Apply for this job

Jito Labs is architecting the future of high-performance distributed systems on Solana. We're the team behind Jito-Solana, the leading MEV Solana client, and the Jito Block Engine, which has revolutionized block building on Solana. The Block-Engine has generated roughly 4.5 million SOL for validators and stakers over the past year.

Our latest product, BAM, reimagines Solana market structure and the transaction supply chain with a heavy emphasis on performance, reliability, and transaction privacy. We're looking for a senior systems engineer with strong Linux systems and low-level performance experience who enjoys working at the boundary between software, operating systems, and hardware.

Why Jito

We're a small, profitable company with product-market fit. That means:

High ownership: You drive significant technical decisions and shape product direction

Fast execution: We ship rapidly and iterate on real-world feedback

Technical excellence: Complex problems, elegant solutions

Sustainable: Strong financials let us focus on long-term impact, not runway

About the Position

We are seeking an exceptional Senior Systems Engineer to join our core team building critical, next-generation infrastructure for the Solana ecosystem. You'll be exploring uncharted technical territory and building novel solutions across our stack:

Systems & Infrastructure Engineering

Build and operate high-performance Linux systems for transaction processing and block building
Work with virtualization and isolation technologies (KVM, QEMU, TEEs)
Debug and optimize interactions between user-space systems and the Linux kernel
Reason about CPU performance, memory, I/O, and scheduling under real-world load

Performance Engineering

Build high-performance systems for processing and analyzing on-chain data
Optimize critical paths in our infrastructure and Solana core (Agave & Firedancer) to reduce latency and increase throughput
Develop new tools for monitoring and improving network efficiency
Improve system reliability through careful design, observability, and fault isolation
Contribute performance improvements upstream (Solana / OS / QEMU related components)

Requirements

5+ years of systems-level programming in C, C++, or Rust (we use Rust)
Deep experience with Linux systems engineering and performance-critical infrastructure
Proficiency with profiling and tracing tools: perf, flamegraphs, eBPF
Experience debugging network performance (tcpdump, Wireshark, packet capture analysis)
Familiarity with CPU microarchitecture concerns (cache behavior, branch prediction, NUMA)
Willingness to dive into complicated systems to accurately root cause and fix issues
Clear, simple communication
