Your Mission
What You'll Do
Main responsibilities
- Ingestion pipelines: design, build and run pipelines that bring clinical, preclinical and device data (neural recordings, video, sensor and clinical metadata) from study sites into the AWS/Iceberg platform.
- Data quality: put automated checks in place for completeness, format, required metadata and signal quality (e.g., SNR, impedance), and make failures visible and routed to an owner.
- Curation and modelling: turn raw data into standardised and curated, analysis-ready datasets in Snowflake (raw → standardised → curated), versioned and documented.
- Data Contracts: apply Data Contracts at ingestion, working with Clinical and study sites; reject non-conforming data rather than fixing it silently.
- Traceability and lineage: keep a full path from every dataset back to its source site, study, session and Data Contract version, to meet ALCOA+ and 21 CFR Part 11 requirements.
- Catalog and access: register datasets in the catalog with owner, source, metadata and access classification, and support role-based access for data users.
- Enabling ML and analytics: provide reproducible, versioned datasets to the ML Ops and data science teams, including the reference datasets used for model training and validation.
- Scaling to new data: onboard new studies and data types using reusable patterns, including the high-volume semi-chronic and chronic recordings from 2027–2028.
- Standards and documentation: define data engineering standards and SOPs and document pipelines for audits and regulatory submissions.
- Collaboration: work with the Platform Architect, DevOps and MLOps engineers on the platform, and with Clinical, Translational Science and RA&QA on data requirements.
What You'll Bring
Education
- BSc or MSc in Computer Science, Systems Engineering, Mathematics or a related technical discipline.
- Over 5+ years in Data Engineering, with at least 2 in a senior role designing and owning production pipelines.
- Strong Python and SQL.
- Hands-on experience with AWS, especially S3, IAM, Glue and compute services.
- Experience with a modern Lakehouse or Warehouse stack: Apache Iceberg (or Delta/Hudi) and Snowflake (or a similar warehouse).
- Experience building ingestion and transformation pipelines with an orchestrator such as Dagster or Airflow.
- A track record of automated data-quality checks, data versioning and lineage.
- Comfort with IaC (Terraform/OpenTofu), Git and CI/CD.
- Fluent English, written and spoken.
- Experience in a regulated environment such as medical devices, pharma, clinical trials or healthcare: GxP, ALCOA+, 21 CFR Part 11, ISO 13485.
- Experience with clinical or biomedical data, such as EDC/eCRF exports, CDISC (SDTM/ADaM), or de-identified patient data under GDPR/HIPAA.
- Experience with time-series or signal data, ideally neurophysiology (NWB, BIDS, HDF5), or large sensor and video datasets.
- Experience with data contracts or schema-as-code.
- Experience supporting ML teams with reproducible, versioned training datasets.
- Ownership: takes a pipeline from design through to operation.
- Explains data issues clearly to scientists, clinicians and quality teams.
- Documents work so that it holds up in an audit.
