Your next challenge
Ready to make a difference? Here's what awaits you.
As an HPLC / LC-MS Laboratory Engineer, you will join a team of five scientists and report directly to the Technical Leader. Working with a remarkable diversity of samples, including small molecules, proteins, oligonucleotides, viral vectors, mRNA vaccines, peptides, formulation excipients and nanoparticles, you will play a direct role in generating the analytical evidence that supports the development of future medicines.
From early research activities through to clinical development and commercialisation, your expertise in liquid chromatography coupled with mass spectrometry will help ensure the quality, reliability and regulatory compliance of pharmaceutical products. Every analysis you perform contributes to bringing safe and effective therapies to patients faster.
Your key responsibilities
Here's what you'll be in charge of:
- Applying existing analytical methods to determine the identity, purity, and assay of various products in compliance with GMP requirements
- Applying existing analytical in the context of bioanalytical studies in compliance with GLP (Good Laboratory Practice) and GcLP (Good Clinical Laboratory Practice) requirements
- Developing, validating, and adapting analytical protocols to meet specific project needs
- Performing analyses using state-of-the-art LC-MS instrumentation, including XevoTQ systems, QDa, and LC-SQD2
- Conducting stability studies and QC release testing
- Processing and interpreting analytical data
- Preparing analytical reports and related scientific documentation
Skills you'll need to bring
To succeed in this role, you'll demonstrate:
- A scientific Bachelor's degree (BAC+3) or Master's degree (BAC+5)
- Initial professional experience in liquid chromatography and/or liquid chromatography coupled with mass spectrometry (LC-MS)
- Knowledge of analytical method application, validation, and development principles
- The ability to interpret analytical data and draw scientific conclusions
- Knowledge of GMP and/or GLP environments is considered an asset
- Experience with Empower and/or MassLynx software is an asset
