Job brief

We are seeking a detail-oriented Laboratory Technician to join our dedicated Quality Control team and advance our mission of delivering safe, life-saving therapeutics. In this role, you will be responsible for precise analytical testing, instrumentation maintenance, and the rigorous documentation required to support our clinical and commercial production pipelines. You will partner with experienced scientists to solve complex stability challenges, contributing directly to the safety and efficacy of our pharmaceutical portfolio. If you are passionate about precision science and eager to work in a high-impact, regulated environment, we invite you to apply.

Key highlights

Execute standardized analytical procedures using HPLC, UV-Vis, and titration methods to verify pharmaceutical product potency and purity.
Document all experimental data and testing results into LIMS or ELN platforms, ensuring 100% adherence to ALCOA+ data integrity standards.
Investigate and document out-of-specification (OOS) results, performing comprehensive root-cause analysis to support corrective and preventive action (CAPA) processes.
Support periodic audits and regulatory inspections by providing detailed, organized documentation regarding batch release and stability testing activities.

What is a Laboratory Technician?

A Laboratory Technician is a highly specialized scientific professional tasked with executing rigorous analytical testing and experimental protocols within a pharmaceutical or biotechnology environment. By operating advanced instrumentation like HPLC, GC-MS, and dissolution testers, a Laboratory Technician maintains the highest levels of data integrity and sample accuracy throughout the drug development lifecycle. Their work serves as the primary safeguard for product quality, ensuring every batch meets strict USP, EP, and internal manufacturing specifications before reaching the market.

What does a Laboratory Technician do?

On a daily basis, a Laboratory Technician prepares complex chemical reagents, performs raw material and finished product assays, and documents findings in an Electronic Laboratory Notebook (ELN) or LIMS. They execute stability testing protocols, troubleshoot analytical equipment malfunctions, and perform routine equipment calibration to remain in compliance with strict GLP/GMP requirements. Beyond the bench, they collaborate with Quality Control (QC) supervisors and research scientists to investigate out-of-specification (OOS) results, ensuring that all pharmaceutical operations maintain continuous, audit-ready compliance.

Key responsibilities

Execute standardized analytical procedures using HPLC, UV-Vis, and titration methods to verify pharmaceutical product potency and purity.
Document all experimental data and testing results into LIMS or ELN platforms, ensuring 100% adherence to ALCOA+ data integrity standards.
Perform daily calibration and preventative maintenance on analytical laboratory instrumentation to ensure continuous operational readiness for QC testing.
Investigate and document out-of-specification (OOS) results, performing comprehensive root-cause analysis to support corrective and preventive action (CAPA) processes.
Prepare laboratory buffers, mobile phases, and chemical reagents according to validated pharmacopeial (USP/EP) monograph specifications.
Monitor environmental conditions and maintain laboratory safety standards, ensuring full compliance with OSHA and internal biosafety level requirements.
Support periodic audits and regulatory inspections by providing detailed, organized documentation regarding batch release and stability testing activities.
Coordinate with supply chain and production departments to schedule priority sample testing, ensuring timely release of pharmaceutical batches for distribution.

Requirements and skills

Bachelor’s degree in Chemistry, Biochemistry, Pharmacy, or a closely related scientific field from an accredited institution.
1+ years of hands-on experience working in a regulated pharmaceutical or biotechnical laboratory environment (GLP/GMP).
Proficiency with advanced analytical instrumentation including HPLC, GC, LC-MS, and Karl Fischer moisture titration systems.
Deep understanding of current Good Manufacturing Practices (cGMP) and 21 CFR Part 11 requirements for electronic records.
Proven ability to perform technical writing and data interpretation for laboratory reports, validation summaries, and standard operating procedures (SOPs).
Experience using Laboratory Information Management Systems (LIMS) and chromatography data systems like Empower or Chromeleon.
Demonstrated problem-solving skills, specifically regarding the troubleshooting of complex chemical testing methodologies and instrumentation hardware.
Ability to communicate complex technical findings clearly to Quality Assurance teams and cross-functional pharmaceutical stakeholders.

FAQs

What does a Laboratory Technician do in a pharmaceutical company?

A Laboratory Technician is primarily responsible for performing analytical testing on raw materials, intermediates, and finished pharmaceutical products. They ensure that all chemical and biological assays are executed according to validated protocols and cGMP standards. Their daily work involves operating high-end analytical equipment, analyzing test data, and maintaining the rigorous documentation necessary for regulatory approval.

What skills are required to be a successful Laboratory Technician?

Success in this role requires technical proficiency in analytical chemistry techniques, such as chromatography and spectroscopy, alongside a strong grasp of GLP and GMP compliance. Essential skills include extreme attention to detail for documentation, the ability to operate and troubleshoot complex laboratory instrumentation, and strong technical writing capabilities. Furthermore, critical thinking skills are necessary to analyze testing anomalies and support root-cause investigations.

Who does a Laboratory Technician work with on a typical day?

A Laboratory Technician works in a highly collaborative environment, interacting daily with Quality Control (QC) analysts, Quality Assurance (QA) specialists, and research scientists. They also coordinate with manufacturing teams to prioritize product testing and provide data-backed insights to regulatory affairs teams during audit preparation. This collaborative effort ensures that all pharmaceutical products meet safety and efficacy benchmarks before release.

Why is the role of a Laboratory Technician so important?

The Laboratory Technician acts as the final gatekeeper for product quality, ensuring that medications delivered to patients are safe, stable, and effective. Without the precise testing and documentation provided by these technicians, companies could not verify compliance with FDA or EMA requirements. Their role is central to mitigating risks, preventing manufacturing failures, and upholding the integrity of the entire pharmaceutical supply chain.
