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
