Intrepid Geophysics is looking for an experienced and technically strong potential field Geophysicist with significant Gravity expertise to join our team.

For more than 35 years, Intrepid Geophysics has developed specialist geophysical software used for potential-field data processing, interpretation and modelling around the world.

We are looking for someone who already has strong practical experience working with gravity data and can take responsibility for processing projects with limited supervision.

This is not an entry-level or graduate training position. However, we are not necessarily looking for someone with decades of experience. We are more interested in finding a technically capable geophysicist with strong fundamentals, good mathematical thinking and enough hands-on processing experience to independently investigate and solve difficult data problems.

The role A key part of this position will be working extensively with our INTREPID 3D geophysical processing software .

You will use INTREPID 3D for gravity data processing, quality control, interpretation and advanced problem solving. You will also work closely with our technical and software development teams, providing practical geophysical input into the ongoing development and improvement of the software.

A major part of the role will involve taking real-world geophysical datasets from initial inspection through processing and QA/QC to high-quality, defensible final products.

You will be expected to understand why a processing step is required rather than simply following an established workflow.

Responsibilities will include:

- Processing and QA/QC of ground, airborne and marine gravity datasets
- Using INTREPID 3D as the primary platform for gravity and potential-field processing
- Gravity data reduction and calculation of gravity anomalies
- Application and assessment of appropriate corrections, including drift, tidal, latitude, elevation/free-air, Bouguer and terrain corrections
- Levelling and network adjustment of gravity datasets
- Identifying and resolving survey, positioning, elevation, datum and processing problems
- Gridding, filtering and merging geophysical datasets
- Assessing data quality and distinguishing genuine geological signal from acquisition or processing artefacts
- Troubleshooting unusual or complex datasets where standard processing workflows are insufficient
- Working with gravity, magnetic and other potential-field datasets for geological interpretation




- Supporting 2D/3D gravity and potential-field modelling where required
- Documenting processing methodology, assumptions, parameters and QA/QC results
- Reviewing and improving existing processing workflows
- Testing INTREPID 3D processing tools and algorithms using real-world datasets
- Identifying software, workflow or algorithmic issues and working with the development team to investigate solutions
- Providing technical feedback that contributes to future improvements in INTREPID 3D
- Providing technical advice to clients and other members of the Intrepid team
- Supporting specialist technical training and customer projects when required

What we're looking for

- Degree in Geophysics, Physics, Applied Mathematics, Earth Sciences or a closely related discipline
- Strong practical experience with potential field / gravity data
- A solid understanding of the physics and mathematics behind gravity and potential-field methods
- Ability to independently take a gravity dataset from raw or field data through processing, QA/QC and final deliverables
- Strong understanding of gravity reductions, corrections, levelling, filtering and gridding
- Ability to diagnose problems in datasets rather than relying only on predetermined processing workflows
- Strong numerical and analytical problem-solving skills
- Good understanding of coordinate systems, elevations, datums and positioning as they relate to gravity processing
- Ability to assess whether a processing result is geophysically and geologically reasonable
- Ability to clearly document and explain technical decisions
- Confidence learning and working deeply with specialist geophysical processing software

We expect applicants to already have meaningful commercial, government, research or survey-processing experience. Typically, this would come from approximately 5+ years of relevant work, but demonstrated technical capability is more important to us than a particular number of years. Previous INTREPID 3D experience is valuable but not essential .



We are looking for someone with sufficiently strong gravity-processing fundamentals that they can become productive in the software quickly without requiring extensive training in geophysical concepts.

Highly desirable

Experience in one or more of the following would be particularly valuable:

- Airborne gravity or gravity gradiometry
- Marine gravity processing
- Ground gravity survey processing
- Full Tensor Gravity / FTG or FALCON data
- Magnetic data processing and interpretation
- Potential-field modelling and interpretation
- Terrain corrections and high-resolution DEM processing
- Survey levelling and network adjustment
- Combining gravity information with seismic, geology or other geophysical datasets
- Python, MATLAB or similar numerical/scientific programming
- Development, testing or validation of geophysical algorithms
- INTREPID 3D or other professional potential-field processing software

The person we're looking for Technical knowledge is important, but equally key is how you approach a problem.

You are likely to enjoy this role if you are the person who receives a difficult dataset and wants to understand why it doesn't behave as expected .

You should be comfortable questioning the data, testing assumptions, working through the mathematics and trying alternative approaches until you understand the problem.

We are particularly interested in someone who is:

- mathematically strong and analytical
- curious about unusual data behaviour
- able to work independently
- systematic with QA/QC
- comfortable solving problems that don't have an obvious answer
- willing to investigate the underlying physics rather than treating processing software as a black box
- able to communicate complex technical issues clearly to both specialists and non-specialists
- interested in using their practical geophysics experience to help improve specialist geophysical software.

Why Intrepid? This position offers an opportunity to work much more deeply with geophysical processing than a typical production-processing role.

You will work directly with INTREPID 3D , complex international datasets and the people developing the algorithms and processing tools behind the software.

Your work will contribute both to solving real geophysical problems and to improving the technology used by geoscientists internationally.

If you are a hands-on geophysicist who enjoys mathematics, data and solving difficult gravity-processing problems, we would like to hear from you.
