Own supervision of trading and order-flow reporting obligations, including CAT (all elements, including annual clock synchronization), CAIS, and TRACE, coordinating with our carrying broker and third-party reporting vendor; ensure timely and accurate compliance with SEC Rules 606 and 607 and FINRA Rule 6151, and provide supervisory review of customer account statements and trade confirmations.

Serve as the operational escalation point for trade errors, breaks, and settlement issues, coordinating investigation and resolution across Engineering, Product, Compliance, and our carrying and executing partners, assessing customer impact, and ensuring recurring issues result in appropriate process or control improvements.

Manage day-to-day operational relationships with our carrying broker, executing brokers, custodians, fund companies, and transfer agents, including escalations, service-level performance, issue resolution, and operational change management.

Partner closely with Product and Engineering on system-managed trading workflows and controls, bringing the operational and supervisory perspective to requirements, pressure-testing exceptions and edge cases, and ensuring appropriate operational readiness and oversight before launch, including post-launch operational testing to confirm controls perform as designed in production.

Build the reporting and operational visibility needed to oversee the trading function, including volumes, breaks and errors, aging exceptions, settlement performance, and control effectiveness, using those insights to identify risk, capacity constraints, and opportunities for improvement.

Have hands-on operational experience across fixed income, mutual funds, and ETFs — you know where each product breaks and why.

Have built or materially improved a trade surveillance or operational control framework, not just executed someone else’s.

Possess a strong working knowledge of the operational requirements under FINRA and SEC rules — including recordkeeping, supervision, best execution, trade reporting, and customer protection — and know how to apply them to workflows that don’t have an obvious precedent.

Communicate clearly in writing — procedures, escalations, and post-mortems that a regulator, an engineer, and an executive can each read and act on.

Be comfortable operating in ambiguity and at speed, and be willing to design the process rather than wait for one.

Bring judgment about when to automate, when to add a control, and when to accept a manual step — and be able to defend the call.

Experience standing up a new product, partner, or clearing relationships from scratch.

Comfort with SQL or working directly in internal tooling to investigate issues yourself.
