Frontend Engineer

Coval is a platform for simulating and evaluating voice and chat agents. We've raised a $3.3M seed round, 10x'd our revenue in just 2 months and have strong customer demand for automated agent testing. To accelerate our growth, we're looking for a Senior Frontend Engineer to join our team and shape our core product experience.

No one's sure what an agentic future will look like. But we're certain AI agents are here to stay. And Coval will be the infrastructure that powers that.

Today, anyone can build and deploy an AI agent. While the first wave of AI agents is already delighting customers, creating reliable agents is becoming a growing challenge for companies.

At Coval, we're shaping the future of an agent-driven world. We know first-hand how AI agents operate and where they fall short. As AI adoption accelerates, one thing is clear: testing and reliability are more critical than ever.

Coval is the tool that empowers companies to not only create agents that delight and support customers but also deploy them with confidence, knowing they'll perform reliably in production. This is just the beginning of the AI-agent era. Evaluation infrastructure will massively shape it. There is no question if, it's who and when, and Coval aims to be THE agentic testing platform.

Coval is the first of its kind and we're just getting started. If you want to be part of this journey, join us!
