Senior Backend Engineer, Exchange Infrastructure

Build Transit’s RFQ engine and exchange orderbook for Paxos Labs’ onchain financial infrastructure. Own pricing, settlement, integrations, and production backend systems handling real-money operations.

Description

  • Design and build core services for Transit’s RFQ orchestration engine, covering pricing, quoting, routing, inventory management, and settlement across chains and venues.
  • Design and build core services for Transit’s exchange orderbook, including the matching engine, pricing rules, order APIs, and onchain settlement.
  • Own systems across design, deployment, monitoring, and on-call operations for production systems involving real money.
  • Develop rate-aware pricing and inventory controls for assets with moving prices.
  • Integrate additional chains, venues, solver networks, and liquidity sources.
  • Build execution attribution and economics capabilities for programmatic integrator revenue sharing.
  • Work directly with smart contracts, mint and redeem facilities, and compliance enforcement.

Requirements

  • At least 6 years of experience building and operating production backend systems, with direct ownership of systems that required continuous reliability.

  • Experience building systems where correctness has financial consequences, such as exchange infrastructure, trading, or settlement systems.
  • Understanding of traditional exchange market structure, including CLOBs, batch auctions, or RFQs, across economic, incentive, and technical dimensions.
  • Experience at a market maker, exchange, or trading firm is a plus.
  • Experience with multi-chain infrastructure, particularly inventory or treasury management across chains, is a plus.
  • Previous work with tokenized assets, stablecoins, or real-world assets is a plus.
  • Understanding of onchain market structure, including AMMs, solver networks, DEX aggregators, and bridges, is a plus.
  • Ability to read Solidity and reason about contract interactions, even without writing smart contracts, is a plus.
  • Sound judgment around latency, inventory risk, and execution quality, with the ability to explain pricing decisions to commercial stakeholders.
