About Bolna
Bolna is Voice AI infrastructure built for India - and now for the world. We help businesses deploy intelligent voice agents that can call, converse, and convert in any language, at scale. From collections to customer support to sales, our agents handle millions of conversations so humans don’t have to.

We’re a YC F25 company, backed by General Catalyst, with 1,050+ paying customers and growing fast. Our team of ~40 is based in Bengaluru.

About the role
Bolna's agents run across a stack of ASR, LLM, TTS, and telephony providers, at volume, across dozens of clients - which means something is breaking somewhere almost every day. A call that failed. A prompt that didn't do what a client expected. A webhook that stopped firing. This role is the first line on that queue: for every ticket, you have to work out what actually broke, why, and whether you can fix it yourself.

You won't usually be able to look up the answer in a known-issues doc, because a lot of what breaks at Bolna hasn't broken in quite that way before. You're expected to reason from first principles:



pull the transcript, pull the logs, form a hypothesis, test it, fix what's yours to fix, and write a sharp handoff for what isn't. Nobody's handing you a script.
If you like puzzles more than tickets, this is a positive fit.

What you'll own
- Ticket triage and root-cause analysis. Work the daily queue of technical support issues. Diagnose the actual root cause using transcripts, call logs, and system metadata before assuming what's wrong.
- Prompt fixes. When an issue traces back to agent instructions, you write and test the fix yourself - not just describe the symptom to someone else.
- SQL-driven investigation. Pull your own data from BigQuery/Metabase to confirm or kill a hypothesis, instead of waiting on someone else's report.
- API and webhook debugging. Trace failed webhook deliveries, malformed payloads, and integration issues between client systems and Bolna's platform.
- Evidence-backed es
