We’re building the Voice AI infrastructure layer for financial services. Banks and fintechs use Monumint agent to automate loan origination, account opening, servicing and customer engagement.

You’ll work on:

1. Driving down voice latency to human-conversation levels while scaling to thousands of concurrent calls

2. Deploying agents that run durable workflows across days or weeks, maintaining state across calls, tools, documents, and human handoffs

3. Making AI agents reliable and observable in a financial workflows: tool calling, evals, guardrails, and deterministic fallbacks

We’re early, you’ll have a huge impact. Email me (my name at the URL) or apply here: https://www.workatastartup.com/companies/monumint
