About the Role
We are looking for a Frontend Developer to join our New York development team. You will work alongside a lead developer within the Marketing team, and collaborate daily with a Product Owner, a UI/UX designer, and report directly to the CMO. The team is small and tight-knit — you’ll have real ownership over your work and a voice in design discussions and feature conversations.
Your work will span two main areas: Witbe’s commercial website and a suite of internal web applications used across the company. The NY dev team covers multiple projects, so expect variety in your day-to-day and the opportunity to work across different codebases and technologies.
Commercial Website
Witbe’s public-facing website was rebuilt from the ground up in 2025 with a modern stack: Astro 5 for SSG, vanilla TypeScript, and Strapi 5 as a headless CMS. Your work here will include:
Building features and refining the design based on UI/UX mockups.
Crafting new pages, sections, and components driven by product evolutions and marketing needs, keeping the website up to date and relevant.
Restructuring Strapi content models, creating reusable editor components, and developing Strapi plugins where needed. On the Astro side, formatting and reshaping data coming from the CMS to work around its limitations, and eventually migrating static parts of the site to become CMS-driven.
Handling static content updates directly in the Astro codebase.
Optimizing for SEO, performance, and accessibility.
Being open to changing direction as priorities shift and pages may be reworked or replaced.
Internal Applications
The team develops and maintains several internal React applications (TypeScript, Styled Components, TanStack Query, Redux Toolkit) used by Sales, Production, and Engineering teams:
Production and manufacturing: Witbox production workflows, as well as a cloud provisioning control plane for managing and monitoring Witbe's cloud-hosted infrastructure, with real-time updates and topology visualization.
User and organization management: a central portal serving as the hub of the Witbe ecosystem, project management, user settings, and admin tools.
While working on internal apps, you may also be involved in back-end tasks, so full-stack experience or willingness to learn will be a plus.
Documentation Platform
You may also contribute to Witbe’s documentation platform, built with Astro Starlight. It serves both clients and internal teams, and will eventually be embedded within some Witbe products. The team is exploring AI-assisted search and retrieval features for the future
