We’re building a world of health around every individual — shaping a more connected, convenient and compassionate health experience. At CVS Health®, you’ll be surrounded by passionate colleagues who care deeply, innovate with purpose, hold ourselves accountable and prioritize safety and quality in everything we do. Join us and be part of something bigger – helping to simplify health care one person, one family and one community at a time. At CVS Health, our purpose is to deliver better health outcomes by meeting consumers where they are—through local care, digital experiences, and a nationwide team committed to quality, safety, and affordability. Our Solutions Engineering and Infrastructure organization is building an enterprise AI/ML capability that delivers reliable, responsible, and secure AI-powered platforms and solutions at Fortune 5 scale, and this role is foundational to help us develop that capability. This is a senior individual-contributor role, focused on identifying evaluating and documenting high-value use cases, designing and prototyping AI-powered solutions, and evolving them into secure, resilient, enterprise-ready products and platform components.
Job Responsibility:
Partner with stakeholders to identify, evaluate, document, and shape GenAI use cases (copilots, automation, decision support, and insight generation) with clear success metrics
Design solution architectures that integrate LLMs with enterprise systems, data sources, and tool/function calling while meeting latency and reliability expectations
Develop prototypes rapidly and validate them through evaluation, red-teaming, and user feedback
document tradeoffs and recommendations
Build production-grade services and full-stack experiences (APIs, UIs, workflows) with secure authentication/authorization, audit logging, and scalable deployment patterns
Implement safety, privacy, and compliance controls (e.g., PHI/PII protection, prompt injection defenses, data residency constraints, and policy-based filtering)
Instrument solutions end-to-end with metrics, traces, logs, and model/app observability
contribute to SLOs, error budgets, and operational runbooks
Build and maintain evaluation harnesses for LLM quality, safety, and business outcomes (offline tests, golden sets, regression suites, and online experiments)
Implement RAG pipelines (chunking, embedding, vector search, reranking) and optimize for accuracy, cost, and latency
Collaborate with platform teams on deployment, monitoring, drift/quality detection, and incident response for model-backed services
Contribute reusable libraries and patterns for prompt management, retrieval, tool calling, and policy enforcement
Participate in design reviews and code reviews
mentor senior and mid-level engineers on GenAI engineering practices
Continuously improve developer experience through templates, CI/CD automation, and documentation that accelerates safe adoption
Requirements:
7+ years of software engineering supporting Data or AI/ML initiatives, including building and operating production services
3+ years applying ML/AI in production
demonstrated hands-on GenAI delivery (LLMs, RAG, evaluation, and safety controls)
3+ years of experience delivering solutions in high-scale, high-availability environments with strong security and compliance requirements
Bachelor’s degree or equivalent experience (High School Diploma and 4 years relevant experience)
Nice to have:
Strong full-stack engineering skills (backend services, APIs, and modern web application development) with a focus on reliability and security
Hands-on expertise with LLM application patterns: RAG, tool/function calling, prompt management, evaluation, and guardrails
Experience with Python and at least one additional backend language
familiarity with common ML libraries and serving frameworks
Working knowledge of containerization and Kubernetes, CI/CD, infrastructure-as-code concepts, and production observability
Ability to communicate clearly, influence across teams, and translate business needs into implementable technical plans
What we offer:
Affordable medical plan options
a 401(k) plan (including matching company contributions)
an employee stock purchase plan
No-cost programs for all colleagues including wellness screenings, tobacco cessation and weight management programs, confidential counseling and financial coaching
