Position Summary:

If you're eager to make a real impact in the healthcare industry through meaningful contributions, explore a role in technology with CVS Health. Our journey calls for technical innovators and UI visionaries: come help us shape the future of care delivery.

At CVS Health, we are driven by a vision to redefine healthcare in America by placing people at the forefront of everything we build. We're seeking an experienced, hands-on full stack engineer with a strong UI background who shares our commitment to engineering excellence and innovation. As part of our Utilization Management (UM) team, you'll have the opportunity to contribute to modernizing and advancing technologies that directly impact patient care and clinical workflows.

As a Staff Full Stack Engineer at CVS Health, you'll serve as the technical leader for the UM squad - owning the end-to-end delivery of high-quality software that enhances clinician and member experiences. This is a deeply hands-on role: you will be writing, reviewing, and owning production code every day while simultaneously leading the squad. You'll drive all phases of software engineering, from requirements analysis to production deployment, while championing agile methodologies and engineering best practices. You will be the go-to technical authority for the squad, mentoring engineers, making architectural decisions, and ensuring the team delivers with quality on aggressive timelines.

In this role, you will:

• Lead the UM squad technically end-to-end - setting direction, removing blockers, and owning outcomes across the full stack.
• Actively write and contribute production-quality code daily - this is a hands-on engineering leadership role.
• Drive UI architecture and development for the UM application, with a strong emphasis on building intuitive, accessible, and performant front-end experiences using React or Angular.
• Be hands-on in the development process, actively contributing code and guiding junior developers through debugging and delivery.
• Design, implement, and integrate LLM-based solutions into UM workflows, applying hands-on knowledge of ML concepts such as prompt engineering, fine-tuning, embeddings, and retrieval-augmented generation (RAG).
• Architect and manage complex microservice frameworks, ensuring services are well-defined, independently deployable, resilient, and observable at scale.
• Partner with product managers and clinical stakeholders to translate complex UM workflows into clear, user-centered requirements and designs.
• Own architectural decisions across both UI and backend systems, ensuring scalability, maintainability, and reliability.
• Perform release management and coordinate deployments across environments.
• Champion observability, testing, and operational excellence to ensure 24/7 uptime for critical healthcare workflows.

Required Qualifications:

• 5+ years of full stack software engineering experience, with demonstrable depth in UI/front-end development (React or Angular required) and back end services.
• 5+ years of experience in one or more modern languages such as Python, Java, TypeScript, or JavaScript - with a track record of writing and owning production code.
• 5+ years of experience building APIs, microservices, and modern software patterns; including hands-on experience designing and operating complex microservice architectures at scale.
• 5+ years of experience with CI/CD pipelines, containerized applications, and UI frameworks (React/Angular).
• 2+ years of hands-on experience with LLM implementation - including integrating large language models into production applications, prompt engineering, and working knowledge of ML concepts such as embeddings, RAG, fine-tuning, or model evaluation.
• 2+ years of experience in the GCP ecosystem with hands-on development using BigTable, Spanner, GKE, and Cloud Functions.
• 2+ years of experience building observable, fault-tolerant systems for 24/7 availability.
• 2+ years of experience leading or mentoring a squad or team of engineers, driving delivery on complex initiatives.
• 1+ year of experience gathering complex requirements and managing relationships with business and clinical stakeholders.

Preferred Qualifications:

• Proven ability to lead a full squad independently - setting technical standards, unblocking engineers, and owning delivery - while remaining a active, contributing engineer.
• Strong UX sensibility with experience designing workflows for complex enterprise or clinical applications.
• Familiarity with microservice patterns such as service mesh, event-driven architecture, circuit breakers, and distributed tracing.
• Experience with AI/ML frameworks and tooling (LangChain, LlamaIndex, Vertex AI, OpenAI APIs, HuggingFace, etc.).
• Familiarity with all phases of the software development lifecycle (SDLC).
• Excellent written and verbal communication skills, with the ability to translate technical decisions for non-technical partners.
• Experience with GCP architecture, optimization patterns, and data engineering.
• Working knowledge of CI/CD tools: GIT, Bitbucket, Artifactory, Jenkins, etc.
• Previous healthcare or utilization management domain knowledge strongly preferred.

Education:

Bachelor's Degree or equivalent work experience in Computer Science, Information Systems, Data Engineering, Data Analytics, Machine Learning, or related field required. Master's Degree preferred.
