Senior Software Developer – Artificial Intelligence​/Machine Learning Specialist

Overview

Chaac Technologies is seeking a Senior Artificial Intelligence / Machine Learning Developer to design, train, optimize, and deploy production-grade AI systems, with a strong focus on computer vision, edge inference, and mission-critical deployments.

This role is defense-first, but not defense-only. You will work on real-world AI systems used in defense, public safety, transportation, and high-risk industrial environments, where robustness, performance, and reliability matter more than demos.

You will collaborate closely with our CTO and R&D teams to take AI models from data to deployment, including training pipelines, optimization, and operational rollout on servers and edge devices.

• Design, train, and optimize machine learning and deep learning models, primarily for computer vision
• Work with modern neural network architectures, including transfer learning, data augmentation, and hyperparameter tuning
• Configure and manage training pipelines (batch size, learning rate, epochs, anchors, image resolution)
• Monitor and interpret metrics; apply early stopping, checkpointing, and resume training
• Prepare and manage large datasets, including annotation workflows (e.g. Label Studio)
• Evaluate models using standard metrics (confusion matrix, F1-score, IoU)
• Deploy models using Docker and Kubernetes, including conversion to ONNX
• Support inference pipelines on edge and resource-constrained devices
• Document training processes and collaborate with engineering and product teams

• Expert-level Python
• Py Torch
• Ultralytics YOLO
• Familiarity with ONNX
• GPU training and optimization
• Docker & Kubernetes
• Git, Bash scripting
• Experience managing large datasets
• Degree in Computer Science, AI/ML, or equivalent professional experience
• 5+ years of hands-on experience in ML / AI engineering
• Proven experience deploying ML models into production environments

• Custom model architectures
• Basic Elixir knowledge
• Model compression, pruning, or quantization
• Multi-modal AI (vision + thermal + acoustic)
• Synthetic data or photogrammetry
• MLOps pipelines and lifecycle management

• You’ve trained models that failed, debugged them, retrained them, and shipped them anyway
• You’ve worked with real datasets, not just clean academic benchmarks
• You’re comfortable owning the full ML lifecycle: data → training → evaluation → deployment
• You care about performance, robustness, and reproducibility, not just accuracy scores
• You maintain and update current backend deployments
• You enjoy working close to hardware, constraints, and real operational requirements

• You only want to do research without production responsibility
• Your experience is limited to notebooks and proof-of-concept demos
• You avoid deployment, monitoring, or operational constraints
• You’re looking for a junior or heavily guided role

• Competitive compensation and flexible work structure
• Opportunity to work on cutting-edge national security and defense AI initiatives
• A Senior-level position with architectural and scientific influence
• Collaboration with an elite, multidisciplinary team across AI, defense tech, and R&D
• Basic annual vacation of three weeks
• Six days of sick leave or personal days per year, non-cumulative
• One extra day off for your birthday
• Monthly public transit pass reimbursement (based on Montreal rates)
• Up to $500/year reimbursement for gym, sports, or other physical activities
• Flexible 40-hour week, remote or Old Montreal office, with occasional travel
• Group insurance and health benefits
