Company Description:
FluidAI is specialized in the development and deployment of data-driven surgical solutions, with an initial focus on general and gastrointestinal surgery. Our technologies integrate medical devices, software, and artificial intelligence into platforms that address real clinical and operational challenges across the continuum of surgical care.
We combine continuous physiological monitoring from our proprietary sensors with comprehensive electronic health record data, creating intelligent systems that enable earlier identification of clinical deterioration and complications. Beyond patient monitoring, our platform extends to patient education and engagement tools, as well as automated documentation and coding modules — supporting care teams and driving operational efficiency.
Our team brings together expertise across clinical practice, research, engineering, data science, manufacturing, and commercialization. We build solutions designed for real-world impact, supported by full in-house capabilities, a strong intellectual property portfolio, and partnerships with leading institutions around the world.
We are an equal opportunity employer and have a diverse team representation across language, ethnicity, gender and nationality.
Why Join FluidAI Medical?
- Mission to save lives and improve patient care with technology that’s already deployed on patients in real-world settings.
- Work with a high-performing and cross-functional team that is empowered to grow, learn, and contribute across all levels of the organization.
- Gain exposure across the entire technical stack, from novel sensing technologies and proprietary hardware to mobile/web software and ML algorithms.
- Personal career-focused development and training with access to workshops, coursework, and experienced mentors/consultants.
- Regular offsite activities – past events include rafting, cottaging, axe-throwing, sports leagues, and the usual BBQ.
Job Summary:
FluidAI Medical is at the forefront of integrating data, technology, and healthcare to improve patient outcomes. Our platform connects proprietary sensing hardware, mobile and web applications, and ML algorithms to deliver real-time clinical insights at the bedside. We are expanding our team to include a Senior Backend Engineer who can own the design and evolution of the backend systems that power this platform, from device data ingestion and clinical APIs to the integrations, infrastructure, and reliability that a medical-grade product requires.
We work in a full-stack environment, where engineers own features end-to-end. Alongside backend ownership, this role works directly in our React, Next.js, and React Native codebases. That includes building and connecting the APIs, data flows, and real-time updates that bring our web and mobile applications to life.
