MongoDB’s mission is to empower innovators to create, transform, and disrupt industries by unleashing the power of software and data. We enable organizations of all sizes to easily build, scale, and run modern applications by helping them modernize legacy workloads, embrace innovation, and unleash AI. Our industry-leading developer data platform, MongoDB Atlas, is the only globally distributed, multi-cloud database and is available in more than 115 regions across AWS, Google Cloud, and Microsoft Azure. Atlas allows customers to build and run applications anywhere—on premises, or across cloud providers. With offices worldwide and over 175,000 new developers signing up to use MongoDB every month, it’s no wonder that leading organizations, like Samsung and Toyota, trust MongoDB to build next-generation, AI-powered applications.
The Atlas API Experience (APIx) teams are part of MongoDB Atlas Data Services, a diverse group of individuals who develop the capabilities to run MongoDB globally (see MongoDB Atlas). Our software and services allow users to deploy fault-tolerant, scalable, globally distributed MongoDB clusters in minutes. APIx’s mission is to craft delightful experiences for developers of all levels onboarding and working with MongoDB.
We're looking for a Software Engineer to join our growing team, which builds the foundational platform for all of Atlas's public APIs, mainly the Atlas Administration API. As part of this team, you will design, build, and support the core services that define the entire API lifecycle, ensuring a world-class experience for both API consumers and internal developers. You will own the key pillars of our API platform, such as:
- Defining API standards, linting, versioning, breaking change detection, and changelog capabilities
- Implementing API rate limiting and collecting crucial API telemetry
- Improving CI/CD support for API producers, automating example generation, and enhancing our documentation platform through Open API
Furthermore, you will leverage AI to enhance our developer support by refining our central Retrieval-Augmented Generation (RAG) tooling, providing intelligent, context-aware assistance to API Producers. Your work will directly impact how all developers interact with Atlas, both internally and externally, ensuring our APIs are consistent, reliable, easy to use, and form a solid programmatic interface for Infrastructure as Code (IaC) tools, such as the MongoDB Atlas Terraform Provider and AWS CloudFormation.
We are looking to speak to candidates who are based in Dublin for our hybrid working model.
What will you do?
- Design, implement, test, and release features for our Atlas Administration API
- Apply our core values to your work in planning, designing, and delivering
- Build tools that support MongoDB users and developers on their journey
- Incrementally ship elements of sophisticated projects
- Assist with investigating and solving problems experienced by our customers (second-level support for features our team owns)
