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.

  • 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

  • Remote work with business trips to the Netherlands

  • Work-life balance
