The world is how we shape it*

Integrated into a project team composed of architects, developers, business analysts, and business experts, you will act as a Technical Lead and support the team in implementing innovative solutions that meet our clients' challenges.

In a context where Artificial Intelligence is permanently transforming software engineering practices, you will contribute to the realization of build projects, modernization of legacy applications, and evolutionary maintenance by leveraging an AI-Driven approach.

As such:

• You will participate in the definition and implementation of technical architectures in collaboration with architects and project teams;
• You will develop and industrialize the most complex functionalities, ensuring their performance, maintainability, and scalability;
• You will support developers in their technical choices and act as a technical mentor within the team;

• You will perform code reviews, disseminate Software Craftsmanship best practices, and contribute to the continuous improvement of development quality;

• You will structure projects around the principles of Specification Driven Development (SDD) to enable AI agents to intervene effectively in design, development, testing, and documentation activities, while ensuring the quality and consistency of deliverables;

• You will coordinate and orchestrate an ecosystem of AI agents involved in the entire software development lifecycle, critically evaluating their outputs to maximize the quality, consistency, and value brought to projects;

• You will contribute to improving the team's AI-Driven harness and framework by identifying new uses, optimizing existing processes, and sharing feedback;

• You will participate in the modernization of existing applications: analysis of the application portfolio, functional and technical understanding, reduction of technical debt, and definition of transformation roadmaps;
• You will be a key player in project industrialization through DevOps practices, continuous integration, and automation;
• You will participate in the analysis and resolution of complex incidents, as well as in improving application reliability.

You will work in an AI-Driven software engineering environment combining technologies such as Java, Spring Boot, Angular, and Kubernetes, where AI agents are integrated at the core of application design, development, and maintenance processes.

A graduate of an engineering school or equivalent, you have at least 5 years of experience in software development and have previously held a technical lead role within a development team.

You possess a strong culture of technical excellence acquired around Java, Spring Boot, and Angular technologies. Committed to the principles of Software Craftsmanship, you design robust, maintainable, and scalable solutions by relying on Clean Code, hexagonal architectures, automated tests, and software design best practices.

Convinced that Artificial Intelligence is redefining software engineering practices, you wish to play a leading role in the adoption and continuous improvement of AI-Driven approaches, by combining innovation, technical excellence, and control over deliverable quality, as well as adherence to the principles of responsible and controlled AI.

You are particularly comfortable with:

• Understanding complex systems and proposing pragmatic solutions;
• Supporting and advancing developers through your ability to share knowledge and mentor;
• Taking a high-level view of technical issues to identify levers for improvement and industrialization;
• Working in close collaboration with technical and functional stakeholders;
• Contributing to the continuous improvement of engineering methods, tools, and practices.

Curious, autonomous, and with an excellent team spirit, you enjoy tackling challenges that combine innovation, technical excellence, and transformation of development methods.

• A teleworking agreement to work remotely up to 2 days per week depending on your assignments.
• An attractive benefits package: health insurance, employee representative committee (CSE), meal vouchers, profit-sharing agreement, vacation and referral bonuses.
• Multiple career opportunities: over 30 job families, as many bridges to imagine together.
• Several hundred training courses accessible autonomously with Sopra Steria Academy.
• The possibility to get involved with our foundation or our partner "Vendredi".
• The opportunity to join the Tech'Me UP collective (training, conferences, watch, and much more...).
