This is a hands-on senior engineering role<br>for someone who has architected such systems in a trading environment, not just<br>maintained them. You will join a collaborative team where you have a strong technical<br>voice, contributing to design and driving both the systems and the engineering<br>processes around them to a better state.</p> <p><br><span style="text-decoration: underline;"><strong>Responsibilities:</strong></span></p> <ul> <li>Contribute to and help shape the design of latency-critical distributed<br>components: market data, order routing, execution, risk, and the messaging<br>fabric between them.</li> <li>Drive systems and engineering processes to a better state: identify weaknesses,<br>propose direction, and deliver improvements end to end.</li> <li>Reason about the full latency stack across network, hardware, OS, and language<br>layers, and make deliberate, measured trade-offs.</li> <li>Deliver at scale across multiple engineers and teams: set technical direction,<br>align stakeholders, and coordinate delivery.</li> </ul> <p><span style="text-decoration: underline;"><strong>Qualifications:</strong></span></p> <ul> <li>Fluent in modern C++.</li> <li>Proven track record designing critical low-latency distributed systems in a<br>hedge fund, prop trading, or investment banking environment.</li> <li>Concrete, demonstrable understanding of what drives a latency profile across<br>the network, hardware/architecture, OS, and language layers.</li> <li>Demonstrated ability to deliver large efforts spanning multiple people and<br>teams.</li> <li>Enough hard-won production experience ("scars") to know which approaches to<br>avoid and why.</li> <li>Experience delivering performance-critical systems measured and tuned against<br>demanding latency targets.</li> <li>Exposure to exchange connectivity and market data)</li> </ul> <p>&nbsp;</p> <p><strong><span style="text-decoration: underline;">Personal Attributes:</span></strong></p> <ul> <li>Positive, pragmatic, and collaborative under pressure.</li> <li>A driver, not a passenger: you move systems and teams forward rather than<br>maintaining the status quo or talking without shipping.</li> <li>Deeply aware of trade-offs - performance vs. complexity vs. maintainability vs.<br>delivery time.</li> </ul> <p>&nbsp;</p>
