Now, we need you to be a key part of our next chapter - enabling the Mail engineering organization with AI-powered tools, frameworks, and services that enhance developer effectiveness, quality, and velocity across web, mobile, backend, and generative interfaces. You will enable a high-performance SDLC, empowering engineers to build high-quality products at scale. A lot about YOU You have a strong focus on next-generation AI-powered development—comfortable not only with AI-augmented coding but with creating sharable skills, pipelines, and autonomous agents that power all parts of the modern SDLC. You are a developer at heart, but you highly value improving the engineering experience itself, helping peers focus on delivering complex user experiences while minimizing overhead and manual toil. You are intimately familiar with systems across the development stack, including CI/CD systems, cloud platforms, and generative developer tooling. You prioritize driving tasks to completion, collaborating across squads to achieve high-performance results, thinking through architectural edge cases, and teaching through technical leadership. If you are interested in joining a world-class team of highly collaborative engineering professionals who care about making developer lives highly productive, then we’d like to talk to you. Responsibilities: Architect, build, and optimize developer productivity tools leveraging multiple AI tools (e.g. Claude, Cursor, Vertex AI) to provide contextual code suggestions, automated testing, and smart documentation. Identify and implement AI-driven efficiencies in the developer inner-loop, transitioning manual SDLC processes into intelligent, agentic workflows. Establish automated review systems and validation frameworks to verify, clean, and monitor the quality of AI-generated software architectures and outputs. Define, track, and analyze key developer experience (DevEx) metrics to isolate friction points and systematically improve engineering velocity. Take independent ownership of major phases of the SDLC and platform environments, directly impacting the day-to-day workflow of hundreds of Yahoo Mail engineers. Collaborate with engineering leads and cross-functional teams to design, prototype, and implement elegant solutions for complex developer pain points. Solve complex and multifaceted software problems with guidance only in highly complex, ambiguous situations. Act as a technical role model and mentor for peers, executing high-quality code reviews and promoting platform engineering best practices. Lead design discussions, share systemic engineering insights, and build a culture of continuous learning and AI-assisted innovation.

Strong core computer science fundamentals, including advanced competencies in data structures, algorithms, and modular software design. Proficiency in at least one modern programming language such as Java, Python, or Golang. Hands-on experience integrating AI coding assistants, code generation tools, or specialized LLM agents into active development pipelines to accelerate debugging, architectural design, and code refactoring. Experience building robust internal tools for engineering organizations, including scalable backend microservices, unified CLIs, and intuitive web interfaces. Deep understanding of modern software development practices, design patterns, continuous integration (CI), and deployment architecture. Excellent communication and collaboration skills, with a proven ability to lead small project teams or distinct workstreams across geographically distributed teams. Strong technical empathy for developers and a commitment to eliminating roadblocks, delays, and friction in the software development lifecycle. Preferred Qualifications: Experience deploying, fine-tuning, or engineering structured prompts for foundation models within enterprise cloud environments like Google Vertex AI. Experience with CI/CD tools and systems tools such as GitHub Actions, ArgoCD, or Jenkins. Solid experience managing large-scale cloud infrastructure using Infrastructure-as-Code (IaC), with a focus on GCP. Strong familiarity with Unix/Linux development and deployment environments.
