Senior Front-End Developer, Web Experimentation in Winnipeg

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.

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.

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.

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 systems.
• 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 using AI coding tools and agents fluently.
• 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.
• Architect and execute complex A/B and multivariate experiments across high-converting marketing flows.
• Support SEO, LLM, and AI-search initiatives with the technical foundations that keep the site discoverable as search evolves.
• 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.
• Identify and act on opportunities to improve the stack, tooling, and processes, and maintain strong team documentation.

To be successful, you should have:

• 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.
• 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).
• Hands-on AI-assisted development.
• A growth and experimentation mindset.
• Technical leadership without ego.
• Strong communication.
• Ambitious and humble.
• Comfort in the grey areas.

Nice to have:

• Back-end familiarity.
• 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.

Compensation: At Jobber, we believe that compensation should be transparent, fair, and reflective of your experience and growth. This role has a minimum annual salary of $121,000, a midpoint of $142,200, and a maximum salary of $163,600 designed to show the progression from learning the ropes to truly excelling.

What you can expect from Jobber:

• A total compensation package that includes an extended health benefits package with fully paid premiums for both body and mind, matching in RRSP, TFSA or FHSA, and stock options.
• A dedicated Talent Development team and access to coaching, learning, and leadership programs to help you grow your career, reach your goals, and unlock your full potential.
• A unique opportunity to build, grow, and leave your impact on a $400-billion industry that has no dominant player…yet.
• To work with a group of people who are humble, supportive, and give a sh*t about our customers.
• We believe that diverse teams perform better and that fostering an inclusive work environment is a key part of growing a successful team.
