What a QA Officer actually does at a Dutch CDMO

Job descriptions for QA Officers are interchangeable. "Ensure compliance with GMP." "Review batch documentation." "Support continuous improvement." None of that tells you what Tuesday looks like. Here is Tuesday.

07:45, The release queue

At a CDMO the day starts with the batch disposition queue. Three executed batch records came off the night shift: a lyophilised product for a US client, two vials batches for an EU client. The 14:00 release meeting needs a QA recommendation on each. You are looking for what matters, a missed second-person verification on a critical step, an in-process result outside the alert limit that nobody commented on, a line clearance signed before the previous batch was reconciled. You are not looking for the missing date on page 41. A good QA Officer knows the difference and does not treat them the same.

09:30, The deviation that arrived overnight

The lyophiliser logged a shelf temperature excursion at 03:12 for eleven minutes. Production's initial write-up says "no impact, product within cycle parameters". Your job is to decide whether that is true. You pull the cycle data, check the product's validated cycle limits, look at whether the excursion was during primary or secondary drying, and classify it. Then you push back on the root cause, "sensor drift" is a symptom, not a cause, and agree a CAPA that production will actually do.

11:00, Change control

A supplier wants to change the sterilising-grade filter membrane. Engineering says it is equivalent. You ask the questions Annex 15 asks: does this touch the validated state? Is a filter validation study with the actual product required? Does the client's technical agreement require notification? At a CDMO the answer to the last one is almost always yes, and someone has to write that email.

13:00, Client audit prep

Thursday, a client auditor arrives for two days. The QA team splits the standard requests: training records for the filling line operators, the last twelve months of EM trending, open CAPAs over 90 days. You pull your part and make sure the answers are the same as what the client saw last year.

14:00, Release meeting

QA, production, QC and the QP for 40 minutes. Your recommendation on each batch is one line and one reason. The QP will ask about the lyophiliser excursion. You have the data.

What separates the people who thrive

Three things, in our experience of placing several hundred QA Officers.

• Judgement under time pressure. The queue does not stop. You have to decide what is critical in the time available.
• Comfort with friction. Production will not love you. Neither will the project manager whose change control you sent back. The best QA Officers hold a line without making it personal.
• Curiosity about the process. QA Officers who understand how a lyophiliser works write better deviation assessments than those who only know the SOP.

Pay and next steps

Medior QA Officers at Dutch CDMOs earn €52–62k, seniors €62–75k, with Leiden at the top of that range. The most common next roles are QA Specialist (system ownership), QA Team Lead and, for those who meet the education criteria, Deputy QP. See the QA salary guide and our current QA vacancies.
