• Design and develop robust, vendor-agnostic data platforms supporting AI and machine learning workloads, with a strong focus on performance, flexibility, and multi-cloud optimisation. 

• Build structured MLOps pipelines to automate and streamline the complete model lifecycle, from development and testing to deployment and serving. 

• Design security architectures that protect infrastructure and applications while aligning with risk management strategies, data protection requirements, and security standards. 

• Continuously assess, monitor, and optimise system performance and scalability using advanced metrics, benchmarking, and predictive analytics. 

• Collaborate with AI developers, business analysts, IT operations teams, and other stakeholders to ensure technical architecture supports business objectives and operational needs. 

• Establish and maintain CI/CD pipelines, infrastructure-as-code, and configuration management practices to support rapid, reliable application deployment. 

• Ensure seamless system integration and cross-platform compatibility through API design, interoperability testing, and continuous improvement practices. 

Specific expertise and technologies   

• Strong expertise in containerisation and orchestration technologies, including Docker and Kubernetes, for scalable application deployment. 

• Experience in network architecture design, particularly in distributed systems and hybrid cloud environments. 

• Comprehensive experience with relational and non-relational databases, including Oracle, PostgreSQL, OpenSearch, and MongoDB, with a focus on high-volume transaction processing. 

• Proficiency with monitoring and observability tools such as Prometheus and Grafana for infrastructure monitoring, performance analysis, and real-time alerting. 

• Experience with advanced load balancing solutions and caching technologies such as Redis to support high-traffic applications. 

• Knowledge of security and vulnerability scanning tools, including OWASP and SonarQube, as well as secure coding, encryption, and identity management practices. 

• Strong knowledge of version control systems and CI/CD platforms, including Git, Jenkins, and GitLab CI. 

• Experience with distributed streaming and message queue technologies such as Kafka and RabbitMQ. 

• Proficiency with infrastructure-as-code tools such as Terraform and AWS CloudFormation. 

• Familiarity with configuration management tools such as Ansible for system administration and automation. 

• Familiarity with AI-powered code assistants such as Amazon Kiro and GitHub Copilot would be considered an asset. 

• Good knowledge of the European Commission grant management ecosystem, including eGrants, would be considered an asset. 

Education 

• EQF Level 6 or higher in a relevant field such as Computer Science, Information Technology, Systems Engineering, or a related discipline. 

Skills and competencies 

• Strong analytical, problem-solving, and troubleshooting skills. 

• Excellent organisational and time-management skills, with the ability to manage priorities in a dynamic technical environment. 

• Strong team spirit and proven ability to work effectively in cross-functional teams. 

• Ability to integrate quickly into an international and multicultural working environment. 

• Excellent communication skills, including the ability to explain complex technical concepts to both technical and non-technical stakeholders. 

• High attention to detail, particularly in infrastructure design, documentation, and operational follow-up.
