Our culture encourages personal expression, open dialogue, and genuine connections, where you are valued, accepted and respected for who you are, allowing you to thrive both personally and professionally. This is how we aim to prevent, stop and cure diseases and ensure everyone has access to healthcare today and for generations to come.

Join Roche, where every voice matters.

The Analytical Research & Development department (PTDC-A) is part of Pharma Technical Development (PTD) and responsible for analyzing drug substances and dosage forms of synthetic molecule development products. The ultimate goal of our work is a robust control strategy to release pharmaceutical products for clinical trials, and finally for commercial supply.

The “Hyphenated & Special Technologies (HST)” section provides key scientific customer support mainly with Mass Spectrometry (MS), separation sciences and innovative special technologies. More than 20 mass spectrometry experts verify the safety and quality of our products by identity testing, characterization and quantification of any type of impurities.

As our new member of the HST team, you will step into a pivotal role, acting as an analytical detective. You will use state-of-the-art high-resolution LC-MS and GC-MS systems to solve complex structural puzzles, identifying and characterizing unknown impurities in our small molecule, oligonucleotide, and peptide portfolio. Your work will directly impact project decisions, accelerate development, and ultimately ensure the quality and safety of medicines for patients.

• Solve analytical challenges by independently designing and executing hands‑on lab experiments for the structure elucidation of unknown impurities from e.g. process development, forced degradation studies, and troubleshooting activities.

• Apply your expertise in cutting‑edge techniques including qualitative LC-HRMS, 2D-LC-HRMS, and GC-HRMS to analyze complex drug substances and drug products.

• Critically evaluate and interpret complex analytical data and provide clear and concise conclusions in English that guide project teams and support regulatory filings.

• Actively identify opportunities to enhance our workflows, evaluate new software tools, and contribute to the continuous improvement of our analytical capabilities.

• Proactively partner with project leads and stakeholders across various functions, ensuring analytical insights are directly communicated, understood, and integrated into project decisions.

• Actively participate in cross‑functional projects and proactively share knowledge and insights with colleagues, both within our group and across the wider organization.

You are a passionate analytical expert who finds deep satisfaction in solving complex structural puzzles and sharing your knowledge. You thrive in a collaborative, high‑tech environment and are motivated by the direct impact your work has on developing new medicines.

• A higher education (Master's or PhD in Chemistry, Biochemistry, or related field) or an apprenticeship as a laboratory technician with a minimum of 5 years of direct, hands‑on experience in structure elucidation using LC-HRMS.

• Proven, in‑depth experience in interpreting high‑resolution MS and MS/MS spectra for small molecules, peptides, or oligonucleotides.

• Hands‑on skills in developing and optimizing chromatographic (HPLC, GC) and mass spectrometry methods.

• Basic NMR experience

• A pragmatic, proactive, solution‑oriented, and accurate workstyle that effectively balances independent project responsibilities with active team collaboration.

• Excellent communication skills and fluency in English and proficiency in German

• A keen interest in digital innovation, with exposure to tools like Gene Data Expressionist®, ACD/Labs or programming languages (Python, JavaScript).

• Practical experience with the maintenance and troubleshooting of HPLC, GC and MS instrumentation, as well as hands‑on experience with 2D‑LC‑MS and preparative HPLC.

• Comfortable and experienced in working with MS…
