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. 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.
