Scientist III, Chemistry

Thermo Fisher Scientific•Pleasanton, CA

1d•Onsite

About The Position

The Scientist III will join the Organic and Oligo Chemistry team, which designs and develops novel dyes and highly functionalized oligonucleotide constructs for R&D programs and new product development within the Genetic Sciences Division. The role focuses on designing, synthesizing, purifying, characterizing, and evaluating modified oligonucleotide constructs for real-time PCR and other molecular biology workflows. It combines oligonucleotide chemistry expertise with hands-on PCR experimentation to investigate how oligonucleotide design and chemical modifications affect assay performance. The Scientist independently designs and executes experiments, solves complex technical problems, interprets data, and makes scientific recommendations to advance R&D and new product introduction programs. The role works closely with scientists in chemistry, PCR, Human Identification (HID), and manufacturing. It is fully onsite at the Pleasanton, California facility; relocation assistance is not provided.

Requirements

Bachelor’s degree in Chemistry, Biochemistry, or a related scientific discipline and 3–5 years of relevant laboratory or R&D experience; alternatively, a Master’s degree in Chemistry, Biochemistry, or a related scientific discipline with relevant graduate research and/or professional R&D experience.
Hands-on laboratory experience in oligonucleotide chemistry, biochemistry, molecular biology, or a closely related area.
Hands-on experience with oligonucleotide synthesis, purification, modification, conjugation, and/or characterization.
Experience with analytical and purification techniques such as HPLC, LC-MS, or related methods.
Hands-on experience operating real-time PCR instruments and performing PCR or qPCR experiments.
Experience analyzing and interpreting real-time PCR amplification data.
Ability to independently design and execute experiments, analyze complex data, troubleshoot experimental challenges, and develop scientifically sound conclusions and recommendations.
Strong scientific problem-solving and critical-thinking skills, including the ability to investigate root causes and develop experimental approaches to technical problems.
Ability to manage multiple experimental activities and priorities and contribute to R&D project objectives.
Ability to maintain accurate laboratory documentation and prepare technical reports and presentations.
Strong written and verbal communication skills, including the ability to communicate technical results and recommendations to multidisciplinary teams.
