Requirements:

 

  • 8+ years of hands-on experience developing and designing large-scale, distributed, cloud-based systems.

  • Strong experience with:

    • AWS and cloud-native architectures

    • Microservices and event-driven design

    • Containers and serverless patterns

  • Proactive, highly motivated, and goal-oriented mindset.

  • Excellent communication, collaboration, presentation, and problem-solving skills.

 

Nice to have:

 

  • Experience in cloud security domains.

  • Familiarity with Azure and/or GCP.

  • Experience influencing architecture in large SaaS environments.

  • Observability and reliability engineering experience.
