Bank Julius Bär & Co. AG

Senior System Architect ML & AI

📍 Zurich

Role and responsibilities

You design and are responsible for the Solution Architecture of applications and AI platform components in delivery. You ensure that Solution Architectures in delivery adhere to architecture standards and are aligned with the target architectures of the domain. You initiate architecture decisions, document them as Architecture Decision Records (ADR) and have them approved by the relevant architecture boards. You advise and coach software engineers on the implementation of Solution Architectures and ensure technical feasibility. Within the ML & AI ART in collaboration with the Lead Architect, you apply and refine the ART‑level target architecture within team and initiative contexts. You drive hands‑on architectural design for AI and ML solutions within the teams, balancing consistency while addressing delivery needs. You support the delivery of key ART initiatives (e.g. the AI automation orchestration layer) by translating high‑level architecture into concrete solution designs. You ensure alignment and integration with enterprise platforms, data capabilities, security standards, and MLOps services. You identify architectural risks, dependencies, and technical debt at team and solution level, and escalate them proactively. You contribute architectural input to PI Planning, backlog refinement, and roadmap discussions from a delivery and feasibility perspective. You act as the primary architectural contact for assigned teams, while aligning closely with the Lead Architect and other System Architects.
