About The Position

Box is on a mission to power how the world works together. Box AI is central to that mission—bringing intelligent assistance and agentic workflows to our customers across web, mobile, and desktop. The AI Experiences team works on the core user experiences that bring Box AI to life across Box products. We’re looking for a Senior Software Engineer to lead the design and delivery of cross-platform AI experiences with speed, quality, and strong technical judgment. You will own or co-own team-level initiatives across web & mobile that ship delightful Box AI user experiences to customers. Your primary focus will be on front-end architecture in React and React Native while partnering closely with backend engineers and cross-functional stakeholders. If you’re passionate about making AI the new user interface for Box content, this role is for you.

Requirements

5+ years of professional software engineering experience with a strong focus on front-end development
Deep expertise in React; React Native is a strong plus, but React alone is sufficient — having both is a significant advantage.
Full-stack understanding — comfortable with backend APIs, system design, and defining interfaces and contracts, enabling collaboration with backend partner teams even as primary focus is frontend.
Actively use AI coding tools — such as Cursor, Claude Code, or Codex — as a core part of your development workflow, including requirements gathering, writing tests, and feature delivery; this is a hard requirement, not a bonus.
Demonstrated track record of shipping significant changes across multiple components or systems with minimal guidance, in fast-paced environments where you shape requirements rather than wait for them.
Collaborative mindset, a commitment to inclusive and accessible design, and a passion for mentoring peers and elevating engineering practices through high-quality code review.

Nice To Haves

Experience with CI/CD pipelines, A/B testing, and feature flag-driven development
Exposure to GCP and cross-platform mobile architecture is a plus.

Responsibilities

Own or co-own the design, implementation, and delivery of Box AI chat and agentic frontend experiences across all of Box's web and mobile applications, spending approximately 80% of your time on frontend development and 20% collaborating with backend engineering teams.
Shape and inform requirements alongside Product Managers and UX Designers — not just implementing specs, but helping define them, making trade-offs quickly, and driving decisions in a fast-paced environment.
Ship weekly to production, contributing daily PRs and making incremental advances toward feature delivery within one-week sprint cycles.
Help define cross-platform best practices for new feature development across web, iOS, and Android, establishing patterns and standards that scale across the team.
Uphold accessibility, performance, and quality standards through thoughtful engineering, code reviews, and testing — spending at least an hour daily on PR reviews to raise the bar for your peers.
Stay current with rapidly evolving AI model capabilities and translate them into meaningful customer value, responding quickly when new models require corresponding frontend experience changes.
Partner with backend engineering teams to define interfaces, contracts, and incremental delivery milestones, ensuring full-stack quality even as your primary focus remains on the frontend.
Participate in our on-call rotation, available at all times while on-call to help respond to and triage any issues that arise.
