About the company
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.
About the role
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.
