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 Storage Team is building WiredTiger, a world-class distributed open-source storage engine. WiredTiger employs modern hardware architectures and innovative software algorithms to achieve extraordinary performance for the most demanding applications. This team includes database engineering pioneers with decades of experience who are considered deep domain specialists. Due to growth, we are looking for a results-oriented individual to join our outstanding team in Sydney.
This group provides efficient data storage and scalable parallel access that is leveraged by the higher layers of the MongoDB data platform stack. We are a diverse collection of individuals - having different backgrounds, levels of domain knowledge, viewpoints and experiences - all working together to keep MongoDB storage ahead of the most challenging customer expectations.
Our projects include supporting efficient sparse data via column stores, algorithm improvements and performance optimisations, enabling additional workloads at the higher levels of MongoDB and working with our Server teams to unlock innovative and exciting new features.
If you want to join a globally distributed, inquisitive, hand-picked team of engineers who take on the challenges of a fast growing and ever demanding data storage technology, join us!
We are looking to speak to candidates who are based in Sydney for our hybrid working model.
