📋 Description

• Write high-performance, asynchronous, low-latency code that handles massive, non-blocking throughput on a single machine. • Dig into memory profiles, hunt down GC pressure, eliminate allocations, and design highly concurrent event-driven architectures. • Build and refine heavy asynchronous execution patterns, ensuring maximum thread efficiency and minimal latency overhead across massive workloads. • Design, develop, and maintain complex, scalable, and high-performance systems with a focus on non-blocking architectures and highly efficient, maintainable code. • Aggressively reduce memory allocations and GC pressure using profiling tools and advanced allocation techniques. • Identify and troubleshoot production issues, conducting low-level root cause analysis and implementing fixes to ensure strict system reliability. • Analyze and articulate the architectural trade-offs of different design choices.

🎯 Requirements

• A proven track record working in the performance-critical domains listed above, specifically dealing with heavy data streams or real-time processing. • Practical, battle-tested experience with asynchronous, event-driven, or multi-threaded programming. You understand how non-blocking I/O works under the hood and how to avoid common concurrency pitfalls. • You don’t just "know" data structures; you understand how computers fundamentally process them. You can easily explain the memory layout, cache-locality, and algorithmic trade-offs of choosing one structure over another from first principles. • Instantly recognize and describe strategies for managing large, fixed blocks of memory (e.g., bitmap allocators, free lists) and mitigating memory fragmentation. • Fluent in bit manipulation and pointer/offset arithmetic. You are capable of calculating the exact metadata and memory overhead of your own code blocks. • A great story about a time you used a memory or CPU profiler to hunt down a low-level bottleneck and solved it with a non-obvious, structural fix. • 4+ years of professional experience, primarily leveraged in performance-first environments using C++, C, Rust, C#, or Java.

🏖️ Benefits

• medical, dental, vision, disability and life insurance • 401(k) retirement savings with company match • an employee stock purchase plan • an employee referral program • flexible spending accounts • an Employee Assistance Program (EAP) • education assistance • parental leave • paid time off (PTO) • company-paid holidays • health and wellness events • community programs
