Senior Scientist, Protein Engineering

Job Description

The Protein Engineering group in Rahway, New Jersey is seeking a Senior Scientist to expand our capabilities to design and engineer proteins with novel functions. The mission of the group is to engineer enzymes for use as biocatalysts to synthesize APIs and to engineer proteins, peptides, and/or nucleic acids as therapeutics and vaccines. We view protein engineering as a key enabling technology in modern drug discovery and development. We leverage computational modeling, advanced automation, and high-throughput screening to engineer novel proteins. We are committed to developing new methodologies and technologies that enhance protein engineering and improve human health. The group collaborates broadly within our Company, with academic leaders, and with industry partners to expand and accelerate the impact of protein engineering on human health.

In this role, the incumbent will contribute directly to the invention of novel proteins by guiding gene acquisition, designing and building high-quality DNA libraries, expressing large protein libraries, developing assays, and/or characterizing libraries using high-throughput screens and selections. As part of project teams, they will collaborate across groups to develop novel solutions that solve complex problems. As a project leader, they will guide engineering teams to develop engineering strategies, choose which engineered proteins to select as leads, and deliver biocatalysts and/or biotherapeutics with improved functions and properties. They will give scientific presentations internally and externally, contribute to the overall strategy and direction of the group, and develop novel protein engineering technologies. The successful candidate will join a diverse group of innovative scientists that are driving the next revolution in bioengineering.

  • Demonstrated ability to work within a collaborative multi-disciplinary team environment.
  • Excellent communication and organizational skills.



Preferred Experience and Skills:

  • Experience engineering one of the following: novel biocatalysts, biosynthetic pathways, amino acid/peptide modifying enzymes, protein assemblies, and/or de novo proteins.
  • Experience with multiple strategies to create genetic diversity, multiple host organisms and/or cell free expression systems, and/or multiple high-throughput screening/selection methods.
  • Familiarity with one or more of the following areas are highly desired: next-generation sequencing, computational protein design, machine learning, microfluidics, and/or automation.
  • Experience with reproducible data analysis, for example using Python or R.



We are a research-driven biopharmaceutical company. Our mission is built on the simple premise that if we "follow the science" that great medicines can make a significant impact to our world.
