We are seeking a seasoned Backend Engineer with deep expertise in decentralized finance (DeFi) to lead the architectural design and development of our client's high-performance DEX platform. You will be responsible for building the core components of a world-class trading environment, focusing on ultra-low latency, high concurrency, and uncompromising security.
Key Responsibilities
Architectural Leadership:
Design and develop the core server-side architecture for a Decentralized Exchange (DEX).
Core Module Engineering:
Lead the implementation of critical modules, including matching engines, order books, market data broadcasting, risk management, and clearing/settlement systems.
Infrastructure & Connectivity:
Develop and maintain high-performance trading gateways (REST/WebSocket), market data feeds, and K-line services.
Performance Optimization:
Ensure the stability and performance of high‑concurrency, low‑latency trading systems through rigorous JVM tuning and system‑level optimizations.
Resilience & Security:
Build foundational capabilities for data persistence, comprehensive logging, automated backups, and robust disaster recovery protocols.
Cross‑Functional Collaboration:
Partner closely with Smart Contract and Frontend teams to ensure seamless end‑to‑end integration across the entire trading lifecycle.
Required Qualifications & Skills
Educational Background:
Bachelor’s degree or higher in Computer Science, Software Engineering, or a related technical field.
Java Expertise:
8+ years of professional Java development experience, with mastery of multi‑threading, concurrency models, and JVM performance tuning.
DEX Domain Knowledge:
3+ years of direct experience in DEX/Exchange server‑side development, with a deep understanding of matching, clearing, and risk control workflows.
High‑Performance Frameworks:
Proven experience with
LMAX Disruptor ,
Chronicle , or similar high‑performance frameworks; familiarity with
Exchange‑core
architectures is essential.
Data Management:
Expertise in MySQL, Redis, and MongoDB, including advanced database design, index optimization, and distributed transaction management.
System Reliability:
Deep understanding of multi‑active database deployments and disaster recovery; ability to lead team‑wide emergency drills.
Messaging & Streaming:
Proficiency in Kafka (consumer groups, partitioning, persistence) and real‑time data processing.
Cloud & DevOps:
Hands‑on experience with Docker and Kubernetes (Deployment, Service, Ingress, Monitoring); proficiency with AWS or Alibaba Cloud ecosystems (EC2/ECS, RDS, OSS).
Preferred Attributes (Bonus)
Experience with EVM‑based on‑chain settlement, Oracles, and off‑chain data integration.
Familiarity with modern observability stacks, including Prometheus, Grafana, and ELK.
Polyglot capabilities: Ability to develop stable auxiliary services in
Golang
or
Node.js
for on‑chain data retrieval and analysis.
