Role

We are looking for a seasoned Staff Software Development Engineer (UI/React.js) to join our team in San Jose, CA, reporting to the Director, Engineering in the Unified Experiences Platform department. As a key member of this team, you will be responsible for crafting high-quality libraries and tools while building high-performance, resilient UI that scales. You will serve as a technical leader, driving engineering excellence and ensuring our frontend architecture meets the highest standards of performance and maintainability.

• Identify and resolve technical challenges by incorporating a robust test automation strategy
• Participate in code reviews and enforce coding standards to ensure a maintainable codebase

Who You Are (Success Profile)

• You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful.
• You act like an owner. Your passion for the mission fuels your bias for action. You operate with integrity because you genuinely care about the outcome. True ownership involves leveraging dynamic range: the ability to navigate seamlessly between high-level strategy and hands-on execution.
• You are a problem-solver. You love running towards the challenges because you are laser-focused on finding the solution, knowing that solving the hard problems delivers the biggest impact.
• You are a high-trust collaborator. You are ambitious for the team, not just yourself. You embrace our challenge culture by giving and receiving ongoing feedback-knowing that candor delivered with clarity and respect is the truest form of teamwork and the fastest way to earn trust.
• You are a learner. You have a true growth mindset and are obsessed with your own development, actively seeking feedback to become a better partner and a stronger teammate. You love what you do and you do it with purpose.

What We're Looking for (Minimum Qualifications)

• 5+ years of experience in JavaScript development with a focus on building and deploying ReactJS applications
• Expertise in creating lean, clear documentation, testing, and automation as integral components of the UI workflow
• Exceptional problem-solving skills and a proven ability to develop creative solutions to technical challenges
• Experience effectively conveying complex technical concepts to both technical and non-technical stakeholders
• Demonstrated track record of fostering engineering excellence and driving innovation

What Will Make You Stand Out (Preferred Qualifications)
