Senior Product Engineer

Talkie

6d • Remote

About The Position

Talkie builds AI Agents for healthcare. Our agents handle patient-clinic communication end-to-end over voice calls, web chat, and SMS, so patients get 24/7 access to care and busy practices never miss a conversation. Every month, our AI Agents handle close to a million real patient conversations across the US and Poland. Our customers include primary care and specialty practices, and hospitals.

The role We're looking for a Senior Product Engineer to join our Platform team. You'll build the features that power our AI Agents, in the backend and the UI. Much of that work touches telephony, clinical systems such as EHRs, and LLMs. You'll own features until they run in production. You research the problem and shape requirements with our CPO. You propose the interaction and UI, design the architecture, build it across the stack, ship it, and watch how it behaves with real patients on real calls. You'll work alongside other Engineers, take requests from our Customer Success and Conversation Design teams, and work with many people across the product organisation. Our engineers work with many AI agents at once. One agent implements a feature, another reviews it, and a third digs through logs or researches an unfamiliar API. This role requires fluency in that way of working.

Requirements

• Product ownership. You've shipped and owned a product or major features in production, end-to-end. When the path isn't clear, you find one.
• Strong architectural experience. You build software that stays easy to change and maintain as it grows, and you can explain the trade-offs behind your decisions.
• Fullstack TypeScript. You have solid hands-on experience with Node.js on the backend, React on the frontend, and MongoDB or another database.
• Cloud and infrastructure as code. You have hands-on experience with AWS or another major cloud provider, and with IaC tools. We use Terraform and Pulumi.
• AI-native development. Coding agents are your main way of working, as described above, and you can show us how you use them.
• LLM integration in production. You've built LLM-powered features with evals, and made informed latency and cost trade-offs.
• Healthcare compliance awareness. You understand what building software under SOC2 and HIPAA means in practice, and how it shapes decisions about data, access, and logging.
• Product sense for UI. You can propose a user interaction and design a clean UI without a detailed mockup.
• English. You speak and write English at C1 level or above. Most of our written work is in English, and our customers are in the US.

Nice To Haves

• Telecom. You've worked with SIP, call routing, or VoIP. If you haven't, that's fine. When you hear "SIP integration", we want your reaction to be "I'll learn it", followed by a plan for a prototype.
• EHR or other healthcare integrations. You've worked with clinical systems or other regulated domains with many integrations.

Responsibilities

• Own product features end-to-end. Research the problem, refine requirements with the CPO, propose the user interaction, and design a clean, usable UI. Then build it, ship it, and monitor it.
• Build across the stack. You'll write backend services and APIs in TypeScript and Node.js, frontend in React, and AWS infrastructure as code.
• Integrate LLMs into the product. Design how our agents use models and tools. Build evals that show whether a change made things better, and trade off quality, latency, and cost on purpose.
• Integrate with outside systems. Our agents depend on SIP telephony and call routing, EHR systems, LLM providers, and other services.
• Shape technical and architectural decisions. Take part in the team's design discussions, write and review technical proposals, and help set the direction of the platform. Keep it easy to change and maintain, and make sure it handles real-time calls efficiently.
• Mentor other engineers. Review their designs and code, pair with them on hard problems, and help them grow, including in how they work with agents.
• Turn open questions into plans. When a new problem or technology comes up, form a hypothesis, build a prototype, and measure it. Then come back with a list of trade-offs and a proposal the team can build on.
• Keep production healthy. Monitor what you ship, cut alert noise, and find and fix performance bottlenecks.
• AI-native development This is how we work every day, and we expect you to help us improve it.
• Orchestrate agents. You run several coding agents in parallel for implementation, code review, log and incident investigation, and research. You know how to direct them, check their output, and correct it.
• Improve the codebase for agents. You know what makes a codebase easy for agents to work in, such as clear module boundaries, good agent instructions in AGENTS.md or CLAUDE.md , and fast feedback loops. You make ours better.
• Build skills and agent workflows. You write and maintain reusable skills, commands, and workflows that encode how the team works, so agents get it right the first time.
• Share what works. You teach the team effective agent workflows, and you know when not to trust the output.

Benefits

• Competitive pay with your choice of employment contract or B2B contract.
• A role with real purpose. We're changing how patients access healthcare in the US and Poland.
• Flexible working arrangements. Work remotely from anywhere in Europe, from the office, or hybrid.
• Work equipment for both home and office, including a comfy chair.
• Private medical care, a Multisport card, an annual offsite, and a training budget.
• A structured onboarding, plus mentoring and support as you get into AI and conversation design.
• Work on AI products that help real patients reach care.
