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
Strong Plus
- HFT, market-making, or ultra-low-latency trading systems experience
- Virtualization / hypervisors / TEE development
- Kernel-adjacent or embedded systems work
- Solana or blockchain infrastructure experience
$200,000 - $230,000 a year
-Salary based on experience
-Above market compensation and multiple forms of equity
-100% employer paid health benefitsÂ
-All-expenses-paid team retreats and conferencesÂ
-Weekly meal voucher

What does a Rust developer in web3 do?
A Rust developer in the context of web3 is a programmer who uses the Rust programming language to build applications and tools for the decentralized web, also known as the web3 ecosystem
The specific responsibilities of a Rust developer in web3 may vary depending on the project or organization they are working for, but in general, they would be responsible for writing, testing, and maintaining Rust code that is used to build web3 applications
This could include things like creating smart contracts for decentralized finance (DeFi) applications, building tools for interacting with decentralized storage networks, or developing decentralized applications (dApps) for the web3 ecosystem.
