Principal Performance & Kernel Engineer

bloXroute is seeking an experienced Senior DevOps Engineer who is passionate about kernel internals, hardware-level optimization, and high frequency network transport-not just configuring VMs. You will be at the frontline of designing the fastest, leanest, most reliable systems.ResponsibilitiesArchitect and automate bare-metal, zero-latency environments with customized Linux/Unix kernel tuning, real-time schedulers, and deterministic executionRip 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 setupsOwn kernel bypass, SmartNIC offloads, RDMA, DPDK pipelines — if it touches a packet, you control itBuild battle-hardened telemetry (eBPF, perf, custom probes) to capture system metrics at nanosecond precisionHunt and kill latency regressions with no mercyPartner directly with hardware vendors and firmware engineers to squeeze every cycle out of siliconLead crisis-mode performance war rooms when stakes are highest.RequirementsMaster of Unix/Linux: You dream in syscalls and kernel parametersNetworking Savant: TCP, UDP, Ethernet, multicast, PTP — understood at the wire levelCode Warrior: You automate and hack in C, Python, Bash, Go — whatever gets it doneHardware Whisperer: You know how CPU caches, NIC queues, PCIe buses, and memory hierarchies behave under pressureRelentless Diagnostician: You bring scientific method discipline to debugging, benchmarking, and tuning.Originally posted on Himalayas
