Are you a builder?
Then Jobber might be the place for you! We're looking for a Senior Front-End Developer, Web Experimentation, to join our Web Strategy team.
Jobber exists to help people in small businesses be successful. We work with small home service businesses, like your local plumbers, painters, and landscapers, to transform the way service is delivered through technology. With Jobber they can quote, schedule, invoice, and collect payments from their customers while providing an easy and professional customer experience. Running a small business today isn’t like it used to be—the way we consume and deliver service is changing rapidly, technology is evolving, and customers expect more. That’s why we put the power and flexibility in their hands to run their businesses how, where, and when they want!
Our culture of transparency, inclusivity, collaboration, and innovation has been recognized by Great Place to Work, Canada’s Most Admired Corporate Cultures, and more. Jobber has also been named on the Globe and Mail’s Canada’s Top Growing Companies list, and Deloitte Canada’s Technology Fast 50™, Enterprise Fast 15, and Technology Fast 500™ lists. With an Executive team that has over thirty years of industry experience of leading the way, we’ve come a long way from our first customer in 2011—but we’ve just scratched the surface of what we want to accomplish for our customers.
The Role:
Jobber's website is one of our most important growth engines — the place where small home-service businesses first meet the product and decide to start a trial. The Web team builds and continuously improves , shipping new pages, running a high-velocity experimentation program, and pushing the limits of what a marketing site can do for conversion, SEO, and AI-driven discovery.
We're looking for a Senior Front-End Developer with deep web experimentation experience — to drive high-velocity A/B and multivariate testing across our web properties while elevating our technical architecture. You'll work across our modern Jamstack stack (Next.js, Sanity headless CMS, React, TypeScript) as well as our traditional headful WordPress platform (PHP, Twig templates), expanding our component libraries and engineering high-performance CRO frameworks. CMS familiarity is essential: you'll build and optimize features across both modern headless APIs and legacy PHP/Twig codebases. This is a senior individual-contributor role with real technical influence: you'll set experimentation standards, mentor developers, and partner with the Engineering Manager on quality and site performance.
Just as importantly, we want someone who treats AI-assisted development as a core engineering skill. We're actively reshaping how we build — using AI coding agents, MCP-connected tooling, and automated workflows to move faster without sacrificing quality — and we want this person to help lead that evolution, not just keep up with it.
