Software Engineer 3, Storage Engines

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.

Candidate Profile

• You have strong computer science knowledge and at least 2 years of server-side C or C++ development experience. Professional or advanced academic expertise in the domains of distributed systems and databases is preferable, but not strongly required

• You are willing, able, and motivated to quickly learn new things. You are not afraid to admit you don’t know something or to ask for help


• You are curious about how people and organisations use MongoDB, and how MongoDB could be improved to enable more use cases

Position Expectations

• Understand and improve the current functionality of WiredTiger


• Identify, design, implement, test, and support new features in MongoDB


• Work with other engineers to coordinate seamless changes in a feature-rich, large codebase


• Estimate task complexity and report progress and risks to peers and managers


• Fix code defects and work with support to diagnose and remediate customer issues


• Adapt and adhere to the team norms and the company core values

Success Measures

• In the first month, you will understand the high-level architecture of WiredTiger


• In three months, you will tackle code review responsibilities and will diagnose and fix a few customer or testing-reported issues


• In six months, you will contribute to the development of a project slated for the next major release of MongoDB and participate in the design review for new features


• In twelve months, you are leading the development of a new feature and are helping to mentor new engineers on the team
