Staff Software Engineer - AI Marketing - CANADA

Keystone AI is building the AI growth platform for real estate. Backed by Bessemer Venture Partners and other top investors, we're a Series C company that has hit $100M in annual recurring revenue. More than 90,000 real estate professionals, including over 30% of the WSJ Real Trends top 100 agents in the United States, use us to run and grow their business. The Opportunity We don't just use AI. We build with it, ship with it, and think with it. We're in the top 1% of companies applying AI effectively, not just to our products, but to how we build them. With an unlimited budget for Anthropic tokens, our engineers use AI agents to write, review, and ship production code every day. We're building toward a world where humans design systems and AI builds them, and we're already further along that path than almost anyone else. As a Staff Software Engineer , you'll be a technical leader at the center of this transformation. You'll shape platform architecture, drive AI-powered product delivery, and raise the bar for what a small, AI-augmented engineering team can accomplish. This is a role for someone who already lives in their terminal with AI, who has strong opinions about how AI changes system design, and who wants to help define what a next-generation engineering organization looks like. What You'll Do Here are examples of the kinds of initiatives you'd work on today: Self-serve advertising platform. Build the systems that let agents purchase, launch, and manage Meta and Google ad campaigns directly within Presence, including automated campaign creation, flexible budgeting, and real-time performance reporting without ever touching a third-party ads dashboard. AI-generated social video. Build the pipeline that uses AI to create compelling, on-brand video content for agents and automatically publishes it to platforms like Instagram and TikTok, turning listing data and agent profiles into scroll-stopping social media at scale. Full-funnel attribution from ad dollar to closed deal. Design the data model and event architecture that connects a Google ad click to an AI conversation to a deal stage change, giving agents ROI visibility they can't get anywhere else and enabling the next evolution of CRM-driven campaigns. Next-level SEO and GEO for real estate agents. Build the systems that unlock the next layer of organic growth for our clients, helping them capture demand across traditional search engines and AI-powered generative search experiences alike. What We're Looking For Attributes You already build with AI daily.

You connect technical decisions to customer outcomes and long-term business value You communicate clearly and directly. You can explain complex tradeoffs to product, design, and executive stakeholders You're energized by ambiguity and speed.
