Description

We are envisioning the future of high-performance distributed systems revolving around Solana at Jito Labs. Our team has developed Jito-Solana, a leading MEV Solana client, and the Jito Block Engine, which has transformed block building on the Solana network. Jito-Solana currently powers 88% of stake and 1,100 validators, generating an additional $370M in revenue for network stakers and validators.

At Jito Labs, you will collaborate with a small, agile group of engineers and operators dedicated to tackling complex technical challenges at the forefront of Solana trading and infrastructure. As a profitable company with a well-received product, we possess the ability to address ambitious technical hurdles while maintaining a startup's agility. Our team culture highlights:

  • Ownership: Every team member plays a significant role in shaping technical decisions and guiding our product roadmap.

  • Execution: We prioritize speedy delivery and iterate based on real-world feedback, emphasizing progress over mere activity.

  • Excellence: We tackle intricate problems with sophisticated, scalable solutions.

  • Growth: Our solid financial standing and market fit allow us to focus on long-term outcomes.

If you are enthusiastic about:

  • Resolving intricate distributed systems challenges

  • Engaging with advanced MEV and trading infrastructure

  • Contributing to open-source blockchain technology

  • Driving measurable enhancements on one of the fastest-growing L1 blockchains

…then we look forward to your application.

We are not simply creating tools but designing the future of high-performance distributed systems. Our efforts directly influence the Solana ecosystem, paving the way for a quicker network, enhanced capital efficiency, and more resilient DeFi applications for millions of users.

We provide competitive compensation, notable equity, and the chance to work on significant problems. Instead of just observing the blockchain future unfold, join us in shaping it.

I am seeking a world-class Systems Engineer / Rust Architect to build a proprietary asset extraction engine on the Solana network. This is not a "Web3 App" or a "DEX UI." This is a purely backend, low-latency machine designed to capture micro-value from market volatility.​The system mimics a "digital sluice," using high-precision math to harvest fractional differences that standard rounded-math bots ignore. We are scaling from a prototype to a 30-node distributed network managing 100+ concurrent execution "hands."​Core Technical Requirements​Low-Level Rust Mastery: You must be an expert in the Tokio runtime, asynchronous programming, and memory-safe mathematical operations.​Solana Network Physics: Deep understanding of the Sealevel runtime, custom WebSocket/Lumen bridges, and avoiding gRPC bottlenecks.​Jito & MEV Optimization: Proven experience with Jito Bundles, transaction shredding, and tip-optimization to ensure first-block inclusion.​Distributed Orchestration: Ability to architect a master-node system that manages 30+ regional nodes with seamless failover and zero-loss state management.​Precision Math: All logic must operate on u64 integers (Lamports) to avoid floating-point rounding errors. We do not "round" to the dollar; we capture the 9th decimal.​Key Responsibilities​Engine Hardening: Audit and optimize the core Rust logic for 0-latency execution.​Node Orchestration: Build the "Master Switch" to deploy, monitor, and update 30 nodes across global regions simultaneously.​The "Tax" Logic: Implement a secure, automated "sweeper" protocol that collects fractional value from all child-nodes into a master treasury without interrupting execution.​Redundancy: Ensure the system is "Anti-Fragile"—if a validator or node fails, the 50-drop safety protocol must trigger an instant failover.
