About Kerry Care
Kerry Care is a US-based healthcare technology startup building AI-powered systems to improve senior care delivery. We're early stage, mission-driven, and moving fast to solve real problems in how care is coordinated and delivered.
We are looking to hire our Founding Engineer— the person who will own our technical architecture and set the engineering standard for the company.
You'll be working with two other developers, but you are the senior engineer. You'll make the key technical decisions, build the core systems, and establish how we build software. This is not a management role — you'll be hands-on, writing code daily, and leading through technical excellence.
This is a startup. That means ambiguity, pressure, direct access to founders, and real responsibility. You'll need to be highly driven and deeply interested in either AI systems, senior care technology, or both. It's a demanding role, but you'll work with smart people who care about the mission and you'll get direct exposure to how US startups actually operate.
