- это финтех-компания, которая предлагает современную инфраструктуру on/off-ramp и web3 для обеспечения первоклассного пользовательского опыта.

What you bring:
• 5+ years TypeScript/Node.js in production. NestJS for 2+ years — modules, guards, interceptors, microservice transports.
• Deep PostgreSQL: schema design, indexing, EXPLAIN ANALYZE, zero-downtime migrations, database-per-service pattern.
• eal microservices experience — RPC + pub/sub, message brokers, idempotency, eventual consistency, saga/outbox. Not a monolith split into folders.
• Production blockchain (MUST-HAVE) — HD wallets (BIP32/BIP39), smart contracts, ABI, multichain, on-chain transactions with real user funds. ethers.js / viem / @solana/web3.js.
• AI-driven workflow (MUST-HAVE) — you use Claude, Copilot, or Cursor daily. You've built automations or LLM-powered tools, not just prompted ChatGPT for code snippets.
• English Upper-Intermediate. Russian — fluent.

Nice to have:

NATS JetStream (streams, consumers, delivery policies), observability stack (OpenTelemetry, Prometheus + Grafana, pino, distributed tracing), Kubernetes with Helm/Kustomize, fintech domain (PCI DSS, KYC/AML, payment systems), experience mentoring mid-level engineers, React basics for back-office UIs.
