We present parsec scale interferometric maps of HCN(1-0) and HCO$^{+}$(1-0)emission from dense gas in the star-forming region 30 Doradus, obtained usingthe Australia Telescope Compact Array. This extreme star-forming region,located in the Large Magellanic Cloud (LMC), is characterized by a very intenseultraviolet ionizing radiation field and sub-solar metallicity, both of whichare expected to impact molecular cloud structure. We detect 13 bright, denseclumps within the 30 Doradus-10 giant molecular cloud. Some of the clumps arealigned along a filamentary structure with a characteristic spacing that isconsistent with formation via the varicose fluid instability. Our analysisshows that the filament is gravitationally unstable and collapsing to formstars. There is a good correlation between HCO$^{+}$ emission in the filamentand signatures of recent star formation activity including H$_{2}$O masers andyoung stellar objects (YSOs). YSOs seem to continue along the same direction ofthe filament toward the massive compact star cluster R136 in the southwest. Wepresent detailed comparisons of clump properities (masses, linewidths, sizes)in 30Dor-10 to those in other star forming regions of the LMC (N159, N113,N105, N44). Our analysis shows that the 30Dor-10 clumps have similar mass butwider linewidths and similar HCN/HCO$^{+}$ (1-0) line ratios as clumps detectedin other LMC star-forming regions. Our results suggest that the dense moleculargas clumps in the interior of 30Dor-10 are well-shielded against the intenseionizing field that is present in the 30Doradus region.
