Job Description

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.

Job Responsibility

  • 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

Requirements

  • 5+ years of experience in backend engineering, with strong proficiency in low-level C and C++
  • Hands-on experience designing and building distributed backend systems or infrastructure at scale
  • Experience with distributed data-structures, algorithms and system reliability patterns
  • Expertise in multi-threaded programming, memory management, and performance tuning
  • Proven track record of backend work on high-throughput databases, vector stores, or real-time processing engines
  • Bachelor’s degree in Computer Science, Engineering, or equivalent experience

Nice to have

  • Experience building or optimizing analytical or vector databases
  • Familiarity with query engine internals, indexing techniques, or storage layer optimizations
  • Knowledge of Python or Java for integration or tooling
  • Bachelor's, Master’s or PhD in a related technical field (distributed systems, backend architecture, database internals)
