Senior AI/ML Engineer (Remote - US-Based)

Join us to Improve Health Equity for 5 Million People!

CareMessage is the technology non-profit building the largest patient engagement platform for low-income populations in the United States. Powered by the Health Equity Engine™, the platform enables organizations to combine messaging, data, and interoperability to increase access to care, improve clinical outcomes, and address social drivers of health.

With 20 million patients reached since 2013, CareMessage is the only patient engagement solution proven to improve health equity at scale. The team, many with lived experiences in these communities, leverages a nonprofit model to reinvest revenue into impact. CareMessage is the partner of choice for organizations committed to advancing health equity.

CareMessage is seeking a talented and experienced Senior (L3) AI/ML Engineer to join our dynamic data team. As an AI/ML Engineer specializing in healthcare, you will have the opportunity to work on cutting-edge projects that leverage artificial intelligence and machine learning in the areas of clinical outcomes, increased access to care, and improvements in Social Determinants of Health for people from low-socio-economic backgrounds.

As an AI/ML Engineer at CareMessage, you will play a crucial role designing, building, and deploying machine learning models and AI-powered systems that help drive better decision-making across our platform. As a key strategic investment for the company and product, you will be working on highly impactful and visible outcomes similar to the AI Assistant we recently released. This is an opportunity to be at the forefront of spurring insight and innovation through the use of machine learning, artificial intelligence, and data to drive strategic impact and decision making throughout CareMessage. One of the goals of this team is to leverage machine learning and AI to analyze patient interactions with CareMessage, enabling us to extract actionable insights and build intelligent systems that will drive measurable and scalable improvements for the populations we support.

You will work closely with a multidisciplinary, agile team to identify key problems, design AI/ML solutions, preprocess and clean data, build and test machine learning models, interpret results, and deploy models into production. These solutions will harness the organization’s connected data, enabling intelligent, data-driven decision-making and automated actions. This is an exceptional opportunity for someone with a passion for machine learning and AI, and a desire to make a significant social impact.

If you share our mission-driven commitment to advancing health equity for individuals of low socio-economic status nationwide and have a strong understanding of machine learning algorithms, data processing, along with a passion for using technology to improve healthcare outcomes, we would love to hear from you.

Note: Due to the nature of this role we are only accepting US-based candidates. At this time, we are not able to sponsor work visas. Applicants must be authorized to work in the United States on a full-time basis without sponsorship.
