Data Engineer (DBT) (m/f/d)

About the role

synvert,  a GlobalLogic company,   is a leading cloud, data, and AI services company, partnering with enterprises to design, implement, and manage end-to-end data and AI solutions that drive measurable business impact, combining deep technical  expertise  with strong industry knowledge across different sectors.                             As part of  synvert , in Portugal,  you’ll  join a team of experts pushing the boundaries of AI, Data, Product and Platform Engineering, working alongside an international, multidisciplinary team – all from our offices in Leiria, Lisbon and Viseu (so far!)!   As a  Data Engineer , you will be central to the migration effort — not a lift-and-shift, but a thoughtful, quality-driven transition that improves what already exists. Your responsibilities will include: Engage with dataset owners across the business to understand what data exists, how it's used, and what needs to be migrated
Assess current ingestion pipelines for correctness and reliability
Map downstream dependencies before migrating any dataset
Identify and flag PII fields across datasets, ensuring the new platform meets security, compliance, and legal requirements from the outset
Review each pipeline critically during migration — not just reproduce it: Spot and fix bad joins, poorly structured queries, and unnecessary complexity
Consolidate intermediate datasets where possible (e.g. reducing 4 staging layers to 2)

Write data quality tests covering null checks, source-to-destination validation, and volumetry
Set up monitoring and alerting infrastructure, with a view to supporting future on-call rotations via PagerDuty and Slack
Validate that outputs from the new platform match the old platform before any decommissioning takes place
Key Requirements:   At least 3 years of experience in data engineering roles
Advanced, hands-on dbt experience
Solid experience with infrastructure-as-code, ideally Terraform 
Strong SQL skills and a good eye for query performance
Practical experience with AWS, particularly S3; familiarity with Athena and MSK is a plus
Fluent English and strong communication skills — you'll be working with non-technical stakeholders and dataset owners regularly
A methodical approach to data quality, compliance, and documentation
Nice to have:   Experience with Snowflake
Experience with Fivetran
Resilience and the ability to navigate change and adapt
Experience working in a fast-paced start-up environment
Experience developing solutions using Generative AI, LLMs, or agentic architectures
Experience leveraging AI-powered SDLC workflows for both product and engineering tasks
