Python Software Engineer - Application Reengineering

Do you want to lead the transformation of a core Matlab application into a robust, user-friendly Python platform?

Project Details & Conditions:

Duration: 6-month contract, with a strong possibility of extension

Work Mode: Remote

Business Trips: To the Netherlands (initially weekly or bi-weekly, later adjustable)

We are seeking a skilled and self-driven Python Software Engineer to lead the re-engineering of a legacy Matlab 2013b application into a modern, modular, and maintainable Python-based platform; this application is a core tool for data processing, analysis, and visualization used in engineering and quality operations, and you will be responsible for designing the new architecture, ensuring long-term scalability, enabling offline and online use, and delivering a standalone, user-friendly executable that integrates with our existing PLM and LIMS systems.

Responsibilities:

• Re-engineer an existing Matlab 2013b application into a robust Python-based platform.
• Design a modular software architecture that supports plug-in data analysis and visualization modules.
• Develop a stand-alone application with a compiled executable to prevent source code manipulation by end users.
• Implement data import/export functionalities from/to PLM and LIMS systems (via Redshift connectors and file imports).
• Enable compatibility with various file types: .txt, .csv, .xlsx, .pdf, .jpg, .vbo, .vbb.
• Create a configurable UI to support different types of data views: tables, bar/column/line charts, and custom visualizations.
• Ensure code documentation and change tracking throughout the development lifecycle and post-release.
• Support both online and offline modes, including secure local data caching and syncing.
• Ensure the platform is maintainable by power users (e.g., engineers with scripting skills) without compromising core system integrity.
• Collaborate with internal stakeholders to define user requirements and validate outcomes.

Requirements:

• 7-10 years of relevant experience in Python
• Strong experience in Python software development, particularly for data processing and UI-heavy applications.
• Proven experience reengineering legacy codebases (Matlab to Python migration is a plus).
• Proficiency with modern Python frameworks for UI development (e.g., PyQt, Tkinter, Streamlit, or similar).
• Experience designing modular software architectures.
• Familiarity with data integration from enterprise systems (PLM, LIMS, Redshift, etc.).
• Solid understanding of data file handling and parsing for multiple formats.
• Knowledge of code compilation, version control (Git), and software packaging
• Fluent in English (spoken and written); ability to work with global teams.

Preferred Skills:

• Familiarity in engineering, data analysis, or quality systems.
• Familiarity with data visualization libraries such as Matplotlib, Plotly, Seaborn.
• Basic understanding of Redshift, SQL, and data lakes.
• Ability to write clear technical documentation and understand business requirements.
• Experience working in regulated or manufacturing environments.

Tools & Technologies You’ll Use:

• Languages: Python (primary), Matlab (for reference)
• UI: PyQt, Tkinter, or similar
• Data I/O: Pandas, openpyxl, PyPDF2, Pillow, etc.
• Database: RDS, MySQL
• Web API: FastAPI, Flask, Django
• Integration: SQLAlchemy, boto3, Redshift connectors, file watchers
• Version Control: Git, GitHub/GitLab
• Packaging: PyInstaller, Docker

You will love to join this company for:

• Opportunity to lead a high-impact reengineering project
• Collaboration with a cross-functional team of engineers and digital experts
• B2B contract
• Remote work with business trips to the Netherlands
• Work-life balance
