Job description

Overview

We’re building for expert users, which means we want to maintain a high UX bar, and at the same time create tools that are flexible and powerful enough to satisfy the needs of deeply engaged users.

Beyond working on the individual tools, we want someone who can find opportunities to create libraries and abstractions that capture common interaction idioms, and to sharpen our development practices and firm-wide approach to UI development.

Responsibilities

• Work across multiple parts of the stack, including front-ends, back-ends, middleware, and databases.
• Collaborate with traders and other end-users to understand their needs and translate insights into usable, scalable UI solutions.

Qualifications

• An interest in and appreciation of typed functional programming as an approach to UI construction. Experience with languages like Elm, ReasonML, Purescript, and Typescript is a plus (we don’t expect experience in OCaml in particular).
