Company Background
Pillar Therapeutics ( Pillar ) is a pioneering biotechnology company focused on next generation oligo-based modalities targeting tissues beyond the liver, muscle, and kidney. We are building a platform to deliver oligos with high precision to previously untargeted cells, while focused on “undruggable” genes, alone or in combination with previously validated targets. Many of our targets carry 'pipeline-in-a-drug' potential: a single gene or protein with meaningful biological effects across multiple disease areas. Headquartered in Cambridge, Massachusetts, Pillar was incubated in RA Capital’s venture group (Raven) and is led by an experienced CEO. After a robust incubation and vetting process, Pillar was launched and funded by RA Capital.
Pillar’s therapeutic areas of interest lie outside commonly targeted cells and tissues, and represent multi-billion-dollar markets that are continuing to grow as the population ages. Our initial focus is creating transformational therapies to treat diseases, but given the platform potential, we have longer-term ambitions to address healthy aging. These targets are backed by strong biological and genetic evidence but have historically resisted small molecule and biologic approaches. Pillar, operating in stealth mode, is moving quickly to address multiple disease indications at scale and with significant market potential.
Opportunity
We are in the discovery stage and will invest heavily in its emerging platform for oligonucleotide delivery. Our disease focus offers strong translatability from animal models to humans, which provides a potentially rapid and efficient path to the clinic. Given our recent funding and commitment to building a first-in-class platform with clear therapeutic targets and indications, we are recruiting a Principal Scientist, Analytical Chemistry. This individual will be responsible for developing analytical methods and characterizing our oligonucleotide conjugates for our targeted delivery platform.
The Position
The Principal Scientist, Analytical Chemistry will report directly to the Director of Oligonucleotide and Conjugation Chemistry and will interface frequently with members of the delivery group and cross-functional teams to advance oligonucleotide therapeutic programs. This individual will help define and execute the strategy to analyze oligonucleotides and conjugates in an efficient and timely manner. As a lab-based role, this person will assist in the implementation and use of scientific and analytical equipment to yield high-quality oligonucleotide and oligonucleotide-conjugate materials.
Specific responsibilities for the Principal Scientist, Analytical Chemistry include:
Define and implement reproducible analytical protocols to characterize oligonucleotides for biological evaluation in our targeted delivery platform
Develop and implement QC methods to determine purity, composition, and concentration of oligonucleotides and conjugates using a toolbox of analytical methods (HPLC, MS, (bio)analytical assays, etc.)
Develop and implement analytical methods (e.g., MS) to determine drug-to-conjugate ratios of antibody-oligonucleotide conjugates
Develop and implement analytical methods to determine in vitro stability (e.g., serum stability) of oligonucleotides and conjugates
In conjunction with the biology group, assist in development and implementation of analytical methods to determine pharmacokinetics and distribution of oligonucleotides and conjugates in vivo
Assist in internal lab build, procuring and ut…
