Biosensor Development Engineer - Limerick, Ireland
Originally posted 1 July 2026 by the employer — open 71 days.
About the role
This role involves contributing to the development of advanced biosensing technologies for medical and diagnostic applications. The scope includes the design, characterisation, and development of biomarker and dissolved gas sensors, with a particular focus on electrochemical sensing technologies.
What you'll do
- Contribute to the design and development of biomarker and/or dissolved gas sensor technologies.
- Plan and execute laboratory experiments for sensor characterisation and performance evaluation.
- Analyse and interpret data to inform design decisions and optimisation strategies.
- Drive improvements in sensor performance, including sensitivity, selectivity, stability, and reproducibility.
- Work with cross-functional teams (Quality, Test, Reliability, Manufacturing) to support development activities.
- Participate in testing involving biological or aqueous samples where required.
What you'll need
- BSc or MSc in Electrochemistry, Chemistry, Biochemistry, Materials Science, Chemical Engineering, Physics, or related discipline.
- 2–5 years’ experience in sensor development, electrochemistry, or related laboratory R&D work.
- Practical experience in experimental design, laboratory testing, and data analysis.
- Good understanding of electrochemical sensor principles and performance characteristics.
- Ability to work independently on defined tasks while collaborating within a multidisciplinary team.
- Strong problem-solving and analytical skills.
Nice to have
- Experience with biomarker sensing or dissolved gas sensor development.
- Familiarity with electrochemical techniques (e.g., potentiometry, amperometry, impedance spectroscopy).
- Experience working with biological samples.
- Exposure to product development environments, ideally within medical devices or diagnostics.
- Awareness of ISO 13485 or regulated development processes.
- Experience with materials relevant to sensors (e.g., membranes, enzymes, polymers).
