Azure DevOps Engineer

Що робити

Performance and stability work: Identify and resolve issues currently degrading the platform — missing or wrong SQL indexes on hot tables, N+1 Cosmos queries, EF Core query plans that fall off the optimiser, queue back-pressure, retry storms.
Incident response: Act as the escalation point for the product support and dev team. Diagnose and fix issues spanning bookings, widgets, payments (Mollie / Bancontact / iDEAL), webhooks, SignalR notifications, Cosmos DB content, and SQL Server data.
Production stewardship: Plan and execute releases to production, typically out of customer hours (releases usually go out late evening or around 2 a.m. CET to minimise blast radius). Own rollback strategies and smoke tests.
Platform upgrade: Plan and execute upgrades to .NET, key NuGet packages (including private feeds), Azure services, and third-party integrations — without disrupting production.
Targeted feature development: Pick up scoped backend features and changes and ship them safely.

Deep Azure production ownership — ideally 8+ years where both the application layer and the cloud infrastructure are your domain. Azure is not a deployment target here — it’s part of the system you own.
Strong DBA instincts. You can read an execution plan, recognise when EF Core is generating something the optimiser can’t use, and design indexes that match access patterns.
Azure platform depth. Hands-on production experience with App Service / AKS, Azure SQL, Cosmos DB, Service Bus, Application Insights, and Key Vault. You know how to right-size resources, contain costs, and respond to platform-level incidents — not just application-level ones.
Production maturity. Comfortable owning overnight releases, rollback plans, and the weight of a system where mistakes affect real restaurants in the morning service.
Diagnostic mindset. At home in Application Insights, SQL DMVs, Cosmos metrics, and logs. Able to find root causes in a codebase you didn’t write, with significant historical complexity.

Experience with restaurant tech, reservation systems, or any high-concurrency consumer-facing platform with payment flows.
