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.
