CX2 is a next-generation defense technology company founded to deliver spectrum dominance for the United States and our allies. CX2’s AI-enabled hardware and software platforms detect, disrupt and defend the electromagnetic spectrum across land, air, sea and space domains.

We are seeking an Avionics Systems Integration Engineer to own the integration, verification, and operational readiness of avionics systems for advanced unmanned aircraft and defense platforms. This is a hand-on role responsible for bringing together flight-critical hardware, mission systems, sensors, payloads, communications equipment, and software into fully operational aircraft ready for ground and flight testing. The engineer will own technical execution across development, integration, test, troubleshooting, and deployment while working closely with cross-functional engineering teams in a rapid, iterative development environment.

The ideal candidate is a hands-on engineer who thrives on building, testing, and solving difficult technical problems. They are comfortable working directly with avionics hardware, electrical systems, Linux-based computers, embedded devices, and networked systems, and can independently diagnose issues at the component, subsystem, and UAS levels. They take ownership of system performance, drive issues to resolution, continuously improve integration processes, and excel in environments where rapid iteration, accountability, and technical excellence are expected.

Integrate avionics hardware, mission systems, sensors, communications equipment, and flight control systems into unmanned aircraft platforms.

Perform system bring-up, troubleshooting, and validation of partial and complete avionics systems.

Support hardware-in-the-loop (HIL), ground, and flight test activities, including test execution, data collection, and root-cause analysis.

Diagnose and resolve hardware, software, networking, and system integration issues across complex aerospace platforms.

Configure and maintain Linux-based systems, mission computers, embedded devices, and network infrastructure.

Support aircraft electrical system integration, wiring verification, power distribution validation, and interface troubleshooting.

Develop and execute integration procedures, test plans, and verification activities.

Work closely with electrical, software, autonomy, and flight test engineers to identify and resolve system-level issues.

Utilize laboratory equipment including oscilloscopes, multimeters, power supplies, logic analyzers, network analyzers, and test fixtures.

Support field testing, aircraft deployment activities, and customer demonstrations as required.

Create technical documentation including integration procedures, test reports, and troubleshooting guides.

Bachelor's degree in Aerospace Engineering, Electrical Engineering, Systems Engineering, Computer Engineering, or related field.

5+ years of experience in avionics integration, aerospace systems engineering, flight test, or related disciplines.

Strong understanding of aircraft electrical systems, avionics architectures, and system integration practices.

Hands-on experience troubleshooting hardware, electrical, networking, and software issues in complex systems.

Proficiency using Linux from the command line for system configuration, diagnostics, log analysis, and networking tasks.

Experience with IP networking concepts, including Ethernet, TCP/IP, routing, switching, VLANs, firewalls, and network troubleshooting.

Experience with avionics communication protocols such as CAN, MAVLink, ARINC 429, RS-232/422/485, Ethernet, or MIL-STD-1553.

Ability to read electrical schematics, wiring diagrams, interface control documents, and system architecture drawings.

Experience operating laboratory test equipment and conducting structured integration testing.

Strong troubleshooting mindset with the ability to isolate issues across hardware, software, networking, and avionics domains.

Experience with unmanned aircraft systems (UAS), autonomous systems, defense programs, or military aviation.

Experience with PX4, ArduPilot, embedded Linux systems, or mission computer architectures.

Familiarity with EO/IR payloads, radios, datalinks, SATCOM, or tactical communications systems.

Experience supporting flight test operations and aircraft deployment activities.

Familiarity with MIL-STD-810, MIL-STD-461, DO-178C, DO-254, or related aerospace standards.

Active Secret security clearance or ability to obtain one.

To conform to U.S. Government export regulations, applicant must be a US Citizen, Green Card holder, or be eligible to obtain the required authorizations from the U.S. Department of State. Learn more about the ITAR here.

Competitive salary, stock options and benefits, including health, vision and dental.

401K enrollment at 90 days.

Generous PTO + most Federal Holidays observed.

Collaborative and inclusive work environment.

Access to the latest tools and technologies.

High levels of responsibility and autonomy.

Professional growth and development opportunities.

Access to the hardest problems in electronic warfare.

The ideal candidate is the engineer everyone calls when the aircraft isn't working. They can connect to a Linux box, inspect logs, troubleshoot network traffic, validate electrical interfaces, isolate failing hardware, and methodically work through integration issues until the system is operational. They are equally comfortable reviewing system architecture diagrams, working at a lab bench with test equipment, or supporting troubleshooting on an aircraft during flight test operations.
