AI Engineer – Voice AI

HelloCounsel builds AI agents that run pre-litigation for US personal injury firms: intake, case opening, medical records, insurance claims, client communication. They work across phone, email, fax and the firm's case management system. Live at real firms, $3.2M seed. The phone is where a PI case starts, and where it's most often lost. A missed or fumbled call is a client who signs with another firm. THE ROLE You own our voice agents end to end: the ones that answer a firm's intake line, call clients back with updates, and call insurers and medical providers to chase claim numbers and records. Real calls with real people who are hurt, stressed or busy. You make them sound human, stay accurate, and get the task done. Nobody hands you a spec. WHAT YOU'LL DO - Build and run the voice stack: telephony, speech-to-text, LLM, text-to-speech, turn-taking, interruptions, warm transfers to humans - Push latency down and task completion up, call by call. Listen to the calls. - Build evals and replay harnesses from real calls, so every change is measured before it ships - Crack the hard calls: insurer IVR menus and hold queues, voicemail, accents, crosstalk, callers in distress - Ship every week and own the numbers: completion rate, latency, escalations, cost per call YOU'RE A FIT IF - You've shipped a voice agent or real-time speech system that real people called, and you know exactly what broke - You know the stack (SIP/Twilio, Deepgram/Whisper, ElevenLabs/Cartesia, LiveKit/Pipecat or your own) and can go below the framework when you need to - You write production code (Python or TypeScript) and debug with logs and recordings, not guesses - You'd rather own an outcome than a ticket queue YOU'RE NOT A FIT IF - You've only built demos - You need a spec before you start HOW WE HIRE A short written problem, a call with the founder, then a small build: a working voice agent. We judge how you get past obstacles, not polish. In office, Bengaluru.
