Johannesburg: Senior DevOps Engineer posted by iOCO Digital Pty Lty

We are seeking a highly skilled and experienced DevOps Engineer with strong AWS expertise to join our client project team. This role will focus initially on developer enablement and CI/CD pipeline optimisation, and then evolve into broader infrastructure automation and operations as the platform matures. The ideal candidate will bring hands-on AWS experience, automation-first thinking, and a passion for enabling development teams through reliable, scalable, and observable infrastructure.

What you’ll do:

• Assess the current pipeline and infrastructure setup; recommend and implement improvements aligned with industry best practices.
• Design, implement, and maintain CI/CD pipelines using AWS-native services (CodePipeline, CodeBuild, CodeDeploy, ECR).
• Build and manage infrastructure as code (Terraform, CloudFormation, AWS CDK) and increase IaC maturity across the environment.
• Automate deployments, provisioning, monitoring, and incident response processes.
• Enable developer productivity by reducing deployment friction, providing templates, scripts, and self-service tooling.
• Design, develop, test, and deploy serverless applications (AWS Lambda) and containerised workloads (ECS/Fargate).
• Improve observability using monitoring and logging tools (CloudWatch, X-Ray, ELK stack).
• Work with microservices architecture (Aurora Postgres backend, ECS containers, modular reusable services).
• Provide guidance and mentorship to junior team members.

Your Expertise:

• Strong practical AWS experience (S3, ECS/Fargate, RDS/Aurora, ECR, IAM, Redis, VPC, Parameter Store/Secrets Manager, WAF).
• Solid knowledge of containerisation technologies (Docker, ECS; Kubernetes experience beneficial though not in current use).
• Proficiency in Infrastructure as Code (Terraform, CloudFormation, AWS CDK).
• Strong scripting in Python, Bash, or similar.
• Experience designing/building CI/CD pipelines and automating infrastructure from scratch.
• Familiarity with Java/Tomcat applications (bonus).
• Hands-on experience with monitoring/observability (CloudWatch, ELK, X-Ray).
• Experience with SQL/NoSQL databases.
• Strong problem-solving skills and ability to stabilise infrastructure under scale.
• AWS Certification (Solutions Architect, DevOps Engineer, or similar).
• 35 years experience implementing AWS automation pipelines.
• Familiarity with Step Functions, certificate automation.

Attributes:

• Tenacious and results-driven with the ability to build and manage infrastructure from scratch.
• Data-driven engineering mindset.
• Strong communicator to both technical and non-technical audiences.
• Self-motivated, collaborative, and able to mentor others.
