We believe in enabling ownership at all levels of the organization and empowering teams. If you thrive in this culture, come join us!

Your Impact:

  • Design, build, and maintain core cloud-native platform services utilizing the Kubernetes control plane to enable rapid product development and high-scale deployment in a multi-tenant, distributed architecture.
  • Develop robust microservices using Ruby, Java, or Go, using Kubernetes and data services like PostgreSQL and Redis across Azure and AWS clusters.
  • Own the full development lifecycle including deployment, focusing on defining Kubernetes deployment strategies, ensuring comprehensive observability (Prometheus/Grafana), and implementing best practices for production reliability and critical issue resolution.
  • Enhance and manage multi-cluster CI/CD pipelines using Jenkins and automation, strictly adhering to GitOps principles (e.g., ArgoCD or Flux) for declarative configuration management across hybrid and multi-cloud Kubernetes environments.
  • Foster team excellence through mentorship and rigorous code reviews, driving adoption of Kubernetes security policies, resource optimization, and overall cloud-native best practices.

Your Toolkit:

  • Bachelor’s degree in Computer Science or equivalent, with 3–5 years of experience building distributed, scalable software and systems.
  • Strong coding skills in Ruby, Java, or Go, with experience building API-based web services and a desire to deepen expertise in Ruby.
  • Hands-on experience with PostgreSQL, Redis, or similar database and caching technologies.
  • Deep expertise in Kubernetes architecture and operations, with familiarity implementing GitOps workflows (e.g., ArgoCD, Flux).
  • Solid understanding of CI/CD systems (especially Jenkins), and experience working with Azure and AWS at the API/programming level.
  • Demonstrated analytical and debugging skills, with a passion for continuous learning and staying current with technological trends.
  • Excellent communication and collaboration abilities, thriving in team-oriented environments.

Bouns Points:

  • Experience with networking and network security controls.
