Role Description We're looking for a Staff Engineer to own a critical domain within our market making platform — pricing engine, order management, data ingestion, or PnL infrastructure — and take end-to-end accountability for its correctness, performance, and reliability under live trading conditions. This is a hands-on, high-ownership role. You'll work alongside our Senior Staff and senior engineers to build the systems that keep our markets liquid and our book healthy at peak volume. Real money is on the line every time our system quotes a price — the work is technically demanding, commercially consequential, and directly visible in daily P&L snapshots the whole team sees. You won't be handed a spec. You'll be expected to understand the trading business well enough to write one, and to care about outcomes beyond just shipping the feature. Responsibilities - Own a major domain within the market making pipeline — pricing engine, order management, real-time data ingestion, or PnL/risk infrastructure — driving design, implementation, and ongoing operational reliability. - Build and maintain systems that process high-throughput, low-latency event streams: market data, fixture updates, pricing feeds, and order lifecycle events across exchanges. - Partner with our Senior Staff engineer and trading team on cross-domain technical decisions — contributing grounded domain expertise while maintaining the integrity of the broader platform architecture. - Contribute to the exchange abstraction layer being built for our in-house exchange, helping define the APIs and integration patterns that will connect us to new venues beyond CDNA. - Build and improve internal Trading UI tooling — dashboards, kill switches, position monitors, and manual intervention surfaces — that our traders depend on for real-time market management during live events. - Diagnose and respond to production issues in a live trading environment: understand whether a bad P&L day came from pricing latency, a strategy misfire, a mapping error, or an adverse selection pattern — then fix it durably. - Proactively identify performance bottlenecks and technical risk within your domain before they affect trading operations or our hold rate. - Contribute to team-level engineering standards — design docs, code and architecture reviews, and patterns that hold up as we expand to new sports, market types, and exchange venues. - Develop genuine fluency in our trading economics: understand spread logic, adverse selection, inventory risk, and where we make and lose money — and use that context to prioritize what to build and improve. Qualifications - 7+ years building scalable, fault-tolerant distributed systems in production environments. - Strong hands-on proficiency with Java, Kafka, Redis, Kubernetes, AWS, and Postgres. - Deep experience with event-driven architecture and async messaging — you've designed and debugged consumer group strategies, partition schemes, and delivery guarantees under real production constraints. - Demonstrated end-to-end domain ownership: you've designed, built, operated, and improved systems — not just delivered features. - Strong performance instincts — you think carefully about latency, throughput, and data pipeline efficiency, and you know how to measure what matters. - Clear, direct communicator — you can write a crisp design doc, explain a production failure to a trader, and debate an architectural trade-off with a principal engineer. - High risk tolerance for ambiguity and speed — you're comfortable deploying daily, working without a release train, and making good decisions when the spec is still being written. Preferred - 3+ years building systems where latency, throughput, and cost efficiency are in constant tension. - Experience in real-time trading, financial infrastructure, market data platforms, or prediction markets. - Familiarity with FIX protocol or exchange connectivity patterns. - Working knowledge of quantitative concepts — pricing models, spread optimization, inventory management, or adverse selection — even if you've come at them from the engineering side. Salary Range $180,500 — $237,500 USD By submitting your application, you agree to our terms of service and acknowledge you have read our Candidate Privacy Policy.
