About Alta AresAlta 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 & MissionAvionics Architecture & Hardware DesignDesign, develop, and integrate avionics and electronic subsystems for high-performance unmanned aerial systemsOwn schematic capture, PCB layout reviews, and component selection for flight-critical electronics, with a strong focus on size, weight, power, and costDefine the electrical architecture, power distribution, and harnessing for compact, high-dynamic airframesSelect and integrate flight controllers, navigation sensors (IMU, GNSS, magnetometer, air data), data links, and onboard computeDesign for manufacturability and reliability, from early prototypes through to series productionIntegration, Test & ValidationLead bench, hardware-in-the-loop, and environmental testing of avionics subsystemsIntegrate electronics into the airframe and support full system integration with the software and guidance teamsDiagnose and resolve hardware, power, signal integrity, and EMI/EMC issuesSupport ground and flight test campaigns, analyse test data, and feed results back into rapid design iterationsSuppliers & IndustrialisationWork with component suppliers to secure quality, cost, and lead timesManage component obsolescence, second-sourcing, and supply chain resilience for critical partsProduce and maintain design documentation, BOMs, interface control documents, and test procedures Support qualification activities against relevant aerospace and military standardsCross-functional CollaborationWork closely with Software, Guidance & Navigation, Mechanical, Product and Flight Test teams in short iteration loopsContribute to design reviews, trade studies, and product roadmap decisionsSupport field deployments and live demonstrations with customers when requiredRequirementsCandidate profileMSc or equivalent in Electrical/Electronic Engineering, Aerospace Engineering, or a related field3-8 years of experience in avionics, embedded hardware, or electronics design, ideally on UAS, aircraft, missiles, or other airborne systemsHands-on experience taking boards from schematic to tested flight hardwareSolid understanding of power electronics, motor control, RF and data links, and sensor interfacesFamiliarity with autopilot ecosystems (PX4, ArduPilot, or proprietary) is a strong plusSkills & QualitiesHands-on, lab-oriented mindset: at ease with an oscilloscope, a soldering iron, and a test benchRigorous, structured problem solver able to deliver under tight timelinesAble to make pragmatic trade-offs between performance, cost, and scheduleClear technical communicator in documentation and design reviewsHigh integrity, discretion, and understanding of security cultureFluent English; French is a plusNice to HaveExperience in a defense startup, neoprime, or fast-moving hardware environmentKnowledge of MIL-STD-461, MIL-STD-810, DO-160, or equivalent standardsEmbedded firmware experience (C/C++) on STM32 or similar microcontrollersExperience integrating edge compute modules (e.g., NVIDIA Jetson) and high-bandwidth data linksExposure to counter-UAS or air defense systemsWillingness to travel to test ranges and field sitesFind Jobs in France on Arbeitnow
