The Mission

The Small Airborne Effectors Division within the Kinetic Effects Business Area is a team of more than 200 professionals responsible for developing, testing, and producing small airborne missiles, UAS, and payload effectors for a diverse set of customers including the US Special Operations Forces, US Air Force, and US Army.

Position Overview

We are seeking an experienced, hands-on Systems Integration & Avionics Engineer to support a broad range of maintenance, integration, inspection, and troubleshooting activities for small airborne missiles, UAS, and payload effectors including avionics, instrument systems, and related airborne electronics. This role offers hands-on, varied work across avionics, integration, maintenance, mission support, and field operations in a prototype environment. Successful prototype programs often transition to production programs where the Systems Integration Engineer has a key role in developing production transition strategy, tooling setup, and assembly work instructions. Once production units are fielded, the Systems Integration Engineer also has opportunities for end-user technical support, sustainment, and training.

The ideal candidate will apply strong theoretical and practical knowledge to influence design and integration decisions based on experience to ensure mission-ready, safe, and compliant operations. This position is a core role within a multi-disciplinary rapid prototype design team.

In addition to technical, maintenance, and integration duties, the candidate may also be required to perform crew functions such as serving as a crew chief, conducting launcher maintenance and operations, and supporting prototype evaluations as mission needs evolve.

Key Responsibilities

• Design and integrate new solutions as part of multi-disciplinary prototype design team
• Integrate avionics, sensors, or control systems into UAS platforms; perform installation, wiring, mounting, alignment, configuration, documentation, and functional checks.
• Perform inspections, servicing, maintenance, and calibration of avionics/instrument systems (navigation, communications, flight-control electronics, sensors, data links, power systems, etc.).
• Troubleshoot and diagnose discrepancies, faults, and system anomalies using technical manuals, schematics, and test equipment.
• Perform system and Ground Support Equipment (GSE) maintenance, operation, setup, teardown, and inspection, ensuring safe and reliable launch capabilities.
• Conduct post-integration testing, system-level functional checks, and flight-line acceptance checks to validate system performance and airworthiness.
• Transition prototypes to production environments and support post fielding sustainment, technical support, and training.
• Maintain detailed maintenance, inspection, and repair records, track anomalies and repair history.
• Assist in or lead on-the-job training (OJT) for junior engineers, technicians or end-user personnel.
• Ensure compliance with applicable safety regulations, technical orders, standard operating procedures (SOPs), and record-keeping standards.
• Support mission readiness by responding to unscheduled maintenance or troubleshooting events, including field support or deployment travel if needed.

Basic Qualifications (Required)

• High school diploma or GED and 8 years of experience; Associate’s degree and 6 years, or Bachelor’s degree and 4 years of related experience. Higher degree in electrical engineering, avionics, aerospace technology, electronics, or related field preferred.
• Relevant experience in avionics/instrumentation maintenance, repair, and integration; ideally on uncrewed or crewed aircraft (e.g. 5+ years Group2/3 UAS experience or small missile systems).
• Demonstrated integration experience and proficiency with avionics/instrument systems: installation, troubleshooting, repair, calibration, documentation, and testing.
• Ability to read and interpret wiring diagrams, schematics, technical manuals, and installation drawings.
• Experience with UAS or missile launcher systems, including maintenance, operation, assembly, or troubleshooting.
• Proficiency with hand tools, power tools, electronic test equipment (multimeters, oscilloscopes, signal generators, etc.), and diagnostic instrumentation.
• Strong problem-solving skills, attention to detail, and ability to work independently or as part of a team.
• Must currently have a DOD Secret Clearance.
• Effective verbal and written communication skills.
• Willingness to travel and/or deploy as required for field support.
• Flexibility to work irregular schedules if mission or flight operations demand.

Preferred Qualifications

• Prior design, integration, and maintenance experience on uncrewed aircraft systems (Group 2/3) or small missile systems.
• Familiarity with datalink, sensor, navigation, or autopilot systems typical of UAS and airborne effector platforms, including ArduPilot and PX4.
• Electronic, avionics or instrument system certifications or equivalent (e.g., FAA A&P with avionics endorsement, manufacturer-specific avionics certification, or relevant training).
• Experience creating preliminary design schematics using Mechanical and Electrical CAD programs (Solidworks, Altium, Visio, DrawIO, etc.).
• Experience mentoring and training junior engineers, technicians, end-users.

Come break things (in a good way). Then build them smarter.

We're the tech company everyone calls when things get weird. We don’t wear capes (they’re a safety hazard), but we do solve high-stakes problems with code, caffeine, and a healthy disregard for “how it’s always been done.”
