Singapore ELLIOTT MOSS CONSULTING PTE. LTD. Full time $90,000 - $120,000 per year

Job Description

We're looking for an Application Operations Engineer to take ownership of one or two enterprise applications, covering day-to-day operations, patching, reliability, and production support. You'll collaborate with build/architecture teams, strengthen our DevSecOps practices, and help maintain secure, scalable online services.

Key Responsibilities

  • Own operational health for assigned applications (availability, patching, monitoring, incident response, RCA).
  • Set up and manage application platforms in production (e.g., WebSphere in HA), including post-setup patching and tuning.
  • Participate in architecture/design sessions to define integration points (e.g., Web Services, MQ, SFTP) and operational requirements.
  • Provision and manage containerized services; apply image/repository lifecycle concepts and deploy container-centric workloads.
  • Maintain enterprise web and microservices architectures (capacity, scaling, resiliency, observability).
  • Implement and improve DevSecOps tooling and automation across CI/CD and security controls.
  • Define, document, and improve operational processes (runbooks, SLAs/SLOs, change/incident/problem management).
  • Perform OS-level and application-level patching, operational housekeeping, archival, backup, and recovery.
  • Apply hardening, scanning, and security posture best practices in line with governance requirements.

Must-Have Skills & Experience

  • STEM background (e.g., computing, engineering, information systems) or equivalent practical experience.
  • Hands-on administration and setup of applications on RHEL and Windows environments.
  • Experience maintaining enterprise-scale online web architectures and microservices (production operations, HA/DR, patching).
Good-to-Have (Optional)
  • Familiarity with Agile practices and tooling to support the delivery lifecycle.
  • Understanding of end-to-end web application flow (SSO, web server, app server, database, and supporting components).
  • DevSecOps tooling background (e.g., GitHub/GitLab, Bamboo, SonarQube, security scanning) with ability to integrate toolchains.
  • Container ecosystem know-how (images, registries, deployment) and command-line/scripting skills (Shell, PowerShell).
  • Experience with middleware/integration (MQ, SFTP) and application servers (e.g., WebSphere in HA).
