Job Description:

Join us as a Backend Software Developer (Intern) and take part in building a powerful pre-sales engineering tool that brings together technical calculations and commercial intelligence into a seamless web application. This tool supports the planning and proposal of energy-efficient solutions by integrating cooling load estimation, energy savings, investment costs, ROI, and profitability — all wrapped into a professional, user-friendly platform.

If you're excited about building tools that drive sustainable decisions and want to see your code applied in real-world commercial settings, this role offers an incredible learning experience.

Key Responsibilities:

Web Development & Integration:

• Help build and maintain the backend logic of a full-stack web application using Python.
• Collaborate on integrating complex engineering calculations and financial models into the application.
• Connect the backend to modern front-end components and enable responsive, data-driven user interfaces.
  
  
  

Data & Application Design:

• Contribute to structuring and managing user data, system inputs, and generated outputs using appropriate databases.
• Assist in designing user authentication, role-based access, and data security features.
  
  
  

Tools & Systems Integration:

• Explore and implement integration points with spreadsheets, APIs, and other platforms to streamline workflows.
• Support version control, testing, and deployment processes using Git and modern DevOps tools.
  
  
  

Required Skills:

Programming & Problem-Solving:

• Strong foundation in Python and backend development concepts.
• Basic experience with front-end technologies (HTML, CSS, JavaScript).
• Understanding of databases (SQL or NoSQL) and API development.
  
  
  

Eagerness to Learn:

• Curiosity about how real-world systems are engineered and priced.
• Willingness to experiment, prototype, and learn from feedback.
  
  
  

Collaboration & Communication:

• Ability to write clear, structured code and documentation.
• Comfort working in a collaborative team environment, participating in reviews, and sharing ideas.
  
  
  

Preferred Qualifications:

• Familiarity with frameworks such as Flask, Django, or FastAPI.
• Experience using tools like Pandas or openpyxl to handle spreadsheet data.
• Exposure to GitHub, REST APIs, or cloud deployment platforms (e.g., Heroku, Vercel).
• Interest in energy systems, sustainable design, or technical sales tools.
