Senior Application Support Engineer with German

About the Project

You will join one of our ongoing projects for a leading European financial services provider, contributing to a modern, cloud-native SaaS platform built on the Microsoft Azure ecosystem.

You will be part of a dedicated team responsible for ensuring the stability, reliability, and performance of a production-critical application. The team covers end-to-end support activities, working closely with engineering, product, and customer-facing teams.

This role goes beyond traditional ticket handling meaning that you will actively contribute to incident resolution, system reliability improvements, and the overall quality of the production environment.

Responsibilities

• Production Stability: Ensure the continuous availability and reliability of mission-critical applications by owning production incidents end-to-end and keeping stakeholders informed with clear, timely communication.
• Root Cause Mastery: Diagnose complex issues across distributed systems using logs, metrics, and traces, driving permanent fixes across application, infrastructure, and data layers instead of temporary workarounds.
• Azure Cloud Resilience: Support and troubleshoot Azure environments (App Services, AKS, Functions, Storage) while working with Infrastructure as Code (Terraform, Bicep, ARM) to ensure consistent and stable deployments.
• System Visibility: Strengthen observability using Azure Monitor, Application Insights, and Log Analytics, improving alert quality and contributing to meaningful SLIs, SLOs, and reliability metrics.
• API Reliability: Safeguard integrations by debugging REST and GraphQL APIs, authentication flows, webhooks, queues, and third-party services using tools like Postman, curl, and logs.
• Data Confidence: Investigate data-related issues using SQL and backend code analysis to resolve inconsistencies, support corrections, and protect system integrity.
• Operational Efficiency: Reduce incident frequency by automating repetitive tasks with Python, Bash, or PowerShell and continuously improving internal tools and operational processes.
• Continuous Improvement: Proactively identify stability risks and optimize systems by refining runbooks, internal tooling, and support workflows.
• Shared Expertise: Scale team effectiveness by maintaining clear documentation, contributing to knowledge bases, and supporting onboarding and mentoring.

Requirements

• 3–5 years of experience supporting production SaaS or cloud applications, with strong troubleshooting across distributed systems (application, infrastructure, data), including incident handling, RCA, and postmortems
• Proficiency in German (B2/C1) and English, both written and spoken
• Strong understanding of cloud architectures and hands-on experience with Microsoft Azure (App Services, AKS, Functions, Storage), including Infrastructure as Code concepts (Terraform, Bicep, ARM) for troubleshooting
• Solid knowledge of APIs (REST/GraphQL), HTTP fundamentals, authentication flows, and practical API troubleshooting
