Senior Full Stack Engineer, Growth

About The Opportunity 

Calendly is one of the most loved scheduling platforms in the world — and our opportunity for product-led growth is still massive. As a senior full stack engineer on our Growth team, you'll work on high-impact experiments that drive acquisition, activation, retention, and monetization for millions of users.

This is not a typical feature development role. You'll ship measurable experiments across the stack, build rapid MVPs, dig into data, and help shape our growth strategy alongside product and analytics partners.

We're looking for nimble, product-minded engineers who thrive on iteration, understand compounding impact, and want to learn fast.

And we’re looking for:

• A highly technical, talented, and humble human with a deep ownership mindset – you embody the “I’m not done, until we are done” spirit
• A team member who focuses on impact; a blend of high execution speed and sound judgement on how to pursue opportunities
• A collaborative team member who models technical leadership and is committed to elevating their team
• A team member who is not only open to diverse perspectives and approaches, but someone who actively seeks them out

What You’ll Do

You will report to one of our Senior Engineering Managers in our Growth organization, and your responsibilities will include:

• Ship full-stack experiments end-to-end: ideation, implementation, measurement, and iteration
• Improve key growth metrics across acquisition, conversion, engagement, and monetization
• Collaborate with cross-functional partners in product, design, analytics, and marketing
• Help scale our experimentation platform and growth infrastructure
• Make engineering tradeoffs that balance speed, quality, and long-term value
