Alltrna is an entrepreneurial and innovation-driven organization seeking to hire an exceptional Research Associate to join our growing team. As a Senior Research Associate/Associate Scientist, you will work to support key development programs and senior team members by conducting in-vitro studies to support our tRNA platform screening efforts. You will be generating and maintaining mammalian cell lines as well as conducting various assays (cell-based, molecular, biochemical, and immune) based on established protocols. As key member of our Lab Automation and Discovery Screening teams; you will play a critical role in our efforts to adapt traditional assay technologies into HTS amenable formats and executing production runs on HTS platforms composed of liquid handlers, plate readers, flow cytometers, high content imagers, and data capture software for biologics discovery. A successful candidate will have an educational degree in Biology, Chemistry, or a related field and will have direct experience working in a research laboratory setting. The candidate’s career goals, technical skills, and core competencies should be aligned with the description below 

Core Responsibilities  

  • Participate in high throughput cell-based assay development; and perform cellular/molecular biology techniques including the generation of stable reporter cells for fluorescence, qPCR, and luciferase related assays.  
  • Follow and execute standardized protocols for high to medium throughput assays, with high attention to detail and effectively communicating results 
  • Utilize lab automation equipment and high-throughput instrumentation to conduct assays and experiments 
  • Assist colleagues in experiments to optimize precision, accuracy, reproducibility, and throughput for core platform assays  
  • Execute and optimize processes within the lab to increase efficiency and effectiveness, including managing biologics inventory, lab consumables, chemicals, and equipment. 
  • Work closely with engineering/scientific colleagues to perform HTS/HCS campaigns, and to streamline data analysis workflow. Analyze experimental data and present results at project/team meetings. 
  • Convert traditional low-throughput biochemical and cell-based assays into HTS amenable formats. (Experimental Design, Assay Optimization, Method Validation, and Root Cause Analysis).
