including hands-on flight-test and fielding.
• Active TS/SCI security clearance.
• Expert knowledge of MIL-STD-1553, ARINC-429/664, Ethernet (TSN/AFDX), VPX architectures, and timing/synchronization.
• Demonstrated success integrating Type-1 crypto, SATCOM/RF subsystems, and open mission systems (OMS/UCI, FACE, SOSA).
• Proven experience generating airworthiness artifacts and guiding systems through developmental and operational test.
• Proficiency with avionics E-CAD and MBSE tools (CAMEO/MagicDraw, Rhapsody, Altium/OrCAD).

Desired Skills:

• Experience with ABMS, CJADC2, or airborne C4ISR networking programs.
• Deep familiarity with DO-254/DO-178C compliance, RCC 324/125-15, and MIL-STD-461 EMI/EMC.
• INCOSE CSEP/ESEP, Designated Engineering Representative (DER), or USAF Test Pilot School academic credentials.
• Integrating software-defined radios, content routing, or SDN architectures into legacy aircraft environments.
• Agile/SAFe certification and exposure to DevSecOps pipelines (Platform One, Rancher).
