Infrastructure Software Engineer, Metadata Core

<h3>Role Description</h3> <p>As a Software Engineer on the Metadata team, you’ll build and operate the large-scale distributed databases that every Dropbox service depends on. Metadata systems are mission-critical, in the live path for all user operations and must meet stringent requirements for latency, durability, and transactional consistency.</p> <p>You’ll design and evolve the core infrastructure that manages Dropbox’s databases at scale, enabling fast, reliable access to data for millions of users and hundreds of internal services. This work spans distributed systems, replication, caching, and transactional database systems.</p> <p>You’ll collaborate closely with engineers across Infrastructure and Product teams to ensure the metadata layer meets business needs and continues to scale with Dropbox’s growth. This is an opportunity to leverage your expertise in distributed systems and grow into broader technical leadership.</p> <p>Our Engineering Career Framework is <a href="https://dropbox.github.io/dbx-career-framework/" rel="nofollow ugc noopener" target="_blank"><u>viewable by anyone outside the company</u></a> and describes what’s expected for our engineers at each of our career levels.
