About Alta Ares

Alta Ares is a deeptech startup founded in 2024, building real-time AI for defense operations (ISR, C-UAS). Our primary clients are NATO-aligned militaries, with regular deployments during live exercises. Raised €2M pre-seed in May 2025 Products include:

• Real-time AI ISR module deployable on drones and tactical platforms
• Counter-UAS solution enabling autonomous drone takeover under GNSS-denied environment
• Full-stack MLOps platform for training & deploying military-grade AI models
• Data fusion and trajectory prediction
  

Position details

• Location: Paris or Toulouse, France, with regular travel to testing sites, operational theaters, partner locations, and NATO countries
• Reports to: Head of Product Hardware / Engineering
• Position objective: Lead the integration of radar systems into Alta Ares’ counter-drone ecosystem, ensuring operationally effective detection and tracking capabilities across all platforms, and supporting field deployment and system optimization in operational theaters.
• Contract: Full-time, permanent position (CDI)
  

Role & Mission

As Radar Engineer, you will lead the integration of radar systems into Alta Ares' counter-drone ecosystem. You will work on integrating various radar technologies (ground-based, drone-mounted, mobile) with our Ground Control Station (GCS), C2 systems, and drone platforms to create comprehensive detection and tracking solutions for counter-UAS operations.

Radar Integration & Development

• Integrate diverse radar systems into Alta Ares' product ecosystem (GCS, C2, drone platforms)
• Evaluate and select radar technologies for different operational scenarios
• Interface radar data with AI/ML detection and tracking systems
• System Architecture & Integration
• Design integration architectures between radars, C2 systems, and GCS
• Ensure real-time data processing and low-latency target tracking
• Create standardized integration frameworks for multiple radar vendors
• Implement data fusion between radar and other sensors (RF, EO/IR, acoustic)
  

Performance Optimization

• Conduct radar performance testing and validation in various environments
• Optimize detection ranges, false alarm rates, and tracking accuracy
• Develop ECCM (Electronic Counter-Counter Measures) capabilities
• Analyze operational data to improve detection algorithms
• Adapt systems for challenging environments (urban, maritime, mountainous)
  

Field Testing & Deployment

• Support radar deployment and integration in operational theaters
• Conduct field testing and performance validation
• Troubleshoot integration issues in operational conditions
  

Cross-Functional Collaboration

• Work with hardware teams on radar mounting and platform integration

• Collaborate with software/AI teams on data processing and fusion
