## About the Role

* Senior-Level Production Experience: 5+ years of shipping production-grade software. You have deep, hands-on authority across modern web architectures (Next.js and React) and backend environments (Node.js and TypeScript). You also have strong experience with RESTful APIs and content management platforms.
 * Web Performance & Architecture Mastery: Advanced expertise in Next.js, server-side rendering (SSR), and modern caching patterns. You demonstrate deep knowledge of Core Web Vitals optimization to deliver lightning-fast experiences for a massive global readership.
 * Quality as a Feature: A fundamental commitment to software quality. You implement rigorous automated testing across unit, integration, and end-to-end suites with Playwright and Maestro. Testing is an inherent part of your development process, not an afterthought.
 * Pragmatic Craftsmanship: A strong bias toward action and simplicity. You thrive in a collaborative environment. You can take existing systems, eliminate technical friction, and make codebases enjoyable and sustainable to scale.
 * End-to-End DevSecOps Mindset: Practical experience managing CI/CD pipelines and embedding security best practices. You have hands-on experience integrating secure identity systems like Auth0 across client and server boundaries.
 * Collaborative Problem Solving: Strong communication skills and comfort working directly with non-engineering stakeholders. You excel at translating product vision into clean, maintainable technical execution.

Nice to Haves:

 * Cross-Platform Mobile Engineering: Hands-on experience building or maintaining mobile apps using React Native and Expo.
 * Publishing & Headless Architecture: Experience with modern headless CMS platforms, such as Sanity, and structured content workflows at scale.
 * Monetization & Analytics Infrastructure: Prior work integrating ad management engines (Google Ad Manager), digital paywalls and billing (Stripe), and behavioral analytics (Amplitude and HubSpot).
 * Cloud Infrastructure & IaC: Familiarity with Google Cloud Platform, including GCP Cloud Functions, and Infrastructure as Code using Terraform.
 * Modern Runtimes & High-Performance Microservices: Curiosity or hands-on experience with emerging web runtimes like Bun and Elysia, as well as in-memory datastores like Redis.

## Description

* End-to-End Delivery Excellence: Own features across the complete product lifecycle. You will lead scoping alongside product and design, oversee shipping, and monitor systems in production. You will ensure systems remain secure, fault-tolerant, and performant.
 * Full-Stack Execution: Architect and ship robust functionality across our web platform, mobile applications, and services layer. You will build high-quality solutions using Next.js, React 19, TypeScript, and modern runtime services.
 * AI-Native Engineering: Leverage AI tools as a default part of how you design, build, and optimize software. We use Claude Code, Open Code, and open-source models daily. You will also identify opportunities to build internal tooling that streamlines workflows for editors, designers, and product partners.
 * Direct Cross-Functional Collaboration: Partner directly with product managers, UX designers, and editorial stakeholders in a nimble team setting. You will take initiatives from rough conceptual drafts to production reality without unnecessary organizational overhead.
 * Safe Release & Operational Governance: Champion progressive rollout practices using feature flags such as LaunchDarkly. Implement automated CI/CD pipelines and disciplined observability. You will deploy frequently with confidence and minimal blast radius.
