Job Description

Join Us as an Senior Scientist within our Biopharma team– Make an Impact at the Forefront of Innovation
We have successfully supported the top 50 pharmaceutical companies and more than 750 biotechs, spanning 2,700 clinical trials across 100+ countries in the last 5 years.

The Senior Scientist independently performs complex laboratory testing and provides hands-on technical coaching and mentorship within the laboratory. This role is focused on being an in-lab proven contributor who actively executes, troubleshoots, and improves testing activities while developing in-depth subject matter expertise in assigned methods, assays, or analytical platforms. A Senior Scientist may operate either as a non-routine technical contributor for method development, transfer, or validation activities or as a key technical resource for complex or priority routine testing. In all cases, the Senior Scientist remains directly involved in laboratory execution and testing oversight, owns non-routine technical deliverables within defined scope, and mentors Scientist I and II staff to ensure high-quality, consistent laboratory performance.

This role serves as a senior technical contributor and escalation resource within the laboratory. The Senior Scientist is responsible for the quality and technical accuracy of assigned deliverables (data, reports, methods, and protocols) but does not own overall program delivery, routine study management, or primary technical client communication. Client interaction may occur for method-specific technical discussions but does not include ownership of broader client relationships or project coordination. Scientific decisions that impact method lifecycle, validation strategy, or broader testing models are escalated to Staff Scientist + for approval. This role is distinct from a Study Lead and does not own routine study/program management, project coordination, or primary client-facing responsibilities.

What You'll Do:
•Independently performs complex laboratory testing, including challenging routine testing, analytical investigation support, development, transfer, or validation activities.
•Communicates analytical needs, resources, and/or barriers with relevant stakeholders.
•Maintains a strong hands-on laboratory presence and serves as a technical resource during test execution.
•Actively assists with testing execution, troubleshooting, and optimization rather than directing work from outside the lab.
•Applies advanced scientific judgment to execution strategy, data interpretation, and problem resolution.
•Develops and maintains subject matter expertise in one or more analytical methods, assays, or platform technologies.
•Serves as a technical escalation point for execution-level testing issues encountered during routine (release, stability, quality control) or non-routine (development, transfer, validation) work.
•Identifies method, execution, or workflow improvements that enhance data quality and downstream routine testing robustness.
•May independently execute or technically lead defined components of method development, transfer, or validation work.
•Authors and/or reviews non-routine technical deliverables such as methods, protocols, reports, and quality records.
•Supports transition of improved or newly established methods into routine testing by strengthening clarity, robustness, and usability.
•Acts as a key in-lab technical resource for complex or escalated routine testing.
•Assists analysts with execution strategy, atypical results, and troubleshooting for established methods.
•Supports quality management through hands-on data review and root cause analysis.
•Trains, mentors, and equips Scientist I and II staff through direct laboratory involvement and technical coaching.
•Reinforces best practices through example and active participation in testing activities.
