• Expertise in operating system and network stack internals (Linux kernels, scheduling, memory/IO subsystems, TCP/IP).
• Strong software engineering background with hands‑on experience with performance profiling and observability.
• Ability to write and reason about performant code at a low level (C, raw sockets, CPU/vector instructions, memory/cache optimization).
• Familiarity with high‑performance IO paths; understanding of cross‑region networking and latency trade‑offs.
• BS/MS in Computer Science, Electrical/Computer Engineering, or equivalent practical experience; proven technical leadership and mentoring.

• Expertise in virtualization/containers.
• Java performance experience: JVM/JIT/GC internals, JFR/async‑profiler, and benchmarking.
• Low‑level engineering skills in C/C++/Rust/Go, with demonstrated ability to analyze instruction‑level hotspots, memory/cache behavior, and concurrency.
• Database or storage performance specialization (query execution, indexing, IO path optimization).
