Senior Backend Engineer (Java) - FX / Trading

As a Senior Backend Engineer at Better Payment Network, you own the integrations that connect our stablecoin-native FX network to liquidity providers across 15+ emerging-market currencies. BPN, incubated through Binance Labs, serves licensed financial institutions handling cross-border payments for e-commerce sellers, traders, logistics companies, and digital entertainment businesses. You bring new liquidity providers live, ensure their prices flow into our pricing engine, and build the trading and settlement systems that sit directly on top of them.

What you'll do

• Own BPN's integrations with liquidity providers (FX banks, OTC desks, exchanges, local VASPs) over REST, WebSocket and FIX.
• Build market data and pricing infrastructure: aggregate LP quotes into a single feed for our pricing engine, and process real-time order book and tick data.
• Build LP routing and failover logic so flow moves to the next provider when one is down, slow or off-market.
• Develop the FX trading system around these integrations, including orders, positions and hedging.
• Take part in clearing and settlement across T+0, T+1 and T+2 cycles.
• Integrate payment channels with banks and PSPs.
• Work directly with LP and bank technical teams across time zones to debug issues and agree on specifications.

What you bring

• At least 5 years of Java backend development with strong fundamentals in the JVM and concurrency.
• Hands-on experience building trading systems in FX, crypto, brokerage or market making.
• Production experience with Netty, Kafka and Redis.
• Comfort with Linux and MySQL or PostgreSQL.
• Fluent English, spoken and written, as you will run technical calls with global liquidity partners yourself.

Nice to have

• FX platform experience with knowledge of FX derivatives: CFDs, FX forwards, interest rate swaps.
• Liquidity integration experience: LP connectivity and the FIX protocol.
• Clearing, settlement or payment systems experience including T+N settlement and cross-border payments.
• High-concurrency, low-latency system optimisation.
• Ledger and bookkeeping systems, or automated settlement.
• Background at a brokerage, exchange or fintech.
• Experience with stablecoins, on-chain transfers, or local rails such as PIX (Brazil) and SPEI (Mexico).
• Mandarin Chinese.

What we offer

• Work on a liquidity layer already live and processing real volume.
• Small, fast team where your integrations go to production in weeks, not quarters.
• Direct exposure to trading, treasury and some of the fastest-growing payment markets in the world.
