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:

• A Claude-powered integration layer that connects Clari Copilot, CRM data, and other AI tools into a single, repeatable sales workflow
• A prompt library and orchestration framework using Claude to extract demo-relevant insights from call transcripts and route them to the right stage of the sales cycle
• Standardized Proof of Value success criteria derived from actual customer conversations and automatically surfaced by Claude during active deals
• An AI-automated Proof of Value status update workflow fed by Clari Copilot outputs and synthesized by Claude for sales rep consumption
• A template-driven closeout deck auto-populated with real engagement data via Claude API integrations
• All project artifacts, prompts, templates, and documentation version-controlled in GitHub
• Handoff documentation enabling the sales team to self-sustain and extend the process post-internship

What You'll Learn

• How to use Claude as an AI orchestration layer to connect disparate tools and automate multi-step workflows
• How enterprise sales cycles work and where AI creates the most leverage
• Hands-on experience with prompt engineering, API integration, and agentic AI design patterns
• How to take an ambiguous problem, scope a solution, and ship something that sticks
• Strong mentorship from Sales, Marketing, and Engineering leaders

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.

What we're looking for:

Eligibility

• Programming experience: Hands-on experience with at least one language such as Python, JavaScript, C#, Java, or PHP
• API & integration skills: Familiarity with REST APIs, JSON, and connecting third-party services or data sources
• AI curiosity: Exposure to or strong interest in working with large language model APIs (such as Claude, OpenAI, or similar)
• Version control: Comfortable using Git and GitHub for code and documentation management
• Communication: Able to explain technical concepts clearly to non-technical audiences — in writing and in person
• Work style: Self-directed, detail-oriented, and comfortable managing multiple workstreams with minimal hand-holding
• AI mindset: Willing to explore, experiment with, and build using AI tools as a core part of your workflow

Nice to have
