AI Solutions Engineer

About Bolna

Bolna is Voice AI infrastructure built for India. 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 ~25 is based in Bengaluru.

The Role

You're the person who makes our voice agents actually sound good and actually work for real customers. As an AI Solutions Engineer, you'll sit at the intersection of our product and our customers. Your primary job is to design, write, and iterate on the prompts and tools that power Bolna's voice agents, making them smarter, more natural, and more effective for each use case.

You'll work closely with customers to understand their goals, build agent flows, test conversations, and fix what breaks. No heavy coding required-if you can vibe-code a basic script or write a solid system prompt, you're qualified.

What You'll Do

Write, test, and iterate on system prompts for voice agents across industries like D2C, fintech, healthcare, and logistics

Listen to real call recordings, identify where agents fail, and fix them

Build conversation flows and call pathways for new customer deployments

Help onboard new customers-understand their use case, set up their agent, and get it live

Maintain a growing library of prompts, templates, and best practices across Bolna's verticals

Red-team agents-try to break them, find edge cases, and make them bulletproof

Work with vernacular inputs: test agents in Hindi, Hinglish, and regional languages

Feed insights back to product and engineering-you'll see what customers need before anyone else does

What We're Looking For

Must-have:

You've spent serious time prompting ChatGPT, Claude, or similar LLMs-not just casually, but to actually build or solve something

You're obsessive about language-you notice when a sentence sounds off, robotic, or unclear

You can think from the customer's perspective and the end-user's perspective at the same time

You're comfortable with ambiguity and can make decisions without a full playbook

Strong written and verbal communication in English. Hindi or any other Indian language is a big plus

Good to have:

You've tinkered with voice AI tools-Bolna, Vapi, ElevenLabs, or similar

You've vibe-coded something: a small automation, a chatbot, a no-code workflow-anything

Experience in a customer-facing role, even informally (sales, support, intern, freelance)

Familiarity with how LLMs work under the hood-context windows, temperature, hallucination, etc.

Why Bolna

The hottest team in the hottest market in India right now

Freshers who joined 3 months back are single-handedly working with CXOs and Senior PMs of massive enterprises

Direct access to founders and product-your work will visibly ship

You'll develop a rare, high-value skill set at the intersection of AI, product, and customer success
