The role also follows ITIL, security, and operational standards while developing skills in automation, cloud computing, and HPC technologies.

Conduct research on neural-network methods for incorporating petrophysical information into reservoir-oriented Full-Waveform Inversion. Develop models mapping porosity, lithology, and saturation to elastic parameters, then integrate them into FWI workflows. Collaborate with subsurface imaging R&D, software, and production teams while applying machine learning, wave propagation, signal processing, and numerical optimization to Earth imaging challenges.

Deploy and operate secure, scalable agentic AI, LLM, and vision-language applications across cloud, on-premises, hybrid, and restricted environments. Responsibilities include integrating AI systems with enterprise APIs and data platforms, building connectors and deployment workflows, implementing security and observability, optimizing reliability and performance, and troubleshooting production systems across application, infrastructure, network, and data layers.

Entry-level IT support role for a graduate joining a global HPC team. Responsibilities include monitoring and maintaining Linux, HPC, cloud, and IT platforms; troubleshooting incidents; supporting automation and system improvements; documenting procedures; collaborating with technical teams; and following IT service management, security, and change-control processes. The role provides structured coaching and hands-on development across Linux administration, cloud technologies, DevOps, scripting, and infrastructure automation.

Supports internal audit engagements across operational, compliance, and entity reviews. Responsibilities include testing controls, analyzing processes, documenting audit work, identifying improvements, preparing reports, presenting findings, and supporting initiatives that enhance audit methodologies, quality, and tools. The role requires strong finance and accounting knowledge, analytical and investigative abilities, French and English proficiency, and current enrollment in a relevant master’s or business program.

The Compensation Specialist analyzes market and internal pay data, maintains salary structures and incentive programs, supports benchmarking and compensation cycles, models costs for offers and program changes, administers incentive plans, ensures pay compliance, and advises HR, Finance, Talent Acquisition, and managers on compensation policies and decisions.

Develop and maintain desktop graphical applications for 3D subsurface imaging. Implement core components, backend data handling, user-facing features, and 3D visualization. Support builds, testing, releasing, debugging, performance optimization, and cross-team collaboration in large-scale computing environments.

Work on backend services, APIs, ML model deployment, debugging, performance tuning, containerization, and development workflows. Collaborate on system design, write clean code, and support deployments across teams.

Design and build scalable data-transformation and processing pipelines, collaborate with SMEs and labeling teams, support annotation workflows, maintain version control, run experiments, and train or fine-tune ML models (including LLMs). Troubleshoot data issues, contribute to data integration, feature design, and document learnings to align with production and technology teams.

Process and analyze seismic data to produce accurate 3D subsurface images. Test and optimize imaging workflows, perform quality control, collaborate with scientists and developers, contribute to publications, and support client projects with technical seismic insights.

Design, develop and evaluate single- and multi-agent AI systems integrating LLMs, vision-language models and tools. Implement planning, memory, tool-use, RL/fine-tuning, training environments, reward functions and monitoring, and convert prototypes into production-ready APIs and services.

Develop and maintain high-performance geophysical algorithms for seismic processing, imaging, and interpretation. Optimize and parallelize code for GPU and CPU HPC architectures (MPI/CUDA), participate in design, deployment, and lifecycle management, and work with a distributed team to ensure scalable, reliable software.
