Avionics Electronics Engineer

About Alta Ares

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
