Senior Software Engineer - DevOps (ERP)

Ho Chi Minh - Viet Nam


Outsource

You drive the step-by-step migration of our ERP from a single virtual-machine setup towards containerized workloads on Linux and Docker. You design, implement, and maintain agent-based deployment for both virtual machines and - increasingly - containers, making sure they are provisioned, deployed, and updated reliably. You provision and operate virtual machines, containers, deployment targets, and delivery infrastructure in Azure. You ensure the cloud onboarding wizard (React) and the surrounding cloud services run reliably so that customers can work without interruption. You instrument the platform with telemetry, monitoring, and observability so that issues are detected early and operations stay transparent. You design, implement, and maintain CI/CD pipelines and automate build, packaging, testing, and deployment processes. You support the migration of existing build and release processes towards GitHub Actions and modern delivery workflows. You manage and evolve self-hosted runners and build infrastructure. You collaborate with Quality Engineering to integrate automated tests into delivery pipelines. You work with Release Management to improve release reliability, transparency, and automation. You identify bottlenecks in the software delivery process and continuously improve developer productivity. You help establish the technical foundation for future Continuous Delivery and Continuous Deployment scenarios#OPERATIONS & ON-CALL RESPONSIBILITYTogether with your future colleague and the wider team, you take shared responsibility for keeping the platform running for our customers. We ensure disruption-free operations primarily through the right tooling and welldefined processes - automation, telemetry, and clear escalation paths - not through manual firefighting. This is explicitly not about working fixed shifts: it is about ownership and reachability, being there within a defined reaction time when problems occur, including on weekends. You take ownership of the reliable operation of our machines and - increasingly - containers, so that customers can keep working. You build the tools and processes that keep operations running smoothly and prevent incidents before they happen. You make sure that deployments and the cloud wizard (React) keep functioning correctly in production. You share responsibility for operational availability in a rotation with the team - the goal is to respond within a defined reaction time when incidents arise, not to staff fixed shifts. You help build the alerting, telemetry, and on-call processes that make fast and reliable incident response possible.
