Apply for this job
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.
