Job Description:

We are looking for an experienced Backend Engineer to help build and scale the core trading infrastructure that powers Reya’s next-generation on-chain markets. You will work on latency-sensitive systems that support high throughput, reliability, and data integrity under real-world load. You’ll collaborate closely with protocol engineers, core developers, and system architects to design and implement backend components critical to order execution, market data processing, and distributed event-driven systems.

Job Responsibility:

Design, implement, and maintain backend services for high-performance trading systems and market infrastructure
Build messaging and streaming systems powering real-time data flows and order execution (e.g., Redis Streams, Kafka, or similar)
Develop robust event-driven systems to support concurrency at scale and consistent execution semantics under heavy load
Optimize database schemas and access patterns for extremely high concurrency and low-latency performance
Collaborate with cross-functional teams to ensure scalable and fault-tolerant backend architecture
Monitor, profile, and tune services to meet performance SLAs in production
Contribute to architectural discussions and drive improvements in system reliability, observability, and scalability

Requirements:

5+ years of professional experience building backend systems with a strong focus on performance and reliability
Proficiency in Rust (or equivalent systems programming) for backend service development
Practical experience with messaging / streaming systems such as Redis Streams, Kafka, or similar
Deep understanding of databases under high concurrency and techniques to mitigate contention, scale reads/writes, and ensure consistency
Experience with event-driven architectures and building asynchronous, distributed systems
Comfortable building and scaling systems that handle 1,000+ executions/sec today with design foresight for 10×–100× future growth

Nice to have:

Background in trading systems, exchanges, market infrastructure, or related areas
Experience with financial markets concepts such as order books, matching engines, reconciliation and risk systems
Familiarity with blockchain / decentralized finance (DeFi) protocols or similar high-performance distributed systems

What we offer:

Competitive compensation and full remote flexibility
Impactful work — contributions go directly into protocol and platform performance
