AI Scientist Intern

Cambia Health Solutions•Renton, WA

6d•Hybrid

About The Position

This internship is a 12-week, full-time position starting in May or June 2026 Pay Rate: $39.40/hour Candidates will be required to reside in Oregon, Washington, Idaho, or Utah for this internship, with options to work in person/remote/hybrid. Internship MUST be performed within Regence’s 4-state footprint. This position is not open to candidates who require sponsorship for employment status now or in the future. Who We Are Looking For: AI Scientists work with various stakeholders to design, develop, and implement data-driven solutions. This position applies expertise in advanced analytical tools such as machine learning, deep learning, optimization, and statistical modeling to solve business problems in the healthcare payer domain. AI Scientists’ work may focus on a particular area of the business such as clinical care delivery, customer experience, or payment integrity, or they may work across several areas spanning the organization. In addition to expertise in analysis, machine learning and deep learning, this role requires knowledge of data systems, basic software development best practices, and algorithmic design. AI Scientists work closely with AI team members in the Product and Engineering tracks to collaboratively develop and deliver models and data-driven products. AI Scientists also collaborate and communicate with business partners to design and develop data-driven solutions to business problems and interpret and communicate results to technical and non-technical audiences. As an intern you would work under the mentorship of another AI Scientist on some/all parts of the AI/ML lifecycle. This can be a feature in an existing product or on Proof-Of-Concepts (POCs) for a new or existing initiative.
