FAQ about the software developer

What is the difference between a software developer and a web developer?

A web developer focuses on browser-accessible applications (websites, front-end and back-end web apps). A software developer has a broader scope: they can build desktop applications, embedded tools, business software, or operating systems. In practice, the two terms are sometimes used interchangeably, but software developer covers a wider range of program types.

What is the salary of a software developer in France?

In France, a junior software developer typically earns between €35,000 and €50,000 gross per year. A mid-level profile ranges from €45,000 to €70,000, and a senior can reach €60,000 to over €100,000 depending on the sector, company size, and technologies mastered.

What training is needed to become a software developer?

A software developer typically holds a Bachelor's to Master's-level degree in computer science, software engineering, or mathematics. Engineering schools, university technology institutes (IUTs), and undergraduate/graduate programmes are the most common paths. Bootcamps and online courses also provide an alternative entry route, especially for career changers.

What programming languages does a software developer master?

The most common languages are Java, C++, Python, C#, JavaScript, and Swift. The choice of language depends on the type of software being built: Python is favoured for data and AI, Java and C# for enterprise applications, C/C++ for embedded systems and high-performance software. Mastery of several languages is a major asset.

What are the day-to-day responsibilities of a software developer?

Day to day, they analyse user needs, design their solution's architecture, write and test code, fix bugs, and maintain existing software. They usually work in teams following agile methodologies (Scrum, Kanban) and take part in code reviews, sprint meetings, and exchanges with product and QA teams.

What tools does a software developer use?

They use IDEs such as Visual Studio, IntelliJ, or VS Code; versioning tools like Git; CI/CD tools (GitHub Actions, Jenkins); dependency managers (Maven, npm); and stack-specific frameworks (Spring, React, Django…). Project management tools like Jira or Linear are also part of daily work.

How does a software developer's career evolve?

After a few years of experience, a software developer can progress to lead developer, software architect, tech lead, or technical project manager. Some specialise in cybersecurity, cloud, or DevOps. Others move into management as engineering manager or CTO. Freelancing is also very common in this field.

What is the difference between a software developer and a software engineer?

In practice, the two titles often describe the same role. Historically, "software engineer" implies a more rigorous, formalised approach (design, architecture, documentation), while "software developer" is more broadly associated with writing code. In French tech recruitment, the two terms are used almost interchangeably — the difference is mainly cultural or company-specific.
