At Dropbox, we believe in simplifying the way people work together. Our engineers build the technology that powers seamless collaboration for hundreds of millions of users worldwide. As a Staff Engineer focused on Dropbox Sync, you will play a pivotal role in shaping the reliability, scalability, and future direction of one of Dropbox’s most critical systems.

You will partner with Product Managers, Engineering Managers, and other senior technical leaders to deliver platform improvements that directly impact customers and enable future innovation. You’ll balance short-term execution with long-term architectural investments, ensuring Dropbox’s sync experience continues to set the standard for simplicity and trust.

As a Staff Engineer, you’ll thrive if you love tackling ambiguity, operating with autonomy, and driving technical strategy across teams.

  • Influence org-wide engineering standards by advocating for high-quality systems design, operational excellence, and pragmatic decision-making.
  • Contribute to culture by participating in hiring, onboarding, and company-wide technical forums.

  • BS in Computer Science or related technical field involving coding (e.g., mathematics, physics), or equivalent technical experience.
  • Demonstrated ability to design and ship technically complex products used at scale.
  • Deep expertise in at least one systems-level area (e.g., sync, distributed systems, OS internals, file systems).
  • Strong communication and collaboration skills, with experience influencing across multiple teams and functions.
  • Comfortable balancing short-term delivery with long-term strategic investments.
  • Willingness to participate in on-call rotations where required.
