Avionics Electronics Engineer

About Alta Ares

Alta Ares is an air defense Neoprime. We build AI-guided interceptors to counter drones and cruise missiles, along with the software platform that powers them.

Our customers are NATO-aligned militaries and defense institutions, and our systems are regularly deployed during live exercises and operational demonstrations across Europe, the Middle East, and Asia.

Founded in 2024, we have grown to 90 people, raised over $60M, and increased revenue 40× this year. We are now entering a new phase of international expansion, industrial scaling, fundraising, and product development.

Role & Mission

Avionics Architecture & Hardware Design

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, with a strong focus on size, weight, power, and cost

Define the electrical architecture, power distribution, and harnessing for compact, high-dynamic airframes

Select and integrate flight controllers, navigation sensors (IMU, GNSS, magnetometer, air data), data links, and onboard compute

Design for manufacturability and reliability, from early prototypes through to series production

Integration, Test & Validation

Lead bench, hardware-in-the-loop, and environmental testing of avionics subsystems

Integrate electronics into the airframe and support full system integration with the software and guidance teams

Diagnose and resolve hardware, power, signal integrity, and EMI/EMC issues

Support ground and flight test campaigns, analyse test data, and feed results back into rapid design iterations

Suppliers & Industrialisation

Work with component suppliers to secure quality, cost, and lead times

Manage component obsolescence, second-sourcing, and supply chain resilience for critical parts

Produce and maintain design documentation, BOMs, interface control documents, and test procedures

Support qualification activities against relevant aerospace and military standards

Cross-functional Collaboration

Work closely with Software, Guidance & Navigation, Mechanical, Product and Flight Test teams in short iteration loops

Contribute to design reviews, trade studies, and product roadmap decisions

Support field deployments and live demonstrations with customers when required

Requirements

Candidate 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

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

Skills & Qualities

Hands-on, lab-oriented mindset: at ease with an oscilloscope, a soldering iron, and a test bench

Rigorous, structured problem solver able to deliver under tight timelines

Able to make pragmatic trade-offs between performance, cost, and schedule

Clear technical communicator in documentation and design reviews

High integrity, discretion, and understanding of security culture

Fluent English; French is a plus

Nice to Have

Experience in a defense startup, neoprime, or fast-moving hardware environment

Knowledge of MIL-STD-461, MIL-STD-810, DO-160, or equivalent standards

Embedded firmware experience (C/C++) on STM32 or similar microcontrollers

Experience integrating edge compute modules (e.g., NVIDIA Jetson) and high-bandwidth data links

Exposure to counter-UAS or air defense systems

Willingness to travel to test ranges and field sites
