Overview

Citadel Securities seeks a hands-on technical leader to shape the next generation of data visualization tools behind its client-facing products. The work sits where software engineering, visualization, product design, and human-computer interaction meet, and you own both the applications and the reusable frameworks beneath them. Early focus lands on a small set of distinctive, high-quality client apps, with a mandate to grow that work into a firm-wide standard. Product and engineering partners lean on you to weigh usability, performance, and maintainability in the same conversation.

What You'll Do6

Build the core visualization platform that powers client-facing analytics and experiences across the firm.
Create reusable visualization frameworks, design systems, and tooling so other teams ship high-quality data products faster.
Work with Sales, business leaders, engineering, product management, and design to turn tangled business problems into clear technical solutions.
Vet emerging technologies and fold the useful ones into the visualization platform.
Push new approaches to how market, trading, and client data get explored, understood, and communicated.
Lead through hands-on development, design reviews, and mentoring.

Requirements8

Track record of strong technical execution paired with sharp visual judgment.
Substantial experience contributing to sophisticated data visualization applications, platforms, frameworks, or developer tooling.
Depth with modern visualization technologies such as D3.js, Observable, WebGL, Three.js, Vega, React, TypeScript, and Python.
Solid grounding in typography, layout, color, visual hierarchy, interaction design, and information architecture.
Clear grasp of how people consume and interpret complex information.
Experience working across engineering, design, and product organizations.
Strong communication and stakeholder management skills.
Bachelor's degree or higher in computer science, design, human-computer interaction, cognitive science, engineering, or a related field.

Who Should Apply

A principal-level builder who pairs engineering rigor with real design sense and wants ownership of a visualization platform from first app to firm-wide standard. Candidates with deep D3.js or WebGL work and a portfolio of complex data products fit best.

Salary Insight

The base salary range runs $175,000 to $350,000, and the person who fills the role also qualifies for a discretionary incentive compensation program plus benefits covering medical and life insurance, retirement and tax-free savings plans, and other healthcare programs. A spread that wide at a market maker points to principal-level scope, so the final offer tracks experience and demonstrated impact.
