Frontend Software Engineer II

Title: Frontend Software Engineer II

Location: US - United States of America

Job Description:

Yahoo serves as a trusted guide for hundreds of millions of people globally, helping them achieve their goals online through our portfolio of iconic products. For advertisers, Yahoo Advertising offers omnichannel solutions and powerful data to engage with our brands and deliver results.

A Little About Us

The Media Platform team supports all Yahoo verticals in developing and delivering the best products to our customers globally with the highest standards. The Media Platform team is focused on enabling the company to build world-class products by creating and supporting services leveraged by multiple verticals. Our team operates with tenets that emphasize building a modern competitive platform regarding service, cost, and capabilities, ensuring services can be self-served, and supporting multiple verticals. 

A Lot About You

We are looking for a skilled and motivated Software Engineer II to join the Media Platforms team. We build the shared services, infrastructure, and experiences that power content delivery across Yahoo's product portfolio. You'll work across the stack — with a focus on the frontend — to build, ship, and operate the services and interfaces that bring these experiences to life.

This role is ideal for someone with a strong foundation in modern React development and full stack sensibilities — someone comfortable working in backend services, cloud infrastructure, and APIs, not just the UI layer. You'll work closely with backend engineers, designers, and product managers to deliver features that directly impact millions of users.

We're looking for someone who is highly engaged, drives technical discussions forward, and contributes to the team's technical direction. The ideal candidate takes initiative and is comfortable shaping solutions in a fast-moving environment where the product is actively evolving. We don't expect you to have experience with every tool listed; curiosity and a willingness to learn go a long way. We value engineers who take pride in clean design, ask good questions, and lift up the team — not just the code. We support engineers who use AI-assisted tools as part of their day-to-day workflow — whether for coding, prototyping, debugging, or learning — and we share what's working across the team.

Responsibilities

• Design, build, and maintain performant frontend components and pages using React and Next.js within a server-rendered architecture.

• Develop and integrate with GraphQL APIs via Apollo Client to fetch and render content experiences.

• Build and maintain backend services and APIs that support the frontend, working across the full stack as needed.

• Implement reusable, accessible UI components aligned with the Yahoo Universal Design System (UDS) and modern design standards.

• Write clean, testable, and reliable code, deploying continuously to large-scale, globally distributed production systems.

• Write comprehensive tests using Vitest, React Testing Library, and Playwright to ensure quality and prevent regressions.

• Collaborate with backend engineers to define and evolve the GraphQL schema and data contracts that power the frontend experience.

• Optimize frontend performance including bundle size, rendering speed, lazy loading, and caching strategies for high-traffic pages.

• Take end-to-end ownership of key features and product areas, from implementation through deployment, monitoring, and operational reliability.

• Use AI-assisted development tools thoughtfully to accelerate routine work, explore unfamiliar code, and stay focused on the hard problems that need human judgment.

• Support CI/CD pipelines using GitHub Actions, ensuring reliable and repeatable deployments.

• Participate in code reviews to foster a culture of collaboration, knowledge sharing, and technical excellence.

• Work cross-functionally with product, design, and data teams to translate requirements into polished, user-facing features.

• Actively contribute to technical discussions, clarify open questions, and help shape implementation approaches alongside senior engineers.

Qualifications

• Experience building applications with Next.js or similar React meta-frameworks (server-side rendering, static generation, API routes).

• Hands-on experience consuming GraphQL APIs using Apollo Client or similar libraries.

• Solid understanding of HTML5, CSS3, and responsive/accessible design principles (WCAG).

• Experience with modern testing frameworks (Vitest, Jest, React Testing Library, Playwright, or Cypress).

• Experience with Git-based workflows, code review practices, and CI/CD pipelines (GitHub Actions or similar).

• Comfort working with AI-assisted development tools (code assistants, agentic dev environments, etc.) as part of a modern engineering workflow.

• Proficiency with documentation tools and design collaboration platforms such as Figma.

• Strong foundation in computer science fundamentals, including data structures, algorithms, and software design principles.

• Self-directed and resourceful, with a track record of taking initiative and moving work forward independently.

Preferred Skills & Experience

• Experience with backend development (Node.js, Go, Java, or Python) and building or maintaining APIs.

• Familiarity with cloud service providers (AWS, GCP) and cloud-native architectures.

• Familiarity with component library development and documentation tools such as Storybook.

• Hands-on experience with Apollo GraphQL Server or GraphQL Federation.

• Proven track record in web performance optimization, application stability, and debugging for large-scale applications.

• Interest in AI-driven product experiences and how engineering can enable personalization at scale.

Bonus Skills & Qualifications

• Experience with infrastructure-as-code tools (Terraform) for cloud resource provisioning.

• Experience with native mobile app development (React Native, Swift, or Kotlin) and mobile GraphQL clients (Apollo iOS, Apollo Kotlin).

• Experience integrating with design systems or contributing to shared component libraries.

• Exposure to observability and monitoring tools (Splunk, Datadog, Grafana, Chronosphere).
