Freelance Integration Developer | Apache Camel + Quarkus LIS Integration Gateway

About Vitestro Founded in 2017 in Utrecht, Vitestro is pioneering the future of blood collection with the Aletta® Autonomous Robotic Phlebotomy Device™ (ARPD™) . This groundbreaking medical device combines advanced multi-modal imaging (near-infrared, ultrasound, and Doppler ultrasound) with robotics and AI to perform the entire diagnostic blood draw procedure autonomously. By addressing critical healthcare staffing shortages and improving patient experience, Vitestro is transforming one of the most common and essential medical procedures. With more than 90 team members and growing rapidly, we are scaling our impact. As we placed our first devices with customers, we are now expanding our team to ensure successful implementation and long-term reliability. At Vitestro, we are committed to continuous innovation and improvement. The Assignment Vitestro is building the LIS (Laboratory Information System) integration gateway that connects hospital laboratory systems to our venipuncture device platform. We have selected Apache Camel on Quarkus as the target architecture: a stateless, container-per-hospital gateway that can run centrally in AWS or on-premise at a hospital, with hard OS-level data isolation between tenants and zero-code onboarding of new hospitals via configuration. Our internal Platform & Connectivity team does not have the capacity to deliver this build within our commercial timeline, so we are looking for an experienced freelancer/contractor (or small team) to build the initial gateway. A permanent Integration Engineer will take over operation, maintenance, and hospital-by-hospital rollout once the gateway is delivered — so a clean, well-documented handover is a hard requirement of this assignment, not an afterthought. Key Deliverables Design and build the universal, stateless Camel + Quarkus gateway image: one codebase, hospital identity/config/transformations externalized and injected at container boot Implement the reliability properties required for cl
