Job Description

Who we are

We're Redis. We built the product that runs the fast apps our world runs on. (If you checked the weather, used your credit card, or looked at your flight status online today, you’re welcome.) At Redis, you’ll work with the fastest, simplest technology in the business—whether you’re building it, telling its story, or selling it to our 10,000+ worldwide customers. We’re creating a faster world with simpler experiences. You in?

This is a unique opportunity to shape Redis capabilities to the AI era early in the cycle.

You will Join the core Redis Search/Vector team to solve AI’s hottest problems including state-of-the-art indexing, vector/hybrid retrieval, and latency-critical serving at global scale. You’ll take features from research to production, improving latency, recall, and cost for millions of developers worldwide.

What you’ll do:

Design, implement and optimize core vector and information-retrieval algorithms (e.g., HNSW, Quantization, re-ranking).
Solve complex real-world problems at Internet scale, with a strong focus on performance and reliability
Implement hardware-specific optimizations (e.g.: SIMD, SSD, GPU, CUDA)
Collaborate closely with Redis Core, Cloud, and Support teams
Lead designs, mentor peers, set benchmarks, and build a reputation internally and in the community

What will you need to have?

Senior level production-grade system experience (typically 7+ years) building databases, search engines, or high-perf distributed/storage systems
Solid background in either vector/IR search or systems (storage or distributed), with depth in at least one
Proficiency in C/C++ or Rust, including concurrency, memory safety, and performance optimizations
Ability to think strategically, define the technical design and work breakdown, and influence architectural decisions
Bachelor’s or Master’s degree in Computer Science or equivalent practical experience

Extra great if you have:

Familiarity with NoSQL databases, especially Redis, and their practical applications
Experience contributing to or maintaining open-source projects
Background in high-performance multithreaded systems
Experience with distributed systems in production environments

We give back to our employees:

Our culture is what makes Redis a fun and rewarding place to work. To support you at work and beyond, we offer all our team members fantastic benefits and perks:
