Hi! Were EMCD - a rapidly growing ecosystem of crypto products including a Wallet P2P platform mining pool cloud mining and more. Our mission is to empower people to use money for creation not survival.

With over 7 years on the market and active international expansion were now launching a new strategic direction focused on building the next generation of mining infrastructure.

About the Team

We are the product team responsible for all money movement inside the company.
Were building an internal custodial platform - essentially our own bank: balance accounting transactions and their full lifecycle through processing.

The platform consists of two major components:

1. Custodial off-chain core - internal balances ledger entries and all money-related business logic.
2. Blockchain processing layer - connectors/adapters to various networks statuses fees retries.

Right now were strengthening the custodial off-chain core: improving the reliability of our accounting model defining clear interaction protocols with the processing layer and ensuring predictable system behavior as load and functionality grow.

Were looking for a Senior Backend Engineer who will help us design build and evolve this core and the integrations around it.

What you will do:

• Work on the service responsible for internal balances and all money movements
  (holds debits refunds internal transfers ensuring the correctness of all ledger entries - the numbers must alwaysreconcile).
• Integrate the core with internal processing systems and the blockchain-facing adapters
  (designing and implementing interaction protocols: APIs events queues statuses).
• Participate in architectural discussions for services and integrations
  (thinking ahead about how the system will evolve and scale understanding reasonable trade-offs and helping find the right balance between ideal architecture and practical delivery).
• Collaborate closely within a unified team that brings together processing and the technical core: joint planning participation in code reviews and driving improvements in architecture code quality and development processes.

What we are looking for:

• 3 years of backend development experience.
• Tech stack: Go PostgreSQL Kafka gRPC RESTful APIs.
• You write clean maintainable code and value tests and code reviews.
• Youre comfortable working with an existing system: you know how to carefully refactor and reduce technical debt - not just rewrite everything from scratch.

What we offer:

• Remote-first culture work from anywhere;
• Competitive compensation in USD/USDT;
• Flexible schedule and a result-driven approach;
• Opportunity to lead and build high-load global-scale systems;
• A team of professionals in blockchain and fintech;
