About the role

The Senior Scientist is an experienced scientific individual contributor responsible for investigating platform and assay performance issues, identifying root causes, and developing technical solutions to improve platform reliability and operational performance. As a member of the Operations Investigation Team (OIT), this role independently conducts scientific investigations, collaborates across functions, and drives continuous improvement through data-driven problem solving and process optimization.

Responsibilities:

  • Independently design, plan, and execute experiments to investigate platform performance issues and support troubleshooting efforts.
  • Analyze experimental data, identify root causes, and develop scientifically sound recommendations.
  • Develop, optimize, and troubleshoot experimental methods, workflows, and analytical tools to improve platform robustness, reliability, and efficiency.
  • Investigate sources of technical variability and recommend corrective and preventive actions.
  • Prepare technical reports, presentations, and investigation summaries to communicate findings and recommendations.
  • Collaborate with cross-functional teams, including R&D, Operations, Engineering, Quality, Manufacturing, and Data Science, to resolve platform-related issues.
  • Provide technical expertise in experimental design, troubleshooting strategies, and data interpretation.
  • Contribute to the development of new technologies, analytical tools, and process improvements that enhance platform performance.
  • Ensure compliance with laboratory safety, quality, and applicable regulatory standards.
  • These responsibilities summarize the role’s primary responsibilities and are not an exhaustive list. They may change at the company’s discretion.

  • Strong expertise in molecular biology, NGS technologies, assay development, or related experimental disciplines.
  • Experience with laboratory or biotech automation platforms (e.g., liquid handlers, robotic workcells, automated sample-processing systems) is highly desirable.
  • Proven experience independently designing and executing experiments and solving complex technical problems.
  • Demonstrated experience conducting root-cause investigations and developing practical technical solutions.
  • Strong scientific communication and technical presentation skills.
  • Experience working in regulated laboratory environments is preferred.

Preferred Qualifications:

  • Advanced troubleshooting, analytical, and root-cause investigation skills.
  • Strong experimental design and data interpretation capabilities.
  • Ability to manage multiple investigations and priorities in a fast-paced environment.
  • Strong collaboration and communication skills with cross-functional teams.
  • Innovative, self-motivated, and results-oriented with a continuous improvement mindset.

Physical Demands and Environment:

  • Work may be performed in laboratory and office environments with exposure to biological samples, chemicals, and laboratory equipment.
  • Requires appropriate personal protective equipment (PPE).
  • May require extended hours to support critical investigations.
  • Regular laboratory activities, including pipetting and operation of laboratory instrumentation.
