Why Join Keyrus Today?

Keyrus is an international group of 2,800 consultants and experts present in 28 countries, driven by a strong belief: it's not artificial intelligence that transforms companies, but intelligence designed, structured, and integrated into their operations.

For over 30 years, we have been building the data foundations that enable intelligent systems to create value. We design the operating system of the intelligent enterprise, where data, AI, and human expertise integrate at the heart of business processes to generate sustainable performance. At Keyrus, we bring operational intelligence to life.

Artificial intelligence does not replace humans. It allows them to focus on what no system can replicate: understanding, deciding, designing, and innovating. Joining Keyrus means building your judgment, expertise, and ability to solve complex problems.

Technology is an accelerator. The Keyrus culture makes the difference. Operational excellence connects the two.

What Awaits You

• You build end-to-end production applications: frontend, backend, database, deployment.
• You integrate AI components developed with the AI Engineer into robust and maintainable applications.
• You ensure the quality of code, application architecture, and security of what is deployed, not just its feasibility in demonstration.
• You implement tests, CI/CD, and infrastructure as code for reliable and repeated deployment.
• You collaborate with the Foundations Architect on the application integration of the architectures they design.
• You develop skills in global software architecture, distributed systems, and technical governance as your seniority progresses.

What You Bring

The Architect of Intelligence Foundation: essential qualities, present in the criteria below: curiosity, creativity, communication, professional awareness, culture, ability to act.

Experience and Background

• Significant experience in developing production applications, regardless of your starting point: ESN, software publisher, startup, or final client side DSI.
• Proven practice in deploying applications at scale, from code to exploitation, not just their conception on a diagram.
• Experience collaborating with architects or data/AI teams on the integration of complex technical components.

Attitude and Mindset

• Engineering rigor that goes beyond demonstration validation: you think production, maintainability, and security from conception.
• Real autonomy over the entire application chain, from code to deployment.
• Ability to collaborate closely with the Foundations Architect and the AI Engineer, without depending on them to advance in your scope.
• Curiosity for integrating AI components into robust applications, without seeking to become an orchestrator of agents yourself.
• Ability to produce, document, and transmit what you build, so that the code lasts beyond your presence in the team.

Essential Technical Skills

• Mastery of software development fundamentals: object-oriented programming, design patterns, data structures, algorithmic complexity.
• Deep knowledge of at least one production back-end language (Java/Spring, Python, Node.js/TypeScript, or .NET/C#, depending on the client's ecosystem).
• Mastery of a production front-end framework, such as React, Angular, or Vue.
• Design of microservices architectures and application architectures capable of scaling.
• Design of event-driven architectures and distributed systems.
• Design and querying of relational databases and caching solutions.
• Design of REST or GraphQL APIs.
• Containerization and orchestration of applications with Docker and Kubernetes.
• Deployment on the cloud (AWS, GCP, or Azure) and infrastructure as code management (Terraform).
• Implementation of CI/CD pipelines and team-scale testing strategies (unitary, integration).
• Securing applications in production and implementing operational observability (logs, metrics, alerting).
• Writing technical architecture dossiers and documentation for other teams.
• Integration of language model APIs (Anthropic, OpenAI, Mistral, Google Gemini, etc.) at the application level, with agent orchestration remaining the responsibility of the AI Engineer.
• Fluent professional English, both written and spoken, essential regardless of experience level.
