About the Opportunity
During the 2026 summer internship, you'll help us turn customer conversations into a sales superpower — and use Claude as the connective tissue that ties it all together.
We're looking for two curious, driven university students — one with a Computer Science background and one from MIS or Business — to collaborate on building an AI-assisted workflow that accelerates our sales cycle. Together, you'll use Claude to integrate and orchestrate our existing AI tools: pulling insights from Clari Copilot call recordings, powering smarter demos, sharpening Proof of Value criteria, and generating closeout presentations backed by real customer data.
Right now, our sales team is sitting on a goldmine of customer insights with no repeatable way to act on them — demos are too generic, Proof of Value tracking is entirely manual, and our AI projects operate in silos. That's where you come in. You'll use Claude to glue these pieces together into a cohesive, intelligent workflow that drives faster deal cycles and fewer meetings.
What You'll Build
By the end of the summer, you'll have helped us measurably shorten the sales cycle and reduce the number of meetings required to close deals by delivering:
What You'll Learn
What we are looking for from a Computer Science Major
You're a great fit if you're pursuing a Bachelor's in Computer Science or a related technical field, on track to graduate Winter 2026 or Spring 2027, and excited to apply your engineering skills to a real AI integration challenge inside a fast-moving sales environment.
You'll work from home with the flexibility of a remote role, coming together with teammates and leaders once or twice a week at a Dallas WeWork location.
