Job Description


We’re looking for a Senior Full-Stack Engineer with a strong backend foundation in Rust and deep experience in crypto, blockchain, DeFi, or trading infrastructure. You will architect and implement the backend systems that power decentralized trading, execution, and data services, while also contributing to full-stack integrations and product features when needed. 


This role sits at the intersection of backend engineering, distributed systems, and crypto-native development. 


What You’ll Build 


Backend (primary focus) 


• High-performance backend services in Rust or Go 

• Systems that integrate with smart contracts, wallets, price feeds, and oracles 

• Event-driven and streaming infrastructure for crypto execution pathways 

• Components related to risk, collateral, liquidations, trading logic, and system reliability 

• Infrastructure designed for low-latency, correctness, and fault tolerance 


Full-Stack Responsibilities 


• Build APIs and backend-to-frontend interfaces 

• Contribute to dashboards, tools, and product features when required 

• Ensure seamless integration between the backend and user-facing components 


Required Skills & Experience 


• 3+ years building production systems in backend or full-stack roles 

• Strong Rust or Go experience 

• Background in crypto, DeFi, blockchain infrastructure, or trading systems 

• Experience with distributed or event-driven architectures (Kafka, Redis Streams, async I/O) 

• Understanding of smart contract interactions, EVM or cross-chain integrations 

• Experience with high-performance or real-time backend pipelines 


Nice to Have 


• Experience with: 

– AMMs, vaults, oracles, liquidations, margining, or execution systems 

– Trading engines, low-latency systems, or HFT frameworks 

– Rust-based smart contract systems (CosmWasm, Anchor, Substrate) 

– Cross-chain messaging (LayerZero, Axelar, Wormhole) 

• Frontend experience with React, TypeScript, or Next.js 


Who You Are 


• Backend-strong engineer comfortable working across the stack 

• Cryptonative mindset: security, precision, performance, correctness 

• Communicative, ownership-driven, and autonomous 

• Curious about trading logic, risk engines, and high-throughput infra 


Why This Role 


• Build foundational crypto trading infrastructure 

• Contribute to complex real-time systems in a highly technical environment 

• Zero-bureaucracy culture, strong engineering standards 

  • • Fully remote work with global collaboration
