Job description

We are seeking a Cloud Infrastructure Engineer to support the day-to-day operations and continuous improvement of our cloud and infrastructure platforms. The successful candidate will help ensure the reliability, availability, and security of cloud and on-premises environments through effective monitoring, operational support, automation, and adherence to established technology standards.

The role requires hands-on experience with core infrastructure technologies, including Windows and Linux servers, enterprise networking, storage platforms, and database technologies. Familiarity with AWS cloud services across IaaS, PaaS, and SaaS models, together with a good understanding of cloud security, operational best practices, and infrastructure resilience, will be advantageous. Experience supporting regulated environments or financial institutions is an added advantage.

The successful candidate will also contribute to technical documentation, operational procedures, project implementation, and knowledge-sharing activities while working closely with internal teams and technology partners to support business and operational objectives.

KEY RESPONSIBILITIES

• Support the operation and maintenance of cloud and infrastructure services, with a primary focus on AWS environments, including core services such as compute, storage, networking, and database platforms, alongside hybrid on-premises integration.
• Operate and troubleshoot cloud workloads across AWS and other hyperscale platforms (e.g. Azure, GCP, Alibaba Cloud) with emphasis on availability, performance, and stability of production systems.
• Support implementation of monitoring and observability solutions in AWS environments using tools such as Amazon CloudWatch, Prometheus, Grafana, and Datadog to ensure operational visibility and proactive issue detection.
• Assist in implementing and validating backup and recovery mechanisms within AWS (e.g. AWS Backup, snapshot strategies), including periodic restore testing and retention compliance.
• Support disaster recovery and high availability configurations on AWS (e.g. Multi-AZ, Multi-Region setups, load balancing) to meet business continuity requirements.
• Develop and maintain Infrastructure as Code (IaC) using Terraform and AWS CloudFormation to support standardized and repeatable cloud resource provisioning.
• Participate in 24x7 production support and incident response for AWS-based workloads, ensuring timely resolution in line with operational SLAs.
• Support implementation of cloud security, governance, and compliance controls within AWS environments, aligned with internal policies and regulatory requirements.
• Maintain operational documentation including runbooks, architecture notes, and incident post-mortems to support knowledge retention and operational readiness.
• Contribute to cloud optimization initiatives within AWS, including auto-scaling, cost efficiency, load balancing, and performance tuning under guidance from senior engineers.
• Demonstrate working knowledge of AWS cloud architecture principles and service models (IaaS, PaaS, SaaS), supporting secure and scalable cloud operations in production environments.

WHAT DOES IT TAKE TO BE SUCCESSFUL

Qualifications

• Bachelor's Degree, Postgraduate Diploma, Professional Qualification, or equivalent experience in Computer Science, Software Engineering, Information Technology, or a related discipline.
• Relevant cloud certifications (e.g., AWS Certified SysOps Administrator, AWS Certified Solutions Architect, Alibaba Cloud Certified Associate, or equivalent) will be an added advantage.
• Professional certifications in infrastructure and platform technologies, including backup and disaster recovery solutions, Windows Server, Linux, virtualization, networking, or other relevant technologies, will be an added advantage.

Work Experience

• 6+ years of experience in infrastructure operations across data centers and cloud environments.
• 6+ years of experience in cloud engineering and operations, with a strong focus on cloud environments.
• Experience working in the financial industry is a plus.
• Strong understanding of infrastructure and network operations across both data centre and cloud environments, including Windows and Linux systems, directory services (LDAP), DNS, DHCP, CDN, load balancing, clustering, email gateways, IPVPN, SFTP, and related enterprise services, with experience supporting 24x7 production operations.
• Hands-on experience in cloud operations, including provisioning, monitoring, and support of cloud workloads, with exposure to key AWS services and operational best practices.
• Experience supporting cloud backup and disaster recovery (DR) processes, including backup validation, restore testing, snapshot management, and support for high availability (HA) configurations in AWS environments.
• Solid operational and analytical skills with the ability to participate in technical decision-making, troubleshoot complex infrastructure issues, and maintain accurate and well-structured technical documentation.
• Experience using project tracking and workflow management tools such as Jira, Azure DevOps (VSTS), Trello, or equivalent platforms to support operational and project delivery activities.
