To strengthen our team in Wietmarschen-Lohne we are looking for a

Customer Project Manager (all genders welcome) - Upstream Optimization

You will own end-to-end delivery of our Upstream Optimization "Optimization as a Service" (OaaS) projects for oil and gas operators, translating signed contracts into successful, referenceable field deployments. Working at the interface of the customer, our technical/product teams and sales, you ensure that our AI-driven, real-time production and reservoir optimization solutions built on clamp-on multiphase flow sensing and top-down reservoir modelling are implemented on time, on budget, and deliver production and recovery gains to our customers.

What you can expect

• Act as the primary point of contact for the customer from contract handover through implementation, value validation, and expansion/renewal, building trusted relationships with subsurface, production, digital, and operations stakeholders.

• Plan and manage the full project lifecycle - mobilization, sensor and system installation, data integration, model calibration, optimization cycles, and reporting against agreed scope, timeline, and budget.

• Coordinate cross-functional delivery teams (reservoir engineers, data scientists, field/instrumentation specialists, software engineers) to keep workstreams aligned and on schedule.

• Own project governance: risk and issue management, change control, status reporting, and steering committee updates for both the customer and internal leadership.

• Track and report on technical and commercial KPIs to demonstrate value delivered and support performance-based contract terms.

• Manage on-site data-sharing and execution commitments with the operator, ensuring timely access, validation support, and implementation of recommended actions.

• Identify scope changes, upsell, and expansion opportunities within existing accounts and feed them back to sales and account management.

• Provide structured field and customer feedback (technical performance, operational constraints, competitive intelligence).

What you bring

To become part of the Rosenxt family, you have a customer-oriented, structured and solution-driven way of working. You should also bring:

• Degree in Petroleum Engineering or a closely related discipline; an advanced degree (MSc/PhD or PMP/project management certification) is a plus.

• 7+ years of experience in the upstream oil and gas industry, including meaningful exposure to production optimization, reservoir management, or field development.

• Proven track record managing complex, technical, customer-facing projects — ideally involving digital oilfield, real-time monitoring, or data-driven optimization solutions.

• Solid understanding of production systems, artificial lift, injection strategies, and reservoir management, with the ability to engage credibly with subsurface and production engineers.

• Strong stakeholder management skills, able to operate confidently from field engineering teams up to VP, and to manage tri-partite arrangements involving customers and subcontractors.

• Excellent organizational skills: budgeting, scheduling, risk management, and reporting discipline across multiple concurrent projects.

• Willingness to travel internationally to customer sites, including in EU, Middle East, and Asia Pacific regions.

• Fluency in English; additional languages are an advantage.

• Reports to the Business Area Manager Upstream Optimization, with close coordination with sales, product, and technical leadership.
