The posting

EMCD is a global crypto ecosystem building products across mining, wallets, payments, custody, and digital asset infrastructure. We are looking for a Senior Go Developer to join one of our backend teams and work on high-load services across financial and mining products. Depending on the team, you may work on transaction lifecycle and money flows, core archtecture tasks, or modernization and migration of core mining services.

Responsibilities

  • Build new backend services in Go and improve existing products
  • Integrate external providers via REST and internal services via gRPC and Kafka
  • Refactor legacy services to reduce support cost, simplify architecture, remove technical debt, and improve test coverage
  • Improve monitoring, logging, alerting, and security for financial flows
  • Support production systems, investigate incidents, and track operation lifecycle end to end
  • Provide technical mentorship within the team

Requirements

  • Production experience with money operations in fintech or crypto: holds, debits, credits, balances, transaction lifecycle, and reconciliation
  • Strong understanding of how to store and move money between systems safely: decimal precision, operation keys, idempotency, consistency, and auditability
  • Strong production experience with Go, PostgreSQL, gRPC / REST, and Kafka
  • Real experience applying microservice patterns to financial systems: Saga, compensation, distributed transactions, outbox, idempotent consumers, and reconciliation loops
  • Experience integrating external providers via REST, including timeouts, provider-side statuses, delayed reversals, and our side / their side reconciliation
  • Strong PostgreSQL beyond CRUD: transactions, isolation levels, unique constraints, locks, indexes, and EXPLAIN
  • Strong Kafka knowledge: partitions, consumer groups, offsets, rebalancing, delivery guarantees, ordering, and safe horizontal scaling
  • Active use of AI agents in development, with a practical understanding of spec-driven workflows and harness building

What We Offer

  • Fully remote work from anywhere in the world
  • Flexible working hours focused on results
  • 20 paid vacation days + 12 additional bonus days
  • 100% paid sick leave
  • Paid English lessons
  • Support for courses, certifications, and training programs
  • Real ownership in fintech and crypto infrastructure projects

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
