AI Data Engineer

Position Purpose:

We are seeking a passionate and motivated AI Data Engineer to join our international team as part of a strategic expansion of our AI and Data capabilities.

In this role, you will be responsible for designing, building, and maintaining the data foundations that power foundational applications, advanced analytics, machine learning, Generative AI, and Large Language Model (LLM) applications across the organization. You will work at the intersection of data engineering, AI platform development, and data governance, ensuring that high-quality, trusted, and scalable data is available to support AI-driven innovation.

Your work will play a critical role in enabling next-generation AI solutions by building robust data pipelines, optimizing large-scale data architectures, and creating AI-ready datasets that support model training, retrieval-augmented generation (RAG), semantic search, and intelligent automation initiatives.

As an AI Data Engineer, you will collaborate closely with Data Engineers, Machine Learning Engineers, Data Scientists, Data Architects, Product teams, and business stakeholders to ensure that data assets are reliable, accessible, secure, and aligned with both business and technical requirements.

What You Will Be Doing

Design, develop, and maintain scalable data ingestion, transformation, and enrichment pipelines supporting AI and analytics initiatives.

Assess, modernize, and migrate legacy data platforms, tools, and operational processes to scalable, governed, and AI-ready data infrastructures.

Lead initiatives to replace manual, siloed, or obsolete data workflows with automated, cloud-enabled, and data-driven solutions.

Design and execute migration strategies for data assets stored in legacy applications, databases, file systems, and on-premise environments while ensuring data quality and business continuity.

Refactor and optimize existing ETL/ELT pipelines, data models, and integration processes to align with modern architectural standards and AI platform requirements.

Develop data processing solutions using Python, Spark, SQL, and distributed computing frameworks.

Design and implement data architectures supporting LLM-based applications, Retrieval-Augmented Generation (RAG), semantic search, and knowledge management platforms.

Develop and manage metadata, lineage, and cataloging solutions to improve data discoverability and governance.

Collaborate with Machine Learning Engineers and Data Scientists to provide high-quality feature stores, training datasets, and inference data pipelines.

Support the creation and maintenance of Data-as-a-Service (DaaS) platforms and reusable data products.

Implement automated data quality checks, validation frameworks, and monitoring solutions to ensure data integrity and reliability.

Contribute to AI platform engineering initiatives, including model-serving infrastructure, feature management, and AI data lifecycle management.

Ensure compliance with data privacy regulations, security standards, and organizational governance policies.

Define and implement best practices to ensure migrated systems comply with enterprise standards for data governance, security, lineage, observability, and documentation.

Participate in the design of AI governance processes related to data sourcing, quality management, access control, and responsible AI.

Collaborate with business stakeholders to identify opportunities for process automation, technical debt reduction, and platform modernization.

Stay informed on emerging technologies in data engineering, Generative AI, knowledge graphs, vector search, and AI platform architectures.

Participate in agile ceremonies including sprint planning, solution design reviews, architecture discussions, and continuous improvement initiatives.
