Fouding engineer

About usEvery business runs on hard work: answering phones, chasing documents, booking, reminding, following up. Within a few years, agents will do most of it. We are building the operating system that makes that happen.We start in specialty healthcare, where the work is hardest and the stakes are highest. Our agents already answer phones, call patients, book appointments and handle crucial communication in clinics today. They finish the work across EHRs, practice management systems, telephony and messaging, and show every step they took. If it works in a clinic, it works anywhere.From there we expand clinic by clinic and vertical by vertical, until businesses across Europe and the US run on us. Agentic software is the next platform shift, and we intend to be at the front of it.The founders have done this before. Between them they have started three successful companies, raised more than 25 million and served millions of customers. One brings deep access to the healthcare sector. Another built a European AI company to more than 100 people and profitability. We grow fast and capital efficiently: revenue first, a small senior team, and as much leverage from AI as possible. We are deliberately under the radar for now. That will not last long.The roleYou join the founding team. You help shape the product, the architecture and the culture from the first lines of code, with the equity to match.In healthcare, a demo that works 90% of the time is a liability. A booking that never reached the calendar means a patient misses care. A message sent without consent is a compliance incident. Reliability is the product, and you own it.You build two things:The factory. Agent loops that take a spec to a tested pull request, evals that decide what ships, and agents that review other agents. Speed matters, but nothing merges without proof that it works.The product. The agent platform clinics run on: workflow orchestration that recovers when a call drops or an API fails, integrations with EHR, practice management, telephony and messaging systems, deterministic guardrails for consent, escalation and write-backs, and monitoring that catches failures before a clinic does.What you bring3+ years shipping production software that you owned, including being responsible when it brokeStrong TypeScript and NodeReal experience building with LLMs: tool use, agent loops, and evals you trusted enough to block a releaseExperience making unreliable third-party systems behave reliablyDaily use of coding agents, and a clear sense of where they breakProduct judgment and the drive to build a company from the ground upNice to have: voice AI or telephony, FHIR, HL7 or EHR integrations, early-stage startup experience, Dutch.What we offerFounding equity and a competitive salaryA seat at the founding table: you decide how we build, who we hire next and how engineers work alongside agentsAmsterdam, on-site, working with the latest models and tools
