Job description

About Us

At telli, we’re building the first AI‑native phone system. Since launching last year at Y Combinator (the same investors behind Airbnb, Stripe, Twitch, Coinbase, and others), we’ve grown >$2M in annualized revenue with a team of only 12 people.

Today, many companies fail in their customer communication not because they don’t care, but because they can’t keep up. The sheer volume of calls forces them to rely on low‑quality outsourced call centers or have their internal teams waste hours on repetitive calls.

With telli, our customers now rely on AI voice agents that handle their repetitive calls, freeing humans to focus on what matters—talking to customers when it counts. The result: higher efficiency, happier teams, and better customer experiences.

Legacy phone systems weren’t designed for an AI‑first world. That is why we are building the first AI‑native phone system that lets companies manage both their human and AI teams on one platform.

Our founding team knows this problem inside‑out. We ran a 150‑person internal call center at Enpal. We know how difficult and expensive it is to scale high‑quality customer experience with phone calls.

The opportunity is massive!!! and we’re just getting started. We’re on a mission to let every company provide a world‑class customer experience by ending the era of low‑quality call centers.

About The Role

This is the perfect role for someone early in their career (e.g. recent grad) who wants to get deep exposure to how startups operate, work directly with customers, and help scale AI products in the real world.

As an AI Operations Intern, you’ll work closely with the founders across both onboarding/agent development and customer success, supporting our team in making customers successful with telli.

You’ll help onboard new customers, develop AI agents, support existing accounts, and build the processes that help us scale.

What You’ll Do

Customer Ownership & Operations

• Support pilot accounts and help customers get live with AI agents
• Assist with customer communications, answer questions, and resolve basic issues
• Help track agent performance and customer health metrics
• Support customer workshops and training sessions

Agent Development

• Help build and refine AI agents alongside the team
• Support workflow creation for onboarding and pilot management
• Work with automation tools (n8n, Zapier) to improve internal efficiency
• Document best practices and playbooks

Cross‑Functional Collaboration

• Help translate customer feedback into insights for product and engineering teams
• Support operational tasks that help telli scale
• Prepare materials for customer and team meetings
• Jump in wherever needed to move projects forward

What Makes You a Great Fit

• You really enjoy working with customers and help them succeed
• You’re tech‑savvy (or have a semi‑technical background)
• You’re an excellent communicator in both English and German – especially writing
• You’ve experimented with AI agents or workflows and understand topics like prompt engineering
• You’re organized, hands‑on, and not afraid of unglamorous work
• You’re early in your career and hungry to learn fast

You may not make a good fit if…

• You have a pure business background but never worked with workflows or AI agents
• You only like 'strategic' work
• You want to work 9‑5 or remotely
