CAPGEMINI ENGINEERING
At Capgemini Engineering, the world leader in engineering services, we bring together a global team of engineers, scientists, and architects to help the world’s most innovative companies unleash their potential. From autonomous cars to life-saving robots, our digital and software technology experts think outside the box as they provide unique R&D and engineering services across all industries. Join us for a career full of opportunities. Where you can make a difference. Where no two days are the same.
YOUR ROLE
You will design and run pipelines that map messy, multi-source data to canonical models, standard identifiers and controlled vocabularies, and you will make sure the result is trustworthy, documented and ready for analytics, knowledge graphs and AI use cases. You are the person scientists and data engineers rely on to turn raw data into something they can query and trust.
Key responsibilities
Build and maintain Python and SQL pipelines for data manipulation, transformation and integration across multiple sources
Define and implement source-to-canonical mappings, persistent identifiers and vocabulary alignment
Design and automate data quality assessment: completeness, validity, consistency, uniqueness and provenance checks
Normalize entities (genes, diseases, phenotypes, compounds, tissues) against authoritative identifiers and ontologies
Work with scientists, data engineers and product teams to translate scientific needs into data requirements
Document mappings, modelling decisions and validation rules, and keep them in version control
Investigate and resolve data issues at the source, and communicate their impact
Mentor junior colleagues and review their code and mappings
YOUR PROFILE
MSc or PhD (or equivalent professional experience) in biology, biomedical sciences, bioengineering, genetics, neuroscience, bioinformatics, computational biology or a related field
3 to 5 years of experience in data engineering, bioinformatics or scientific data work, with real biomedical datasets
Strong Python (pandas or similar) and SQL skills, with pipelines you built and maintained
Hands-on experience with data harmonization & mapping, vocabulary alignment and persistent identifiers
Experience with data quality assessment and validation frameworks, with checks written as code
Solid Git practice & branches, pull requests, meaningful commit history
Biological reasoning about the data you handle (genes, variants, diseases, phenotypes, assays)
Clear communication with scientific and technical stakeholders
Fluent English
Preferred qualifications:
Experience with biomedical ontologies and databases such as Gene Ontology, MONDO, HPO, EFO, UBERON, ChEBI, Ensembl or UniProt
Agentic AI experience & LLM-based agents or workflows, tool use, retrieval-augmented generation, or LLM-assisted curation and mapping, with validation of the output
Validation frameworks (Great Expectations, Pandera, SHACL or similar)
Workflow orchestration (Airflow, Prefect, Snakemake, Nextflow) and Docker
Cloud platform experience (AWS, Azure or GCP)
Knowledge of schema modelling (LinkML or equivalent), FAIR principles, RDF or SPARQL
Applied machine learning
Experience in pharma, biotech or another regulated research environment
Portuguese fluency
What we look for:
Scientific curiosity paired with engineering discipline
Critical thinking and attention to data provenance and quality
Comfort with ambiguity, and the ability to move between scientific meaning and technical implementation
An impact-driven mindset in a fast-paced environment
