Join to apply for the Senior Software Engineer role at VAST Data . 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, at the center of the revolution in artificial intelligence and the creation of a hurricane of change. Key Responsibilities Design and develop core database components: implement and enhance the storage engine, query execution engine, and transaction manager. Optimize performance: work on low‑level data structures (B‑Trees, LSM‑Trees), concurrency control (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 (query planners, storage engines, transaction processing). Expertise in fundamental computer science concepts such as 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. Experience limited to writing SQL queries or database administration is not a fit for this position.
