C# Developer

EMCD operates a cryptocurrency exchange platform, focusing on core trading systems including matching engines, risk management, spot trading, and derivatives.

• Own the matching engine and order lifecycle: limit, market, stop, post-only, IOC, FOK, self-trade prevention, partial fills;
• Develop and improve the risk engine for derivatives: cross/isolated margin, PnL and funding calculations, liquidation flows, ADL, insurance fund logic;
• Define and evolve the consistency and persistence model of the trading core: event sourcing, trade journal, snapshots, replay, crash recovery without order loss;
• Design reliable interaction patterns between the trading core and surrounding systems: gateways, custody, market data streams, clearing services;
• Set and monitor latency and throughput targets, and build the tooling to measure them: benchmarks, load environments, profiling under production-like traffic.

• 7+ Years of commercial experience with C# / .NET;
• 2–3 Years of experience as a Tech Lead or Architect;
• Hands-on production experience with matching engine and at least one of the following: exchange gateway, risk engine, or market data feed;
• Proven experience building low-latency, high-throughput systems;
• Direct experience working on a centralized crypto exchange (CEX) with real order flow and real money;
• Deep understanding of trading primitives: order types, margin trading, perpetual futures, funding rate, liquidations, ADL, maker/taker logic, fee tiers;
• Strong knowledge of distributed systems: consistency, idempotency, exactly-once semantics, queues/streams (Kafka, NATS, or similar), replicated state, fault tolerance;
• Experience writing and maintaining architecture documentation (ADR, design docs);
• Experience leading teams: hiring, 1:1s, incident review, development and release processes;
• Nice to have: Experience with DEX infrastructure or hybrid exchange models (CEX + on-chain settlement), understanding of regulatory requirements relevant to exchanges: KYC/AML, market surveillance, best execution.

• Flexible working hours focused on results;
• 28 Calendar days of vacation + 12 additional bonus days;
• Paid sick leave with no bureaucracy;
• Compensation for courses, certifications, and training programs;
• Real ownership of one of the most critical parts of the exchange infrastructure.
