System Engineer II at Capitec Bank

About the role

• We are looking for a dedicated System Engineer with strong Level 2 systems engineering experience to support our Card Processing and Transaction Switching environment. The role requires hands-on experience supporting high-availability production systems, with strong troubleshooting, monitoring, operational support, automation, and implementation skills. Since this role sits within a critical payments environment, card processing, payments, or transaction switching knowledge is a must-have. AWS or cloud platform knowledge would be beneficial, as the team will support future platform modernisation initiatives, including potential movement of components such as Postilion onto AWS infrastructure, as well as the introduction of Kafka-based messaging and event streaming capabilities. The successful candidate should be technically capable, operationally disciplined, comfortable working in a regulated banking environment, and able to take ownership of system stability, incident investigation, change support, documentation, and continuous improvement

What you’ll be doing

• Support and maintain card processing and transaction switching systems
• Investigate and resolve production incidents in a high-availability environment
• Monitor system performance, capacity, and stability
• Implement system changes, configurations, and integrations
• Work closely with vendors and third-party platforms
• Support release, change, and rollback processes
• Contribute to disaster recovery readiness and testing
• Maintain accurate technical documentation
• Drive continuous improvement and operational excellence
• Provide support and guidance to junior engineers

Education (Minimum)

• Grade 12 National Certificate / Vocational

Education (Ideal or Preferred)

• A relevant tertiary qualification in Information Technology

Minimum requirements

• 5+ years’ experience in a Systems Engineering / Production Support role
• Strong experience in at least one of the following:
• Payment’s systems
• Card processing environments
• Transaction switching platforms

Proven experience in:

• Production support and incident investigation
• System implementation, configuration, and integration
• Performance, capacity, and stability analysis
• Monitoring, alerting, and observability
• Change, release, and post-implementation validation
• Disaster recovery support
• Solid technical foundation in:
• Linux and/or Windows servers
• Networking, load balancing, and certificates
• SQL, AWS, microservices and relational database investigation
• Experience working with vendors and third-party platforms
• Strong documentation and operational discipline
• Must be willing to take part in a rotational standby/on-call support schedule

What Will Make You Stand Out

• Hands-on exposure to payments platforms (e.g. Postilion, ACI, PowerCard, UPF)
• Knowledge of ISO 8583, Visa/Mastercard, clearing & settlement
• AWS or cloud experience (EC2, VPC, IAM, S3, CloudWatch, etc.) 
• Familiarity with AI-assisted engineering tools (e.g. ChatGPT, Claude) for troubleshooting, scripting, or documentation

Beneficial Experience

• Exposure to EMV, ecommerce, wallets, or tokenisation
• Especially relevant as the team explores modernisation and potential migration of platforms (e.g. Postilion) to AWS
• DevOps and automation exposure (Git, CI/CD, Terraform, CloudFormation)
• Monitoring tools such as Splunk, Grafana, or Instana
• Exposure to microservices, Kafka, Docker, Kubernetes
• Basic scripting or automation capability
• Awareness of PCI-DSS, HSM, or payment security practices
• Experience in banking or financial services environments
