Role Summary

At Zone 5 Technologies, Systems Integration & Test Engineers support the development and execution of Hardware-in-the-Loop (HITL) environments, as well as the integration, bring-up, and validation of new technologies and features.

This role is hands-on and execution-focused, operating within a collaborative cross-functional team to mature, integrate, test, and troubleshoot avionics, systems, and subsystems prior to production.

Mid-level engineers in this role independently develop & execute integration and HITL test environments, own subsystem-level integration efforts, and play a key role in validating hardware and software prior to testing. This position balances hands‑on engineering with increasing technical ownership and responsibility.

Responsibilities

• Develop and maintain MATLAB/Simulink models for system validation
• Support code generation and embedded integration
• Validate control logic and system performance
• Design wiring harnesses and signal routing architectures
• Validate communication protocols (CAN, Ethernet, UART)
• Perform signal integrity and timing analysis

Mechanical Integration (Mechanical)

• Support thermal management and environmental validation
• Develop integration hardware and mounting solutions
• Execute and lead integration test procedures
• Identify, troubleshoot, and resolve integration issues
• Support flight test campaigns and on‑aircraft validation

Qualifications

• Bachelor’s degree in relevant engineering field
• 3–8+ years of experience in aerospace integration/test
• Strong understanding of embedded systems and avionics architectures
• Experience working independently in lab/test environments

Preferred

• SIL / HIL experience

Leveling Signals

• Works independently on well‑defined problems
• Owns subsystems or test environments
• Contributes to system‑level decisions

Pay Range

• Level III - $129k - $149k
• Level IV - $150k - $170k
• Pay range for this role: $129,000 USD - $170,000 USD
