Work‑life balance and flexibility is a key focus area for us. We’re happy to discuss hybrid, part‑time and flexible working hours, patterns and locations to suit you and our business.
We are looking for a motivated Junior Geophysicist with at least two years of professional experience to join our Subsurface Solutions team within the Earth and Environmental Operations Area. You will bridge the gap between complex data collection and practical engineering solutions, supporting environmental, defence and energy projects.
This is a hybrid role involving hands‑on field data acquisition, advanced processing, and technical reporting.
You will be working within a multidisciplinary team with specialities in low strength sedimentary rock, high strength rock and Quaternary geology, and in disciplines ranging from hydrogeology, land quality, geotechnical engineering, engineering geology and geoscience‑related safety case work. Much of the work we undertake involves siting, site characterisation, site descriptive models and understanding subsurface conditions and hazards. In addition, you will be encouraged to work with the wider Amentum community to further strengthen the team’s capabilities. You will also gain experience in complex bid preparation, project management and technical planning. As a result, we are looking for people who have the passion and drive to be involved with major projects with strong adaptability, prioritisation and team‑working skills.
Whilst much of our work is focused on exciting projects that form part of Amentum’s Energy, Environment and Defence businesses. We would be interested in candidates with experience in carbon capture and storage (CCS) and geothermal energy, which could complement future growth opportunities.
Our values are built on a strong foundation of safety, integrity, and respect for every individual. People are at the heart of our mission, and we believe in supporting one another through a culture of care and collaboration.
We strive to create a workplace where everyone feels they belong and can thrive. Supporting mental wellbeing and fostering a sense of connection are essential to how we work.
When we embrace different perspectives and work together, we become more innovative, more agile, and more successful.
