Staff Engineer, Apix

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 ).
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 Staff Engineer to lead the design and evolution of our API platform, which is central to how our enterprise customers and internal teams interact with our core database technologies.
This platform underpins mission-critical developer workflows, enables automation via declarative tools like Terraform, and ensures API standards across our ecosystem.
You'll work at the intersection of platform architecture, developer experience, and API governance.
As a technical leader on the team, you'll set the direction for how we build, version, secure, and evolve our APIs, ensuring they are standards-compliant, reliable, and easy to consume.
We are seeking passionate, intrinsically motivated software engineers who consistently strive to grow their skills and aspire to take their careers to the next level.
