Research / Senior Research Associate - Protein Expression (12 month fixed term maternity cover)

At F-star, we are dedicated to developing next generation immunotherapies to transform the lives of patients with cancer. We develop mAb², a novel class of disruptive bispecific antibody-based therapies that have the potential to overcome tumour resistance and restore anti-cancer immunity and responsiveness.
We are committed to delivering life-changing treatments for the estimated 80% of patients with cancer who currently fail to have a durable response to immunotherapies.
Our wholly owned pipeline shows focused and potent immune activation, with a promising safety profile to date.
We’re an agile, international team with dual headquarters in Cambridge, UK and Cambridge, Massachusetts. We empower our teams to decide where and when they work to deliver our goals.
We are looking for a Research Associate to join our Protein Sciences Team. Working within the Protein Sciences group, you will proactively contribute to the development and delivery of analytical capabilities to support our technology platform and mAb2 bispecific pipeline. Analytical capabilities are required to deliver protein engineering, research grade production and process development activities with a key focus on protein characterisation and developability assessments.
• Delivery of analytical methods for characterisation of F-star mAb2 pipeline with a key focus on SE HPLC, HIC HPLC, Ion exchange/ charge heterogeneity and analytical method development
• Formulation, characterisation and stability studies of mAb2 molecules
• Critical interpretation of data to draw results driven conclusions and define project progression

We’re looking for someone who is adaptable, keen to learn and confident in delivering work with limited supervision. You’ll be organised with strong attention to detail with an ability to keep clear records. You will be able to maintain rigid controls and analysis during multiple experiments. Strong communication skills are important along with the proven ability to work well within teams, both in person and in a virtual environment. This is a busy role with deadlines to meet and so you’ll be able to prioritise your workload and adapt quickly to change when needed.
• Bsc/MSc in relevant subject with relevant experience ideally in industry.
• Demonstrated experience in applying Chromatography techniques including UHPLC (SEC, RP, IEX)
• Demonstrate good knowledge of protein biophysical properties and stability
• Demonstrated scientific credibility and ability to drive decisions through scientific expertise; proven ability to interpret complex data
• Team player and ability to work in teams with different skills
• Solution-finding, and agility as evidenced by flexibility, adaptability to change, curiosity, and ability to lead and drive change
• Excellent verbal and written communication skills

• Experience and breadth of knowledge in analytical and biophysical characterisation of recombinant biotherapeutics for CMC development. (e.g. formulation, protein aggregation, protein stability and post-translational modifications including glycosylation).
• Demonstrated experience in analytical and biophysical characterisation of recombinant biotherapeutics.
• Knowledge of recombinant proteins
• Knowledge and experiences in biophysical methods for characterisation of protein conformation (Light Scattering, DSC, DSF, CD,)

We get things done, we keep things simple, and we’re driven by the science. We’re ambitious so we work hard to create an environment where we can take smart risks. We want to be innovative so encourage debate and collaboration to challenge the usual way of doing things. We love our celebrations, socialising and perks, which make F-star a fun and diverse place to work. And most of all, everyone has the opportunity to make a difference.
