Strong team ethic We are a close-knit, dynamic team (and it’s not just the usual corporate cliché!). We value the trust we have in each other and our work. This is reciprocated by transparency, and diligence. We collectively strive to provide and preserve work-life-balance. Attention to detail Attention to detail is required in all aspects of the job, whether that be working safely in laboratory space, or writing up experimental procedures and recording data in lab books. Life in a small biotech is heavily goal and milestone driven, and it is crucial that we are focussed and in control of as many details as possible. Interpersonal skills The quality and cohesiveness of a team is often the number one determinant of success for a small company. It is therefore absolutely essential to demonstrate respect for, and consideration of, others and their work. This means needing to work conscientiously and professionally, and to have the ability to communicate effectively with others - particularly regarding the presentation of scientific data at an appropriate level. This includes, for example, the ability to create high quality presentations of data, the ability to produce informative figures, slides and documentation, but also to communicate within the team to achieve common goals. Agile Ability to work to deadlines, particularly when more than one project may demand time commitment.
