An exciting opportunity to join an international gold mining group as a Geoscience Data Engineer in either Abidjan or Dakar. Our client is looking for candidates who can combine a strong data engineering background with experience in geoscience.

Our client is strengthening its enterprise management of exploration and geoscience data to accelerate discovery, improve decision quality, and enable advanced analytics and AI.

As part of this journey, they are recruiting a Geoscience Data & Automation Engineer who will play a critical role in industrialising exploration data flows across all sites. The position is accountable for designing and maintaining automated systems, data transformation, and quality control pipelines for drilling, logging, sampling, assay, survey, and geospatial datasets.

The objective is to eliminate manual uploads, spreadsheet dependency, and fragmented QA/QC processes, while ensuring that exploration data is structured, historised, reliable, and analytics-ready.

The role contributes directly to AI-readiness by enabling clean, standardised, and scalable exploration datasets to be consumed by geological modelling, analytics, and machine learning initiatives.

Key responsibilities

Design, build, and maintain end-to-end automated data exchanges for exploration systems,

including:

● Drilling and logging systems (e.g., LogChief, IMDEX), Assay laboratory datasets (CSV, XML, API-based feeds)

● BoxScan imaging datasets

● Survey and geospatial datasets

● Central Geoscience Data Management Systems (GDMS)

● Ensure secure, scalable, and reliable data flows from field systems to the enterprise

data platform.

● Reduce manual handling and eliminate duplicate or inconsistent data uploads.

Data Transformation & Historicisation

● Implement transformation logic to standardise, harmonise, and historise exploration

datasets.

● Ensure data models support longitudinal analysis, geological interpretation, and AI-driven use cases.

● Maintain clear separation between raw, curated, and analytics-ready datasets.

Design and implement automated QA/QC checks across exploration datasets, including:

● Drillhole validation rules, Assay consistency checks, Referential integrity controls

● Schema validation and completeness checks

● Monitor data quality metrics and collaborate with site geologists and QA/QC managers to resolve data issues.

● Ensure datasets are certified before use in resource modelling or advanced analytics.

Collaborate with Enterprise Architecture and Data Platform teams to:

● Integrate exploration systems with the central data platform

● Ensure metadata, lineage, and documentation standards are respected

● Design scalable and resilient data pipelines, Implement monitoring, logging, and incident resolution mechanisms.

● Support hybrid architectures where required (site systems + cloud platform)

Data Capture, Validation & Quality Assurance

● Design and supervise data capture workflows from field to system: site geologists, samplers, contractors.

● Implement automated QA/QC processes to ensure data accuracy, completeness, and consistency.

● Coordinate with: Regional Exploration QA/QC Managers, Site Data Stewards / Field Geologists, GISGeologists, to ensure data is validated at each stage before use in interpretation or modelling.

Collaboration & Stakeholder Enablement

Work closely with:

● Site geologists and data stewards

● Regional Exploration QA/QC Managers

● GIS geologists

● Data Scientists and Data Engineers
