Role

Who you are

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

What the job involves

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
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

Our take

Decentralised finance – global, peer-to-peer, and third-party free – is set to change the way the world banks, but the blockchain technology it depends on is, transactionally, relatively slow. BloXroute aims to combat this issue, opening DeFi up to the masses, with a blockchain distribution network to let users avoid network congestion and receive critical trade information faster.

The peer-to-peer nature of DeFi requires everyone to be connected to everyone else in order to access info on, for example, prices or arbitrage opportunities. BloXroute supplies this connection, by propagating DeFi information quickly, which allows its users to make better trades. The network is blockchain agnostic, supporting a number of networks including Ethereum and Polygon, giving it high utility in the space.

Funding raised by the company can be expected to grow teams and expand business reach, and with the popularity of DeFi ever increasing, BloXroute should have all the room in the market that it needs to grow.
