Frontend Product Software Engineer, Web DX

Role Description At Dropbox, we believe in simplifying the way people work together. Our mission is to empower teams to build robust, scalable, and delightful web products with confidence. Web DX team supports this mission by creating and maintaining the build systems and developer tools that make engineering at Dropbox faster, more reliable, and more productive. As a Software Engineer on the Web DX team, you’ll contribute to projects that improve the daily workflows of Dropbox web engineers. You will help build and refine the tools and systems that power tasks such as faster builds, smoother testing, type safety, and scalable internationalization - directly impacting developer productivity and confidence. Within Web DX, the Web Build team focuses on build-time systems and tooling, including Bazel rules, TypeScript and React integrations, i18n pipelines, and JS package management and bundling. In this role, you’ll gain valuable exposure to modern build technologies, collaborate with senior engineers to identify and solve developer pain points, and grow your expertise in scaling developer experience across a large engineering organization. This role is an excellent opportunity to develop platform engineering skills, contribute to high-impact systems used by hundreds of engineers, and learn how to shape web development practices at scale. You’ll be part of a collaborative team that values technical excellence, thoughtful abstractions, and building tools that last. 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 Contribute to the development and maintenance of build systems and developer tools that support Dropbox’s web engineering ecosystem, including Bazel rules, TypeScript tooling, React workflows, and i18n pipelines. Implement improvements that help streamline and standardize the development process, such as adding automated checks, improving abstractions, or extending scaffolding to reduce complexity. Collaborate closely with product engineers to understand workflow challenges and help deliver solutions that improve web build speed, reliability, and consistency. Adopt and apply modern practices in areas like static analysis, code quality enforcement, and incremental builds, working with senior engineers to introduce and maintain best practices. Participate in team initiatives that improve developer productivity at scale, such as optimizing build/test loops, enhancing build pipelines, and improving i18n tooling. On-call work may be necessary occasionally to help address bugs, outages, or other operational issues, with the goal of maintaining a stable and high-quality experience for our customers. Requirements BS in Computer Science or related technical field, or equivalent practical experience. 2+ years of software engineering experience (or strong internship/project experience for recent graduates). Proficiency in JavaScript/TypeScript and familiarity with modern frontend frameworks such as React. Interest or experience in developer tooling, build systems, or productivity engineering (e.g., Bazel, RSPack, esbuild, or similar). Strong problem-solving skills, with the ability to debug and improve developer workflows. Collaborative mindset with a willingness to learn from and work closely with senior engineers. Experience with static analysis, linters, or code quality tools a plus. Preferred Qualifications Experience contributing to or maintaining build systems (e.g., Bazel,) or bundlers (e.g., Webpack, rspack, Rollup). Familiarity with build pipelines and automated testing frameworks. Hands-on experience building or extending developer productivity tools such as linters, formatters, or scaffolding generators. Familiarity with monorepo development and dependency management at scale. Exposure to internationalization (i18n) workflows or localization tooling. Experience improving development workflows and test/build pipelines. Demonstrated ability to identify developer pain points and propose/implement process or tooling improvements.
