Principal Permance Kernel Engineer

Principal Performance & Kernel Engineer

Responsibilities

• Architect and automate bare-metal, zero-latency environments with customized Linux/Unix kernel tuning, real-time schedulers, and deterministic execution
• Rip apart and optimize every subsystem: CPU affinity, IRQ routing, TCP/IP stack, NUMA balancing, context switch reduction, memory allocators, BIOS configs
• Design, deploy, and manage high-bandwidth, low-jitter, zero-packet-loss networking setups
• Own kernel bypass, SmartNIC offloads, RDMA, DPDK pipelines — if it touches a packet, you control it
• Build battle-hardened telemetry (eBPF, perf, custom probes) to capture system metrics at nanosecond precision
• Hunt and kill latency regressions with no mercy
• Partner directly with hardware vendors and firmware engineers to squeeze every cycle out of silicon
• Lead crisis-mode performance war rooms when stakes are highest.

Requirements

• Master of Unix/Linux: You dream in syscalls and kernel parameters
• Networking Savant: TCP, UDP, Ethernet, multicast, PTP — understood at the wire level
• Code Warrior: You automate and hack in C, Python, Bash, Go — whatever gets it done
• Hardware Whisperer: You know how CPU caches, NIC queues, PCIe buses, and memory hierarchies behave under pressure
• Relentless Diagnostician: You bring scientific method discipline to debugging, benchmarking, and tuning.
