Research Associate, Flow Cytometry

Ohana is seeking a skilled, motivated Research Associate specializing in flow cytometry.

Flow cytometry plays a critical role in all of our research programs, from contraception to fertility, and you will be the point person for all of it!  You will have the opportunity to quickly take on responsibility and independence, and use your flow cytometry expertise to the fullest.

Ohana’s sperm biology platform is built around a deep understanding of single-cell heterogeneity in sperm. Within the average 100 million sperm per ejaculate, significant variations exist both at the molecular and functional levels. Flow cytometry is the technology we use to detect and quantify this heterogeneity—but sperm poses many unique challenges. You’ll keep our instruments running at full capacity, creatively problem-solve, and help develop new ideas and assays.

You’ll also have opportunities to take on research projects outside of flow cytometry. Working both independently and as part of a highly collaborative team, you’ll design, plan and execute experiments to investigate sperm heterogeneity and function.

Company Overview

Ohana is an early-stage biotechnology company founded in 2015 by Flagship Pioneering, which has founded over 40+ breakthrough companies, including Seres Therapeutics, Agios, Rubius, Moderna, Editas, Denali and Codiak, since 2000.

At Ohana Biosciences, we are pioneering a new frontier in reproductive medicine. Built upon a world-leading understanding of sperm biology, Ohana has created a best-in-class proprietary platform with field-defining applications including:

  • Preventing inherited disease;

  • Delivering a highly effective, safe, reversible, non-hormonal contraceptive; and

  • Treating male infertility, traditionally ignored but responsible for half of infertility issues.

Our mission is to provide men and women the freedom to decide when to have a family and empower them to have healthy children. Join us in transforming the field of reproductive medicine and creating technologies with the power to benefit our customers and transform the lives of their patients.

What You’ll Do

  • Collaborate with programs and teams across all of R&D to fulfill their flow cytometry needs

  • Maintain and optimize our two instruments: an analytical flow cytometer (Cytoflex) and a cell sorter (Moflo Astrios)

  • Train new users and advise on experimental design

  • Develop new flow cytometry protocols, assays, and capabilities

  • Perform cell sorts with our Moflo Astrios

  • Prepare samples for flow cytometry analysis, analyze data, process samples after sorting

  • Participate in non-flow cytometry-based research projects: design, plan and execute experiments, using molecular biology and biochemistry techniques

What Skills You’ll Bring

  • Bachelor’s or Master’s degree in a biological science or related science field

  • 1+ years of experience running flow cytometry instruments

    • Note: we will provide training on our specific instruments (Cytoflex and Astrios)

  • Experience preparing samples for flow cytometry and analyzing flow data

  • Experience with basic molecular biology and biochemistry techniques such as: immunofluorescence, Western Blot, ELISA, DNA extraction, or PCR

  • Demonstrated ability to work both independently and as part of a highly collaborative team

  • Flexibility and ability to creatively problem solve in a changing, fast-paced research environment

What We’ll Offer You

  • A dynamic early-stage work environment, with encouragement at all levels to be creative regarding new projects and product ideas

  • Participation in projects ranging from cutting-edge basic research to product development

  • Generous paid family leave

  • Opportunities for career development and advancement, including trainings, classes, and conferences

  • Daily on-site snacks, coffee, and sparkling water, and monthly catered lunches

  • Comprehensive, competitive healthcare (PPO) and dental coverage through Blue Cross Blue Shield, and vision coverage through VSP

  • 15 vacation days and 10 company-paid holidays

  • 401k retirement plan, disability and life insurance

Our Culture

We are a collaborative, innovative, and enthusiastic team of 30+ employees and growing. We are highly interdisciplinary, with most scientists participating in a wide range of research projects, and creativity encouraged at all levels regarding new projects and product ideas. Our work defines the cutting edge of basic research in sperm biology.

We are located in Cambridge near the heart of America’s biotech hub. We offer an open workspace just a few blocks from the Charles River, fun perks like on-site snacks, monthly catered lunches, off-site get-togethers and other social opportunities, comprehensive, competitive health care, and more.

If you are collaborative, hard-working, and excited by the opportunity to pursue transformational science in the field of reproductive medicine, we want to talk to you.
