$220K/yr - $275K/yr
10+ years expJito Labs is architecting the future of high-performance distributed systems on Solana, and they are seeking a senior engineer to work across application code, operating systems, hardware behavior, and network protocols. The role involves building latency-sensitive infrastructure and debugging complex issues in networking and Linux systems.
BlockchainInformation TechnologyOpen Source
Responsibilities
Debug and optimize network performance end-to-end: NIC tuning, congestion control, packet pacing, queueing disciplines
Analyze traffic using tcpdump, Wireshark, and custom tooling; reason about protocol behavior under load
Work with protocols beyond TCP/UDP when required (e.g., ICMP, IGMP, multicast)
Experience with high-performance I/O and kernel-bypass techniques such as DPDK, XDP, io_uring, or similar
Read and reason about Linux kernel source when debugging requires it
Understand networking stack internals (socket buffers, congestion control, netfilter, scheduling interactions)
Build bespoke tooling when existing observability is insufficient
Work fluently with kernel interfaces used by performance-sensitive systems
Use hardware performance counters, perf, eBPF, and flamegraphs to locate real bottlenecks
Reason about practical CPU behavior: cacheline contention, branch misprediction, NUMA effects, memory ordering
Understand IRQ affinity, scheduling behavior, paging, and TLB effects under real workloads
Willing to read assembly when the situation calls for it
Strong low-level systems programming background
Contribute to infrastructure, tooling, and occasionally upstream projects
Qualification
Required
10+ years of experience in systems programming, networking, or performance-critical infrastructure
Deep Linux expertise, including kernel behavior, networking internals, and performance tuning
Proficiency with packet analysis and network debugging tools
Experience with performance profiling and tracing (perf, eBPF, flamegraphs, etc.)
Strong programming fundamentals; depth matters more than language
Track record of diagnosing complex issues spanning application, OS, and hardware layers
Clear, direct communication
Strong low-level systems programming background
Solid understanding of algorithms, data structures, and writing correct concurrent code
Preferred
Experience in domains where latency and performance are first-order constraints (e.g., HFT, real-time systems, low-latency networking, kernel-adjacent infrastructure, high-performance distributed systems)
Custom memory allocators or deep memory subsystem optimization
Virtualization internals and passthrough networking (SR-IOV, vDPA, etc.)
Kernel-adjacent work (eBPF programs, driver debugging, custom modules)
Solana or blockchain infrastructure experience
Benefits
