Job description

Skill Sets:

async runtimes, Datastructures and Algorithms, zero-copy designs, efficient serialization/deserialization, memory pooling, and minimizing allocations

Key Responsibilities:

• ? ?Design and develop core engine components responsible for orchestrating workflows and enforcing system constraints.
• ? ?Optimize for concurrency, performance, and reliability in critical transaction paths.
• ? ?Conduct rigorous performance benchmarking, profiling, and optimization of high-throughput workloads.
• ? ?Guide technical design, architecture reviews, and uphold code quality standards across the engineering team.
• ? ?Embed security and risk controls directly into system components, ensuring adherence to engineering safety standards.
• ? ?Design systems with predictable latency and high throughput under sustained production workloads.
• ? ?Identify and eliminate performance bottlenecks involving CPU caches, cache-line contention, false sharing, branch misprediction, memory bandwidth, and synchronization overhead.

Qualifications:

• ? ?Minimum 3 years of hands-on experience in Rust.
• ? ?Mastery of systems-level programming, asynchronous p
