Customer Success Manager – LATAM (Reservoir & Digital Oilfield Leader)

Location: Buenos Aires, Argentina, and/or Bogotá, Colombia (Hybrid) 
Experience Level: Senior / Principal (10+ years) 

Role Purpose 

We are seeking a Customer Success Manager to lead Tachyus’ Customer Success strategy in LATAM. This is a leadership-heavy, high-visibility role designed for a Technical Consultant–Manager hybrid who combines deep Reservoir Engineering expertise with strong digital oilfield, project leadership, and change-management capabilities. 

This role goes far beyond traditional “support” or “delivery.” You will act as a trusted digital transformation advisor, responsible for identifying, fitting, and accompanying operators through their end-to-end reservoir management digital transformation journeys—from first technical adoption to enterprise-scale operationalization. 

The ideal candidate is someone who has run reservoir studies, challenged simulators, led multidisciplinary teams, and successfully driven the adoption of advanced digital workflows inside complex oil & gas organizations. 

Key Responsibilities

Executive Client Leadership & Digital Transformation Guidance

Serve as the senior technical and strategic authority for Tachyus’ most important LATAM accounts. 

Lead the definition of digital oilfield roadmaps, helping customers transition from traditional, siloed reservoir studies to closed-loop, operational reservoir management. 

Act as a trusted advisor to Reservoir, Production, and Asset Managers, as well as VP and C-level stakeholders, translating advanced physics-based AI models into business and operational outcomes. 

Lead executive-level workshops and steering committees, clearly articulating: 

Value creation 

ROI 

Change impacts on workflows, governance, and decision cadence 

Ensure Tachyus solutions are fit-for-purpose within each client’s Field Development Plans (FDP), reserves management processes, and operational constraints. 

High-End Reservoir Engineering & Technical Oversight

Provide hands-on technical leadership across projects involving: 

Reservoir management and surveillance 

Simulation-based forecasting 

Waterflood and EOR optimization 

Proxy / surrogate modeling 

Uncertainty quantification and optimization 

Challenge, validate, and contextualize complex dynamic models, including numerical simulators and fast physics-based AI models. 

Ensure technical rigor, predictivity, and defensibility of all results delivered to customers. 

Act as the final technical escalation point for complex reservoir or modeling questions. 

Software & Technical Stack 

Advanced fluency with industry-standard tools (Eclipse, Petrel RE, CMG, OFM, Sahara or equivalents). 

Strong understanding of model calibration, history matching, optimization workflows, and model uncertainty. 

Solid data analysis capabilities; SQL and/or Python experience is highly desirable. 

Program & Delivery Management (Strong Management Component)

Own end-to-end customer programs, managing scope, milestones, risks, and delivery quality. 

Apply structured project and program management discipline across multiple concurrent accounts. 

Lead cross-functional internal teams (Reservoir Engineering, Data Science, Product, Engineering). 

Use Jira and Confluence to enforce transparency, delivery cadence, documentation, and continuous improvement. 

Anticipate organizational, data, and adoption risks—and proactively mitigate them. 

Account Strategy, Adoption & Growth

Define and execute Customer Success Plans focused on adoption, embedded usage, and long-term value realization. 

Partner closely with Sales to identify expansion opportunities and convert technical wins into commercial growth. 

Drive renewals and minimize churn by ensuring measurable, defensible business impact. 

Actively help customers scale from pilots to enterprise deployments. 

Required Qualifications & Skills 

Seniority 

10+ years of experience in Reservoir Engineering, Reservoir Management, or Simulation. 

Exposure to both conventional and unconventional assets strongly preferred. 

Education 

Bachelor’s or Master’s degree in Petroleum Engineering, Reservoir Engineering, or Geosciences. 

PMP, Scrum, or advanced reservoir simulation certifications are a strong plus. 

Technical Excellence 

Deep expertise in reservoir modeling, forecasting, and optimization. 

Ability to critically assess and challenge models—not just run them. 

Strong understanding of production mechanisms, recovery processes, and operational constraints. 

Digital Oilfield & Transformation Skills 

Proven experience leading or supporting digital transformation initiatives in oil & gas. 

Strong intuition for where digital tools create value—and where they fail. 

Ability to guide customers through change, adoption, and workflow redesign. 

Management & Leadership 

Strong program/project management and stakeholder management skills. 

Comfortable leading multidisciplinary teams without formal authority. 

Structured, organized, and execution-oriented. 

Communication 

Exceptional executive communication and storytelling skills. 

Fluent in Spanish and English (mandatory). 

Able to communicate complex technical concepts clearly to non-technical executives. 

What We Offer 

Influence: You will be the face of Tachyus in LATAM, shaping how leading operators adopt AI-driven reservoir management. 

Innovation: Work at the intersection of reservoir physics, machine learning, and operational decision-making. 

Growth: A leadership role with real autonomy and visibility. 

Compensation: Competitive executive-level salary, equity (stock options). 

Culture: High-performance, multicultural, technically rigorous, and impact-driven.
