About the Role

Our client is an early-stage, founder-led company building AI-driven analytics for multi-sensor data, working across commercial, regulatory, and government/defence programs. Their platform has already been validated in real operational environments with early customers, and they're now extending it into new defence, security, and commercial applications.

They're hiring a Lead Engineer with applied ML depth. You'll work directly with the founder to build the company's technical capability from the ground up. This is a true foundational role with a lot of autonomy.

Your first project extends the platform into a new AI-driven decision-support system for a defence-sector client. It fuses multi-domain sensor data (radio-frequency, infrared, and visual-band), applies ML-based signal classification, and delivers a real-time visualization and decision-support interface. You'll be the primary technical builder across data ingestion, model development, dashboard, and system integration, working alongside a small set of specialist subcontractors (human factors, independent model review, security audit) who validate and stress-test what you build.

Past that first project, you'll help shape the company's engineering practices and pick up new work as the project portfolio grows.

What You'll Own

Data pipeline & fusion

• Stand up ingestion connectors for a range of sensor and data sources over common transport protocols (e.g. REST, gRPC, MQTT)
• Define a single unified schema and metadata model; identifiers, timestamps, frequency, location, calibration
• Align streams across time and space, and add automated quality checks that catch dropouts, outliers, and malformed records

Applied ML

• Build and train both supervised and unsupervised models for signal classification and anomaly detection
• Tune inference for near-real-time latency. This entarils; profiling, quantization, pruning, and similar techniques.
• Produce the evaluation evidence (accuracy, precision/recall, false-positive rates) needed to support independent third-party model review

Visualization & dashboard

• Build a live, GPU-accelerated dashboard that renders fused data with overlays and per-result confidence scoring.
• Design adaptive visual layers that stay responsive at near-real-time refresh under full data load.
• Fold in usability findings from an external human-factors reviewer.

Systems integration

• Bring the pipeline, models, and dashboard together into one modular, containerized system exposed through secure APIs.
• Support deployment and scenario-based testing inside client test environments.
• Partner with an external security auditor to close out findings ahead of deployment.

Requirements

What We're Looking For

• Strong full-stack engineering background. You are comfortable owning a system end to end.
• Applied ML experience: building, training, and deploying models in production or near-production settings, not just research or prototyping.
• Experience with real-time or near-real-time data pipelines and systems integration.
• Cloud infrastructure experience (AWS preferred, reflecting the current stack) and containerized deployment.
• Comfortable operating as the sole technical owner, with subcontractor partners handling independent review and validation rather than a peer engineering team.
• Bonus: signal processing, RF/sensor data, or defence/regulatory technical environments.
• Huger bonus: Dual citizenship (Canada & USA).
