Accessible after a BAC +2, the ENSEA Engineering cycle through work-study allows students to combine the theoretical knowledge acquired in class with the practical skills developed in a company. The work-study program allows them to acquire initial long-term professional experience, which will be a real springboard for their career.
The ENSEA Engineer training through work-study programs trains operational engineers and experts of their fields:
The course combines scientific teaching from the core curriculum of the general ENSEA Engineering cycle and specialist teaching.
The program is equivalent to 60 ECTS credits per year.
The training offers two courses in the 3rd year: Integrated Digital Systems and Networks and Telecommunications.
Apprentices have a field experience, key in their occupational integrationThe know-how and interpersonal skills they acquire in business are complementary to the theoretical knowledge learned in class and give rise to highly sought-after engineering profiles.
At the end of the course, apprentices acquire the ENSEA Engineer title specializing in electronics and industrial computing, a level 7 diploma (BAC +5), multi-certified and recognized by the industry.
50% to 70% of annual time spent in the company
Employee status and monthly remuneration
Company-funded schooling
Admission based on application file
The training can be followed in initial training (apprenticeship contract) for students under 30 years of age (except for exceptions provided for by law); or in continuing education (resumption of engineering course) for employees or job seekers.

As a first-year student in ENSEA's apprenticeship program, I am completing my work-study program at Elynxo, a company specializing in the design, manufacturing, and maintenance of optronic equipment and subassemblies for the defense, security, and industrial sectors. This involves designing a calibration device for optical sensors, developing its mechanical, electronic, and software architecture, which involves researching electronic components and developing the embedded program. I am also involved in team product design, where we develop validation plans, manage tests, and propose fixes. In addition, I contribute to setting up automated test benches to ensure the quality of prototypes. What fascinates me about this job is, above all, the field itself, as well as the daily challenge of finding new solutions and solving problems. I also enjoy teamwork, which allows for increased efficiency in moving projects forward and contributing to the company's development.

Whether you come from a Bachelor's degree, a university program (BUT, BTS) or a scientific CPGE, admission is based on application review. via the IMT Learning platform followed by a motivational interview.
Please note: Applicants must be under 30 years old. After this age, it is possible to join ENSEA for continuing education (see admission requirements below).
Whether you are in a university course or in a scientific CPGE, selection is made based on file via the IMT Learning platform, followed by motivational interview by video.
Successful candidates are looking for a host company with ENSEA and the CFA Union ORSAY.
Final admission is granted within the limit of available places for any pre-selected candidate who has obtained their BAC +2 diploma (BUT, L2, L3, Bachelor) and signed their apprenticeship contract.

ENSEA has prepared 5 tips to help you prepare well and give yourself every chance of success!
Find our tips for your oral exams here!The apprentice engineer has the same status as a employee employee under a fixed-term contract, which guarantees him a monthly salary during their 3 years of training. Their rights and duties are governed by the general provisions of the Labor Code. The remuneration corresponds to a percentage of the minimum wage, adjusted according to the apprentice's age and year of training.
The assigned tasks must correspond to the development of the training. Multidisciplinary projects result in the drafting of deliverables, evaluated by the teaching team and the industrial tutor.
Accessible after a BAC+2 in science and technology, the ENSEA Engineering cycle returning to studies, allows employees or job seekers to acquire solid skills in electronic engineering and industrial computing while continuing their professional activity. The pace may include face-to-face course sessions and personal work in the company.
The ENSEA engineer training through work-study is organized according to 4 main themes:
A minimum of 9 weeks of international experience is required.
A personalized project:
Summer programs:
For apprentice engineers: 600 hours of lessons
For Continuing Education trainees: 300 hours of lessons
For apprentice engineers: 600 hours of lessons
For Continuing Education trainees: 500 hours of common courses
For apprentice engineers: 600 hours of lessons
For Continuing Education trainees: 500 hours of common courses
600 hours of individual (common) industrial project
In the first semester, the lessons are part of a common core:
In the second semester, 17 weeks are devoted to developing one of the following two options:
The main objective is to master the design methodology of digital systems. These increasingly rely on complex integrated structures and a significant part of the design is linked to the realization and use of these structures (ASIC, LCA, RISC microcontrollers). The complexity of these systems requires that testing be taken into account from the early phases of the project.
Although this option does not require in-depth knowledge of mathematics, it does require a very good ability to synthesize to be able to understand a project in its entirety and to evaluate the influence of the various design choices of the sub-functions on the entire system.
This option is located at the border of the fields of microelectronics (analog behavior of devices), microcomputing, digital technology, and IT (CAD and real-time systems); it therefore covers a very broad technological field.
The courses in the Networks and Telecommunications option should enable students to acquire mastery of the concepts and tools used in the design, implementation and operation of communications systems on the one hand and networks on the other.
The Networks section covers the analysis of the main types of protocols, the different LAN/WAN profiles, technological solutions, current operator offerings, as well as an approach to methods and tools for evaluating network performance or administering its operation. It should enable the design of network architectures and their sizing to be controlled.
The Telecommunications section covers methods of coding and transporting information from conventional systems to new generation systems. The acquired knowledge should enable the analysis of the operation of a specific system, the evaluation of its performance and the implementation of the corresponding measurement methods.
Students in the Audiovisual Systems program will also deal with applications specific to audiovisual transmissions and broadcasts (DVB, etc.).
Work-study programs are a genuine opportunity for professional development. Field experience and the inductive approach enabled by the systematic application of knowledge lead to rapid and valued skill development.
Within their host company, ENSEA apprentice engineers have activities related to electronics, industrial computing (digital systems, software engineering, etc.) and networks and telecommunications.
They become project managers with strong analytical skills, who know how to adapt to technological changes, and master the management of complex industrial projects.
They also stand out for their project management, business life and industrial market profile.
Progressing within the company also means acquiring, very early on, a large number of skills that are essential for engineering professions: communication, teamwork, agility, management, cross-functional working, etc.
The work-study program is both a professional experience that can be highlighted on your CV, but also a real taste of the world of work, its codes and its customs.
Being an apprentice means having three lives: personal, professional, and academic. It's about knowing how to juggle each activity and manage the workload. In short, a real challenge that turns us into professionals!Julien, Class of 2026
Apprentice engineers benefit from dual support from ENSEA and the CFA Union Orsay (and from the INA for those who have chosen this program) in their search for a host company. This takes the form of:
Sectors of activity:
ENSEA engineers who graduate from the work-study program work mainly in industrial sectors such as construction, transport, communications, IT services, and telecommunications.
Areas of expertise:
The class of ENSEA engineers graduating in 2024 was interviewed in January-February 2025, in accordance with the CGE (Conference of Grandes Écoles) calendar.
