Summary:

What We’re Building (and Why It’s Kind of a Big Deal)

We’re a small team inside TransPerfect building a massive internal platform—a low-code application builder that’s powering how our entire company operates. It’s ambitious. It’s complex. It’s not “done.” And that’s exactly why it’s fun.

 

Think:

  • Drag-and-drop UI builder

  • Highly dynamic, data-driven interfaces

  • Enterprise-scale… without enterprise-level red tape

 

We operate more like a startup embedded inside a global company, which means we move fast, figure things out as we go, and need people who are excited to build something real from the ground up.

 

What You’ll Actually Be Doing

You won’t just “work on UI.” You’ll help define how this whole thing works.

  • Build and evolve a drag-and-drop app builder used across the company

  • Collaborate and shape frontend architecture decisions (React / Next.js)

  • Implement highly interactive, state-heavy UIs

  • Create component systems that non-developers can configure and use

  • Balance performance, usability, and flexibility in a complex environment

  • Partner closely with product and design (who have opinions) and engineering (who have different opinions)

 

The Kind of Engineer This Role Needs

We’re not looking for someone who needs perfect specs and clean workflows.

We’re looking for someone who:

  • Is comfortable when things are a little messy

  • Can figure things out without a playbook

  • Has strong eye for design and knows when to pivot

  • Can think like both a developer and a designer

  • Doesn’t panic when priorities shift or structure evolves

 

If you’ve worked in a perfectly polished, process-heavy dev org: this will feel different.

If you’ve ever said “this could be built way better if we just…”:  this is your playground.

Core Technical Stuff (Yes, This Still Matters)

You’ll need to be strong here, we’re building something non-trivial.

  • React / Next.js (deep experience, not surface-level)

  • Advanced state management (handling complex, nested, high-volume UI state)

  • TypeScript (strict mode)—you’re comfortable modeling complex systems

  • Component architecture—you’ve built systems, not just screens

  • Styling systems (we use a mix of MUI + Tailwind… yes, really, so experience in both is preferred)

  • Performance tuning (keeping things smooth even when they shouldn’t be)

Bonus points:

  • Experience with low-code/no-code tools

  • Thinking in JSON schemas / UI-as-data

  • Building drag-and-drop interfaces

Design Mindset (This Is Big for Us)

We need engineers who care about UX, not just functionality.

  • You can design dense interfaces that still feel usable

  • You think about how users actually interact with systems

  • You understand tradeoffs between flexibility and clarity

  • You’re comfortable shaping UX—not just implementing it

 

What It’s Like Working Here

Let’s be real:

  • We’re building something big with a small team

  • The structure isn’t perfect

  • Priorities can shift

  • We’re figuring some things out as we go

But also:

  • You’ll have real ownership

  • Your decisions will
