Purpose:

We are seeking a Data Scientist and Application Developer to join a cross-functional team of engineers and scientists delivering data-driven solutions tied to manufacturing. In this role you will alternate between building business applications that enable fast, iterative analytics and operationalizing models that directly inform product quality decisions in a GMP context.

You will be responsible for:

Application Development (GMP + non-GMP)

• Build and maintain internal web applications that make analytics usable in day-to-day workflows.
• Develop services using Python with Flask (and/or FastAPI where appropriate), including: Lightweight APIs for data access and model execution User-facing interfaces using Flask + Jinja, with small amounts of JavaScript and optionally React for richer interactions.
• Implement pragmatic software engineering practices (modular design, testing, logging/monitoring hooks, clear documentation) aligned to intended use (GMP vs non-GMP).

Data Science & Modeling (Manufacturing Context)

• Apply strong fundamentals in statistics, data extraction + cleaning, and modeling to diverse manufacturing datasets (e.g., batch/process time series, quality data, laboratory and instrument outputs).
• Develop, evaluate, and document models intended to support insights into manufacturing performance in a GMP environment, focusing on interpretability and lifecycle considerations.
• Collaborate with engineers, scientists, and quality partners to define the problem, select fit-for-purpose methods, and translate outcomes into operational decisions.
• Communicate findings clearly to technical and non-technical stakeholders; create reusable analysis patterns and templates.

Delivery Practices & Collaboration

• Use git fluently in a team setting (branches, pull requests, code reviews).
• Contribute to maintainable, supportable solutions on an internal hosting platform; collaborate with platform/IT partners as needed.
• Follow good documentation and change practices appropriate to regulated and non-regulated use, ensuring solutions are understandable and auditable when required.

Qualifications / Requirements:

Required Qualifications

• Bachelor's degree (or higher) in Data Science, Statistics, Computer Science, Engineering, or related field (or equivalent practical experience).
• Strong data science fundamentals: Basic statistics and experimental reasoning Data wrangling and exploratory analysis Model building and evaluation.
• Strong Python skills for both analysis and application development.
• Familiarity with basic SQL fundamentals is required.
• Experience building user-facing applications using Flask (templates/Jinja) and familiarity with basic front-end concepts (HTML/CSS/JavaScript).
• Comfort working with diverse, imperfect datasets and iterating toward robust solutions.
• Strong collaboration and communication skills in a cross-functional environment.

Preferred Qualifications

• Familiarity with FastAPI and API design concepts (can be learned on the job if needed).
• Experience supporting software or analytics in regulated/GMP-like environments (validation mindset, documentation discipline, traceability).
• Exposure to manufacturing, pharma, chemical, or other industrial process data.
• Knowledge of Azure services and/or identity concepts (e.g., Entra ID) is a plus but not required.
• Familiarity with containerization/DevOps practices (e.g., Docker, CI/CD) is helpful.
