Overview
We are seeking a Senior Software Engineer – Frontend Platform & Commerce Experiences to design and build the next generation of reusable, high-performance web components that power Microsoft’s commerce experiences — including pricing, cart, checkout, and payments. This role is for a frontend-focused engineer with experience in modern web frameworks, accessibility, and design systems. You will help define and evolve Microsoft’s commerce UI architecture while ensuring secure, high-quality, and scalable user experiences in close collaboration with design, product, and engineering partners.

Beyond hands-on development, you’ll influence architecture, improve developer efficiency through shared tooling and governance, and ensure quality at scale by reviewing pull requests and mentoring vendor engineering teams.
Microsoft’s mission is to empower every person and every organization on the planet to achieve more. We value respect, integrity, and accountability and foster a culture of inclusion where everyone can thrive. In alignment with our values, this role emphasizes partnership, innovation, and continuous learning.
