- Node Integration: build the middleware that connects Go/JS services to the core blockchain network
- Scalability: optimize backend services for low latency and high availability
- Security: implement industry‑standard security practices for handling sensitive data
Requirements
- Strong proficiency in Go (Golang) or Node.js (JavaScript/TypeScript) with deep understanding of asynchronous programming and microservices
- Experience building DEX components, API gateways, or indexing services
- Expertise in designing and implementing RESTful or GraphQL APIs
- Experience with both SQL (PostgreSQL) and NoSQL (Redis/MongoDB) for real‑time data tracking
- Ability to build thread‑safe systems handling thousands of concurrent user requests
Benefits
- Health & Prevention: Comprehensive, high-tier medical insurance with a focus on preventative medicine, annual executive health screenings, and diagnostic check‑ups.
- Fitness & Wellness Programs: Monthly fitness allowances for premier gyms and studios, plus internal wellness initiatives including yoga, ergonomics workshops, and stress management.
