INTERNSHIP - Data engineering & AI-ready software architecture

Job Description

The scientific problem

Every week, NMH experiments produce large volumes of heterogeneous measurements: plate-reader kinetics, microbiological assay readouts, imaging data, each in the native format of the instrument that produced it. Today, turning that raw output into an analysable result is largely manual :

• Experimental time is lost to data wrangling rather than to designing and running the next experiment.
• Results are hard to compare across campaigns , because the same biological variable is recorded differently depending on the instrument, the operator, and the date.
• Reprocessing a past experiment is difficult , which limits reproducibility and prevents the accumulated data from being reused to generate new hypotheses.

Internship goal: build a web interface in streamlit, python layer that takes raw instrument output to a clean, described, queryable experimental result and make that result directly consumable by modern AI architectures (LLMs, RAG pipelines, autonomous agents), so that a scientist can interrogate their own data in natural language.

Key responsibilities

• Instrument data acquisition & parsing: Design automated extraction modules capable of ingesting raw experimental data streams from various laboratory instruments and heterogeneous file formats, ensuring cleaning, typing, and quality control.
• Data standardization & schema modeling: Define and implement strict, unified data schemas (metadata, type validation, JSON serialization formats) to ensure data interoperability and reproducibility.
• Architecture: Structure datasets and develop tools/function calling endpoints, enabling AI agents or LLM/RAG pipelines to autonomously query, analyze, and manipulate standardized datasets.
• API & internal tooling: Expose processing services via REST APIs and build lightweight interfaces (e.g., Streamlit) enabling scientific teams to visualize, validate, and query data independently.
• Apply Biodata’s software engineering best practices: containerization (Docker), version control (Git), unit/integration testing, and technical documentation.

Expected deliverables

By the end of the internship you will deliver a deployed, operational standardization pipeline for at least one NMH data family; a documented experimental data schema; an LLM‑queryable access layer; and a lightweight interface used by the scientific team. Success will be demonstrated via a live demo, automated tests, deployment instructions, a short technical report, and readiness for inclusion in the supported scientific campaign.

Qualifications

Education

• Currently enrolled in a Master 2 or final year of Engineering School at a French university or higher French education institution (mandatory for the internship agreement / convention de stage).
• Must already hold valid authorization to work in France.
• Major in Computer Science, Software Engineering or Data Engineering.

Skills

Technical:

• Languages & data processing: advanced Python proficiency.
• Architectures & APIs: REST API design.
• Software engineering: Git, environment management, containerization concepts (Docker, TF).
• AI & data integration: data indexing concepts, databases, and LLM/agent integration patterns (function calling, JSON schemas).
• Appreciated: handling scientific and tabular data (units, dilutions, replicates, plate formats, time series), and any exposure to bioinformatics or laboratory data.

Mindset & interpersonal:

• Computer science / software engineering background. No prior biology background is required the scientific context will be provided by the research teams but genuine curiosity for microbiology and fermentation is expected: you will be modelling biological experiments, not generic records.
• Rigorous approach, strong abstraction skills, and commitment to code quality (Clean Code).
• Strong interpersonal skills for a multidisciplinary environment: you will sit with biologists and microbiota experts, understand how an experiment is carried out , and translate that into technical specifications

Languages: fluent English (written and spoken)

Additional Information

Desired starting date on January 2027, for a 6-months internship.
