You'll pull data from operational source systems, build focused data pipelines to make it usable, and develop AI/ML models and GenAI integrations that turn that data into intelligent, working solutions.This role combines hands-on data engineering with applied AI. You'll build pipelines that are clean and fast enough to support rapid prototyping — structured using Medallion-style layering and dbt where appropriate — and you'll build and integrate AI models, LLM-based agents, and machine learning workflows that the team's applications consume. You work closely with Software Engineers who build the front-end experiences and Systems Analysts who define the requirements.Key ResponsibilitiesBuild Data Pipelines for PrototypingBuild focused data pipelines that pull from GPS source systems (SAP, MES, LIMS, planning tools, quality systems) and transform raw data into clean, usable datasets for prototypes and applications.Use Spark, Python, SQL, and AWS services (Glue, S3) to extract, transform, and load data efficiently.Apply Medallion architecture patterns (bronze → silver → gold) to organize data layers — keeping it practical and proportional to the prototyping context.Use dbt for modular, testable transformations where appropriate — build reusable models that the team can leverage across projects.Prepare curated datasets tailored for AI/ML feature engineering, application consumption, and analytical exploration.Develop & Integrate AI/ML SolutionsBuild and deploy machine learning models — predictive, classification, anomaly detection, and optimization models that support GPS use cases.Develop and integrate GenAI and LLM-based capabilities — including conversational agents, retrieval-augmented generation (RAG), and agentic AI workflows.Perform feature engineering — design and build feature sets from complex operational data that improve model performance and explainability.Work with Databricks for model development, experimentation, and deployment.Ensure AI outputs are structured and accessible for consumption by the team's web applications and user-facing tools.Collaborate Across the Digital LabPartner with Software Engineers to define data contracts, APIs, and output formats that applications need to consume.Work with Systems Analysts to understand business requirements and translate them into data and AI solution approaches.Engage with business stakeholders when needed to understand data sources, validate data quality, and confirm that outputs reflect operational reality.Coordinate with centralized IT / BI&T teams for access to source systems, data governance considerations, and handoff when solutions graduate to production scale.Keep It Practical and Prototype-ReadyBuild pipelines and models that are robust enough to support working prototypes and demos — not over-engineered for enterprise scale.Apply sound practices — version control, testing, documentation — proportional to the maturity of each project.Know when a pipeline or model is good enough for prototyping and when it needs to be hardened or handed off for production-grade implementation.Qualifications / EducationBachelor's or Master's degree in Computer Science, Data Science, Computer Engineering, Information Systems, or a related field.Experience & SkillsRequired5–7 years of hands-on experience in data engineering and/or applied AI/ML roles.Strong proficiency in Python, Spark, and SQL for data pipeline development and data manipulation.Experience with AWS cloud services — S3, Glue, Lambda, or equivalent — for building cloud-native data workflows.Hands-on experience with dbt for data transformation, testing, and documentation.Experience with Databricks for data processing, model development, or both.Working knowledge of Medallion architecture patterns (bronze/silver/gold layering).Experience building and deploying ML models — including feature engineering, model training, evaluation, and integration into applications.Exposure to GenAI and LLM patterns — RAG, prompt engineering, conversational agents, or agentic AI workflows.Comfortable working with messy, real-world operational data from multiple source systems.Strong communication skills — you can explain data and AI concepts to non-technical stakeholders and collaborate effectively with engineers.A pragmatic, prototyping mindset — you optimize for speed and usefulness, not perfection.Preferred / Nice-to-HaveExperience in pharma, life sciences, or manufacturing environments.Familiarity with GPS/PDS domain systems — SAP, MES, LIMS, planning tools (Kinaxis, Blue Yonder, or similar).Experience with React.js or Node.js — enough to build lightweight data-backed interfaces or APIs when needed.Experience with agent-based AI patterns, decision intelligence, or multi-step AI reasoning workflows.Familiarity with data quality frameworks and data lineage concepts.Experience working in innovation labs, prototyping teams, or fast-paced delivery environments.If
