The Senior Full Stack Engineer is a hands-on technical lead role. This role has broad scope across the full stack, including front-end, back-end, database, integrations, and hosting, for the Wisconsin Medicaid Market. The role emphasizes autonomy and ownership while setting technical direction, driving platform consistency, and mentoring engineers to deliver reliable, scalable solutions.

This position blends day-to-day software engineering with technical leadership. It involves modernizing legacy systems, reducing technical debt, and establishing consistent platform patterns. These efforts span across two independent health plan technology stacks. The role also promotes modern engineering practices (CI/CD, infrastructure and security as code, automated testing, and observability) and expects responsible use of Humana-approved AI and code generation tools to accelerate delivery and improve quality.

The Senior Full Stack Engineer is responsible for design, development, and modernization of applications and platforms that support the Wisconsin Medicaid Market. This role operates with a high degree of autonomy and trust, owning solutions end-to-end across the full stack rather than being confined to a single application or technology area.

The Wisconsin Medicaid Market IT team functions as a highly empowered, end-to-end technology organization supporting two acquired health plans with independent core administration systems and technology stacks. As a result, this role works across the full spectrum of core platforms and supporting systems—collaborating with peers, enterprise architecture, and platform partners to define technical direction, align to enterprise standards where appropriate, and reduce system complexity and operational burden.

This position regularly wears multiple hats—building and modernizing software across front-end, back-end, database, integration, and hosting layers; contributing architectural vision; addressing technical debt; and improving reliability and scalability across environments. The engineer will lead by example through hands-on delivery, strong code review practices, and mentoring. Additionally, they will drive software-driven automation, focusing on CI/CD, infrastructure, and security as code. Furthermore, they will adopt cloud-native patterns, such as containers and orchestration, where they fit the market's needs.

The role will also champion practical, responsible use of Humana-approved AI-assisted development and code generation tools (Google-based tooling in Humana's standard stack) to increase throughput and strengthen code quality.

Success in this role is driven not only by technical outcomes, but also by how the individual shows up: bringing curiosity, ownership, collaboration, and a growth mindset. This role is well suited for a lead engineer who can translate ambiguous requirements into pragmatic designs, communicate tradeoffs to technical and non-technical stakeholders, mentor teammates through design and delivery, and progressively take on broader platform and architecture responsibility while remaining hands-on.
