Technical Lead C# (core trading system)
We're looking for a Technical Lead (C#/.NET) to take architectural and technical ownership of the core trading systems behind EMCD's crypto exchange. This role sits at the center of the platform: matching engine, risk management, spot trading, and derivatives. It's a position for someone who understands that every microsecond, every edge case in order handling, and every liquidation scenario directly affects the product.
Responsibilities:
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
Requirements:
7+ years of commercial experience with C# / .NET, including at least 2–3 years 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
What We Offer:
Fully remote work from anywhere in the world
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
