Calendly Jobs (NOW HIRING)

This role focuses on building and running high-impact experiments that improve how users discover, adopt, and pay for Calendly within our Growth organization. You'll work across the stack, partner closely with product and analysts, and ship changes that are measured in real business outcomes.

This is not a traditional feature team role. The work is fast-moving, iterative, and data-driven. You'll regularly balance speed, quality, and long-term maintainability while operating in an environment with incomplete information.

• Ownership and follow-through; You care about results and learning, not just delivery
• Sound judgment paired with a bias toward action
• Technical leadership that raises the bar for the team
• Curiosity, humility, and openness to diverse perspectives

• Design, build, and ship full-stack growth experiments end-to-end
• Improve key metrics across acquisition, activation, engagement, and monetization
• Collaborate daily with product managers, designers, and analysts
• Analyze experiment results and iterate quickly based on data
• Contribute to our experimentation platform and growth infrastructure
• Make thoughtful engineering tradeoffs in pursuit of impact

On a typical week, you might:

• Build and ship an experiment that impacts a core funnel step
• Partner with product, design, and analysts to refine a hypothesis or flow
• Review experiment results and decide what to iterate, keep, or remove
• Improve or extend internal tooling that supports experimentation
• Review code, mentor teammates, and participate in team ceremonies

• 5+ years of professional software experience, with much of that working on user growth (acquisition, activation, retention) or monetization
• Strong, hands-on full-stack engineering skills, with the ability to independently design, build, and ship production changes across frontend and backend systems
• Demonstrated experience running product experiments end-to-end
• A data-driven approach to problem solving
• The judgment to balance speed and quality in a growth environment
• Comfort operating in ambiguous problem spaces where the path forward is not fully defined and success is measured by outcomes, not effort
• A collaborative working style and the ability to partner deeply with product, design, and analytics to drive results
• A collaborative mindset and a willingness to give and receive feedback
• Authorized to work lawfully in the United States of America as Calendly does not engage in immigration sponsorship at this time.

• Arrive with clear points of view on what experiments to run, why they matter, and how to evaluate their impact
• Be able to quickly dive into data to uncover growth or monetization opportunities
• Demonstrate ownership beyond implementation, from hypothesis formulation through post-launch analysis and follow-ups
• Have experience scaling growth systems or experimentation platforms in a production environment

You don't need experience with everything below, but you should be excited to work across it:

• Backend: Ruby on Rails, Grape, PostgreSQL, Redis
• Frontend: React, TypeScript
• Infrastructure: Google Cloud Platform, Kubernetes, Argo Workflows
