What you will be working on
Collaborate closely with our customers and help them solve their problems to make their work more enjoyable
Build scalable backend infrastructure to handle thousands of phone calls per day
Build intuitive user experiences in an AI-first world
Optimize our voice agents for reliability, accuracy, and indistinguishability from talking to a real human
Stay ahead of emerging trends in voice AI, LLM agents, and distributed systems
✅ You might be a fit if you:
Are currently studying Computer Science, AI, or related fields, or recently graduated
Have done projects as a full-stack software engineer (preferably React, Typescript, Python)
Passion for building with LLMs - experience with agents and voice AI is a big plus
You leverage AI tools that make you more productive (Claude Code, Cursor, Windsurf, etc.)
You love challenging work and solving hard problems where others give up
You thrive in talking to customers, visiting them, and putting their needs first.
Want full ownership from day one and aren’t afraid to push hard.
❌ You might not be a fit if you:
Need clear structures and processes handed to you. (You’ll be the one building them.)
You don’t like to own features end-to-end.
Are looking for a cushy, slow-moving role.
You want to work 9-5 and prefer a remote environment
💥 Why join Hey Telo?
You’ll work side-by-side with the founders
You’ll ship real features used by customers — not just internal projects
You’ll get exposure to cutting-edge AI tools and frameworks
You’ll gain a deep understanding of how AI (and voice AI) can transform traditional industries
And if things go well, there’s a chance for a full-time role after the internship
