Conversational AI Specialist - US market

About us

Talkie builds AI Agents for healthcare. Our technology handles patient-clinic communication end-to-end — across voice, web chat, and SMS — so that patients get access to care 24/7 and busy practices never miss a conversation.

Who uses Talkie?

Every month our AI Agents engage in over half a million conversations with real patients across US and Poland — over voice, web chat, and SMS. Our technology is trusted by primary and acute care, specialty practices, as well as private and public hospitals.

Who are we hiring?

We’re looking for a Conversational AI Specialist for our US product — someone who will own the quality and intelligence of our AI Agents from prompt to production. This is a role at the intersection of language, technology, and healthcare, where your work directly impacts hundreds of thousands of real patient conversations every month.

As a Conversational AI Specialist, you will:

• Design, write, and continuously optimise prompts that power our AI Agents — making them natural, accurate, and reliable.

• Analyse real patient–agent conversations end-to-end, identifying failure patterns, edge cases, and opportunities to improve agent behaviour.

• Propose and implement technical solutions around function calling, tool use, context caching, and other LLM capabilities that make our agents smarter.

• Build and run evaluation frameworks to test agent performance before and after changes — because every conversation is with a real patient and there is zero margin for error.

• Create clear, structured documentation and customisation instructions so that agents can be tailored to each client’s specific workflows and needs.

• Stay on top of the rapidly evolving LLM landscape — new models, techniques, and conventions — and bring the best ideas back to the team.

• Work closely with the Product Manager (US market), engineering, and client teams to ensure agent quality across all deployments.

What will you achieve with us?

• Shape the experience that hundreds of thousands of patients have when they reach out to their doctor — across every channel — and make it better every single day.

• Push the boundaries of what LLM-powered AI agents can do in a highly regulated, real-world, multi-channel environment.

• Build evaluation and quality systems for conversational AI that don’t exist yet — you’ll be creating the playbook.

• Have a direct, measurable impact on patient access to healthcare in both the US.

Requirements

This is a young and fast-moving field. We care less about years of experience and more about how you think, learn, and work.

Must have

• LLM Fluency — You understand how LLMs work and have hands-on experience writing and iterating on prompts for production systems. More importantly, you learn fast — this field changes weekly and you keep up. You know the difference between a clever hack and a robust, reliable solution.

• Analytical Rigour — You can review hundreds of conversations and extract patterns, failure modes, and actionable insights. But you don’t stop at the data — you validate your findings on calls with clients and the implementation team, and turn them into concrete improvements.

• Communication & Collaboration — This is not a “sit in a cave and prompt all day” role. You’ll be on calls with clients, supporting the implementation team, explaining agent behaviour, and iterating with product and engineering. You communicate clearly, listen well, and can translate between technical and non-technical worlds.

• Multitasking & Proactivity — You juggle multiple clients, agents, and improvement threads at once without dropping the ball. You don’t wait to be told what needs fixing — you spot issues, flag them, and propose solutions. You serve multiple stakeholders: the implementations team, clients, and ultimately the patients themselves.

• Zero-Error Mindset — Our agents talk to real patients. You understand the weight of that responsibility and bring the precision and care it demands.

• Human-Like Perfection — You obsess over making AI conversations indistinguishable from talking to the best human receptionist — or even better. You notice the tiny details that make a response feel natural: phrasing, pacing, empathy, context. You’re never “good enough” and always looking for that one small tweak that makes a real difference.

• Drive & Curiosity — This field changes weekly. You’re the kind of person who reads release notes, experiments with new models on weekends, and brings fresh ideas to Monday’s standup.

• English — You are fluent in English (at least C1), with strong written skills. Knowledge of another language is a plus, but not a must.

• Shifted Hours — You are available to work 12:00–20:00 CET at least 3 days per week (optimally 5) to overlap with US Eastern Time business hours.

Great to have

• Function Calling & Tool Use — Experience designing or working with LLM tool-use patterns, structured outputs, and API integrations.

• Evaluation Frameworks — Familiarity with tools and approaches for testing conversational AI (e.g. Braintrust, DeepEval, LangSmith, or custom eval pipelines).

• Multi-Channel AI Experience — Understanding of the nuances of AI across different channels: voice (latency, turn-taking, TTS/ASR), web chat (UX patterns, async flows), and SMS (brevity, compliance).

• Documentation Skills — You can write clear, structured instructions that other team members and clients can follow without hand-holding.

Nice to have

• Healthcare — Prior experience in healthcare, health-tech, or other regulated industries where accuracy and compliance matter.
