Responsibilities:

• Develop and maintain the target architecture for generative AI, machine learning, and agentic AI.


• Establish reference architectures and decision patterns for on-premises, cloud, and hybrid deployments, tailored to sensitivity, integration needs, and operational requirements.


• Define architectural frameworks for AI Gateway, Model Context Protocol, retrieval, model access, agents, identity, logging, observability, and lifecycle management.


• Guide delivery teams in architectural choices, trade-offs, and the transition from sandbox or PoC to production in collaboration with technology architects.


• Conduct architecture reviews and timely highlight deviations, technical debt, dependencies, and risks.


• Integrate privacy, least privilege, data minimization, isolation, and traceability by design in collaboration with security and data functions.


• Identify and prioritize reusable platform and integration building blocks with the AI Enabling Team and the Internal Developer Platform.


• Translate technological evolutions into concrete impacts, options, and decision points for the client.

Technical Competencies:

• Extensive experience in solution architecture or IT architecture in enterprise environments.


• Experience with APIs, event, and integration patterns.


• Understanding of LLM and AI platform architectures, retrieval, model serving, agents, evaluation, and observability.


• Ability to translate regulations and security requirements into practical architectural principles and guardrails.


• Experience with architectural decision records, reference architectures, non-functional requirements, and lifecycle management.


• Knowledge of the public sector, G-Cloud, or OISZ context is a plus.

Generic Competencies:

• Innovation: You keep up with the latest trends and experiment with innovative AI technologies.


• Problem-solving: You analyze complex issues and translate them into pragmatic solutions.


• Collaboration: You work smoothly with colleagues from various disciplines (IT, business, security, architecture).


• Communication: You can clearly explain technical concepts to both technical and non-technical stakeholders.


• Advising: You excel in structuring, visualizing, advising, and facilitating multidisciplinary decision-making.


• Result-oriented: You monitor deadlines and ensure quality deliverables.
