Knak is a mission-driven company 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. The Role As an Intermediate Full Stack Developer at Knak, you’ll build and maintain the systems that turn Knak content into email and landing page HTML.

You’ll work closely with Engineering teammates, Product Managers, Designers, QA, and DevOps to deliver reliable, well-tested features that meet user and business goals. You’ll make implementation-level design decisions within your area, contribute to architectural discussions, and help improve the quality and maintainability of the systems you work on. Roles & Responsibilities Build intuitive, responsive builder interfaces using Vue 3 and TypeScript, collaborating with designers and product managers to deliver experiences that meet design and functional requirements.

Support platform-specific exports by contributing to the Laravel transformer pipeline and following established implementation and testing patterns.
