Senior Business Analyst, Trading Technology - 22159

We are a rapidly growing U.S.-based trading technology company that builds, hosts and manages low-latency trading infrastructure for brokers, broker-dealers and institutional trading desks. Clients license our platform rather than own it, so our relationships are long-term, technical and high-trust. We're a lean, founder-led team in Miami Beach where engineering, operations and clients work side by side and decisions get made quickly.

Today, new client onboardings, requirements and cross-team coordination run through leadership. We've outgrown that. This role exists to own those projects end to end, so that anything reaching the CEO's desk arrives about 80% done.

You'll be the senior analyst that clients and engineers both trust. Roughly 70% of the job is communication: leading onboardings, gathering requirements and coordinating engineering, operations and compliance. The other 30% is hands-on technical work: digging into data, prototyping tools and learning the platform well enough to challenge engineers. As the analyst team grows, you'll lead it.

Requirements & Process Design

• →Turn business needs into clear requirements, user stories and process models (BPMN/UML)
• →Learn the stack (FIX, APIs, Smart Order Routing) and explain it in plain language to clients and internal teams
• →Partner with compliance so regulatory requirements are built into specs from the start
• →Maintain documentation and runbooks the team can rely on

You are: equally credible on a client call and in a room full of engineers. You bring leadership answers, not open questions. You're organized enough to keep five onboardings moving at once and technical enough to pull the data yourself when something looks off. You like owning outcomes, and you'd rather build a small tool than repeat a manual task twice.
