Senior Front-End Developer, Web Experimentation

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 getjobber.com, 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.

What you'll do:

Build on a modern front-end stack

• Engineer across a hybrid web stack — ship production features in Next.js, Sanity, and React with TypeScript, alongside ongoing support and enhancements for our headful WordPress (PHP/Twig) environment across getjobber.com.

• Contribute to and extend our shared component library and design system so the team builds faster on consistent, reusable, well-tested foundations.

• Own performance and accessibility as first-class requirements — Core Web Vitals, semantic and accessible markup, and fast, resilient page loads that directly support conversion.

• Work seamlessly between headless and traditional CMS architectures — integrate APIs and structured content in Sanity while maintaining Twig-templated components in WordPress as we transition our web ecosystem.

• Write well-tested, scalable, well-organized code and drive consistent engineering practices through code review.

• Collaborate with our other developers on best technical practices and project decisions.

Push our AI-assisted workflow forward

• Use AI coding tools and agents fluently (e.g. Claude, AI-assisted IDEs, agentic workflows) to accelerate development while keeping a critical eye on output quality and reliability.

• Improve how the team works with AI — building and refining MCP integrations, prompts, and context so our tickets, content, and codebase are AI-ready.

• Help define and benchmark team standards for AI-assisted development — identifying what works, documenting it, and raising the whole team's baseline.

Power experimentation and growth

• Architect and execute complex A/B and multivariate experiments across high-converting marketing flows, partnering with CRO leads and data analysts to design statistically sound, performant test variants.

• Build for experimentation velocity and statistical integrity — minimize flicker, ensure client/server-side rendering accuracy, and reduce time-to-market from test hypothesis to live variant.

• Support experimentation with the technical foundations (structured data, performance, rendering) that use best practices

Raise the technical bar

• Set patterns and technical direction for how we build, and bring the team along through pragmatic, well-reasoned decisions.

• Mentor and coach other front-end developers, lifting their skills and holding the team to its engineering principles.

• Partner with the Engineering Manager on technical standards, code quality, and architecture

• Identify and act on opportunities to improve the stack, tooling, and processes, and maintain strong team documentation.

To be successful, you should have:

• Deep front-end expertise. Expert command of HTML, CSS, JavaScript/TypeScript, accessibility, and web performance, plus several years building production applications.

• Proven web experimentation & CRO expertise. Hands-on experience architecting and shipping complex A/B, Multivariate Testing, and personalized web experiments with measurable conversion outcomes.

• Experience with web experimentation and feature flag platforms (e.g. Kameleoon, Optimizely, VWO, LaunchDarkly) and product analytics tools (e.g. Amplitude, GA4).

• Strong Jamstack and modern front-end stack. Mastery of Next.js, React, TypeScript, and modern rendering strategies with a focus on performance and accessibility.

• Experience working within a design system or maintaining a shared component library.

• Versatile CMS background (Headless Sanity & WordPress/Twig). Experience modeling content in headless CMS platforms (Sanity/Contentful) alongside hands-on proficiency in traditional WordPress, PHP, and Twig templates.

• Hands-on AI-assisted development. You actively use AI coding tools in your day-to-day work and have a point of view on where they help, where they don't, and how to use them responsibly.

• A growth and experimentation mindset. You're comfortable building for measurement and iteration, and you care about the business outcome your code drives.

• Technical leadership without ego. You set standards and mentor others while staying collaborative and open to better ideas.

• Strong communication. You collaborate easily with both technical and non-technical partners — designers, marketers, and CRO.

• Ambitious and humble. You don't accept the status quo simply because "it's what we've always done" — you push for better, newer, more innovative approaches while staying grounded.

• Comfort in the grey areas. You're adaptable, can prioritize amid ambiguity and changing priorities, and break large, complex problems into shippable pieces.

Nice to have:

• Back-end familiarity. Comfort working beyond the front end: integrating APIs and services, or background experience with full-stack development.

• Experience collaborating closely with designers in Figma.

Location:

We believe great collaboration is intentional, and sometimes that means coming together in person to build, brainstorm, and connect. To support this, the role is open to candidates based in one of our hub cities: Edmonton, Toronto, Vancouver, or Kitchener-Waterloo.
