Senior Full Stack Engineer

Become a part of our caring community   The Senior Full Stack Engineer – Platform & Architecture 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 architecture-minded decision making, 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 – Platform & Architecture is responsible for hands-on architecture, 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. Skills & Capabilities Full Stack Application & Platform Engineering Deep experience building and modernizing applications across the full stack, including front-end, back-end, data, integrations, and hosting. Strong experience with the Microsoft technology stack (e.g., .NET, SQL Server, Windows-based services) and cloud-hosted solutions (especially Azure). Comfortable working across application, integration, and platform layers in complex environments. DevOps, Automation, and Infrastructure/Security as Code Experience designing delivery pipelines and operational automation (CI/CD), applying infrastructure as code and security as code practices, and improving developer experience through repeatable, self-service patterns. Cloud-Native Patterns (Containers & Orchestration) Working knowledge of containerization and orchestration concepts (e.g., Docker and Kubernetes/AKS) and when to apply them to improve scalability, resilience, and consistency across environments, especially Azure. Reliability, Observability & Operational Excellence Ability to improve production supportability through monitoring, logging, alerting, and runbook-style documentation; experience reducing incident volume via root-cause analysis, automation, and resilient design. Cross‑Domain Systems Thinking Ability to understand and navigate interactions across multiple insurance core systems, platforms, and supporting services, identifying opportunities to simplify workflows and reduce system sprawl. Architecture‑Minded Engineering Strong aptitude for evaluating existing solutions, identifying technical debt, and recommending pragmatic architectural improvements that balance near‑term delivery with long‑term sustainability. Modernization, Reliability & Code Quality Experience modernizing legacy technologies and improving reliability, performance, and operational supportability through thoughtful design, refactoring, and automation. AI‑Assisted Development & Code Generation Comfort actively leveraging AI‑assisted development and code generation tools to improve productivity, code quality, analysis, and learning. Expected to use these tools day‑to‑day and model effective practices for the team. Experience with Humana's approved code generation tooling (e.g., Windsurf/Codeium) is highly preferred; strong aptitude and willingness to learn is equally valued. Ways of Working & Mindset Thrives in autonomous, high-trust environments. Comfortable wearing multiple hats, collaborating across teams, influencing through expertise, and remaining hands-on while leading technical direction, mentoring teammates, and partnering with leaders on architectural and process decisions.
