## 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.
We started with voice. Our SMS and RCS agents began as clones of the voice product — and they’re growing fast. Messaging is becoming a major part of our platform, and it needs a dedicated owner
---
## The Role
You’ll be a full stack engineer working across our platform — and you’ll head the engineering effort on our SMS and RCS expansion.
This means:
* Leading the engineering effort to evolve our SMS and RCS agents from voice-agent clones into a messaging-native product — rich cards, suggested replies, media, session handling
* 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 messaging providers and carrier infrastructure — delivery, 10DLC, opt-in/opt-out
* Debugging real production issues when things break
You’ll own the messaging 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 (new grads welcome)
* 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
* Messaging or telephony systems (Twilio, Telnyx, Bandwidth, SMS compliance)
* LLM applications (prompting, agent frameworks, evals)
---
## What This Is Like
You won’t just be building CRUD endpoints.
You’ll be building systems that:
* Decide what to say next in a live conversation — hours or days after the last message
* Enforce business rules and compliance requirements (TCPA, carrier filtering, quiet hours)
* Handle messy, real-world edge cases
* Run thousands of concurrent conversations reliably
Your code will power real conversations with real customers — and unlike voice, every word is in writing.
Visa sponsorship is not available for this role.
