Senior Software Engineer

Who we are

The MongoDB Atlas team is a diverse group of engineers working together to help developers manage MongoDB at a global scale. We are responsible for MongoDB Atlas; our database-as-a-service and fastest-growing product, which enables users to deploy fault-tolerant, globally distributed clusters in minutes.

Within Atlas, the Frontend Platform team is focused on modernizing the Atlas UI stack. Our mission is to provide developers with the tools, frameworks, and build systems they need to create fast, reliable, and user-friendly UI features. From global navigation and dark mode to testing frameworks and build pipelines, we ensure the Atlas frontend is performant, scalable, and delightful for our customers.

We are seeking a Senior Software Engineer (Frontend) to join our Frontend Platform team. In this role, you’ll work on both customer-facing UI features and developer productivity tools that power Atlas at scale. You’ll collaborate with engineers across teams, contribute to complex projects, and help shape the future of our frontend ecosystem.

We are looking to speak to candidates who are based in Dublin for our hybrid working model.

What you’ll do

• Design, architect, and deliver customer-facing features for the Atlas UI
• Develop and maintain unit, integration, and end-to-end testing frameworks
• Optimize build pipelines, including asset bundling for the browser
• Improve code quality using static analysis, linting, type-checking, and best practices
• Collaborate and mentor, supporting engineers within UI/UX development across multiple teams
• Lead and contribute to high-impact, cross-functional projects and initiatives

What we look for

• 5+ years of frontend development experience, or equivalent practical experience
• Proficiency in JavaScript/TypeScript and modern frontend frameworks (React, Redux); Knowledge of a modern compiled language (Java, Go, C#, C++) is a plus
• Strong ability to communicate with both technical and non-technical stakeholders; passion for teamwork and mentoring
• Curious, empathetic, collaborative, and motivated to learn new technologies
• Experience with frontend build systems (Webpack, ESLint, TypeScript) and testing frameworks (Jest, Cypress, React Testing Library)
• Interest in Bazel or similar build tooling is a plus

Success Measures

• 1 Week: Submit your first pull request
• 3 Months: Contribute to a large-scale project and gain a surface-level understanding of our domain (React, TypeScript, CI testing, linting, monitoring, Bazel)
• 6 Months: Lead the design and execution of your own project, with deeper expertise across the domain
