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.

What We Do
ABOUT BLOXROUTE
bloXroute is the "Flash Boys" for DeFi. It created the first and only high-performance blockchain distribution network (BDN) with the best solution for Ethereum, BSC, and Polygon. The bloXroute BDN and DeFi trading tools allow its users to win at crypto trading. The BDN utilizes a global network of servers optimized for network performance. Nodes access this network through open-source gateways and users can access it through the bloXroute public-API.
The BDN network propagates blockchain transactions and blocks closer to the speed of light. It provides traders with the speed and reliability required for crypto transactions. bloXroute is the leader in mempool services, block streaming and anything Defi performance.
The BDN also allows blockchains to scale by speeding the time it takes to communicate the current state. The BDN's fast communication reduces the blocks’ size and frequency limits. This is true for all consensus mechanisms, including Proof of Stake, Proof of Work, and DAGs.
We are hiring engineers and business people for various positions. Check out our careers page: https://bloxroute.com/careers/
We offer competitive compensation and equity, a full remote environment and a bunch of smart team members to work with
