  Systems combining superconductors with topological insulators offer a
platform for the study of Majorana bound states and a possible route to realize
fault tolerant topological quantum computation. Among the systems being
considered in this field, monolayers of tungsten ditelluride ($\mathrm{WTe_2}$)
have a rare combination of properties. Notably, it has been demonstrated to be
a Quantum Spin Hall Insulator (QSHI) and can easily be gated into a
superconducting state. We report measurements on gate-defined Josephson
weak-link devices fabricated using monolayer $\mathrm{WTe_2}$. It is found that
consideration of the two dimensional superconducting leads are critical in the
interpretation of magnetic interference in the resulting junctions. The
reported fabrication procedures suggest a facile way to produce further devices
from this technically challenging material and the results mark the first step
toward realizing versatile all-in-one topological Josephson weak-links using
monolayer $\mathrm{WTe_2}$.
