Family group born in northern France in 1853, now a multi-national and a multicultural company, Lesaffre is committed to working with confidence to better nourish and protect the planet. In close collaboration with its clients and partners, Lesaffre employs 11 700 people in more than 50 countries. Lesaffre achieves a turnover of 3,2 billion euros. At Lesaffre, Digital, Data & Tech (DDTech) is a fundamental transformative force for Lesaffre growth. It is a lever to increase customer centricity and user experience, achieve operational excellence, supercharge R&D, and empower our teams across the entire company. This transformation runs on a growing multi-cloud infrastructure (AWS, Azure), a SAP ecosystem in production, engineering squads that ship continuously, and a portfolio of managed service partners. The stability of the Run, the control of costs, and the reliability of our partners are daily, concrete stakes that can no longer rest on informal or fragmented practices. Support of the information system is delivered by several autonomous teams (Support, SAP, Infrastructure, Platform), each on its own scope. For the whole to work coherently, we need a central role able to coordinate these teams, steer the overall quality of the Run, and raise the alarm when something drifts. In this context, Lesaffre is recruiting an IT Operations & Reliability Manager. This is a cross-functional role at the center of a federated operating model. You do not run the support of every system yourself; you set the standards, operate within your own scope, and make sure the autonomous teams work as one: consistent escalation paths, clean hand-offs, and disciplined arbitration of cross-team priorities. Your authority comes from the quality of your analysis, the clarity of your processes, and your ability to align autonomous teams toward a common objective, not from hierarchical reporting lines. Key Responsibilities:  Run Management & System Stability • Steer the Run: Drive the overall quality of the Run across the information system: track availability, performance, and reliability indicators of the services in production (major applications such as SAP, AWS Cloud environments, etc.). • Observability: Deploy and run the Group observability chain (OpenTelemetry, Grafana, system monitoring tools): collect, correlate, and make legible the signals from every team, for both engineering teams and management (KPIs to be established). • Crisis Command: Take the lead during major cross-team operational incidents; delegate technical coordination to the Group Infrastructure lead when the incident is localized on that scope. • Cross-Team Coordination: Coordinate the Support, SAP, Infrastructure, and Platform teams on hand-offs, escalations, and arbitration of cross-team priorities. • Post-Incident Learning: Run post-incident analyses together with the teams involved and follow the corrective action plans through to closure. • Continuous Improvement: Drive a continuous improvement approach to the Run together with the teams concerned: identify priority areas, build the action plan, and follow it through to closure. • Executive Reporting: Produce a quarterly Run health report: major incidents, SLA adherence, trends, costs, and corrective actions in progress. • Technical Committees: Take part in the various technical committees with the teams in charge and the associated service providers. • Maintenance Planning: Contribute to the planning of major maintenance operations involving several teams. • Subsidiaries & Regions: Coordinate maintenance activities with the subsidiaries and regions. Resilience & Operational Continuity • Operational Resilience: Build and maintain a clear view of how critical technology can keep operating under major disruptions (data center outage, regional cloud failure, loss of connectivity or supply). • Geopolitical & Sovereignty Risk: Anticipate scenarios where access to key technologies or providers could be constrained (geopolitical restrictions, politically blocked access to AI models or SaaS) and define credible fallback options. • Continuity Planning: Work with the Infrastructure, SAP, and Platform teams to ensure disaster recovery and business continuity plans are defined, tested, and kept current. • Robustness by Design: Promote architectural and operational choices that reduce single points of failure and critical vendor lock-in. ITSM Governance • Common Processes: Propose and align common ITSM processes (Incident, Problem, Change) across all teams: set a frame of operational stability while preserving the agility of the delivery teams. • Escalation Rules: Contribute to establishing, with each team, the cross-team escalation rules: who receives what, within what time, at what priority level. • Standards & Tooling: Run and operate the ITSM standards (Jira Service Management) for your own team: workflows, categorizations, SLAs, reporting. Contribute to their adoption by the other teams. • Service SLAs: Contribute to defining the service SLAs between Engineering & Infrastructure and its internal customers: local IT, Business Units, and business functions. FinOps & Cost Control • Consumption Steering: Ensure the monitoring, analysis, and steering of Cloud consumption (AWS, Azure, Snowflake) and of hosting partners (OXYA and others), in coordination with the teams concerned. • Budget Alerts: Configure budget drift alerts and escalate any overrun to the Head of Engineering. • Optimization Policy: Drive and ensure the implementation of a Cloud cost optimization policy: build the action plan, coordinate its rollout with the teams, and measure the gains. • Licensing: Manage software licenses: optimization, renewals, and control of usage compliance. • Tagging Policy: Define and drive the adopt
