To make it happen, we work as One Team and ask ourselves, “How can we?” (Even when others say, “We can’t.”)

We’re proud of our history as pioneers, problem-solvers, and pragmatists. And as we strive to achieve our Vision2040, we’ve got our sights set on a culture that is focused and disciplined to drive value, and entrepreneurial and energised to leave a positive legacy.

• Comprehensive knowledge of Subsurface GG&E practices, procedures and industry standards
• Continuous improvement, mentoring colleagues and elevating data literacy
• PPDM Professional Data Management certification is highly desirable.

What you’ll get:

Here, you’ll be amongst high-calibre people and get to work on industry-leading projects. We don’t shy away from solving tough problems at pace. We like it that way. You can expect to be challenged and supported; to learn and grow.

At Santos, we’re committed to creating a workplace where everyone can thrive. This means a place that is safe; where you are valued and respected, and your contribution is recognised and appreciated. Join us, and you’ll play a role in this too.
