Role DescriptionAt Dropbox, our Mobile Infrastructure team plays a critical role in ensuring that our engineers can build, test, and ship world-class mobile experiences with speed and reliability. We are looking for an engineer who can help elevate this foundation and bring our systems to the next level. In this role, you will own and evolve our Bazel build system while driving improvements to our CI/CD pipeline through tools such as Buildkite. You’ll partner closely with other engineers to streamline workflows, resolve bottlenecks, and create scalable solutions that empower teams across Dropbox. With your expertise in Bazel, CI/CD, and iOS development, you’ll not only maintain and optimize our infrastructure but also enable our developers to work more efficiently and effectively. This is a unique opportunity to shape the core systems that power Dropbox mobile development, collaborate with talented cross-functional teams, and directly influence the velocity and quality of how we deliver Dropbox to millions of users worldwide. Our Engineering Career Framework is viewable by anyone outside the company and describes what’s expected for our engineers at each of our career levels. Check out our blog post on this topic and more here. Responsibilities - Maintain and upgrade our current tooling both to support developers as well as ensure a properly functional CI/CD system - Improve the mobile build scripts by working on foundational issues and helping to rearchitect, as necessary - Work with other engineers to promote best practices and ensure a high quality bar is maintained - Collaborate with other build and platform teams to ensure tooling is properly supported and scalable to future solutions - Provide support for other components owned by this team, not limited to features currently written in Swift Many teams at Dropbox run Services with on-call rotations, which entails being available for calls during both core and non-core business hours. If a team has an on-call rotation, all engineers on the team are expected to participate in the rotation as part of their employment. Applicants are encouraged to ask for more details of the rotations to which the applicant is applying. Requirements - Bachelor’s degree in Computer Science or related technical field involving coding (e.g., Physics or Mathematics), or equivalent technical experience - 5-9 years of experience - Understanding of operation/administration CI/CD systems (e.g Buildkite, CircleCI, Jenkins) - Engineering skills and experience with iOS application development with interest in deep-diving into platform build tools (i.e Bazel) - Experience working across teams/org to accomplish long-range projects - Understanding of either/both macOS/Linux system administration is a plus Preferred Qualifications - Proficiency in Swift - Understanding of either/both macOS/Linux system administration Compensation US Zone 1 $204,000—$276,000 USD US Zone 2 $183,600—$248,400 USD US Zone 3 $163,200—$220,800 USD
