Scientist monitoring geophysics Utrecht

About this position

Have you just finalised your Master in geophysics/geomechanics/seismology and are you passionate to continue learning about geophysical surveying and monitoring technologies? Would you like to become more adept at signal processing, and subsurface imaging using the latest sensing technologies? Do you want to work on innovative research projects that contribute to the energy transition, safe subsurface operations, and scientific breakthroughs? Are you excited to work in an international applied research environment, and are genuinely curious, dedicated, and a have willingness to learn?

We are seeking a dynamic and motivated Geophysicist to contribute to geophysical monitoring and imaging projects to strengthen our team. This is your opportunity to work on cutting-edge projects that make a real impact on the future of sustainable energy.

What will be your role?

The general aim of your work is to improve our understanding of subsurface processes through advanced geophysical imaging and monitoring technologies, with a strong focus on fiber optic sensing and seismic imaging methods.

As a researcher you will be working with experts from the geophysics and geomechanics teams on a wide range of monitoring and imaging data sets acquired in TNO projects and industrial collaborations. You will contribute to the development of robust and future-proof workflows for storing, processing, imaging, monitoring and interpreting these data sets. The work focus is twofold and focusses on active seismic imaging and monitoring, as well as on induced seismicity monitoring. For your work you will have access to (deep borehole) geophone data, fiber optic data obtained in boreholes or from (dark-fiber) networks and nodal seismic data. Your activities will vary from project to project and may include DAS-VSP processing, seismic imaging, signal enhancement, the detection and localization of (induced) seismic events, focal mechanism analysis, time-lapse monitoring, and data integration. Depending on your interests and project needs, you may also contribute to machine learning applications, monitoring system design, geophysical field work and field deployments, and the development of innovative geophysical workflows.

The work will contribute to our research on subsurface imaging and the monitoring of changes thereof in response to geothermal or storage operations. The research covers induced earthquake source processes, how this relates to geology, and the geomechanical response of the subsurface. You are expected to present project results in reports, conferences and scientific papers.

Overall, a passion for the above topics, independence, ownership, dedication, and an inherent drive to take TNO’s knowledge, skills and project portfolio on this topic to the next level are what we are looking for.

You will work in multi-disciplinary projects, mainly with geophysics and geomechanics experts, but also with geologists, reservoir engineers, data engineers and other subsurface experts. Being proficient in English is a basic requirement as the team is composed of both national and international staff. You will help acquire new projects related to geophysical imaging and monitoring, and interact with both fundamental researchers as well as clients, industry and other relevant stakeholders.

What we expect from you

• An MSc in geophysics/geomechanics/seismology or related discipline.
• A strong interest in seismic monitoring, earthquakes, subsurface imaging and fiber optic sensing technologies.
• Basic knowledge of signal processing and geophysical data analysis.
• Experience and aptitude in coding and software development (preferably in Python).
• Strong analytical skills and enthusiasm for solving complex geoscientific challenges.
• Competent in writing high-quality academic texts as well as easy-to-read and concise reports, proposals, and grants.
• Able to work independently, responsibly, and result-driven.
• Proactive and willing to be an integral part of multi-disciplinary project teams engaging in topics beyond your own scope.
• Willing to aid in geophysical fieldwork and sensor deployment.
• Good communication skills.
• Interested in research as well as business-to-business (consultancy) projects.

What you'll get in return

Challenging and varied work with a real impact. And plenty of opportunities as, at TNO, you are in charge of shaping your career. We offer a gross monthly salary between € 3,500 and € 4,000 (based on your knowledge and experience), 8% holiday pay, a 13^th month bonus of 8.33% and a flex budget (5.58% + € 180). In addition, you will be given every opportunity to develop yourself.

Perhaps you would like to grow your career in the direction of commerce or consultancy? Or would you like to become a project manager? Immerse yourself in sustainable innovations? Or carve out a career as a technical expert?

TNO offers optional employee benefits, enabling you to tailor your benefits package to match your personal situation. You may also expect:

• An extremely professional, innovative working environment where colleagues are leading experts in their field.
• The opportunity to attend courses, workshops and conferences, and to receive training and coaching based on your needs.
• 33 days annual leave plus a flexible holiday that can be used on a cultural, religious, or otherwise important day of your choosing (on a full-time basis).
• An employer working towards a respectful, inclusive, and equitable work environment where every employee can flourish, with various initiatives such as Jong TNO, numerous expertise based guilds, Rainbow Community and Round Tables on diverse inclusion topics.
• We offer a comprehensive and flexible mobility plan that also includes full compensation for public transportation for commuting and business travel.
• Great social events with your team and other TNO colleagues. That’s how you will get to know a lot of people really quickly.
• Flexible working hours, the possibility to work parttime (32 or 36 hours) and the possibility of working from home.
• A good pension scheme.
