Fortune 50 Health Insurance Client

Our client is seeking a Senior Full Stack Engineer to join their digital organization and play a key role in the modernization of critical healthcare applications. This engineer will design, develop, test, and deploy scalable, high-quality web applications across the full technology stack.

The team is modernizing legacy systems using a modern cloud-native architecture and technologies including Type Script, Node.js, Express.js, GraphQL, and Azure Cloud. The ideal candidate is a versatile, hands‑on engineer who can independently own the full development lifecycle while also providing technical leadership and helping establish modern engineering practices across the team.

This role will support a rewards program that encourages Medicaid and Medicare members to be proactive about their health. The team operates in an Agile/Scrum environment with two-week sprints and participates in PI Planning.

The Senior Full Stack Engineer will work closely with product managers, designers, engineers, and other stakeholders and should be a strong communicator who is comfortable speaking up, driving technical discussions, and providing leadership from the front.
