Paxos Labs builds enterprise infrastructure for trusted onchain financial products, working with major financial platforms to bring digital assets and DeFi into mainstream use.
You will focus on building Transit, a liquidity orchestration and distribution network for tokenized assets. Tokenization is producing thousands of onchain assets—stablecoins, tokenized money market funds, commodities, equities, private credit—but issuers face a critical problem: their assets remain illiquid and inaccessible until integrated into wallets, swap interfaces, aggregators, and lending venues. Today they solve this by renting liquidity from market makers at 20%+ cost of capital and negotiating venue-by-venue integration. Transit is the network they join instead, providing efficient routing, day-one distribution across integrated venues, and programmatic revenue sharing.
Transit consists of two core parts: a highly-performant crosschain exchange with an orderbook that aggregates gasless crosschain orders and guarantees solvency, and an enterprise RFQ—a real-time orchestration engine that aggregates DEX and solver liquidity, manages LP inventory, enforces compliance, and provides predictable pricing for enterprise clients.
In this role, you will:
- Research, design, and build core services behind Transit's RFQ orchestration engine: pricing, quoting, routing, inventory management, and settlement across chains and venues
- Research, design, and build core services behind Transit's exchange orderbook: matching engine, pricing rules, order APIs, and onchain settlement
- Own systems end-to-end from design through deployment, monitoring, and on-call operations for systems moving real money
- Build rate-aware pricing and inventory controls for volatile assets
- Integrate new chains, venues, solver networks, and liquidity sources, progressively reducing integration cost
- Build the execution attribution and economics layer enabling programmatic integrator revenue share
- Work directly with onchain infrastructure: contracts, mint/redeem facilities, and compliance enforcement
- Set technical direction on a small team where individual decisions carry significant weight, and raise the engineering bar through review and mentorship
Paxos Labs is a small team of roughly 15 people, meaning engineers own whole systems rather than slices and ship to production within weeks of joining. The problems are unusually hard for a company this size because customers are institutions and the correctness bar is the one finance holds, not the one crypto often settles for.
REQUIREMENTS
Required Experience:
- 6+ years building and operating production backend systems with true ownership of systems that had to stay up
- Track record of building systems 0 to 1 and then hardening them, rather than only maintaining mature ones
- Experience with systems where correctness is financial: exchange infrastructure, trading, settlement, or similar
Required Knowledge:
- Understanding of traditional exchange market structure such as CLOBs, batch auctions, RFQs, or similar—across economic, incentive, and technical design
Nice to Have:
- Experience at a market maker, exchange, or trading firm
- Multi-chain infrastructure experience, especially inventory or treasury management across chains
- Prior work on tokenized assets, stablecoins, or RWAs
- Understanding of onchain market structure: AMMs, solver networks, DEX aggregators, bridges, etc.
- Ability to read Solidity and reason about contract interactions, even if you don't write smart contracts
- Judgment about latency, inventory risk, and execution quality, and ability to explain pricing decisions to commercial stakeholders
