Backend Engineer (Go/JS) – DEX & Web Services

All open positions

We are looking for two Backend Engineers to build the scalable infrastructure for a decentralized exchange and suite of web services integrated with the Bitcoin ecosystem.

Core working hours: 10am–1pm CET.

Responsibilities

• Service Development: develop and maintain the backend microservices that power the exchange and the wider web service ecosystem
• Order Management: implement the logic for off‑chain order books, trade matching, and real‑time liquidity monitoring
• 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.
• Competitive Compensation: Salary paid in your choice of fiat, Bitcoin, or stablecoins. ML token allocation and vesting for senior roles.
• Relocation Support: Full assistance with UAE residency visas and relocation to Abu Dhabi for on‑site roles. We handle the paperwork.
• Flexible Working: Structured flexibility across on‑site, hybrid, and fully remote roles. Core overlap hours respected across time zones.
• Global Team Meetups: Periodic gatherings with the full team around the world. The remote team is never remote from the culture.
