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

• Find opportunities to create libraries and abstractions that capture common interaction idioms, and sharpen our development practices and firm-wide approach to UI development.
• The role will provide opportunities to work in multiple parts of the stack, including front-ends, back-ends, middleware, and databases.
• The job will also involve working closely with traders and other end-users to better understand their needs.

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.)
