Description

At Vironix (http://www.vironix.ai), we are out to make the world a healthier place and move the needle in the delivery of healthcare which is one of the most pressing problems facing society today. Vironix Health leverages state of the art AI to deliver real-time remote monitoring, and detection of health deterioration due to viral and chronic illness. Our team, composed of esteemed scientists and technologists, is dedicated to pioneering work that stands at the forefront of healthcare and AI. We have a very small team of superstars, and are on a rapid trajectory of hypergrowth and have a few select openings for only the very best talent. We're hiring a Full-Stack Engineer who will own the backend services that power Vironix's care platform — API design, data integrity, and the reliability of the systems clinicians depend on. You're not a specialist: you can navigate a React codebase, ship a frontend change when needed, and aren't blocked by a UI task. You'll work closely with our CTO on infrastructure decisions and take on informal technical leadership as the team scales — unblocking others, owning delivery, and raising problems before they become incidents. Our core team is based in Austin, TX. We work a hybrid schedule with a few days of in-person collaboration each month. We're looking for candidates already based in Austin, TX. Requirements You've built and owned production backend services - Python experience preferred. Solid SQL and PostgreSQL skills; you care about query correctness and performance Hands-on GCP or comparable cloud platform experience; GKE familiarity is a strong plus Comfortable navigating a React/TypeScript codebase and shipping frontend changes when called for Prior startup experience preferred — you've owned delivery end to end, not just a ticket queue The maturity to lead informally: you raise problems early, unblock teammates, and operate without a playbook Strong judgment on when to move fast and when to slow down and do it right Based in Austin, TX or willing to relocate Benefits Competitive salary, depending on experience Equity participation in a high-growth healthtech startup Comprehensive health, dental, and vision coverage Hybrid work model — flexibility with intentional in-person collaboration Direct impact on a product used in real clinical care Small team, high ownership — your architectural decisions matter and ship A culture that values efficiency and results over hours logged #ZR

Responsibilities
