About TransFi
TransFi is a stablecoin-native cross-border payments company headquartered in Singapore. We move money across 70+ countries, supporting 40+ currencies and 250+ local payment methods across Latin America, Southeast Asia and Sub-Saharan Africa, with an engineering team of around 40.
The role
You'll build and operate the systems that quote prices and manage inventory across crypto markets. Concretely:
- Design and build the pricing engine — order book analysis, depth-aware pricing, spread and markup logic
- Build the risk layer: inventory and exposure limits, position monitoring, kill switches, circuit breakers
- Handle the failure modes that matter — stale market data, venue outages, partial fills, self-trade and price-drift protection
- Integrate with exchange APIs and our existing payment and treasury infrastructure
- Work directly with the treasury trading desk on what they actually need, and with our CPTO on architecture
What we're looking for
- Experience building or operating market making, algo trading or exchange systems — this is the non-negotiable one
- Strong grasp of order books, inventory risk, adverse selection, and what goes wrong when a quoting system meets a thin market
- Comfortable owning production systems that move real money, including on-call for them
- Backend depth in Python, and Javascript
- Able to work closely with a trading desk and translate their intent into system behaviour
Nice to have
- Crypto exchange experience, particularly Binance APIs or P2P markets
- Background at a prop trading firm, market maker, or crypto exchange
- Exposure to regulated financial infrastructure
