About AviaryAI

We build AI voice agents for banks, credit unions, and insurers.

Our agents are live and handling real customer calls today. We’re backed by Y Combinator and growing.

So far we’ve focused on outbound calls. Now we’re building inbound — AI that answers incoming customer service calls. This will become a major part of our platform.

The Role

You’ll be the primary engineer building our voice product.

This means:

• Writing the backend logic that manages conversation state and decision-making (Python)
• Building internal dashboards and tools to configure and debug agents (TypeScript)
• Contributing to our core frontend application as needed
• Integrating with banking APIs and telephony systems
• Debugging real production issues when things break

You’ll own this vertical from prototype to high-volume production.

This is not a ticket-driven role. You’ll have a lot of responsibility and a lot of autonomy.

What We’re Looking For

• 1–3 years full stack experience
• Strong in Python
• Comfortable in TypeScript / modern frontend frameworks
• Experience building systems with real state or multi-step workflows
• Comfortable integrating third-party APIs
• Able to work without detailed specs

Bonus if you’ve worked in:

• Startups
• Fintech / insurance
• Real-time systems (WebSockets, telephony, Twilio, etc.)

What This Is Like

You won’t just be building CRUD endpoints.

You’ll be building systems that:

• Decide what to do next in a live conversation
• Enforce business rules
• Handle messy, real-world edge cases
• Observe real time systems handling high volumes of concurrent streams

Your code will power real-time phone calls with real customers.
