The posting

Assurity Trusted Solutions is a wholly-owned subsidiary of GovTech, providing infrastructure, operational, governance, assurance, and cybersecurity services that support government and commercial organizations. Working at the intersection of technology, reliability, and security, the team helps build and operate platforms that enable critical services to run effectively and securely.

As a System Engineer dedicated to Day 2 Operations, you will focus on maintaining, optimizing, and ensuring the absolute stability of our enterprise hybrid infrastructure. This role is well suited to someone who excels at the "post-deployment" lifecycle—keeping business-critical Nutanix hyperconverged infrastructure (HCI) systems and Red Hat Enterprise Linux (RHEL) platforms secure, performant, resilient, and continuously automated.

Responsibilities

  • Day 2 Operations & Lifecycle Management: Own the monitoring, proactive health-checking, performance tuning, and capacity management of enterprise Nutanix HCI clusters (AOS/AHV) and RHEL environments.
  • Patching & Compliance: Manage routine and emergency patching, kernel upgrades, and firmware updates across Nutanix blocks and RHEL estates while adhering strictly to government security baselines and minimizing system downtime.
  • Infrastructure Automation: Write and maintain Ansible playbooks and Bash scripts to automate repetitive system administration tasks, configurations, and configuration drift management.
  • Incident & Problem Management: Serve as the technical escalation point for complex infrastructure incidents, conducting deep-dive root cause analysis (RCA) and implementing permanent fixes.
  • Backup & Disaster Recovery: Regularly manage, validate, and test disaster recovery (DR) procedures and backup replication policies across our production nodes.
  • Collaboration: Work closely with application developers, security operators, and infrastructure architects to ensure platform changes cleanly align with Day 2 operational stability.

Requirements

  • 3-5 years of hands-on experience in enterprise systems engineering, with a heavy emphasis on production infrastructure operations (Day 2 support).
  • Strong competency managing Nutanix environments, including Nutanix AHV/ESXi, Prism Central, and lifecycle management (LCM).
  • Deep expertise in Red Hat Enterprise Linux (RHEL) administration, covering storage management (LVM), performance tuning, security hardening, and OS troubleshooting.
  • Hands-on experience with Ansible for system automation, configuration management, and patching workflows.
  • Solid understanding of core enterprise infrastructure concepts: networking (VLANs, routing), storage protocols, and security principles.
  • Familiarity with enterprise monitoring pipelines (e.g., Nutanix Pulse, Prometheus/Grafana, or Syslog).
  • Nutanix Certified Professional (NCP) or Red Hat Certified System Administrator / Engineer (RHCSA / RHCE).
  • Experience operating infrastructure within a highly regulated environment or Singapore public sector context.
  • Basic exposure to container platforms like Red Hat OpenShift or vanilla Kubernetes.
  • Willingness to participate in a scheduled on-call rotation for high-severity production incident resolution.

Benefits

  • We promote a learning culture and encourage you to grow and learn with training budgets and certification sponsorships.
  • Annual Leave Benefits with additional perks such as Family Care and Birthday Leave.
  • Contract Staff enjoys the same comprehensive benefits as Permanent Employees.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
