Context and Purpose
Within the Integrated Application Services Center (CS AIR), the Senior Architect Audit & Transformation operates within the framework of the DES program and, more broadly, in the evolution of the tax information system. The mission aims to provide independent audit and transformation expertise of the tax application portfolio. It seeks to assess the robustness, relevance, and sustainability of existing or future solutions, manage technical debt and architectural risks, and illuminate investment and transformation decisions.The Senior Architect Audit & Transformation defines realistic and controlled trajectories to sustainably improve the resilience, performance, security, maintainability, operability, and scalability of the information system. They act as a reference for management, architects, program managers, business units, technical teams, and external partners.
Main Activities
Conduct technical and architectural audits of existing solutions, those under development, or proposed by vendors.
Establish objective diagnostics regarding technical debt, critical dependencies, structural limits, performance, resilience, security, maintainability, and operability.
Evaluate the alignment of architectures with business objectives, regulatory constraints, and architectural principles.
Identify and prioritize architectural risks and their business, technical, budgetary, and operational impacts.
Define target architectures, transformation scenarios, and migration or modernization trajectories.
Conduct impact, opportunity, and risk analyses to inform governance decision-making.
Challenge choices and estimates proposed by external vendors.
Lead or contribute to architecture reviews and formalize decisions, conditions, reservations, and action plans.
Support teams in implementing recommendations and verify their effective consideration.
Measure results obtained and adapt recommendations as findings, constraints, or priorities evolve.
Contribute to the analysis of complex technical incidents when their causes may be architectural.
Clearly present options, trade-offs, risks, costs, and consequences to facilitate decisions.
Minimum Expected Experience
At least ten years of relevant experience in application architecture, including several years in audit, transformation, or architectural governance roles.
At least three significant architectural audit missions, technical debt diagnostics, or transformation of complex systems.
Proven experience in defining modernization trajectories and presenting them to decision-making bodies.
Experience in challenging vendors, evaluating solutions, and following up on recommendations.
Experience in a public, regulated environment or one with comparable complexity.
Expected Deliverables
Audit and architectural diagnostic reports, including findings, evidence, risks, and prioritized recommendations.
Maps of components, flows, dependencies, obsolescence, and risks.
Existing and target architecture files.
Compared transformation scenarios and decision support files.
Modernization roadmaps, migration trajectories, and technical debt reduction plans.
Documented architectural decisions, technical opinions, and review minutes.
Action plans with priorities, responsibilities, success conditions, and verification criteria.
SOFT SKILLS
Ability to distinguish structural issues from secondary topics and prioritize actions.
Critical thinking, independence of judgment, and ability to formulate well-founded recommendations.
Ability to model, diagram, and explain complex systems.
Ability to present options, trade-offs, risks, and costs to technical and non-technical audiences.
Ability to constructively challenge and gain buy-in around architectural decisions.
Business, solution, and results orientation.
Rigor, autonomy, method, and sense of quality.
Ability to work in a multidisciplinary environment and manage multiple requests simultaneously.
Evaluation Method
Analysis of the application file and responses to specific questions. Written test based on an audit and transformation case, followed by an interview for selected candidates. The evaluation will focus on the ability to objectify a diagnosis, prioritize risks, compare scenarios, and defend a realistic trajectory.What you'll do
