Process Engineer — Upstream (Vaccine Manufacturing Project)
We have an opening to support our client, a leading global vaccine manufacturer, on a capacity expansion project at their Singapore manufacturing site.
About the project
New materials, equipment and process trains are being introduced alongside a facility that continues to produce commercially, so the work has to progress without disrupting ongoing GMP operations.
Commissioning of upstream equipment
- Site commissioning of new upstream equipment including bioreactors, media and buffer preparation vessels, skids and transfer systems
- SAT support, loop checks, system walkdowns, and punch list generation and closure
- Executing IQ and OQ protocols, redlining, and resolving protocol deviations through to closure
- CIP and SIP cycle commissioning and troubleshooting, and supporting clean utility tie-ins
- Working alongside vendors, engineering, automation and QA from commissioning through to handover into operations
Material qualification
- Qualifying new and alternate raw materials, media components, single-use consumables and filters for use in the upstream process
- Running comparability and equivalence studies against incumbent materials, and defining acceptance criteria
- Assessing extractables and leachables, compatibility and supplier change notifications, and coordinating with suppliers on technical documentation
- Managing material introduction through change control, from justification and risk assessment to implementation and closure
Upstream process support
- Providing day-to-day technical support to upstream operations across seed train, cell culture and harvest
- Monitoring process performance and critical process parameters, trending batch data and flagging drift before it becomes a deviation
- Supporting media and buffer preparation, bioreactor operation, and the interfaces into downstream
- Reviewing and revising batch records, SOPs and process descriptions as the process is established
Trial runs and PPQ
- Planning and executing engineering runs and trial batches, defining objectives, sampling plans and acceptance criteria
- Authoring and executing Process Performance Qualification protocols, and writing the summary reports that support GMP release
- On-floor support through runs, capturing observations in real time and feeding them back into the process definition
- Supporting continued process verification in routine production
Troubleshooting and change control
- Investigating process deviations and out-of-specification results, applying structured root cause analysis and driving CAPA to closure
- Diagnosing process and equipment issues on the floor alongside operations, automation and engineering
- Raising, assessing and closing change controls for process, material and equipment changes, including impact assessment on validated status
- Supporting inspection readiness and providing technical justification to QA
What we are looking for
- Degree in chemical, bioprocess or biochemical engineering, biotechnology or a related discipline
- 3 to 5 years in GMP biologics or vaccine manufacturing, with a strong grounding in upstream unit operations
- Commissioning and qualification experience, specifically IQ and OQ protocol execution on process equipment
- Hands-on experience of process validation, including PPQ protocol authoring and execution
- Demonstrated deviation investigation and root cause analysis capability, with CAPA ownership
- Working knowledge of change control and its impact on validated status
- Comfortable on the shop floor during runs, and able to work where the process is still being established
- Accurate technical writing and good spoken English
