Senior Software Engineer - Search Runtime

We are looking for a Senior Software Engineer to work on the runtime systems of a novel search engine tailored for agentic AI consumption. In this role, you will focus on building low-latency, high-throughput systems that serve search queries in real time. You will work on the critical path of user-facing requests, where performance, predictability, and efficiency directly impact product quality. You will design and operate systems that handle thousands of requests per second under strict latency budgets, optimizing every layer from request handling to data access and response assembly.

Have 5+ years of experience building production backend systems

Have strong expertise in C++ or Rust

Have experience with high-load, low-latency user-facing systems

Have worked on systems handling thousands of RPS under strict latency constraints

Understand performance at a systems level (CPU, memory, networking)

Have operated services in production and handled incidents and debugging

Understand distributed systems fundamentals and tradeoffs

Think end-to-end about request flows rather than isolated components

Can balance correctness, latency, and development speed

Collaborate effectively across engineering, ML, and product

DBMS (OSS or SaaS) and cloud infrastructure

High-load web applications or large-scale APIs

Performance-critical systems (e.g. trading platforms)

Low-level performance tuning and optimization

Open-source contributions

Competitive programming or CTFs

SHAD or similar advanced programs

Conference talks or technical publications

We conduct coding interviews as part of the process.
