Senior Principal Engineer

// -----No C2C -----// ----Only W2----//

Duration: 6+ months contract

Location: Folsom, CA (Onsite)

Pay Range: $85/hr to $95/hr on w2

Description:

• Enable vector database frameworks such as DiskANN, Milvus, and related retrieval/search pipelines on an FPGA-accelerated platform
• Modify and optimize software stacks so that distance computation and related vector operations can be offloaded to FPGA-based storage or accelerator device Design and integrate host-side software paths to issue custom or vendor-specific NVMe commands for computation offload
• Develop and optimize I/O submission/completion paths using modern Linux interfaces such as io_uring
• Analyze existing VectorDB execution flows and identify where offload can be inserted with minimal software disruption
• Debug full-stack issues spanning application software, libraries, kernel/user-space I/O paths, NVMe protocol behavior, and FPGA device responses.

Requirements:

• Bachelor s or Master s degree in Computer Science, Computer Engineering, Electrical Engineering, or related field
• Strong programming skills in C/C++ and experience with performance-oriented system software development
• Hands-on experience with vector databases, similarity search, or ANN frameworks such as DiskANN, Milvus, FAISS, or related systems.
• Good understanding of Linux systems programming, storage I/O, and asynchronous I/O models
• Familiarity with NVMe protocol, command structure, submission/completion queues, and storage performance concepts.
• Experience analyzing and modifying open source software stacks for performance optimization and platform integration
• Strong debugging and profiling skills across user-space and system-level software.
