Les missions du poste
Flowdesk's mission is to build a global financial institution for digital assets, one designed from the ground up for market integrity and efficiency.
To achieve this in a rapidly evolving market, we apply a disciplined, first-principles approach to everything we do. This approach is embedded in our core services, from institutional liquidity provision, trading solutions, OTC execution to our comprehensive treasury management offerings. This is how we cut through the noise and build robust and scalable systems across all our business lines.
We seek individuals who are driven by this systematic approach. Joining Flowdesk means you will be a key contributor in building and scaling a more transparent and efficient financial markets infrastructure.
Given our rapid growth, we've also launched our Early Talent Program, designed to attract and develop high-potential students through internship experiences. This program aims to build a strong pipeline of future full-time employees who are already aligned with our culture and expectations.
You'll join a Full-Stack team building the tech powering our OTC product, most notably working on the web applications used by traders. We ship advanced React/TypeScript apps endtoend from clean form flows to scalable components while evolving our UI library and Flowdesk's design system.
Role
- Build and ship front-end features for our OTC product, using React and TypeScript, owning tasks end-to-end (specs, UI, testing, release).
- Contribute to our UI library and Flowdesk's design system, create and maintain reusable components, work with UI/UX designers, resolve design mismatches, and ensure consistency with our graphic charter.
- Tackle foundational front-end work (performance, accessibility, testing, developer experience) while iterating quickly on simple product interfaces (forms, validations, state management).
- Collaborate with product, design, and engineering to scope, implement, and improve user-facing features; explore new approaches and share learnings.
Our stack Back-end, Typescript, NodeJS, Rust, GCP, Kubernetes, Docker. And in the Front-end, React, TypeScript, Tailwind, styled-components, AG-Grid, Tailwind
