Senior developer who builds and scales the AI agents powering Knak's email and landing page creation platform — owning the agent harness (orchestration, tool calling, context management), LLM evaluation pipelines, Python/Node.js microservices, Laravel APIs, and AWS infrastructure. Remote within Canada.
Why? Because our time is limited, our competition is fierce, and our margin for error is small. To have the biggest impact on the world, we stay focused on our core mission, which is...
Empowering marketers to be creative.
That’s why Knak exists.
In a world where AI has made everyone a creator, Knak helps marketers turn ideas into on-brand, high-performing campaigns at scale. The world's most AI-forward companies, including Meta, OpenAI, NVIDIA, Vercel, Notion and Stripe, use Knak as their agentic marketing production layer.
Here's what they and our investor Insight Partners figured out: creation got easy, but that’s making production harder. Every new idea and brief still has to be built, versioned, checked, approved, and shipped across every channel, and that work runs on handoffs, review cycles, and a lot of copy-paste. That middle stretch of the marketing stack has no system, no standard, and no owner.
Knak is the flexible factory for that work. Our customers set the brand rules, choose the tools that feed in and the platforms that send, and decide where AI does the work and where people do. We handle the repeatable parts, so marketers get their time back for the parts that aren't.
We're built by marketers, for marketers. We started with email because it's the hardest channel to get right and where many campaigns win or lose. Now we're bringing that same production discipline to every channel our customers use.
We’re looking for an experienced software developer to build and scale the AI agents behind Knak’s platform. In this role you'll develop the agent harness itself: the orchestration, tool calling, context management, and guardrails that let agents analyze data, generate complex marketing assets, and deliver real value to our customers. You'll also ensure we know they work, by building the evaluation suites that measure agent quality and catch regressions before they reach customers.
Base Salary: The anticipated base salary range for this position is $135,000 - 170,000k/year. Final compensation will be determined based on factors including relevant experience, skills, qualifications, and internal equity.

At Knak we have four foundational pillars. Culture, customers, product and growth.

We do this with a laser focus on hiring the right people who are smart, positive and who want more than the typical nine-to-five offers.

We show our investment in our people through our competitive salaries, equity in the company, great benefits, paid vacation, Life leave days (because life happens), team lunches and off-sites, and most importantly our commitment to YOUR career growth.
