Application Developers are at the core of a business. What are their responsibilities?

Application developers are a fundamental part of any tech team. They are responsible for using their knowledge of programming languages to design software applications. 

Their duties include analyzing user needs and software requirements to determine the feasibility of design within time and cost constraints, coding and testing software to ensure functionality and updating software application to refine components. 

What Skills Will You Learn During Your Training? 

We’ll guide you at the beginning of your application development journey, helping you to set up a solid foundation for your training. You’ll discover software programming with one of the easiest languages to learn: Python.

Over the course of this training program, we'll teach you a variety of skills, including how to:

  • Interpret the client's needs and create a prototype.
  • Apply the fundamentals of programming in Python.
  • Manage data using ETL (extract, transform, load).
  • Use object-oriented programming to develop a Python program.

In addition to these technical skills, you’ll learn transversal or "soft" skills, which will help you grow in your career.

How Do OpenClassrooms Apprenticeships Work? 

Apprenticeship programs combine paid on-the-job learning with online project-based instruction that equips employees for high-demand careers in data, technology, and business development.

Here’s how it works:

  1. Onboarding (2-3 weeks prior to start of apprenticeship): Familiarizes both the apprentice and the employer with the training components and requirements. 
  2. Pre-apprenticeship (3 months of training): Provides the apprentice with scenario-based project learning coupled with weekly mentorship and skills building courses in preparation for the formal apprenticeship program.
  3. Apprenticeship (12 months on-the-job, with one day per week of instruction): Continues to build apprentice’s skills via on-the-job training, corresponding online instruction, and weekly one-to-one mentoring sessions. 
  4. Get certified! Following completion of the apprenticeship program, apprentices earn an industry-recognized and nationally portable credential from the U.S. Department of Labor. 

Online But Never Alone! 

Before, during, and after the training program, you’ll be accompanied by humans:

  • One-to-one weekly mentorship sessions with a professional in the field, in partnership with OpenClassrooms, who’ll provide you with support and guidance to complete your projects.
  • OpenClassrooms staff who’ll help you succeed in your apprenticeship.
  • Our global community of student peers with whom you’ll be in regular contact through our online platform.

“Sometimes students are afraid that others will judge them, or simply afraid of failing. My role as a mentor is to remind them that they’re in training, and they’re here to try as many things as possible. The more they try, the more feedback they’ll get on their work. This approach feeds their curiosity and helps them to go faster!”
