Main function and scope:

We are looking for a Hardware Engineer with a good electronic background to design, validate, and qualify advanced electronic systems for aerospace and defense applications. The role covers the electronic board design, debugging, validation and qualification activities, including radiation testing campaigns. The successful candidate will be expected to understand hardware behaviour at component, board, and subsystem level, and investigate failures to improve design solutions.

Core functions:

• Design, develop, and maintain electronic boards and hardware subsystems for avionics equipment, and electronic systems.
• Perform component selection, schematic design, analysis and support PCB layout activities.
• Design hardware incorporating DC/DC converters, LDO regulators, analog, digital, and mixed-signal circuitry, including FPGA-, microcontroller-, ADC/DAC-, and communication interface-based systems.
• Develop test strategies, test plans, procedures and verification campaigns
• Develop, integrate, and maintain automated test systems using laboratory instrumentation such as oscilloscopes, power supplies, signal generators, and data acquisition systems.
• Perform hardware debugging, electrical characterization, and functional verification activities.
• Coordinate and execute radiation test campaigns (TID, SEE, SEL, SEU, SET, displacement damage) in collaboration with specialized external facilities.
• Execute environmental qualification testing, including thermal, vibration, EMC/EMI, and reliability testing.
• Analyze test results, perform root-cause investigations, and implement corrective or mitigation actions to improve design robustness and radiation tolerance.
• Prepare technical documentation, test reports, verification evidence, qualification reports, and customer deliverables.
• Collaborate closely with systems, hardware, firmware, software, quality, manufacturing, and project management teams.
