Senior Research Associate - Protein Biotherapeutics (6 months Fixed-Term)

We are a fast-growing biotech start-up focusing on next-generation precision biologics, driven by science, collaboration, and curiosity. We are looking for a hands-on Senior Research Associate, in Protein Biotherapeutics, to join our discovery team and advance the development of next-generation therapies.

This is a lab-based role suited for someone who enjoys variety, ownership, and being deeply involved in day-to-day experimental work while actively contributing to scientific discussions.

What you will do

As a Senior Research Associate, you will be an integral part of our discovery and biotherapeutics efforts, with responsibilities spanning molecular biology, protein engineering, and protein characterisation (training will be provided where necessary):

• Design, express, purify, and characterise recombinant proteins and antibody-based molecules


• Perform and optimise protein purification workflows using chromatography techniques including affinity, ion exchange, and SEC


• Conduct biophysical and biochemical characterisation of proteins using techniques such as SPR, ELISA, SDS-PAGE, HPLC, DLS, and thermal stability assays


• Design and execute SPR experiments to evaluate binding kinetics, affinity, and epitope interactions


• Support protein engineering campaigns including mutagenesis, construct design, sequence analysis, and optimisation of protein properties


• Contribute to computational or structure-guided protein design activities where appropriate


• Maintain laboratory instruments and ensure smooth day-to-day lab operations


• Accurately document experiments, analyse data, and contribute to internal reports


• Establish and improve protocols


• Actively participate in scientific discussions, data reviews, and project meetings


• Collaborate closely with colleagues across the company

What we are looking for

• BSc, MSc, or equivalent experience (≥3 yrs) in Biochemistry, Biotechnology, Molecular Biology, or a related field


• Hands-on experience with SPR platforms (e.g. Biacore)

• Strong background in protein purification and analytical characterisation


• Knowledge of protein engineering principles and molecular biology techniques


• Experience with recombinant protein expression in mammalian systems


• Familiarity with protein design tools, structural biology, or in silico analysis is advantageous


• Highly organised, detail-oriented, and comfortable in performing multiple tasks


• A proactive and flexible mindset


• Strong communication skills and enjoyment of working in a collaborative and social team environment
