Job description
At Amaris Consulting, we are looking for a Microsoft-oriented Application Engineer to take full technical ownership of MARS, our business-critical transactional application based on Cegid.
This is not a generic DevOps or Linux infrastructure role. We need someone who thrives at the intersection of application management, database expertise and cloud migration on a Microsoft stack.
You will ensure high availability, performance and resilience of the platform, while leading its transition and optimization to Azure Cloud using DevOps automation.
Your responsibilities
Run & Operations – Application Ownership
Administer and operate the MARS application running on Microsoft IIS
Ensure 24/7 availability, performance and stability of the platform

Manage and optimize Microsoft SQL Server databases:
Performance tuning, indexing, query optimization
High Availability and Clustering (AlwaysOn, failover, etc.)
Handle incidents end-to-end: troubleshooting across IIS, SQL Server, OS and network layers; root cause analysis and permanent fixes
Projects & Evolution – Cloud & DevOps
Design and execute the migration/optimization of MARS to Azure:
Setup of Azure services (IaaS/PaaS, networking, storage, monitoring)
Definition of resilience and disaster recovery strategy

Implement DevOps practices for the MARS ecosystem:
CI/CD pipelines for application and database changes (Azure DevOps, GitLab, etc.)
Infrastructure as Code (ARM/Bicep/Terraform)
Automated deployment, rollback and configuration management
Coordinate with Cegid and internal stakeholders for upgrades, patches and new releases
Collaboration & Governance
Work closely with internal IT and Infrastructure teams
Act as technical point of contact for MARS towards business, infra and vendor teams
Maintain clear documentation: architecture diagrams, runbooks, operational procedures
Your profile
Core Technical Skills (must-have)
✅ Strong hands-on experience with Microsoft IIS (hosting, SSL, authentication, load balancing, troubleshooting)
✅ Solid expertise in Microsoft SQL Server: advanced SQL, stored procedures, performance tuning, AlwaysOn / failover clusters
✅ Good knowledge of Azure with real production experience (not only training): networking, security, monitoring, cost management
✅ Strong understanding of Web Services (REST/SOAP) and integration patterns
✅ Experience with DevOps automation: CI/CD tools, scripting (PowerShell, Bash, Python)
Application / ERP Orientation
Experience managing business-critical transactional applications (ERP, core banking, billing, retail)
Experience with Cegid or similar ERP/financial/retail solutions is a strong plus
Comfortable working at the intersection of application, database and infrastructure
Soft Skills
Strong ownership and accountability mindset
Clear communication with non-technical stakeholders (business, finance, operations)
Proactive, structured and able to challenge and improve existing setups
Good level of English (written and spoken)
