Distributed Systems Engineer – Vector Database (Prototype)

About the Role

HI Technology & Innovation is collaborating with a pioneering database company to evolve a single-threaded, command-line vector database proof-of-concept, originally written in C#, into a demonstrable, parallelized prototype. We’re looking for an experienced Distributed or Parallel Processing Engineer to lead the development of a lightweight “controller + wrapper” layer that adds multi-instance orchestration, parallelism, and query merging capabilities to the current system.

This is a high-impact, fast-paced role ideal for someone with strong distributed systems thinking and a pragmatic, get-it-done engineering mindset.

What You’ll Tackle

• Design and implement a wrapper / controller layer around the existing single-threaded vector DB POC.
• Enable sharding and parallel loading of large vector datasets across multiple instances.
• Implement logic to dispatch and coordinate parallel queries , aggregate candidate vectors, apply a pluggable distance metric (e.g., Euclidean, cosine similarity, SAD / Manhattan), and merge and sort results before returning to the caller.
• Expose both command-line and REST interfaces to interact with the system.
• Output clear timing metrics to demonstrate speed-ups from parallel execution.
• Deliver a working, testable prototype —production-ready polish is not required.
