Core Database Developer (Database Internals)

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 that is at the center of the hurricane being created by the revolution in artificial intelligence.

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 internals of how a database works. You will be responsible for creating the fundamental components that store, retrieve, and process data efficiently.

Requirements:

Key Responsibilities

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.

Qualifications

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.
