We are seeking an experienced Senior Biologist On-Call to provide expert biological support across a range of operational, technical and field-based activities. This role will suit a highly capable professional who can respond effectively to changing priorities, assess biological risks and provide sound, evidence-based advice in time-sensitive situations. You will work closely with multidisciplinary teams, stakeholders and specialist contractors to support the safe, compliant and efficient delivery of environmental and biological programmes.

You will need excellent organisational and problem-solving skills, attention to detail, and a flexible approach to working hours and locations. A full driving licence, willingness to travel and the ability to work safely in challenging field conditions may also be required.
