SimplifyNext is home to one of the largest certified platform engineering teams in Singapore, led by veterans who have built and operated secure, enterprise-grade platforms across the region.
Our Platform Engineering practice delivers mission-critical infrastructure platforms for public sector and large enterprise clients. You will work closely with senior architects and consulting leaders who focus on reliability, scalability, and operational governance, not just routine system support.
In parallel, SimplifyNext runs a strong AI and automation practice, enabling our platform teams to support modern, containerised, and enterprise-scale workloads. If you are looking to go beyond basic system administration and work on platforms that operate in secure and regulated environments, this is your opportunity.
What You’ll Do
You will support and operate enterprise-grade infrastructure platforms hosted within a private on-premise data centre environment, taking strong ownership of platform stability and day-to-day operations. This role involves administering and maintaining Red Hat Enterprise Linux systems, managing Kubernetes clusters, and ensuring the reliability and performance of the underlying infrastructure stack.
In this role, you will perform system patching, troubleshoot operating system and container-level issues, and automate operational processes using Bash scripting. You will administer Kubernetes environments including cluster monitoring, node and workload management, storage integration, and supporting platform upgrades to maintain high availability.
You will contribute to change implementation and configuration management activities, following structured incident and change management processes. You will collaborate closely with infrastructure, network, and database teams to diagnose issues across compute, storage, and networking layers, ensuring operational consistency and uptime.
Where applicable, you may also support enterprise application platforms running on the infrastructure stack, contributing to platform-level troubleshooting and environment configuration in collaboration with senior engineers and architects.
Throughout your work, you will uphold operational standards, maintain proper documentation, and continuously improve platform stability and efficiency.
What We’re Looking For
We are looking for engineers with a strong ownership mindset who take responsibility for platform reliability and operational quality. You should be comfortable working at the infrastructure and container platform layer, thinking beyond individual servers and understanding how systems interact across environments.
This role requires solid troubleshooting capability, attention to detail, and the ability to work effectively under the guidance of senior architects. You should be comfortable balancing responsiveness with process discipline in structured environments.
Clear communication and theability to collaborate effectively with architects, infrastructure teams, and stakeholders are essential.
