# Senior Software Engineer - Special Projects **Location:** USA **Department:** Engineering **Workplace Type:** Remote ## About the Position We're building a new application that brings the power of Solana's market infrastructure directly to users. This is a 0-to-1 effort backed by the team that built the leading infrastructure powering billions in daily transaction value on Solana. We're looking for a senior engineer to join a small, scrappy team with full ownership over this product. You'll work alongside world-class designers and engineers who have built products used by millions. The work spans backend services, real-time data pipelines, and everything in between. You'll build systems that are fast, reliable, and secure from day one. If you've spent time thinking about how markets actually work on Solana and want to build the product layer on top of that, this is the role. ## What You'll Do - Design and build core systems for our new product from scratch - Build low-latency, high-reliability services that interact directly with Solana's transaction and block building pipeline - Own critical infrastructure: order routing, execution, real-time market data, and position management - Implement security at every layer, from transaction signing to user data protection - Work closely with the product and infrastructure teams to ship fast and iterate based on real user feedback - Make significant architectural decisions as an early member of the team ## What We're Looking For - 5+ years of software engineering experience, with meaningful time spent on distributed systems - Strong systems programming skills. Rust preferred, but deep experience in C/C++, Go, or similar is fine - Track record building reliable, low-latency systems in production - Security-first mindset. You think about attack surfaces, key management, and failure modes before writing code - Familiarity with Solana's runtime, transaction lifecycle, and market microstructure (MEV, block building, execution quality) is a strong plus - Comfortable operating with high autonomy and incomplete information. This is a 0-to-1 product, not a mature codebase ## Relevant Background If you have experience in any of the following, you may be a good fit: - Trading systems or exchange infrastructure - DeFi protocol engineering - Fintech backend systems (payments, custody, execution) - High-frequency or low-latency systems - Security engineering ## Compensation & Benefits **Salary Range:** $200,000 - $250,000 a year - Salary based on experience - Above-market total compensation and multiple forms of equity - 100% employer-paid health benefits - All-expenses-paid team retreats and conferences - Weekly meal voucher and other benefits ## About Jito **Jito** builds the Market Layer of Solana, the infrastructure that powers real markets on-chain. We started by building foundational network infrastructure: execution systems, capital markets, and incentive mechanisms that process billions in daily transaction value. Our products (Jito Block Engine, BAM, and JitoSOL) are market leaders and core to how Solana's economy operates. Now we're moving up the stack. We're building the consumer product that helps people access better financial services, backed by the same world-class team that built the infrastructure powering billions in daily transaction value. We're a small, profitable company with product-market fit. That means: 1. **High ownership:** Every team member drives significant technical decisions and shapes our product roadmap. 2. **Fast execution:** We ship rapidly and iterate based on real-world feedback. Progress, not motion. 3. **Technical excellence:** We tackle complex problems with elegant, scalable solutions. 4. **Sustainable growth:** Strong financials and proven market fit enable us to focus on long-term impact. We offer competitive compensation, significant equity, and the opportunity to work on problems that matter. --- *When applying, mention the word CANDYSHOP to show you read the job post completely.*

Staff Systems Engineer - Low Latency & Networking

Jito Labs

77 days ago

**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 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 are building systems that operate at the edge of what modern hardware and networks can sustain. We're looking for a senior engineer who is comfortable working across application code, operating systems, hardware behavior, and network protocols — someone who enjoys debugging the kinds of problems where the root cause might live anywhere in the stack. ### About the Position We build latency-sensitive infrastructure where microseconds matter and root causes are rarely obvious. This role is for someone who can move comfortably between application code, kernel internals, hardware behavior, and network protocols — debugging a TCP retransmission anomaly one day and reasoning about memory contention the next. You should be as comfortable reading kernel source and packet captures as you are writing production Rust. Much of the work involves ambiguous, cross-layer problems where existing tools and playbooks are insufficient and new ones must be created. This is a senior role for someone who has previously been the person others escalate to when nobody else can find the root cause. You'll work across: #### Networking - 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 #### Linux Systems - 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 #### Hardware & Performance - 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 #### Software Development - 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 ### Requirements - 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 Plus - 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 ### Why Jito We’re a small, profitable company with real product-market fit. That means: - **High ownership:** you drive major technical decisions and shape the direction of the system - **Fast execution:** we ship quickly and iterate on real-world behavior - **Technical depth:** the problems are real, complex, and intellectually demanding - **Sustainable:** strong financials allow us to focus on long-term impact, not runway ### Compensation & Benefits **$220,000 - $275,000 USD a year** - Salary based on experience - Above-market total compensation and multiple forms of equity - 100% employer-paid health benefits - All-expenses-paid team retreats and conferences - Weekly meal voucher *When applying, mention the word **CANDYSHOP** to show you read the job post completely.*
