Job Description

Aligned with Microsoft’s mission to empower every person and every organization on the planet to achieve more, Microsoft Shopping delights customers with confidence, convenience, and savings—anywhere. With the power of AI, we’re building best-in-class shopping experiences that span across Copilot, Edge, Bing, MSN, and Windows, helping customers discover, evaluate, and decide with speed and trust. We’re looking for a Senior Software Engineer (Frontend/Full Stack) to help shape the future of AI-powered shopping in Copilot. This role is “full stack” in the truest sense—you’ll collaborate across design, product, and engineering to deliver end-to-end experiences—but the center of gravity is the front end: building modern, convenient user interfaces that feel fast, polished, and reliable at massive scale.

Job Responsibility

  • Build and ship Copilot Shopping experiences end-to-end, with a solid emphasis on frontend quality (UX polish, accessibility, performance, reliability)
  • Work fluidly across the full architecture: client (web/mobile), services/APIs, data contracts, telemetry/experimentation, and operational tooling
  • Partner closely with Product, Design, and Data Science to define success metrics, instrument telemetry, run experiments, and iterate based on outcomes
  • Design and implement reusable UI components and client patterns, while also contributing to service integration and backend changes when needed to unblock or improve the experience
  • Drive engineering excellence via code reviews, automated testing, CI/CD hygiene, performance profiling, and solid live-site ownership (monitoring, alerting, incident response)
  • Debug and resolve complex issues that span client - service - data/telemetry, improving observability and reducing time-to-diagnosis
  • Make pragmatic architecture decisions that increase modularity, maintainability, scalability, and developer velocity
  • Mentor and elevate the team through technical leadership, documentation, and best practices

Requirements

  • Bachelor's Degree in Computer Science or related technical field AND 4+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python
  • OR equivalent experience
  • Meaningful frontend and full-stack ownership delivering polished, performant user experiences across web and/or mobile surfaces (Kotlin/Swift/web)
  • Microsoft Cloud Background Check: This position will be required to pass the Microsoft Cloud background check upon hire/transfer and every two years thereafter

Nice to have

  • Master's Degree in Computer Science or related technical field AND 6+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python
  • OR Bachelor's Degree in Computer Science or related technical field AND 8+ years technical engineering experience
  • OR equivalent experience
  • Experience integrating clients with backend systems via client–server contracts (e.g., REST/JSON, GraphQL, SSE/WebSockets) and collaborating on API/data contract design
  • Demonstrated ability to debug and troubleshoot client issues and drive performance optimizations for high quality user experiences
  • Experience building accessible applications that follow WCAG and ADA specifications
  • Strong collaboration skills and data-driven execution: work effectively with engineers, PM, design, and partner teams
  • instrument telemetry and use data to iterate
