Company mission
To empower intelligent agents to store, think, communicate, and act.
Role
Who you are
- Strong experience in systems programming, preferably C/C++
- Deep understanding of database internals (e.g., query planners, storage engines, transaction processing)
- Expertise in fundamental computer science concepts like data structures, algorithms, and operating systems
- Proven experience building or contributing to complex, high-performance systems such as databases, file systems, or distributed data platforms
- Note: Experience limited to writing SQL queries or database administration is not a fit for this position. We are seeking engineers with experience in the core engineering of a database system
What the job involves
- VAST Data is looking for a Core Database Developer (Database Internals) to join our growing team!
- This is a great opportunity to be part of one of the fastest-growing infrastructure companies in history, an organization at the center of the revolution in artificial intelligence, which is creating a hurricane of change
- We are looking for a talented Software Engineer to design, build, and optimize the core engine of our high-performance database system. This is a deep, systems-level role focused on the internal workings of a database. You will be responsible for creating the fundamental components that store, retrieve, and process data efficiently
- Design & Develop Database Components: Implement and enhance core database features, including the storage engine, query execution engine, and transaction manager
- Optimize Performance: Work on low-level data structures (like B-Trees or LSM-Trees), concurrency control mechanisms (MVCC), and query optimization algorithms to improve speed and efficiency
- Build the Query Engine: Develop the system that parses, plans, and executes user queries against our data structures
- Ensure Reliability: Implement mechanisms for data recovery, consistency, and durability
Our take
VAST Data is building what you might call the plumbing for the AI era - a purpose-built data platform that unifies storage, compute, and data services in a single, scalable system. With its disaggregated, shared-everything (DASE) architecture, it allows companies to scale their storage independently from compute, meaning AI workloads can grow without behind held back by infrastructure bottlenecks. And their platform delivers flash-speed performance, multi-protocol access, and enterprsie-grade reliability, all while keeping costs reasonable.
This architecture is especially relevant now and the company has recently partnered with GMI CLoud as a key data infrastructure provider for GMI's ambitious new "AI factory" in Taiwan. The data centre is expected to house 7,000 NVIDIA Blackwell GPUS and will lean on VAST's exabyte-scale storage to handle data for model training, inference, and real-time processing.
On top of this, VAST has secured some major partnerships and deals that really position it strongly for the future of AI infrastructure. In November 2025, it struck a $1.17B agreement with CoreWeave, making VASt the primary data foundation for their GPU cloud. It also expanded its collaboration with Google CLoud to offer its AI Operating System as a fully managed service, allowsing global data access across on-prem and cloud environments using VAST DataSpace. These moves suggest VAST isn't just keeping up with AI demand but shaping the infrastructure that will power the next generation of large-scale, distributed intelligent systems.
