Senior Software Engineer (Database)

• VAST Data is looking for a Senior Backend Software Engineer to help build the engine behind the next generation of scalable, AI-native data infrastructure
• In this role, you will focus on the design and development of backend services powering our massively distributed, high-performance combined analytical and vector database, a critical component of VAST’s AI data platform
• This is your opportunity to work at the intersection of low-level systems programming, distributed computing, and AI infrastructure—helping us push the boundaries of backend engineering for real-time, petabyte-scale data systems
• Architect and implement core backend components for a distributed vector database using C/C++
• Design highly scalable distributed data-structures and algorithms optimized for performance, concurrency, and fault tolerance
• Develop backend services that enable fast search, efficient indexing, and real-time analytics over massive datasets
• Optimize system performance across multi-threaded and multi-node environments
• Ensure low-latency, high-throughput data access and manipulation across global deployments
• Collaborate closely with cross-functional teams to translate backend capabilities into real-world impact
