About Alltrna

Alltrna is the world’s first tRNA platform company to decipher tRNA biology and pioneer tRNA therapeutics to treat thousands of diseases. Alltrna unlocks tRNA biology to correct disease. The company's platform incorporates AI/ML tools to learn the tRNA language and deliver diverse programmable molecules with broad therapeutic potential. Alltrna has an unprecedented opportunity to advance a single tRNA medicine to unify treatment across a wide range of diseases with the same underlying genetic mutation. Alltrna was founded in 2018 by Flagship Pioneering. For more info, visit www.alltrna.com.

About The Role 

Come join a creative and collaborative team of scientists dedicated to leveraging emerging insights in RNA biology to develop novel classes of oligonucleotide therapeutics to treat human diseases and improve human health. In this role you will play a critical/vital role in DMPK Group and work closely with internal partners and external collaborators to enable identification of multiple drug candidates for human clinical studies. Please apply if you feel that you can contribute to growing our team and advance our mission.

As an early member of a privately held, well-funded, early-stage platform biotechnology company, you will have significant influence on the platform development, drug discovery and development, and translation into the clinic along with the opportunity to grow as the company continues to expand. You will also benefit from opportunities to engage with the broader Flagship Pioneering ecosystem. The ideal candidate will perform lab-based activities focusing on in vitro ADME projects (e.g. metabolic stability) and other in vitro assays to support the characterization of molecules from discovery through to early development. The position will allow for regular interaction with DMPK, pharmacology and discovery project teams. Another focus of this position will be in the area of study management including all aspects of sample management/coordination.

Core Responsibilities


  • Responsible for conducting routine ADME assays for discovery and development stage compounds
  • Participate in experimental design, performing experiments and data analysis/interpretation, troubleshooting
  • Development of novel assays to address mechanistic ADME-related questions for RNA therapeutics
  • Contribute to  in vivo samples processing for various assays, including tissue homogenization in collaboration with other groups and functions according to SOPs
  • May perform nucleic acid extraction as well as DNA/RNA/protein quantification of experimental samples.

Study Management Support:

  • Communicate with internal and external partners for the successful initiation, conduct and completion of all DMPK and pharmacology studies.
  • Responsible for authoring and seeking review/ approval of protocols related to sample management capabilities
  • Receive, reconcile and store/forward the incoming biological and test article samples.
  • Maintain both  physical and electronic records for sample storage, location and disposition.
  • Maintain and track the required paperwork, documentation and agreements for all in vivo studies

Qualifications and Skills

  • Qualified candidate should have at least a BS/BA preferably in any STEM discipline or related field of study with 2-5 years of experience in the biotech/pharmaceutical industry.
  • Experience performing and interpreting high quality quantitative in vitro ADME assays
  • Working knowledge of bioanalysis of nucleic acids (e.g. ASO, siRNA) using HPLC, mass spectrometry, ELISA, PCR
  • Have experience with biological sample handling including biological tissues.
  • Strong interest in the drug discovery process.
  • Be highly organized and able to work on multiple projects and meet established timelines.
  • Demonstrate the ability to work in a methodical and organized fashion; understand the material and documents workflow.
  • Knowledge of standard office software suite (data spreadsheets (Excel), MSWord, Powerpoint etc.) to generate internal reports and other documents.
  • Eagerness to acquire skills in LIMS and data management systems, specifically as it applies to sample inventory, tracking and chain of custody.
  • Established and demonstrated ability of clear and concise written communication.

What We’ll Offer You:

  • Comprehensive, competitive healthcare and dental coverage through Blue Cross Blue Shield, vision coverage through VSP, family leave, paid time off, 401k retirement plan, disability and life insurance, and fully covered parking/commuter benefits.
  • A dynamic early-stage work environment and highly interdisciplinary, talented, and collaborative team.
  • Participation in an unprecedented opportunity to advance a single tRNA medicine to restore disrupted protein production, regardless of target, for thousands of diseases with the same underlying genetic mutation.
  • Professional growth opportunities through mentoring, training, immersion in cross-functional projects, and opportunities to learn and try new things.
  • Daily on-site snacks, cold brew coffee, and Bevi, as well as weekly catered lunches.
