- Implement billing logic that calculates electricity consumption based on miner output
- Support USDC payments via Ethereum, Polygon, and BSC; integrate with Stripe for fiat
- Develop an admin dashboard to manage facility configurations, pricing, and user balances
- Collaborate with product owners to define system rules and business logic
Requirements
- 3+ years of experience with Node.js (Express or Nest.js)
- Strong experience with React and component-based frontend development
- Familiarity with PostgreSQL, MySQL, or any relational DB
- Experience working with REST APIs and third-party integrations
- Good understanding of backend architecture, auth, and state management
- Git proficiency and ability to work independently in a remote team
- Clear written and spoken English
Nice to Have
- Experience with AWS services (Lambda, S3, RDS, CloudWatch)
- Background in crypto, mining infrastructure, or IoT systems
- Familiarity with payment integrations (Stripe, stablecoins, Web3 wallets)
- Knowledge of data visualization libraries (e.g., Chart.js, Recharts)
What We Offer
- Remote-first work culture with flexible hours
- Interesting project in the crypto infrastructure space
- A chance to influence architecture and implementation decisions
- Long-term collaboration on additional phases of the platform
- Competitive compensation
