Jito Labs

Product Manager

• Own product vision and roadmap for mobile, from concept through launch
• Drive rapid iteration cycles. Ship, measure, learn, repeat
• Lead user research to validate what we’re building
• Establish product metrics and instrumentation to guide decisions
• Make hard calls on prioritization, scope, and tradeoffs to maintain velocity
• Coordinate go-to-market with marketing and growth teams
• Contribute to company strategy as part of the leadership team

Head of Product – Mobile

Systems Engineer

• 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
• Strong low-level systems programming background
• We work primarily in Rust, but strong experience in C or C++ is equally relevant
• Solid understanding of algorithms, data structures, and writing correct concurrent code
• Contribute to infrastructure, tooling, and occasionally upstream projects

Staff Systems Engineer – Low Latency, Networking

• 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
• 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)
