Full Stack Java + React Level II (Production Experience in BOTH)

IMPORTANT: Before Applying

This opportunity is ONLY for engineers who have strong professional experience with BOTH Java and React. JavaScript or TypeScript experience alone DOES NOT meet the frontend requirement.

If your background is primarily Java with limited React exposure (or vice versa), this role will not be a match.

We are specifically looking for Full Stack Engineers who build production applications across both frontend and backend. This position is ONLY for candidates currently based in Mexico and legally authorized to work in Mexico. Applications that do not meet this requirement will not move forward.
