    Company:E-Merge IT Recruitment

    My client is looking for a Senior Backend Engineer.

    Not someone who can quote architecture patterns from conference slides. Someone who's worked with them in the real world.

    You've seen microservices accelerate a business—and you've seen them turn into a maze of unnecessary complexity. You've built and operated distributed systems at scale. You've investigated production incidents, fixed critical issues under pressure, and learned that every architectural choice comes with trade-offs.

    You understand that great engineering isn't about applying patterns everywhere—it's about knowing when they add value and when they don't.

    You'll likely thrive here if you have:
    • 8–10+ years of experience building and operating production-grade backend systems
    • Strong hands-on expertise in:
      1. Microservices
      2. Domain-driven design (DDD)
      3. Test-driven development (TDD)
      4. Event-driven architecture
      5. CQRS
      6. .NET / C#
      7. TypeScript
      8. Go
      9. Node.js
      10. Saga patterns
      11. Circuit breakers
      12. Clean architecture
    • The judgment to know when not to use these approaches
    Bonus points for:
    • Frontend experience with React, Next.js, or similar frameworks
    • Production experience with AI-powered systems, including:
      1. LLMs
      2. Retrieval-augmented generation (RAG)
      3. AI agents
      4. Evaluation frameworks
      5. Model context protocol (MCP)
      6. Vector databases
      7. Prompt engineering
      8. Cost optimization
      9. AI observability
    • Experience leading small engineering teams, mentoring developers, or owning a product domain end-to-end

    Deep experience with cloud-native platforms and practices:
    • AWS, GCP, or Azure
    • Containers and orchestration platforms
    • Infrastructure as code (IaC)
    • CI/CD pipelines

    Reference number for this position is PM61391 which is a contract position offering a contract rate of R760 per hour negotiable on experience and ability. Contact Phindi on az.oc.egrem-e@melidnihp or call him on 011 463 3633 to discuss this and other opportunities.
