We are seeking an Aerospace Systems Engineer who will lead the design, integration, verification, and support of single board computer (SBC) and ATE solutions for safety‑critical aerospace and defense applications in rugged environments. This role requires hands‑on systems engineering across electronics, mechanical packaging, cable/harness design, software coordination, and qualification testing to ensure reliable operation under extreme environmental and mission conditions. The Systems Engineer will lead the development, integration, verification, and sustainment of automated test equipment (ATE) used for aerospace development and production environments.

This role requires in‑person support.

• Own system‑level requirements for SBC‑based avionics or embedded computing platforms and Automated Test Systems.
• Translate customer, program, and certification needs into technical specifications, interface control documents, and verification plans.
• Lead architecture definition for ruggedized compute modules, including processor boards, power interfaces, memory, I/O, thermal management, and enclosure integration.
• Coordinate cross‑functional design efforts across electronics, mechanical, firmware/software, cable/harness, and manufacturing teams.
• Define system‑level requirements for automated test equipment, test stations, fixtures, and support hardware.
• Lead design and integration of test solutions for electronic assemblies, electro‑mechanical subassemblies, cables, harnesses, and complete systems.
• Evaluate and select test equipment, instruments, connectors, fixturing, and environmental interfaces.
• Support hardware/software integration for test systems, including instrumentation, data acquisition, control logic, and automated test scripts.
• Support trade studies for component selection, form factor, power budget, thermal performance, obsolescence, cost, and manufacturability.
• Support failure analysis, root cause investigations, and corrective action implementation.
• Plan and execute verification and validation activities, including analysis, inspection, test, and demonstration.
• Support qualification testing for vibration, shock, thermal cycling, humidity, EMI/EMC, altitude, and other aerospace environmental conditions.
• Participate in design reviews, configuration control boards, and program technical reviews.
• Work with software teams to define boot, operating system, driver, middleware, diagnostics, and cybersecurity requirements.
• Ensure traceability from requirements through implementation, test, and acceptance.
• Support supplier management, hardware procurement, and production readiness for rugged SBC assemblies.

• Bachelor’s degree in Systems Engineering, Electrical Engineering, Computer Engineering, Aerospace Engineering, or related technical field.

• 5+ years of experience in aerospace, defense, or other safety‑critical embedded systems development.
• Experience with safety‑critical standards and aerospace qualification practices.
• Ability to read schematics, interface drawings, mechanical layouts, and test reports.
• Knowledge of configuration management, requirements management, and verification traceability.

• Experience with automated test software development using Python, C++, LabVIEW, Test Stand, or similar tools.
• Familiarity with SCPI, VISA,…
