Join CBSSports and shape the future of sports media through cutting-edge AI-powered content and deeply personalized fan experiences across mobile, web, and digital platforms. We are seeking a Principal Software Engineer to be a core member of our Solutions Architecture team. In this role, you will be crucial in partnering with product, design, and engineering leadership to design, prototype, and deliver groundbreaking AI solutions at scale.

What You Will Do
●    Lead AI Architecture: Architect and implement advanced Generative AI and Retrieval-Augmented Generation (RAG) systems to power intelligent recommendations and dynamic user personalization.
●    Drive Development: Lead the rapid prototyping and full-cycle development of production-grade features for mobile and web applications.
●    Define Standards: Establish, promote, and drive adoption of scalable platform standards, engineering patterns, and reusable components across the organization.
●    Collaborate and Prototype: Work closely within a small engineering group, partnering with design and product teams to rapidly design, develop, and prototype solutions to key business challenges.
●    Ensure Quality: Define guardrails to ensure fast, secure, and compliant adoption and deployment of "vibe coded" applications. Write robust requirements and production-quality code.
●    Advocate for AI: Utilize AI development tools to optimize your workflow and champion the use of AI-driven development practices across the team.
●    Operational Excellence: Design for scalability and reliability, incorporating appropriate testing, monitoring, and alerting.
●    Mentor and Document: Build clear documentation and diagrams to facilitate easy onboarding for other engineers and support teams. Review code to ensure adherence to best practices (style, testability, efficiency).
●    Front-End Performance & Observability: Own front-end performance (Core Web Vitals, bundle size, caching) and observability (RUM, error tracking) for web and mobile applications.
●    Monorepo Tooling: Establish and evolve monorepo tooling and workflows (e.g., Turborepo, Nx) to support build, test, and deploy across web and mobile applications.
●    Type Safety & Standards: Promote and evolve TypeScript and typing standards (e.g., strict mode, shared types, codegen) so that codebases stay maintainable, type-safe end to end, and refactor-safe.
Required Qualifications
●    Expertise in AI: Proven, production-level expertise in Generative AI and RAG architectures.
●    Platform Experience: Strong track record of building scalable platform products and establishing cross-team engineering standards.
●    Stakeholder Management: Ability to collaborate with and influence senior stakeholders in a dynamic, fast-paced environment.
●    Browser & Performance: Solid understanding of browser behavior, rendering, and front-end performance (e.g., Core Web Vitals, lazy loading, code splitting).
●    Monorepo Experience: Experience with monorepo tooling and workflows (e.g., Turborepo, Nx), including shared packages, task pipelines, and cross-project dependencies.
●    Education & Experience: BS in Computer Science or equivalent experience.
○    10+ years of experience building scalable, production-grade web applications using modern JavaScript frameworks (React, Next.js) and Node.js.
○    Strong expertise in JavaScript and TypeScript, including asynchronous programming, generics, strict typing, and advanced ES6+ features.
○    Deep knowledge of HTML and CSS, including responsive layout, cross-browser compatibility, accessibility, and performance optimization.
○    Experience consuming and designing APIs (REST and GraphQL), including Apollo Client and microservices-based architectures.
○    Proven experience modeling complex data flows for transactional and integration workflows.
○    Experience working with cloud platforms (AWS, GCP, or OCI) and container
