Responsibilities
- Design and implement high-throughput, low-latency Rust engine components and data-processing pipelines.
- Build thread-safe, lock-free, or fine-grained-locked data structures and state machines for multi-core architectures.
- Develop custom thread pools, task schedulers, execution queues, priority scheduling, and resource-allocation controls.
- Implement efficient recursive algorithms, tail-call optimizations, and cache-friendly data structures.
- Use Rust ownership, lifetime annotations, custom allocators, and non-blocking I/O to reduce allocations and achieve predictable latency.
- Conduct benchmarking, flame-graph analysis, memory profiling, and CPU SIMD/vectorization optimization.
Requirements
- Deep experience with Rust internals, functional traits, closures, move semantics, macro systems, unsafe Rust boundaries, and memory management.
- Strong knowledge of memory models, cache coherence, atomic operations, memory ordering, Send/Sync traits, Mutex, RwLock, and message-passing channels.
- Experience implementing task schedulers, priority assignment, work-stealing thread pools, priority queues, and high-performance concurrent systems.
- Knowledge of cache alignment, SIMD vectorization, memory-mapped files, and lock-free or wait-free data structures.
- At least 5 years of software engineering experience and 3+ years writing production-grade Rust, or a strong C/C++ background transitioning to production Rust.
- Proficiency with profiling and debugging tools including perf, flame graphs, Criterion, Coz, tokio-console, and tracing.
- Preferred: experience with jemalloc, mimalloc, bare-metal or no-std Rust, Tokio internals, custom Future implementations, NUMA-aware architectures, and C/C++ or WebAssembly FFI.
