Overview

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.

You should be deeply fluent in at least one of our primary client stacks—Web (e.g., React), Kotlin, or Swift—and excited about moving across surfaces as the product demands. Some weeks that might mean shipping a high-impact UI iteration on web; other weeks it might mean partnering on a mobile surface, tightening API contracts, or improving performance and telemetry to ensure we can measure what matters. We want an engineer who can jump in, learn quickly, and ship—someone who thinks like an owner, sweats the details, and can connect customer experience to engineering fundamentals.

If you’re passionate about building delightful consumer experiences, iterating quickly with data and experimentation, and operating at the intersection of AI and shopping, this is a chance to work on a fast-moving product with real visibility and impact—while being part of a team that values clarity, craftsmanship, and collaborative execution.

This expectation is subject to local law and may vary by jurisdiction.

Responsibilities

• 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.

Qualifications

Required Qualifications:

• 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).

Other Requirements:

• Microsoft Cloud Background Check: This position will be required to pass the Microsoft Cloud background check upon hire/transfer and every two years thereafter.

Preferred Qualifications:

• 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 with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python
  • 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.
