Cekura is a Y Combinator–backed startup redefining AI voice agent reliability. Founded by IIT Bombay alumni with research credentials from ETH Zurich and proven success in high-stakes trading, our team built Cekura to solve the cumbersome, error-prone nature of manual voice agent testing.

We automate the testing and observability of AI voice agents by simulating thousands of realistic, real-world conversational scenarios—from ordering food and booking appointments to conducting interviews. Our platform leverages custom and AI-generated datasets, detailed workflows, and dynamic persona simulations to uncover edge cases and deliver actionable insights. Real-time monitoring, comprehensive logs, and instant alerting ensure that every call is optimized and production-ready.

In a market rapidly expanding with thousands of voice agents, Cekura stands out by guaranteeing dependable performance, reducing time-to-market, and minimizing costly production errors. We empower teams to demonstrate reliability before deployment, making it easier to build trust with clients and users.

We’re building Scale AI for conversational agents at Cekura (YC F24). This summer, we’re looking for someone curious, scrappy, and obsessed with solving hard problems to join us as an AI Engineer Intern.

This isn’t the kind of internship where you polish slides or watch from the sidelines. You’ll be in the trenches with us — building, breaking, fixing, and shipping tools that test and monitor conversational AI agents used in production by real companies.

What you’ll do

• Build AI-driven tools that help companies test and benchmark their conversational agents.
• Hack together pipelines and evaluation methods for LLMs and voice/chat AI.
• Run experiments to make agents faster, smarter, and more reliable.
• Help design real-time monitoring systems that catch failures before users do.
• Talk to customers, learn what’s painful, and turn that into product improvements.

What we’re looking for

• You can code in Python and aren’t afraid of debugging hairy AI problems.
• You’ve built something with AI before (projects, research, side hustles, open-source).
• You like moving fast, experimenting, and learning by shipping.
• Startup chaos excites you more than big tech bureaucracy.

Bonus points if

• You’ve tinkered with conversational AI, evaluation frameworks, or monitoring tools.
• You’ve done a research project, hackathon, or internship in AI/ML.
• You want to work closely with founders and own a real slice of the product.

Why this internship rocks

• Work on cutting-edge AI problems that actually ship to production.
• Tiny team = everything you do matters.
• Learn startup life up close (chaotic, fast, fun, high-impact).
• Paid internship with potential for a return offer.
• You’ll leave with real systems you can point to and say, “I built that.”

Our platform is powered by Django on the backend for robust, secure server-side operations, and React on the frontend for a dynamic, modular user experience. We deploy on AWS, ensuring scalable and reliable cloud infrastructure, and use Redis with Celery for efficient queuing and background task management. On the AI side, we integrate cutting-edge models like GPT, Claude, Gemini, and Deep Seek to deliver top-notch accuracy in voice agent evaluations.
