The Role

We're looking for a Co-Op to join our Proteomics team and contribute to the development of Etiome's Integromyx and Perturb-seq platforms. You'll get hands-on experience across the full mass spectrometry-based proteomics workflows, from cell culture and sample preparation through LC-MS/MS acquisition on Orbitrap systems, including exposure to chemoproteomics experiments that sit at the intersection of chemistry and biology.

You'll work as part of a cross-functional team where your contributions matter from day one. We're looking for someone who is curious, detail-oriented, and eager to develop their skills alongside a team building something new.

Key Responsibilities

• Set up, maintain, and operate Orbitrap mass spectrometry and associated liquid chromatography systems
• Maintain mammalian cell cultures; prepare growth media and expand cells for experiment setup
• Execute proteomics sample preparation workflows including protein extraction, fractionation, and LC-MS analysis
• Use laboratory automation for sample preparation and processing
• Contribute to proteomics and chemoproteomics experiments and support data analysis
• Present findings in team and cross-functional meetings; maintain meticulous electronic lab notebook records

Basic Qualifications

• Currently enrolled in a B.S. or M.S. program in Chemistry, Chemical Biology, Biochemistry, or a related field
• Coursework or hands-on laboratory experience in chemical biology, liquid chromatography, or mass spectrometry

Preferred Qualifications

• Familiarity with analytical techniques with a focus on mass spectrometry, especially Thermo Fisher instrumentation
• Experience with liquid chromatography sample preparation and purification
• Familiarity with R, Python, or strong interest in learning informatics tools
• Interest in lab automation instrumentation
• Prior experience with mammalian cell culture

What We Offer

• Build alongside founders. You’ll work inside the same hypothesis-driven process Flagship uses to conceive and launch first-in-category companies.
• This can be the start of a longer story. Strong co-ops are considered for future opportunities across Flagship and its portfolio companies, not just for this one role.
• Work alongside people who left the safe path. Your colleagues are scientists, engineers, and operators who chose to build something new rather than join something already established.
• Take on real ownership. You're contributing to ventures that are still being defined. Your work can shape real decisions, not just support them.
• Be paid like the contributor you are. Compensation reflects the real work you take on.

Flagship Pioneering is committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity or Veteran status.

Retirement benefits may be available after completing a set number of hours. Compensation and benefits information is based on Etiome, Inc.'s good faith estimate as of the date of publication and may be modified in the future.
