Take on a new challenge and apply your DevOps and CI/CD expertise in a new cutting-edge field. You’ll work alongside collaborative and innovative teammates.

You'll play a key role in designing and optimizing scalable DevOps architectures and CI/CD pipelines, ensuring seamless integration and delivery of software applications. Day-to-day, you’ll work closely with teams across the business (development, QA, operations), evaluate and recommend tools and technologies, and lead the implementation of Infrastructure as Code (IaC) practices, and much more.

You’ll specifically take care of fostering a culture of collaboration and efficiency across teams, but also ensuring the scalability, reliability, and security of cloud-based infrastructures.

We’ll look to you for:

Contribute to the elaboration of product/system specification & architecture, in collaboration with cross-functional teams
Define the software requirements specifications
- Define the functional requirements, operational requirements, interfaces requirements and the requirements linked to performance, safety, cybersecurity, Reliability Availability and Maintainability (RAM)… constraints
- Ensure that all the requirements can be verified (testability, …)
- Ensure the traceability of the software requirements through the development cycle
Define the software architecture
- Elaborate the functional and structural breakdown into software components
- Allocate the requirements to the software components
- Define the interfaces between the software components
- Define the dynamical behavior of the software
- Validate the feasibility of the solution: model simulation, mock-up
Take main technical choices for software development
- Select development tools, methodology (ex: UML, …), programming languages, coding strategy and coding rules…, strictly following internal process/methods & tools recommendations
- Contribute to the selection of the execution environment (processor, operating system, middleware, basic software…), together with the product architect, system engineering manager and hardware architect
Designing and implementing DevOps strategies:
This includes creating scalable frameworks (GitLab CI/CD components), integrating tools (compilation, SCA, SATS, etc) and processes, and aligning DevOps practices with business objectives.

Building and maintaining CI/CD pipelines:
Automating the build with powershell, python; automatic deployment processes to enable rapid and reliable software releases.
Managing cloud-based infrastructure: Overseeing the deployment and management of cloud infrastructure using tools like Terraform and Kubernetes.

- Collaborating with other teams: Working with development, operations, and security teams to ensure smooth and secure software delivery.
  Monitoring and optimizing system performance: Ensuring the system is running efficiently, is scalable, and is secure.
- Guiding and mentoring junior engineers: Helping to foster a culture of continuous improvement.
  Implementing Infrastructure as Code (IaC): Defining and managing infrastructure using code to bring agility and consistency.
- Ensuring security: Implementing security measures, identity management, and compliance controls.
- Arbitrate and validate major software design choices
- Mentor developers and provide technical leadership within the team
- Perform software/software integration, together with the software designers
- Perform hardware/software integration, together with the hardware architect
- Specify, design, prepare and perform tests and verifications of his/her deliverables
- Sustain the software
- Keep informed of the evolution of technologies through techno watch
- Contribute to standardization by reusing existing solutions or by defining reusable solutions, including COTS*
- Apply and ensure application of processes and standards
- Contribute to continuous improvement (RoE: Return of Experience, process…)
Key Responsibilities
- Design and implement CI/CD pipelines using GitLab for automated build, test, and deployment.
- Architect and manage containerized environments using Docker and Kubernetes .
- Implement GitOps workflows using ArgoCD for continuous delivery.
- Develop and maintain Infrastructure as Code (IaC) using Terraform and Ansible .
- Set up monitoring and observability solutions using Prometheus and Grafana .
- Ensure high availability, scalability, and security of cloud-native applications.
- Collaborate with development, QA, and operations teams to streamline delivery processes.
- Drive best practices for DevOps, automation, and cloud infrastructure.
Required Skills & Qualifications
- Strong experience with GitLab CI/CD pipelines.
- Expertise in Docker and Kubernetes orchestration.
- Hands-on experience with ArgoCD for GitOps deployments.
- Proficiency in Terraform and Ansible for IaC and configuration management.
- Solid understanding of Prometheus and Grafana for monitoring and alerting.
- Knowledge of cloud platforms (AWS, Azure, or GCP).
- Strong scripting skills (Bash, Python, or similar).
- Excellent problem-solving and communication skills.
Staying current with industry trends in DevOps, CI/CD, and automation practices
