The best thing about my job
Everyday is different and never get bored with work tasks. Some days I work in laboratory and other times I am desk based to write documents.

It is worthwhile to select a Science subject for Leaving Cert. Many employees have a Science degree which would be the minimum qualification requirement for job application. There are general Science degree courses offered by many I.T. s and Universities which allow one to specialize in the following areas; Physiology, Zoology, Ecology, Biochemistry Genetics, Chemistry or Physics etc.

Skills Required

- Hard work, patience and perseverance
- A ‘can do’ attitude and determination to find solutions!
- Willingness to listen to others
- Desire to continue learning and developing your skills

My Main Tasks

  • Design and run bioassay experiments e.g. take up 3-4 hours with different incubations times
  • Lead team of analysts to transfer methods from one site to another
  • Prepare and review documents e.g. stability protocols, validation, shelf life extension and  transfer documents
  • Troubleshoot and investigate analytical method if there is an issue/problem with results
  • Use statistical software to analyse and trend product data to ensure the product is stable and behaving as expected
  • Go to meetings with team and discuss items that require resources, escalation items and identify areas for improvement.
  • Attend training and conferences to maintain skills and upskill in new areas.


Fast Paced environment and need to learn to think on your feet. It also requires a problem-solving mind as we encounter problems all the time and need to adapt and find the solution as they arise.

Who Influenced Me

I was always interested in Science and wanted a job that was challenging but also provided flexibility in working hours

Work/Life Balance

I have permanent job, with pension and health benefits along with opportunities for progression. I am empowered to participate in voluntary exercises such as this which allows me to give back to the surrounding community. Sometimes, critical work deadlines require overtime but this is a rare occurrence. Most times, I can work flexible hours to be able to attend classes or appointments etc.

Most Useful Aspects of my Education

Msc in Biotechnology as it included a 6-month work placement in a biopharmaceutical.

Useful Work Experience

3rd year college placement as part of the Degree course in a biopharmaceutical which provides 3-6months work experience including a project/thesis for college. This will provide practical experience in the industry and develop contacts that will help with future employment opportunities

Top Tip!

Pick a college course that offers a work experience or industry placement where possible. Practical experience is worth a lot!
