Senior Software Engineer, AI Products Remote - Canada

$150,000 - $200,000 CAD + equity

Your opportunity Our client is one of the fastest-growing software companies in Canada. They are a startup studio that builds and operates multiple agent-powered SaaS companies that automate distribution for businesses of all sizes. Their internal expertise in distribution has informed their R&D; and resulted in rapid revenue growth, with the portfolio companies on average scaling to a $1M annualized run rate within three months (and the most recent launch taking half that time). They have welcomed select strategic investors to their cap table and advisory ranks, but they have been profitable since inception and fund new projects with revenue.

Their portfolio offers businesses the capabilities of entire go-to-market teams through web applications that lean heavily on emerging technologies in natural language processing and generative AI. These products handle customer engagement and outreach, automate web and social platform activities, run A/B tests, and integrate with a range of customer systems and third-party platforms. Think of the portfolio as entire growth-hacking teams distilled into turnkey web applications.

As a senior software engineer, you’ll be stepping into a small, agile team in its scale-up phase. The engineering team is currently ~12 members strong and is led by the organization’s CTO. The team allocates cycles to the projects with the largest market opportunity, and engineers move between projects in response to demand, as they share an underlying tech stack. Hiring is underway to accelerate the development of a highly anticipated visual content generation product with a full order book.
