Avionics Electronics Engineer

About the role

Alta Ares builds AI-guided interceptors to counter drones and cruise missiles, together with the software platform that powers them. Its customers are NATO-aligned militaries and defence institutions, and its systems are used in live exercises and demonstrations across Europe, the Middle East and Asia. Founded in 2024, the company has grown to 90 people and is now expanding internationally and scaling its industrial operations. This role covers avionics architecture and hardware design, integration, test and validation, supplier work and industrialisation.

Key responsibilities

• Design, develop and integrate avionics and electronic subsystems for high-performance unmanned aerial systems, with a focus on size, weight, power and cost
• Own schematic capture, PCB layout reviews and component selection for flight-critical electronics, and define electrical architecture, power distribution and harnessing
• Select and integrate flight controllers, navigation sensors (IMU, GNSS, magnetometer, air data), data links and onboard compute
• Design for manufacturability and reliability from prototype through to series production
• Lead bench, hardware-in-the-loop and environmental testing, and integrate electronics into the airframe with the software and guidance teams
• Diagnose hardware, power, signal integrity and EMI/EMC issues, and support ground and flight test campaigns
• Work with suppliers on quality, cost and lead times, manage obsolescence and second-sourcing, and maintain BOMs, interface control documents and test procedures
• Support qualification against aerospace and military standards and collaborate with Software, Guidance & Navigation, Mechanical, Product and Flight Test teams

Required profile

• MSc or equivalent in Electrical/Electronic Engineering, Aerospace Engineering or a related field
• 3-8 years of experience in avionics, embedded hardware or electronics design, ideally on UAS, aircraft, missiles or other airborne systems
• Hands-on experience taking boards from schematic to tested flight hardware
• Fluent English; French is a plus

Required skills

• Solid 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
• Nice to have: MIL-STD-461, MIL-STD-810, DO-160 knowledge, embedded firmware (C/C++) on STM32, edge compute modules (e.g. NVIDIA Jetson), counter-UAS or air defense experience, and willingness to travel to test ranges
