Senior Software Engineer - JTX

Jito Labs

120d • Remote

About The Position

We're building JTX, a next-generation trading app that brings the speed, power, and sophistication of Solana’s market infrastructure directly to traders. This is a true 0-to-1 product effort focused on creating an experience that serious on-chain traders actually want to use — fast, intuitive, high-performance, and deeply connected to the mechanics of the market itself.
You’ll work alongside the team behind some of the leading infrastructure powering billions in daily transaction value on Solana, translating complex systems and market behavior into a seamless trading experience for users. Whether it’s shaping workflows, refining interfaces, improving execution visibility, or helping define the product from the ground up, this role will have a direct hand in building what trading on Solana looks like next.
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.

Requirements

• 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
• Comfortable operating with high autonomy and incomplete information. This is a 0-to-1 product, not a mature codebase

Nice To Haves

• Familiarity with Solana's runtime, transaction lifecycle, and market microstructure (MEV, block building, execution quality) is a strong plus
• Trading systems or exchange infrastructure
• DeFi protocol engineering
• Fintech backend systems (payments, custody, execution)
• High-frequency or low-latency systems
• Security engineering

Responsibilities

• 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

Benefits

• Competitive compensation including salary and token incentives
• The tools you need to do your best work
• A seat at the center of Solana's market infrastructure alongside some of the strongest engineers in the ecosystem
