Job Description
Senior Software Engineer – Low-Latency, Async, Systems Programming, Cloud Security
Tenable
• 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.
Job 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.
