To strengthen our team in Wietmarschen-Lohne we are looking for a Product Owner (all genders welcome) - AI-Driven Reservoir Simulation & Optimization based in Germany, UK or the Netherland. Upstream optimization, an innovative division of the Rosenxt Group, which was spun off in 2023 and is dedicated to expanding into new business areas. Our focus is on developing advanced technologies for the optimization of energy production. Our state-of-the-art flow measurement device is a clamp-on non-intrusive system, gathering extensive real-time operational process data. In our interdisciplinary, agile, and autonomous teams, we foster innovations and customer value. As Product Owner, you lead the development of our AI-driven reservoir simulator. This next-generation digital product combines machine learning with real-time and historical production data to model, predict and optimize reservoir performance. You connect reservoir engineers, data scientists, software developers and business stakeholders, and you turn complex technical and commercial requirements into a clear, prioritized product backlog and roadmap. What you can expect Own and continuously refine the product vision, roadmap, and backlog for the AI-driven reservoir simulator, aligned with business goals and market demands. Translate reservoir engineering and production-optimization requirements into clear user stories, acceptance criteria, and well-defined epics for cross-functional development teams. Collaborate closely with reservoir engineers, data scientists, and software/DevOps teams to ensure the AI model architecture is developed with production-grade data pipelines and validated against real reservoir behavior Define and prioritize features covering data ingestion and preprocessing (data cleaning, integration, transformation, aggregation of high-frequency sensor and low-frequency reservoir data), model training, history matching, and production forecasting and further reservoir optimization features. Facilitate sprint planning, backlog refinement, reviews, and retrospectives in an agile/Scrum environment in alignment with the extended project team; track progress against OKRs and epics. Act as the primary point of contact between internal stakeholders (engineering, commercial, leadership) regarding product scope, timelines, and value delivery. Define and monitor KPIs for model accuracy, computational performance, and business value (e.g., incremental production, reduced simulation runtime, improved forecast accuracy). Stay current on AI/ML advances in reservoir simulation (e.g., neural network surrogates, generative AI assistants, automated history matching) to keep the product roadmap competitive. Option to work remotely in countries Rosenxt bases like Germany, UK or the Netherland What you bring To become part of the Rosenxt family, you have an analytical, structured and solution-oriented way of working. You should also bring: A degree in petroleum engineering, reservoir engineering or a related technical field, or equivalent practical experience. 5+ years of experience as a Product Owner, Product Manager or similar role in a software or data-driven product environment with experience in oil & gas industry. Solid understanding of agile methodologies (Scrum/Kanban), backlog management, and tools such as Azure DevOps. Deep knowledge of reservoir engineering concepts (multiphase flow, production data, history matching). Basic understanding of AI/ML concepts (e.g., neural networks) sufficient to engage credibly with data science teams; hands-on ML experience is a plus. Strong stakeholder management and communication skills, able to translate between technical, commercial, and executive audiences. Experience with data aggregation and modeling challenges across different frequencies (real-time sensor data vs. monthly/quarterly reservoir data) is a plus. Fluent in English (written and spoken); German language skills are an advantage. Look forward to Development opportunities and career opportunities in a global, innovative and long-term oriented group of companies with family character Flexible working time and Home Office possible An open, informal corporate culture, where we celebrate success with social events Compatibility of work and family through our company-owned day care center Employer funded pension, capital accumulation benefits and discounted insurance offers (occupational disability insurance and other direct insurance policies) Company Restaurant (only in Wietmarschen-Lohne) Various in-house sports activities (EGYM Wellpass and other offers) Discounted charging facilities for electric vehicles directly at the company location Attractive leasing offers for IT-products and bikes for private use Corporate Benefits - employee offers in changing online shops at top conditions More information about the Rosenxt Group please click here: www.rosen-nxt.com Rosenxt is a forward-thinking technology group — we are visionary architects of progress with decades of engineering excellence. As a privately owned global partner with more than 740 employees, we look far beyond tomorrow: being committed long-term, we turn opportunities into successful ventures. Tech enthusiasts through and through, we dive deep into the latest technologies. Our expertise in various technology fields such as sensors, autonomous robotics, AI, and advanced materials combined with our strong R&D mindset, allows us to develop high-tech solutions for customers in the most challenging environments, including subsea, industrial, renewables, and the integrity of the water and energy supply. Our purpose goes beyond pure business: it is about creating progress and sustainable value – for our customers, for our partners and for society at large.
