Work Life Group NL

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
