Senior Researcher - Recombinant Proteins


Are you a molecular biologist or biochemist with vast experience in recombinant proteins?

Do you feel that you have outgrown your current position, or that your career has come to a standstill?

Are you passionate about your work and would like to see it applied on a global level with genuine benefits for humanity?

Would you like to work for a Spanish consolidated company that is keen to attract and nurture top scientific talent?


Why do you ask?



Who’s Immunostep?

This rapidly growing biotechnology company began its life over twenty years as a spin-off of Salamanca University.

They hold distribution and licensing deals in over twenty countries around the world and boast a wide range of diagnosis and clinical research products.

Besides, they have led national and international research projects and received numerous awards for our work.

Their goal is to become a global leader in early diagnosis of cancer, infectious and immune system diseases.


Is this job for me?... Yes, if…

·       You are specialist in cloning and mammalian recombinant protein expression and purification.

·       You hold demonstrable knowledge and experience of relevant functions or, ideally, a doctorate.


Ok, so what can you offer me?

·       An ongoing contract from the R&D Department, reporting directly to senior management

·       Potential for career development, with excellent promotion prospects for a future with the company.

·       Freedom to continue writing scientific articles while your research is applied to products available on the market.

·       A pleasant, collaborative, innovative and stimulating work environment.

·       A flexible starting time tailored to employees’ individual preferences, and a working day of 8 hours.


Who will I be working with?

Our dynamic, young multi-disciplinary team includes biologists, biochemists, engineers, IT specialists and economists, among others.


Where will I be working?

Known for its ornate sandstone architecture and the historical University of Salamanca, this ancient city is one of Spain’s most beautiful. Salamanca is a pleasant place to live, with good connections to Madrid, other cities in the region and Portugal.


What duties will I have?

You will be responsible for:

·       Fine-tuning and optimising production protocols, purifying and characterising recombinant proteins in expression systems such as mammals, yeasts and insects.

·       Generating expression vectors for recombinant protein production.

·       Transforming cells with these vectors, cell culture for expression and purification of recombinant proteins.

·       Conducting essential molecular biology techniques to evaluate the validity of the genome constructions and their effect on the cell line and characterisation of recombinant proteins.


Is there anything else I need to know?

·       The offer is open exclusively to researchers with EU work permits.

·       You should be a very self-reliant person who can bring something to the company, as you will be our main expert in your field.

·       You will lead projects, so you will need to be very autonomous and proactive.

·       A successful track record in obtaining public funding for previous research projects is also desirable.
