Avionics Systems Engineer - Flight Electronics

Alta Ares; Toulouse; On-site; EUR 70,000 - 100,000; Full time

Job summary

Alta Ares seeks an avionics architect to design and integrate avionics subsystems for high-performance unmanned aerial systems. You will own schematic capture, PCB layout reviews, and component selection, focusing on size, weight, power, and cost. Lead testing and integration with software teams.

Familiarity with autopilot ecosystems and a hands-on, lab-oriented approach are essential. The role requires collaboration across software, guidance, mechanics, and flight test teams on tight schedules.

Qualifications

• MSc or equivalent in Electrical/Electronic Engineering, Aerospace Engineering, or related field.
• 3–8 years of experience in avionics, embedded hardware, or electronics design for airborne systems.
• Hands-on experience taking boards from schematic to tested flight hardware.
• Strong understanding of power electronics, motor control, RF and data links, and sensor interfaces.
• Familiarity with autopilot ecosystems (PX4, ArduPilot, or proprietary) is a strong plus.

Responsibilities

• Design, develop, and integrate avionics and electronic subsystems for high-performance unmanned aerial systems.
• Own schematic capture, PCB layout reviews, and component selection for flight-critical electronics.
• Define electrical architecture, power distribution, and harnessing for compact airframes.
• Select and integrate flight controllers, IMU, GNSS, magnetometer, data links, and onboard compute.
• Lead testing, hardware-in-the-loop, EMI/EMC, and environmental testing.
• Collaborate with Software, Guidance, Mechanical, Product, and Flight Test teams.
