Senior Frontend Developer — Next.js / React / Pixel-Perfect UI Engineer (On-site only - Sousse)

TRVL Code builds high-impact B2C travel websites, hotel and partner dashboards, and next-generation booking interfaces used every day by travelers, hotel owners, and travel professionals. We are looking for a UI engineer, not a design executor: someone who reproduces a design reference to the pixel, and who — when the reference is incomplete, inconsistent, or not there yet — understands the business well enough to build the right thing anyway. The problem this role solves In real product work, the design is rarely finished when development starts. Some screens have a polished Figma. Some have a reference from another page. Some have a look-and-feel and a business goal, and nothing else. And some Figmas contain mistakes: a 17px gap next to a 16px one, an off-token color, a missing hover state, a flow that breaks on mobile. We have seen three failure modes, and we are hiring against all of them: The blocked developer — stops and waits every time a state, breakpoint, or component is not drawn. The photocopier — reproduces the mockup's mistakes faithfully because "that's what the Figma says." The delegator — treats a backend problem as permission to stop. The API is down, an endpoint is missing, a field is not in the payload — so the ticket sits "waiting for backend," or worse, the design gets quietly reshaped around the gap. We need the profile that does none of these: fidelity by default, judgment when it matters, always moving, and never silent.
