Senior Software Engineer – JTX at Jito Labs
Jito Labs is hiring a Senior Software Engineer – JTX to help build the next generation of on-chain trading infrastructure and products on Solana. This is a remote engineering position for experienced software engineers interested in distributed systems, low-latency infrastructure, trading technology, blockchain, and decentralized finance.
The position is listed for USA / Remote and offers an annual salary of $200,000–$250,000, in addition to competitive compensation and significant equity.
About Jito Labs
Jito Labs builds infrastructure for the Solana blockchain, focusing on the systems that support markets and high-value transactions on-chain.
The company describes its work as building the “Market Layer of Solana”, with infrastructure spanning execution systems, capital markets, and incentive mechanisms.
Jito's products include the Jito Block Engine, BAM, and JitoSOL, which are positioned as important components of the Solana ecosystem.
The company is now expanding further into the trading-product layer with JTX, a next-generation trading application designed to provide serious on-chain traders with a fast, intuitive, and high-performance trading experience.
About the Senior Software Engineer – JTX Role
As a Senior Software Engineer, you will help build JTX from the ground up.
This is described as a genuine 0-to-1 product development opportunity, meaning the successful candidate will not simply maintain an established application. Instead, they will help design and build core systems, make important architectural decisions, and contribute to defining the future trading experience on Solana.
You will work alongside engineers responsible for infrastructure that processes significant transaction volumes on the Solana network.
The role requires an understanding of performance, reliability, security, market behavior, and user experience. Engineers will be expected to translate complex blockchain and market infrastructure into products that traders can use efficiently.
Key Responsibilities
Build Core Systems
You will design and build core systems for JTX from scratch.
As an early member of the engineering team, you will have substantial influence over technical architecture, system design, implementation choices, and the evolution of the product.
Develop Low-Latency Infrastructure
The role involves building low-latency and highly reliable services that interact directly with Solana's transaction and block-building pipeline.
Performance will be an important consideration because JTX is designed for users who require fast execution and responsive market information.
Own Critical Trading Infrastructure
You will work on critical components including:
- Order routing
- Trade execution
- Real-time market data
- Position management
- Transaction processing
- Systems connected to Solana's market infrastructure
The engineer will need to design these systems for reliability and performance in a demanding on-chain environment.
Security Engineering
Security will be an important responsibility throughout the product.
You will implement security controls across multiple layers, including transaction signing and protection of user data.
The company expects engineers to think about potential attack surfaces, key management, system failures, and other security considerations before and during implementation.
Collaborate Across Teams
The Senior Software Engineer will work closely with product and infrastructure teams.
The objective is to ship quickly, gather feedback from real users, and continuously improve the product.
Because JTX is an early-stage product, engineers will have opportunities to influence both technical decisions and product development.
Requirements
Jito Labs is looking for candidates with at least five years of software engineering experience, including meaningful experience working with distributed systems.
Applicants should have strong systems-programming skills.
Rust experience is preferred, although engineers with deep experience in languages such as C, C++, Go, or similar systems-oriented languages may also be considered.
Candidates should demonstrate experience building reliable, low-latency systems that operate in production environments.
A strong security mindset is also important. Applicants should understand concepts such as attack surfaces, key management, failure modes, and secure system design.
Familiarity with Solana's runtime, transaction lifecycle, and market microstructure is considered a strong advantage.
Knowledge of areas such as MEV, block building, and execution quality can also help candidates stand out.
Because JTX is being built as a 0-to-1 product, applicants should be comfortable working with significant autonomy and dealing with incomplete information.
Relevant Background
Jito Labs highlights several professional backgrounds that may be relevant to the position.
Candidates with experience in any of the following areas may be particularly relevant:
Trading Systems
Experience developing trading platforms, exchange infrastructure, order-routing systems, or execution technology can provide useful experience for this position.
DeFi Engineering
Engineers who have worked on decentralized finance protocols and blockchain-based financial applications may have relevant technical knowledge.
FinTech Backend Systems
Experience building backend infrastructure for payments, custody, financial transactions, or trade execution can also be valuable.
High-Frequency and Low-Latency Systems
Candidates who have worked on high-performance systems where milliseconds and system reliability matter may find their experience particularly applicable.
Security Engineering
Security engineers with experience in transaction security, key management, application security, or infrastructure protection may also have relevant skills.
Compensation
The advertised salary for the Senior Software Engineer – JTX position is $200,000–$250,000 per year.
Jito Labs also states that it offers competitive compensation and significant equity.
The company describes itself as a small, profitable organization with product-market fit, allowing its team to maintain a high level of ownership while focusing on sustainable growth and technical excellence.
Why This Opportunity Is Different
The JTX project provides engineers with the opportunity to participate in the creation of a new trading product rather than joining a mature product where most architectural decisions have already been made.
Engineers can contribute to the design of systems responsible for order routing, execution, market data, positions, security, and other critical components.
The position also combines several technically demanding areas, including distributed systems, blockchain infrastructure, financial markets, low-latency engineering, and security.
Who Should Apply?
This opportunity is particularly relevant to senior software engineers who enjoy solving complex systems problems and want to work at the intersection of blockchain and financial markets.
Candidates with five or more years of engineering experience and a strong background in distributed systems should consider the position if they also have experience in trading infrastructure, financial technology, DeFi, security, or other high-performance systems.
Rust developers may have an especially relevant background, although the company indicates that strong systems engineers with experience in C, C++, Go, or similar languages can also be considered.
Applicants should also be comfortable working independently, making architectural decisions, and contributing to an early-stage product where requirements may evolve quickly.
How to Apply
The position is listed as USA / Remote. Candidates should review the current application page for the latest eligibility and location requirements before applying.
Conclusion
The Senior Software Engineer – JTX position at Jito Labs offers experienced engineers an opportunity to work on a new trading product built on top of Solana's high-performance blockchain infrastructure.
The role combines distributed systems, low-latency engineering, trading infrastructure, blockchain technology, security, and product development.
For engineers with experience in trading systems, DeFi, fintech, security, or high-performance backend infrastructure, the position provides an opportunity to contribute to a 0-to-1 product while working with a team building infrastructure for the Solana ecosystem.
