About the role

We are looking for a Full Stack Software Dev Engineer II to join our Identity organization.
In this role, you will work independently with minimal guidance, owning critical features and acting as a technical resource for your peers.
We seek engineers who possess an experimentation-forward mindset and view AI as a force multiplier for architectural excellence and team-wide productivity.

Responsibilities

Design, build, and operate secure, scalable full-stack identity systems using ReactJS, TypeScript, Java, and Node.js.
Own complex features and standalone project phases end-to-end, from gathering requirements and systems design to implementation, testing, and production.
Lead an AI-first development workflow within the squad, writing precise markdown specifications to drive AI-assisted code generation (Cursor, Claude Code), and taking responsibility for the rigorous validation, testing, and safety of all generated assets.
Proactively research and implement AI-driven efficiencies in your daily coding workflows, replacing repetitive manual tasks with structured automation, custom templates, and AI-assisted testing.
Collaborate cross-functionally with Product Managers, UX Designers, Security Engineers, and other Yahoo product squads to coordinate technical integrations.
It takes powerful technology to connect our brands and partners with an audience of hundreds of millions of people.
Whether you're looking to write mobile app code, engineer the servers behind our massive ad tech stacks, or develop algorithms to help us process trillions of data points a day, what you do here will have a huge impact on our business-and the world.
You will work across the stack to build secure, scalable, and user-friendly authentication and account management experiences that serve hundreds of millions of users globally.

Bachelor's degree in Computer Science, a related technical field, or equivalent practical experience.
4-6 years of professional full-stack software engineering experience.
Strong hands-on engineering experience using Java for robust backend services.
Proven capability to evaluate, audit, and debug AI-generated outputs, ensuring alignment with Yahoo's high standards for code quality, security protocols, and performance.
Experience with testing frameworks, CI/CD pipelines, and writing production-ready, highly maintainable tests.

Nice to have

Cloud platform experience (GCP, AWS, or Azure) and infrastructure-as-code.
Familiarity with observability tools (Splunk, Grafana) and client/server performance profiling.
Experience with structured development methodologies, such as Spec-Driven Development (SDD), API-first design, or AI-assisted diagnostic tools.
Exposure to web accessibility (WCAG), internationalization, or large-scale consumer product delivery.
What Success Looks Like
Raise overall engineering standards by contributing to system architecture discussions, documenting clear technical specifications, and mentoring junior engineers.
Accelerate squad velocity by sharing innovative, repeatable ways to integrate AI workflows into daily development, testing, and troubleshooting activities.
The material job duties and responsibilities of this role include those listed above as well as adhering to Yahoo policies
