Pretoria: Senior Full Stack Developer (Java & Platform Engineering)

About the Role

Join our team as a Senior Full Stack Developer in Pretoria, where you will lead the design, development, deployment, and operation of microservices and platform capabilities on AWS EKS using Java 21 and Spring Boot. As a critical engineering leader, you will own critical engineering decisions across application and platform layers (runtime, CI/CD, observability, security), ensuring delivery quality, performance, reliability, and cost efficiency.

Key Responsibilities

• Lead the design, development, deployment, and operation of microservices and platform capabilities on AWS EKS using Java 21 and Spring Boot.
• Contribute to the definition and evolution of microservice and API architectures (domain boundaries, reliability patterns, security controls) using Java 21, Spring Framework/Spring Boot, Tomcat (embedded), and REST; apply concurrency/performance features where appropriate.
• Design, implement, and operate container platforms (Docker, Kubernetes) on AWS EKS including cluster provisioning, node pools, autoscaling, upgrade strategies, ingress, service mesh (if applicable), multi-environment topology, as well as networking, VPC, and subnet setups within the AWS tenant.
• Establish Infrastructure as Code (e.g., Terraform/CloudFormation), Gitlab pipelines (e.g., Argo CD/Flux), and golden path templates for services.
• Engineer solutions on AWS (e.g., EKS, EC2, RDS, S3, IAM, VPC, ECR, CloudWatch) with secure-by-default patterns (network segmentation, least privilege, secrets management).
• Own CI/CD for services and platforms (build, test, security scanning, artifact management, progressive delivery/blue-green/canary).

Requirements

• 10 years professional software engineering experience, with 5 years leading microservice design and delivery on Spring Boot in production.
• 5 years hands-on platform engineering with Docker/Kubernetes and AWS EKS (cluster operations, upgrades, autoscaling, ingress, observability).
• Proven ownership of mission-critical systems (high availability, disaster recovery, performance engineering).
• Demonstrable experience in CI/CD, automated testing (unit/integration/contract), and secure coding practices.
• Strong grounding in computer science fundamentals (algorithms, data structures, distributed systems).

Qualifications

• Relevant IT degree/diploma; advanced certifications advantageous (e.g., AWS Certified Developer/DevOps Engineer, Kubernetes certifications).
• Advanced degrees/certifications mentioned in the original job description (if any)
