Providing real value for our customers today while shaping the future of money.About the RoleWe're looking for a Senior Software Engineer to join our Trading & Liquidity squad and build the systems that power the heart of Quidax.This is a hands-on engineering role for someone who enjoys solving hard backend problems where reliability, performance, and correctness matter. You'll build and operate Java services that power trading, pricing, liquidity, order execution, settlement, and exchange integrations. These are systems where milliseconds matter, failures have financial impact, and every design decision counts. You’ll thrive here if you’ve built transaction-heavy financial systems before, enjoy thinking deeply about distributed systems and concurrency, and love taking ownership of critical services from design through production.What You’ll Be OwningBuild & Own Critical Trading Services Design, build, deploy, and operate scalable Java services powering trading, pricing, execution, and liquidity. Own critical backend services end to end, from architecture and implementation to production support and continuous improvement. Build systems that remain reliable under heavy traffic, partial failures, and changing market conditions. Trading, Execution & Liquidity Develop and improve order management, execution, pricing, market data, and liquidity management capabilities. Build and maintain integrations with exchanges, liquidity providers, custodians, payment providers, and other external platforms. Improve execution quality through better pricing accuracy, spreads, fill rates, liquidity availability, and reduced slippage. Build Reliable Financial Systems Design reliable order lifecycles covering validation, routing, execution, settlement, reconciliation, cancellations, retries, and recovery. Ensure financial correctness across balances, positions, fees, and settlements through precision, idempotency, consistency, and auditability. Build distributed systems that behave correctly under concurrency, retries, duplicate events, and eventual consistency. Improve Performance & Reliability Continuously improve system performance, resilience, observability, throughput, and operational readiness. Investigate production incidents, perform root cause analysis, and implement preventive improvements. Build testing strategies covering unit, integration, contract, performance, and resilience testing. Raise the Engineering Bar Participate in architecture and technical design decisions across the Trading & Liquidity squad. Review code, mentor engineers, and help raise engineering standards across the team. Collaborate closely with Product, Platform, QA, Security, Compliance, Risk, Finance, and Operations to deliver reliable financial systems. Biggest Challenges You’ll TackleThis isn't a role where you're simply building APIs. You'll be solving engineering problems where correctness, speed, and resilience all matter at the same time. Some of the challenges you'll tackle include: Building systems that continue operating reliably during volatile market conditions. Designing distributed systems that remain consistent despite failures, retries, and duplicate events. Improving latency and execution quality without sacrificing correctness. Managing concurrency, race conditions, transaction boundaries, and eventual consistency across critical financial systems. Building exchange and liquidity-provider integrations that remain resilient when external systems fail. Delivering systems where balances, settlements, and financial records remain accurate and fully auditable. What We're Looking ForWe're looking for...
