Lead Software Engineer / Hands-on – Founding Toronto Team

Toronto (Hybrid 4 days) | Full-Time | AI SaaS Startup

We’re helping an AI-native SaaS startup build its Toronto engineering hub, starting with a founding technical leader who’s eager to scale both systems and teams.

• Drive technical direction, architecture, and design across backend, frontend, and ML systems
• Stay hands-on—review code, lead design sessions, and contribute to builds
• Manage and mentor a growing team across backend, frontend, dev tools, and QA
• Collaborate closely with the VP of Software and HQ team in Silicon Valley
• Own delivery of key product features and infrastructure from the Toronto office
• Lead hiring, onboarding, and shape engineering culture in a new hub
• Help scale the team from 3 → 20+ engineers over the next 24 months

• 10+ years of software engineering experience
• 3+ years in a technical leadership or management role
• Built or scaled cloud-native SaaS platforms (AWS, GCP, or Azure)
• Deep expertise in backend systems, frontend architecture, or both
• Experience building or integrating AI / ML infrastructure or LLM-powered products
• Track record of leading cross-functional teams in high-growth or startup environments
• Mentoring early-career engineers and growing healthy engineering cultures
• Bonus: experience with developer tools, IDEs, or platforms for engineers

• Are you still hands-on but ready to grow and lead others?
• Do you thrive in startup environments where speed and ownership matter?
• Have you built scalable, production-grade systems in the cloud?
• Can you build trust across product, design, ML, and engineering teams?

If you answered “yes” to most of these, we’d love to hear from you. This is a unique opportunity to help build both a world-class engineering system and a world-class engineering team — from the ground up.
