Founding Engineer at SciPhi

At SciPhi, we're on a mission to build R2R, the most advanced AI retrieval system on the planet. We're looking for an exceptional engineer to help us expand its capabilities to handle billions of vectors, power thousands of concurrent AI requests, and meet the needs of global enterprises seeking state-of-the-art retrieval solutions.

What You'll Build

• High-Throughput Database Architectures Design and implement scalable systems using Postgres and PGVector to efficiently manage massive vector operations.
• High-Concurrency AI Pipelines Architect infrastructure that seamlessly handles thousands of concurrent requests for AI-driven workflows, ensuring consistent performance even at peak load.
• Robust, Fault-Tolerant Systems Build reliable frameworks that gracefully manage the complexity of generative AI workloads—where resilience and uptime are paramount.
• Foundational Technology As part of our founding team, you'll have the autonomy to shape core infrastructure decisions and lay the groundwork for future engineers to build upon.

What We're Looking For

• Top-Tier Systems Design Expertise Deep experience with distributed systems, networking, and the art of optimizing database performance at scale.
• Containerization & Cloud Mastery Strong proficiency in Docker, Kubernetes, and modern cloud environments to deploy, monitor, and scale AI infrastructure globally.
• Proven Record of Scaling & Performance Demonstrated ability to push databases and systems to their limits—experience with high concurrency, complex query optimization, and near real-time data processing.
• Passion for AI Infrastructure Familiarity with vector databases and a drive to solve cutting-edge technical challenges in AI. Previous research or advanced competition experience in machine learning or related fields is a huge plus.
• Extraordinary Intellectual Achievements IOI/ACM-ICPC medals, top placements in elite competitions, or groundbreaking scientific publications. We firmly believe such accolades often reflect the insight, creativity, and dedication we prize on our team.
