🎯 Role Definition

The Associate Scientist is an early-career R&D professional responsible for designing, executing and documenting experiments that support product development, quality testing and regulatory submissions. Working within cross-functional teams, the Associate Scientist performs hands-on laboratory work (cell culture, molecular biology, analytical assays), maintains laboratory compliance with SOPs and GLP/GMP standards, analyzes data using statistical and bioinformatic tools, and communicates findings through technical reports and presentations. Ideal candidates balance strong technical capabilities with disciplined documentation, safety awareness and collaborative communication.

  • Analyze experimental data using statistical software and scripting languages (GraphPad Prism, R, Python), produce clear figures and perform statistical tests to support conclusions and decision-making.
  • Prepare and maintain complete, contemporaneous laboratory notebooks, electronic lab notebook (ELN) entries and LIMS records with traceable metadata, sample IDs and audit-ready documentation.
  • Execute sample preparation, extraction and purification workflows for small molecules, proteins and nucleic acids in support of downstream analytical assays.
  • Support method transfer and tech transfer activities by documenting procedures, training receiving personnel and running comparative studies to ensure reproducibility across sites or partners.
  • Contribute to stability programs by planning and executing accelerated and long-term stability studies, analyzing stability-indicating parameters and reporting trends to project teams.
  • Troubleshoot assay performance and instrument issues proactively, implement corrective actions, and escalate complex technical problems to senior scientists or instrument vendors when necessary.
  • Participate in cross-functional project teams (R&D, QC, regulatory, manufacturing) to align experimental plans to program timelines and regulatory requirements.
  • Prepare technical reports, experimental summaries, SOP drafts and sections of regulatory documentation (e.g., CMC summaries, assay validation reports) to support submissions and internal reviews.
  • Maintain laboratory stock, reagents and consumable inventories, manage ordering and vendor relationships to minimize inventory shortages and ensure consistent experiment throughput.
  • Follow and enforce lab safety policies, hazardous waste disposal procedures and biohazard containment guidelines; participate in safety training and maintain certifications where required.
  • Execute quality control testing for raw materials, in-process samples and final products, including documentation of acceptance criteria, deviations and release decisions in partnership with Quality teams.
  • Assist in the development and implementation of new protocols and process improvements to increase throughput, reduce cost or improve assay robustness and reproducibility.
  • Mentor and train junior technicians and interns on day-to-day laboratory practices, instrument operation and documentation standards to build bench competency across the team.
  • Support sample logistics, chain-of-custody and biobanking operations, ensuring proper labeling, storage conditions and accurate sample traceability.
  • Conduct literature searches and stay current with technical advances, assay technologies and analytical methods relevant to assigned projects and recommend new approaches when appropriate.
  • Collaborate with external vendors and CROs to design studies, coordinate sample shipments, and review vendor-generated data for completeness and scientific soundness.
  • Participate in periodic audits and inspections by internal QA or external regulatory bodies, prepare requested documentation and implement corrective actions to address any findings.

Secondary Functions

  • Support ad-hoc data requests, exploratory data analysis and visualization to answer tactical project questions and support decision-making by project leads.
  • Contribute to the organization's scientific strategy by identifying technical risks, proposing mitigation experiments and aligning lab activities to program milestones.
  • Assist with budgeting and resource planning for experiments, identifying high-cost items and proposing cost-effective alternatives without compromising data quality.
  • Participate in method development workshops, technology scouting exercises and pilot studies to evaluate new instruments, reagents or automation platforms.
