About HotSpot Therapeutics, Inc.

Within every human cell, nature has engineered finely-tuned control mechanisms to correct imbalances caused by stress and disease and promote healing.  At HotSpot Therapeutics, nature is inspiring us to create a wave of new medicines.

Through a proprietary technology platform, we are uncovering privileged allosteric sites used by nature to control proteins – called regulatory hotspots– that can be exploited through small molecule drug discovery. Regulatory hotspots are allowing sought-after targets to be drugged for the first time while delivering molecules with exquisite selectivity and attractive drug-like properties. HotSpot is supported by a syndicate of leading healthcare investors based in the US and Europe.

You will be joining a seasoned team of drug hunters with an excellent track record in drug discovery. As a HotSpotter, you are comfortable thinking outside the box and breaking convention. You are curious about the world and contribute beyond your precise role description. You are action orientated and extraordinary at getting things done. You communicate openly with your colleagues, and you hate office politics.
