Build a Custom Kubernetes Operator for a Multi-Tenant SaaS
Overview
What this challenge is about.
Build a Custom Kubernetes Operator for a Multi-Tenant SaaS. Advanced challenge in code. Writing production code that solves real engineering problems, earn a...
The Brief
What you'll do, and what you'll demonstrate.
Ship a Kubebuilder-based Kubernetes operator that manages per-tenant Kafka topics, schemas, and consumer groups via a TenantPipeline CRD, replacing brittle Helm + bash glue.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Design a CRD that captures real multi-tenant requirements
- Implement an idempotent reconcile loop with finalizers
- Add operator observability (logs + metrics) cleanly
- Test operators with envtest and a small real cluster
