This is not your typical engineering internship. During your internship, you'll have opportunities for ownership that will significantly build your confidence as a software engineer. At one of the fastest-growing startups in technology, you'll ship code as early as your first week! You'll receive dedicated 1 : 1 mentorship, along with challenging technical assignments, novel product feature work, and many opportunities to stretch your technical skills, unlike ever before. We're building both a product and a technology, but doing whatever it takes isn't always straightforward. This role will help show you how to build the correct systems for scale, while also building something that customers want.

What you'll learn

• Build and ship : You'll design foundational aspects of the identity platform
• Partner with customers : Work directly with customers to understand their pain points and build product features for them. You're in the driver's seat to get your project in front of real customers
• See (and ship) scale : Handle both first-time and long-time customers running a CSV data test at Super Bowl Sunday scale
• Cross-team collaboration : Discuss the unique aspects of your projects with teams such as product, design, post-sales, and sales
• Continuous learning : Work with your mentor and a close-knit team to ensure your learnings from past projects are brought into future projects, helping you grow quickly as an engineer

What you'll bring to Persona
