• Work with non-relational databases and data stores such as Redis, MongoDB and Elasticsearch

6. Containerization and Deployment (Value-Add)

• Containerize .NET applications into optimized OCI images using multi-stage Dockerfiles or .NET SDK container publishing

• Build, run and troubleshoot container images on the containerd runtime (e.g. nerdctl, crictl), as used in K3s/RKE2 clusters

• Publish and manage images in private container registries (e.g. Harbor, Nexus), including in air-gapped environments

• Deploy and manage containerized .NET workloads on Kubernetes (K3s/RKE2) using Helm charts or manifests, with health probes, ConfigMaps and Secrets

Qualifications

Education & Experience

• Bachelor’s degree in Computer Science, Information Technology, Engineering, or a related field.

• Minimum of 5 years of hands-on experience in software development using C# and .NET technologies.

• Experience building and packaging .NET applications as container images (Docker/containerd) and deploying them to Kubernetes is a strong value-add.

• Experience in hardware/device integration is an added advantage.

• Familiarity with rules engine development is an added advantage.

• Prior experience with code quality control practices such as code reviews and static code analysis (e.g. SonarQube).
