About Kontakt.io
Inside health systems, where every second can matter, operations are still spread across dozens of disconnected tools and platforms. Kontakt.io is changing that.
We combine proprietary hardware, AI-powered intelligence, and deep integrations with the technology health systems already have in place to build real-time understanding of what's happening across their operations. That intelligence becomes the execution layer care teams have been missing, helping them make smarter decisions and deliver better patient care.
Backed by Goldman Sachs and trusted by leading health systems including HCA Healthcare, Sutter Health, AdventHealth, Trinity Health, Northwell Health, Cleveland Clinic, and the U.S. Department of Veterans Affairs, we've more than doubled our revenue and are rapidly scaling with a clear path toward $100M in annual recurring revenue.
If you're excited to solve hard problems and help health systems deliver better care, we'd love to meet you!
As a Data Science Lead, you will play a pivotal role in designing, developing, and deploying machine learning models that drive AI-powered automation across healthcare operations. You will own end-to-end ML lifecycle management, ensuring operational excellence, measurable business impact, and collaboration with cross-functional teams. Your work will enable hospitals and healthcare facilities to deliver better, faster, and more cost-effective care.If you're passionate about building impactful ML solutions, leading data science teams, and transforming care delivery operations, join Kontakt.io and help us redefine the future of healthcare!

Identify high-value data sources and upstream improvements to improve model outcomes or enable new capabilities meaningfully.
Ensure all initiatives are tied to clear metrics or business KPIs.
