About The Role
Our client is a scaling start-up developing AI-enabled physical security solutions and is seeking a highly capable, hands-on generalist Staff or Principal Software Engineer to join their core technical team. In this role, you will be instrumental in developing and scaling AI-powered video surveillance detection pipeline, leveraging state-of-the-art computer vision models to achieve sub-one-second detection latency at scale.
This is an individual contributor role focused on execution, architecture, and problem-solving rather than management. You will thrive if you enjoy working full-stack across complex systems, navigating ambiguity, pivoting quickly, and building high-impact products with low organizational overhead.
Key Responsibilities

- Integrate, test, and evaluate open-source AI/Vision-Language Models for real-time video surveillance and detection workflows.
- Solve performance bottlenecks to achieve sub-one-second latency at scale while maintaining low false-positive rates.
- Maintain hands-on involvement across the entire stack, leveraging AI-assisted workflows such as Claude Code to accelerate development.
- Participate in peer reviews, architecture discussions, and calibration of detection models.
Qualifications & Skills
- Seniority: Staff or Principal Software Engineer background with a strong track record of hands-on delivery.
- Core Tech Stack: Deep proficiency in Python, PostgreSQL, and Linux environments.
- AI/ML Experience: Hands-on experience or strong working knowledge in AI model evaluation, testing, and integration (experience with open-source vision/language models is a strong plus).
- Full-Stack/Generalist Mindset: Broad technical range with comfort moving across back-end architecture, data pipelines, and infrastructure integration.
- Adaptability: Thrives in fast-paced environments with rapid iteration, evolving scope, and minimal structure.
- Geographic Location: Remote within Canada. Ideally located within the Eastern Time Zone ± 1 hour
Key Mindset & Culture Fit
- Problem Solving: Superior technical problem-solving and architectural judgement.
- Collaboration: Humble, collaborative disposition with a keen appetite to work creatively both independently and in cooperation with an experienced leadership team. We value curiosity, innovation, high technical execution paired with respect and mutual trust.
