This position requires a strong background in Kubernetes internals and Golang programming, particularly in developing and managing Kubernetes controllers. If you’re a proactive problem solver with experience in building cloud-native infrastructure, this is your opportunity to contribute to a transformative platform.

We highly encourage candidates with a solid programming foundation and a hunger to explore the cloud-native world to apply. Comprehensive onboarding and professional development support will be provided.

Key Responsibilities (Not limited to):

• Collaborate in Agile teams, taking ownership of development stories with minimal supervision.
• Partner with internal teams and clients to accurately capture technical requirements.
• Design, build, deploy, and maintain Kubernetes controllers and operators using Golang.
• Identify gaps in current systems and propose or implement technical improvements.
• Apply best practices across the full software development lifecycle.
• Create and execute unit, regression, and E2E tests for operator reliability.
• Work in Linux environments and troubleshoot issues in containerized applications.
• Contribute to CI/CD workflows for seamless testing and deployment.

Essential Skillset:

• Kubernetes Controller Development: Proven expertise in building and maintaining controllers and operators.
• Proficiency in Golang: 2+ years writing idiomatic, well-tested Go code for Kubernetes projects.
• Deep understanding of Kubernetes APIs and libraries including client-go, CRDs, and API extensions.
• Hands-on experience with:
  • Kubebuilder – For scaffolding controllers and CRDs
  • Operator SDK – For building Operators with OLM support
  • controller-runtime – For abstracting Kubernetes client logic
• Strong testing skills, including unit, load, and E2E tests for operators.
• Familiarity with containerization (Docker) and orchestration (Kubernetes).
• Comfortable working in Linux with debugging tools and CLI.
• 2+ years experience working with CI/CD tools like Jenkins, GitHub Actions, Tekton, or similar.

Preferred Skills (Nice to Have):

CKA or CKAD certifications.

Hands-on experience managing production-grade Kubernetes clusters.

Knowledge of Infrastructure as Code tools (e.g., Terraform).

Exposure to major cloud providers: AWS, GCP, or Azure.

Scripting experience in Shell or Python.

What We Offer:

A chance to build infrastructure automation tools that power real-world workloads.

Opportunity to work on bleeding-edge cloud-native technologies with a global impact.

Collaborative and innovation-driven culture, with strong engineering mentorship.

A Remote-friendly setup and flexible work culture.
