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
- 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
- Join a multicultural and inclusive team environment.
- Enjoy a supportive atmosphere promoting work-life balance.
- Engage in exciting national and international projects.
- Hybrid work.
- Your career growth is central to our mission. Our array of career growth programs and diverse professionals are crafted to support you in exploring a world of opportunities.
