Staff Rust Engineer – Core Infrastructure

This is a fully remote position, open to applicants in United States.

📋 Description

• Enhance Real-Time Infrastructure: Develop high-performance, memory-safe, and concurrent production code using Rust.

• Improve model serving infrastructure to attain ultra-low inference latency under significant concurrent request loads.

• Create low-latency data ingestion systems, microservices, and network protocols for processing real-time behavioral streams.

• Develop Core Architectural Tooling: Design and sustain robust, high-throughput backend APIs and SDKs.

• Implement tailored abstractions, caching layers, and memory management profiles to optimize hardware efficiency.

• Transition data-heavy bottlenecks from higher-overhead languages to highly optimized Rust components.

• Ensure Reliability and Scale: Take ownership of the complete lifecycle of core backend infrastructure components.

• Troubleshoot complex distributed system deadlocks, race conditions, and production bottlenecks in cloud environments.

• Establish thorough performance benchmarking, regression testing, and real-time system monitoring.

• Collaborate on Product Evolution: Work directly with Applied Scientists to translate recent advancements in neural networks and ranking models into scalable runtime implementations.

• Define best practices for constructing secure, scalable, and deterministic system architectures across our engineering organization.

⛳️ Requirements

• 6 to 8+ years of experience in Software Engineering, Systems Programming, Infrastructure Engineering, or a related field.

• Extensive professional experience in writing and deploying production-grade Rust code within high-scale systems.

• Profound understanding of Rust-specific features, including ownership, lifetimes, concurrency models, and asynchronous runtimes like Tokio.

• Experience in building robust backend systems, custom APIs, and event-driven architectures.

• Proficient in debugging, profiling, and managing high-throughput production systems under stringent real-world constraints.

• Ability to navigate ambiguity with a strong sense of technical ownership while balancing engineering speed and quality.

🏝️ Benefits

• At this stage, the efficiency and speed of our core infrastructure directly influence the performance of our product for global-scale consumer enterprises.

• You will enjoy the opportunity to architect core systems, engage with cutting-edge AI workflows, and play a pivotal role in defining the technical scalability of the company.
