Senior Infrastructure Engineer

As a Senior Infrastructure Engineer, you build and maintain the SaaS Tooling that powers provisioning, management, and configuration for TOPdesk's entire SaaS platform. Whenever a customer environment is created, moved, upgraded, backed-up/restored, managed, or purged, it runs through tools your team owns: the Execution Server, SaaS Tooling Bridge, Control Panel, and related services. You will help your team bring the tooling system to the next level and make sure that it serves the company’s technical vision. 

You prefer fixing root causes over repeating manual tasks, and you're comfortable in codebases mid-transition, where old and new systems coexist. You write code others can pick up easily, and you weigh the impact on other teams before changing shared tooling. You operate agents yourself and bring our AI-native ways of working into how your components gets built, changed, and remediated. 

What this is not: A pure cloud-architecture role, or a ticket-driven ops seat kept away from the code. You own the automation that provisions and operates every customer environment, and you're close enough to the systems to redesign them, not just patch around them. 

• Build and maintain responsive, scalable systems for managing customer environments. 

• Orchestrate containerized workloads with Kubernetes, owning the deployment and orchestration layer end to end, not just the application code that calls it. 

• Build and maintain the scheduling system for deploying and managing SaaS single- and multi-tenant components, databases, and networking across 12 global datacenters. 

• Own architecture, performance, and scaling of SaaS Tooling; extend the bridge between SaaS Tooling and internal platforms to automate operational requests (license changes, feature flag rollouts, environment actions) with clear fallback procedures. 

• Identify manual, repetitive operational tasks in TOPdesk deployment and engineer automation or self-service solutions. 

• Improve the reliability of critical-path tooling: fix bugs, add tests, and strengthen observability to catch failures early. 

• Work closely with Hosting, SRE, DevEx, and Observability teams, and product teams, to support feature delivery and operational needs. 

• Participate in L2/L3 support, including weekday, weekend, and occasional night on-call rotations, troubleshooting product operations, security operations, and urgent engineering issues. 

• Build and maintain a Virtual Appliance build system for on-premises delivery. 

• Bring AI-native ways of working, agents, subagents, and shared patterns, into how the team builds and operates tooling.
