You enjoy working across new technologies and you’re excited to work across the stack from back-end to front-end work
You love digging into performance and scalability issues to find breakthrough solutions: a slow-loading UI, too many clicks in a workflow, a database query timing out, a queue that won't drain. You believe every problem can be solved, and you'd rather run toward it than around it.
You enjoy shipping code early and often, working closely with products to build better software based on feedback from thousands of end users.
You embrace Klaviyo's "always learning" culture. We learn faster together, which is part of why this program happens in person.
You've already experimented with AI in work or personal projects, and you're excited to find ways to make your work smarter and more efficient.
