Job description

OCTO Job

Are you one of those who think that even with several years of experience, we continue to learn? So we are on the same wavelength! What if we talked about it?

Within the Software Engineer Workshop, we find communities of practice organized by tribe. The idea is to come together and share common expertise, to develop skills in human-sized teams. Your missions will therefore be to do consulting, delivery and R&D.

Being Tech Lead at OCTO means:

1. Doing consulting as well as delivery: participate in the framing, BUILD and agile development of applications in compliance with Crafts best practices with a Gen AI touch: check! And of course, who says advice, says convictions: proposing the most suitable solution also means knowing and daring to challenge our customers (and it's in our DNA!);
2. Active participation in “Software Engineer” R&D: on the program, technological monitoring & best practices. Some “hot” topics of the moment? Gen AI, Crafts, Archi, Responsible Digital;
3. Train & mentor: do you care about sharing knowledge and improving the skills of employees? We are convinced and loudly advocate the value of transmission. Mentoring and management of your career will therefore be in the spotlight. And yes, at OCTO knowledge is not a private preserve.

Qualifications

1. A base of technical know-how: Gen AI, Crafts (TDD, DDD, pair, programming, code review, etc.). You master one or more languages ​​including Java, Python, React, Angular or Vue. You are curious to explore their potential in Gen AI uses. Beyond technologies, it is your desire to learn and progress that makes the difference. You want to know more about the subjects of Responsible Digital, Eco-design, Accessibility, etc.
2. A range of interpersonal skills: a maverick spirit capable of questioning and challenging ideas, a strong appetite for teamwork and collective success.

Hybrid work policy: We practice 2/3 days of face-to-face work per week. Since teleworking is linked to the nature of each consulting mission, flexibility is necessary if the client context requires it.

Location: Our offices are based in Opéra. Our missions take place mainly in Paris and Île-de-France

Language proficiency: A minimum C1 level of French is required to intervene effectively with our clients.
