What are the responsibilities and job description for the Senior Research Associate, Chemical Biology position at Flagship Pioneering?
What if… you could pioneer a new approach to designing life’s most essential molecules?
FL116, backed by Flagship Pioneering, is an early-stage biotechnology company transforming the way biomolecules are synthesized. Our innovative platform has the potential to transform how critical research, diagnostic, and therapeutic molecules are manufactured. We are seeking passionate problem solvers ready to make a profound impact on biotechnology and therapeutic innovation.
Position Summary
We are seeking a motivated, detail-oriented, and intellectually curious Research Associate or Senior Research Associate to join our Chemical Biology team. This role is centered on applying chemistry to solve complex biological problems, interrogating and controlling enzyme-driven biomolecular synthesis through a mechanistic and molecular lens.
You will execute high-throughput experiments to probe enzyme–substrate interactions, characterize biomolecule products, and contribute to the development of robust, scalable assays that power our platform. The ideal candidate appreciates the dynamic chemical nature of biological systems and is excited to manipulate and measure biology at the molecular level.
This is an exciting opportunity to build deep expertise at the interface of chemistry and biology within a fast-paced, collaborative startup environment. You are a hands-on experimentalist who thrives in execution-focused, pipeline-driven work and is eager to grow alongside a rapidly evolving technology platform.
Key Responsibilities
Innovative Pioneer: You are excited by the opportunity to explore new scientific frontiers and apply chemical thinking to unlock biological complexity.
Collaborative Contributor: You work effectively across teams, communicate clearly, and value shared success in a highly interdisciplinary environment.
Inventive Problem Solver: You approach challenges with curiosity and creativity, using first-principles thinking to develop elegant experimental solutions.
Mission-Driven Individual: You are motivated by the opportunity to fundamentally change how biomolecules are synthesized and to impact human health and biotechnology.
Motivated Learner & Emerging Professional: You are eager to deepen your expertise in chemical biology, take ownership of your work, and grow into a highly capable scientist within a startup environment.
Values and Behaviors:
Flagship is an experiment in institutional, entrepreneurial, and innovation practiced in the context of a small company with an insurgent mindset. We are seeking individuals with an entrepreneurial spirit, strong communication skills, and comfort in working in and contributing to a dynamic and cross-functional team environment.
At Flagship, we recognize there is no perfect candidate. If you have some of the experience listed above but not all, we encourage you to apply anyway. Experience comes in many forms, skills are transferable, and passion goes a long way. We are dedicated to building diverse and inclusive teams and look forward to learning more about your unique background. The level of the role will be commensurate with the education and years of experience of the identified candidates.
Flagship Pioneering and our ecosystem companies are 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.
Recruitment & Staffing Agencies: Flagship Pioneering and its affiliated Flagship Lab companies (collectively, “FSP”) do not accept unsolicited resumes from any source other than candidates. The submission of unsolicited resumes by recruitment or staffing agencies to FSP or its employees is strictly prohibited unless contacted directly by Flagship Pioneering’s internal Talent Acquisition team. Any resume submitted by an agency in the absence of a signed agreement will automatically become the property of FSP, and FSP will not owe any referral or other fees with respect thereto.
The salary range for this role is $81,000 - $107,250. Compensation for the role will depend on a number of factors, including a candidate’s qualifications, skills, competencies, and experience. FL116 currently offers healthcare coverage, annual incentive program, retirement benefits and a broad range of other benefits. Compensation and benefits information is based on FL116's good faith estimate as of the date of publication and may be modified in the future.
