Software test engineer

‍I - What does a software test engineer do?

The software test engineer (also called software test engineer) intervenes during the development cycle with a clear objective: to guarantee the quality, stability and performance of applications before they are put into production. Ensuring software reliability, it intervenes at all stages of technical validation.

Definition of the role

The software test engineer is responsible for verifying that the product developed corresponds to the initial specifications and meets the expectations of the end users. It is not simply a question of “looking for bugs”, but of setting up a structured approach to prevent anomalies, ensure compliance, and improve the user experience.

On a daily basis, he works in close collaboration with developers, of project managers and sometimes even customers, to ensure that every feature delivered is tested, validated and documented.

Main missions

The missions of a software test engineer vary from one project to another, but the following missions are generally found:

• Needs analysis : Understand functional and technical requirements to define the most appropriate test strategy.
• Writing test plans : Develop accurate scenarios (functional tests, non-regression tests, performance tests, etc.).
• Executing tests : Launch test campaigns, manually or using automation tools, depending on the level of complexity of the project.
• Detection and follow-up of anomalies : Identify anomalies, document them clearly and work with development teams to correct them.
• Continuous improvement : Ensure the optimization of quality processes, propose more effective test methods, and contribute to the evolution of best practices.

In an agile or DevOps environment, the engineer is often integrated from the early stages of the project to anticipate points of vigilance and shorten delivery times while maintaining a high level of quality.

II - What are the skills required to do this job?

This profession is based as much on technical mastery as on real intellectual rigor. To succeed in this job, certain skills are essential, whether technical or behavioral.

Technical skills

To successfully carry out his missions, the software test engineer must master a certain number of tools, languages and methodologies. Among which are:

• Knowledge of test tools : Selenium, Postman, TestLink, JIRA, SoapUI or even suites like HP ALM or Xray.
• Test automation : Writing automated test scripts with languages like Python, Java or JavaScript.
• Development methodologies : Understanding the V-cycle, Agile or DevOps.
• CI/CD concepts : Understand how tests can run automatically with each code change, using tools like Jenkins or GitLab CI. This makes it possible to identify bugs quickly and to deliver reliable versions of the software more often.

Soft skills

Technical skills alone are no longer enough; human qualities make the difference. A successful engineer must:

• Demonstrate rigor and organization : Tests should be repeatable, traceable, and documented.
• Have a spirit of analysis and synthesis : Identify the cause of a bug, prioritize critical anomalies, structure an effective test plan.
• Communicate with clarity : To be able to report anomalies constructively and to dialogue with various profiles: developers, project managers, sometimes even customers.
• Be curious and proactive : The test engineer is often the one who asks the “right questions” technical questions, those that we did not necessarily anticipate.
• Working as a team : As seen above, this job requires working with various IT teams. It is therefore necessary to know how to be adaptable.

Being a software test engineer at IT Link means playing a role in the reliability of the solutions we design. Understanding, questioning, collaborating: so many reflexes that make a difference in the field.

III - What studies or training courses to become a software test engineer?

This profession is accessible via various training courses, with a focus on computer science, software engineering or embedded systems. The important thing is to gain a solid understanding of development processes, programming languages, and the fundamentals of software testing.

A bac + 5 course, the most frequent way

The majority of software test engineers come from a Bac + 5 course, including:

• Engineering schools in computer science or electronics, generalists or with a specialization in software quality, validation or embedded systems.
• Master's degrees in computer science, in software engineering or in software testing and quality. Some courses include specific modules on testing, automation, and associated tools.

This level of training makes it possible to understand the entire life cycle of a software, and to intervene in both manual and automated tests, in complex environments.

Alternative routes are possible

There are also vocational training Or reconversions via shorter or work-study courses, especially for profiles already familiar with development or IT. Some schools or organizations offer specific programs around software quality, with modules on automation, test tools and agile methodologies.

Companies appreciate these profiles when they are motivated, rigorous and able to continuously train on the tools and methods of the job.

Software testing certifications

Some professional certifications are also possible to strengthen your skills or to stand out on the job market, in particular:

• ISTQB (International Software Testing Qualifications Board) : the most recognized certification internationally.
• TMap (Test Management Approach) : more focused on test management.
• Certifications related to automation tools (Selenium, Cypress, etc.) or DevOps practices.

IV - What is the salary of a software test engineer?

The salary of a software test engineer varies according to several criteria: his level of experience, his location, his field of activity, as well as the complexity of the projects on which he works. It is a job under pressure on the market, especially with the rise of test automation and agile methods.

Early-career salary

Many factors come into play (missions, sector, scope, scope, size of the company, location, atypical skills, etc.). To give an idea of remuneration, here are forks from Apec according to the following parameters: Software test engineer F/H, Bac+5 (engineering school), consulting firm with 599 to 999 employees, Île-de-France.

• Junior (< 4 years of experience) : 3.7 to 4.5 million euros gross/year
• Confirmed (6—8 years old) : 38.5 to 49.3 million euros gross/year
• Senior (9—16 years) : 42.4 to 54.8 million euros gross/year

For a more accurate estimate, adapted to your profile and our projects, we invite you to consult our job offers.

Evolution with experience

With 3 to 5 years of experience, the salary of a software test engineer can reach a range of €42,000 to €50,000 gross per year, especially if he develops skills in automation or in managing complex test campaigns.

Senior profiles, who are called upon to supervise a team of testers or to act as technical referents, can perceive up to €55,000 to €60,000, or even more so in certain industrial or critical contexts.
