With our ingenuity, drive and deep curiosity we discover new insights, innovations, and solutions that efficiently and responsibly resolve complex natural resource, digital, energy transition and infrastructure challenges.\nJob Summary\nThis six-month internship is designed for final-year physics, mathematics, and geophysics students eager to apply their theoretical knowledge and problem-solving skills to real-world Earth data.\nAbout the team\nWe are a diverse and dynamic group of around hundred of operation and R&D geophysicists based in France with strong relation with our colleagues from UK, Singapore, Brazil, and USA.\nWe develop and apply state-of-the-art signal processing, modeling, and imaging techniques using some of the world’s most advanced computing facilities to build high-resolution 3D images and models of the Earth’s subsurface. Beyond imaging, we transform seismic data into quantitative rock-property models, helping our clients better understand the subsurface and make informed decisions.\nYou can expect to develop your skill in the fields of signal processing, modelling and imaging, and to gain awareness of wider developments in the fields of geoscience and data science.\nKey Responsibilities\nYou will have the opportunity to work on one of the following topics:\nFWI for enhancing land imaging:\nFull-waveform inversion (FWI) has become an essential tool for velocity model building and imaging tool in marine environments, but its application on land seismic data remains challenging. Land FWI is hindered by elastic wave phenomena and complex near-surface conditions that generate energetic surface waves, scattering, mode conversions and multiples.\nWithin one of our teams dedicated to land seismic processing and imaging, during this internship you’ll be in charge of:\nTesting new methods to further refine and improve our current state-of-the-art FWI workflow, in collaboration with our R&D department\nSetting up a robust production FWI workflow over a large ultra-high-density land dataset\nTowards extracting reservoir properties with elastic FWI:\nFWI is widely used for velocity model building in complex geology. However, until recently, most industrial applications used acoustic modeling to reduce computing costs. Moving to elastic FWI is a step forward not only because it allows improving P-wave velocity and imaging, but also because it provides access to elastic parameters (Vp, Vs and density) which are critical for reservoir characterization.\nWithin one of our teams dedicated to marine seismic processing and imaging during this internship you will be in charge of:\nEstablishing a new imaging workflow for optimizing the update of the elastic parameters with FWI. The coupling between these parameters being a complex problem, testing will be carried out in collaboration with the R&D department\nBuilding a production-scale velocity model with elastic FWI over a streamer or OBN dataset.\nAdvanced 4D processing & Imaging:\n4D seismic processing and imaging are essential for monitoring how reservoirs change over time. By comparing seismic surveys acquired at different stages of production, they help to identify fluid movement, pressure variations, compaction, and possible subsidence. Careful processing is necessary to mitigate non-repeatable noise while preserving genuine reservoir-related signals. Moreover, accurate imaging places these changes at their correct geological locations.\nWithin one of our teams dedicated to processing and imaging of 4D monitoring data, you will oversee:\nDeveloping and testing novel signal-processing workflows to remove non-repeatable noise caused by 4D amplitude variations, positioning errors, and non-repeatable multiples between base and monitor datasets.\nRunning 4D imaging on a production-scale project and improving it by applying the process of least-squares migration to mitigate the impact of non-repeatable acquisition geometry.\nInnovative demultiple solutions for land seismic data:\nLand demultiple is a well-known challenge for land seismic imaging. The difficulty is due to complex near-surface conditions, irregular topography, variable source and receiver coupling, and high noise levels. These factors make multiple scattering difficult to separate from primary reflections using conventional demultiple methods and can then alter the quality of land seismic imaging. At Viriden, we work on improving the effectiveness of land demultiple for production projects.\nDuring this internship, you will be part of one of our teams dedicated to land seismic processing and imaging. You’ll be in charge of:\nTesting and deploying innovative demultiple methods and workflows in collaboration with our R&D department\nSetting up a robust production-scale workflow for a large ultra high-density land dataset with several hundred Terabytes of data\nQualifications\nLast year of Master’s degree in any of the following disciplines: Geophysics, Mathematics, Physics, Astrophysics/Astronomy, Natural Sciences with a Physics specialization.\nEnthusiastic attitude towards learning and passion for your subject\nThe technical ability to adapt your existing knowledge to a new field\nAbility to effectively communicate technical concepts\nEvidence of leadership, teamwork or customer service either from involvement in university societies/extracurricular activities, volunteering and/or work experience/internships\nBenefits\nCompensation depends on your internship contract.\nAccess to the company cafeteria at a subsidized rate.\nReimbursement of 50% of public transportation costs in Île-de-France (Navigo pass).\nAccess to company committee benefits (CSE advantages).\nHealth insurance, public transport partly covered.\nConfidential employee assistance program to support our staff covering mental health, counselling, wellbeing, legal & financial issues\nAdditional information\nStarting date: From January 2027\nOur Hiring Process\nAt Viridien, we are committed to delivering a respectful, inclusive, and transparent recruitment experience.\nDue to the high volume of applications we receive, we may not be able to provide individual feedback to every applicant. Only candidates whose qualifications closely match the role criteria will be contacted for an interview. We do, however, aim to share personalized feedback with those who progress to the first round of interviews and beyond.\nWe are also dedicated to ensuring that our hiring process accessible to all. If you require any reasonable adjustments to fully participate in the application or interview stages, please don’t hesitate to contact your recruiter directly.\nWe see things differently. Diversity fuels our innovation, we value the unique ways in which we differ, and we are committed to equal employment opportunities for all professionals.","description_format":"text","description_chars":6955,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":["Cafeteria","Health insurance"],"hiring_locations":[{"name":"France","iso":"FR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Consumer Goods","Furniture","Kitchens, Bathrooms & Home Improvement"],"lifecycle":[{"event":"open","at":"2026-10-05T20:49:47Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":11,"expected_fill_days":129,"reasons":["conf:30","velocity","win:early","comp:junior"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/viridiengroup-geophysicist-processing-intern","json_url":"https://alion.io/job/viridiengroup-geophysicist-processing-intern.json","meta":{"generated_at":"2026-10-17T13:27:13Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":18063,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":15283},"rest":"https://alion.io/mcp/rest/get_company?id=15283"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fviridiengroup-geophysicist-processing-intern"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fviridiengroup-geophysicist-processing-intern"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fviridiengroup-geophysicist-processing-intern"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/viridiengroup-geophysicist-processing-intern\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fviridiengroup-geophysicist-processing-intern"}]}
