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.

Must have:

• 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
• Ability to read and debug backend code (Node.js, Java, Python, .NET) to identify and resolve production issues
• Experience with monitoring and observability (Azure Monitor, Application Insights, Log Analytics or similar), using logs, metrics, and traces to investigate incidents
• Working knowledge of SQL, data analysis, and data-related issue resolution
• Practical experience with scripting/automation (Python, Bash, or PowerShell), Git, and CI/CD pipelines
• Experience using AI-assisted tools (e.g., ChatGPT, Copilot) for debugging and automation, with strong technical judgment beyond AI outputs
• Excellent communication skills, strong ownership mindset, and ability to work effectively in high-pressure production environments with technical and non-technical stakeholders

Nice to have:

• Support experience with Kubernetes or OpenShift and basic cloud networking (DNS, load balancing, firewalls)
• Familiarity with API and integration tooling (Postman, curl) and event-driven systems (queues, webhooks, messaging)
• Experience improving monitoring and alerting quality (noise reduction, SLIs/SLOs)
• Exposure to financial services or high-availability environments
• Familiarity with Jira, Confluence, and modern incident management tools

At Accesa you can:

Enjoy our holistic benefits program that covers the four pillars that we believe come together to support our wellbeing, covering social, physical, emotional wellbeing, as well as work-life fusion.

• Physical Wellbeing: Our wellbeing program includes medical benefits, gym support, and personalized fitness options for an active lifestyle, complemented by team events and the Healthy Habits Club.
• Work-Life Fusion: In very dynamic industries such as IT, the line between our professional and personal lives can quickly become blurred. Having a one-size-fits-one approach gives us the flexibility to define the work-life dynamic that works for us.
• Emotional Wellbeing: We believe that to maintain our overall health, we need to invest in our mental wellbeing just as much as we do in our physical health, social connections or in achieving work-life balance.
• Social Wellbeing: As a growing community in a hybrid environment, we want to ensure we remain connected not just by the great work we do every day but through our passions and interests.
