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 (75017), France – Hybrid
  • Reports to: Head of Data
  • Contract: Full Time
  • Start: ASAP
  • Experience: 2+ years (Junior / Mid)

Role & Mission

As a Machine Learning Engineer (Computer Vision), you will be responsible for the training, optimization, deployment, and monitoring of deep learning models across our ISR & Counter-UAS product line.

You will work on the full ML lifecycle, from dataset curation to running optimized inference models on edge compute units (Jetson & RPI) or cloud based GPU.

This role is hands-on, technical, and impactful: your work will directly influence field performance.

You will:

  • Improve and maintain training pipelines for detection, segmentation, and tracking models.
  • Define and automate evaluation frameworks.
  • Drive dataset governance: versioning, triage, augmentation, synthetic data, annotation workflows.
  • Optimize models for edge inference (weights conversion, quantization, pruning).
  • Contribute to deployment workflows and system integration with embedded & onboard compute.
  • Implement monitoring & feedback loops to ensure reliability in real operational conditions.
  • Work closely with Software, Hardware, and Field Ops teams to iterate quickly from lab → field → deployment

Candidate profile

You have already shipped computer vision models into real usage and you know how to own an ML pipeline end-to-end.

  • 2+ years of experience as ML Engineer / Computer Vision Engineer.
  • Strong skills in Python and deep learning frameworks (PyTorch preferred).
  • Hands-on experience training and evaluating models on large-scale image/video datasets (detection, segmentation, multi-object tracking).
  • Proven usage of experiment tracking and dataset/version governance (ClearML / MLflow / W&B + DVC or equivalent).
  • Operates comfortably with MLOps fundamentals: Docker, Git best practices, reproducible pipelines, CI/CD.
  • Able to take ownership, propose improvements, write clear documentation, and deliver production-level code, not research-only prototypes.

Nice to Have

  • Deployment experience on edge computing hardware (Jetson / RPI), including TensorRT / ONNX Runtime / quantization workflows.
  • Understanding of real-time performance constraints (latency budgets, throughput optimization, memory constraints, thermal/power envelopes).
  • Experience working in or alongside robotics, defense systems, aerospace, or dual-use applications, where reliability > benchmark scores.
