React Developer – Build the Future of Professional Platforms

Ditto is building the next generation of recruitment and professional platforms, used by millions each month. We help staffing firms and hiring teams find, manage, and place top candidates with smart, beautiful software. Now, we’re on a mission to launch something new. Big. Stealthy. And you're invited.

We’re looking for a React Developer to help craft the interfaces behind this new product - something slick, responsive, and deeply human. If you want your code to have an impact right away , and if you love pushing front-end boundaries while still keeping it clean, read on.

What You’ll Do

• Build and refine modern, responsive UIs that people actually enjoy using

• Work closely with our UX/UI and product teams to create smooth, fast, intuitive experiences

• Help shape the direction of our front-end stack and overall product architecture

• Be hands-on with REST APIs, component libraries, and full-stack flow

• Advocate for quality, performance, and reusability in everything you ship

• Write clean, well-documented code that can scale with a fast-growing product

Must-haves:

• React (obviously)

• Next.js

• RESTful APIs and JSON

• Node.js + NPM

• HTML, CSS, JavaScript (solid SPA experience)

• Git (merge conflicts don’t scare you)

• Experience building real-world productized software

Bonus points if you’ve touched:

• Figma / design systems

• Cursor

• Webpack

• Terminal / Bash scripting

• Caching & performance tuning

• OOP principles and full-stack awareness

• Documentation that doesn’t suck

Why Join Ditto?

• You’ll be early. As in ground-floor. We're launching a major stealth product - millions of users on day one.

• You’ll have a voice. No layers of managers. Just builders.

• You’ll move fast. But not carelessly. We ship, we test, we learn.

• You’ll work on stuff that matters. We’re reimagining how people present themselves online, connect with others, and build professional identity in a noisy digital world.

• You’ll be part of something fun. We build cool shit, not corporate fluff.

If this sounds like the kind of place you’d thrive in - where every commit, conversation, and decision counts - then let’s chat.
