CVS Health is looking for a Principal Engineer - Digital to serve as one of the most impactful individual contributors in the organization. This is a role for someone who can see, shape, and set the technical direction of our entire digital ecosystem.

You will be part of the team that has the technical authority across mobile (iOS & Android), web, cloud infrastructure, AI/ML platforms, backend systems, security, developer tooling, and agentic AI. You will define architectural standards, evaluate emerging technologies, mentor senior engineers, and make the high-stakes technical decisions that no single product team can own alone.

If you thrive at the intersection of systems thinking, deep technical craft, and organizational influence — and want your work to touch the health of tens of millions of Americans every day - this is the role for you.

Define and own the end-to-end digital architecture strategy, ensuring coherence and consistency across mobile, web, cloud, and AI surfaces

Author and steward Architecture Decision Records that guide engineering decisions across multiple teams and domains

Evaluate and validate major architectural choices — service boundaries, data models, API contracts, and infrastructure patterns — before they become expensive to change

Identify and eliminate architectural debt proactively, balancing short-term delivery pressure with long-term platform health

Establish and enforce engineering standards, design principles, and best practices across the full digital portfolio

Drive technology radar decisions — selecting, adopting, and deprecating frameworks, tools, and platforms across the organization

Define web architecture standards including application framework selection, rendering strategy (SSR, CSR, ISR), and micro-frontend approaches where appropriate

Lead performance engineering for web:
Core Web Vitals targets, bundle optimization, lazy loading strategy, and CDN/edge caching architecture

Govern third-party script strategy to protect page performance, user privacy, and security

Define the organization's AI architecture strategy across the full spectrum - foundational model selection, inference infrastructure, vector databases, embedding pipelines, and responsible AI design patterns

Ability to build and strategize AI systems to be consumed for Mobile apps/Web and the personalization, recommendations using the data analysis and AI/ML tools

Lead agentic AI system design using orchestration frameworks (Lang Chain, Lang Graph, Auto Gen, or equivalent), including agent loop design, tool use, memory, and guardrails

Ensure all AI systems meet explainability, fairness, and compliance requirements - particularly in a regulated healthcare context.

Identify AI solutioning opportunities across the digital product portfolio and drive proof-of-concepts through to production-grade implementation.

Architect scalable, resilient cloud infrastructure - including compute, storage, networking, and managed services strategy

Define backend service architecture: microservices decomposition, event-driven systems, API gateway patterns, and service mesh configuration

Lead platform engineering efforts: developer portals, internal tooling, shared libraries, and golden-path templates that accelerate every product team

Design and govern data architecture decisions: databases at scale, caching layers (Redis, CDN) and streaming pipelines

Establish SLO/SLA frameworks, error budget policies, and on-call standards that balance reliability with engineering velocity

Lead digital security architecture: zero-trust network design, identity and access…
