Senior Software Engineer - Special Projects

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
