About the Role

We are seeking a highly skilled Senior Software Developer to join our team in Johannesburg. As a key member of our engineering team, you will be responsible for building secure, observable, scalable services and clean front ends, contributing to architecture, and raising the engineering bar (standards, patterns, CI/CD, code quality). You will work across C#/.NET, TypeScript (Node React/Next.js), and AWS with emphasis on event-driven microservices, API-first design, and sales/dialer integration via Amazon Connect.

  • Implement .NET 8 and js microservices with clean architecture, CQRS/MediatR, EF Core (MSSQL/Postgres), and Open API-first contracts
  • Build React/Next.js apps with strong state management (Zustand/Redux), TanStack Query, and component libraries with design tokens
  • Implement event-driven patterns using AWS EventBridge, SNS/SQS, and idempotent consumers
  • Create robust APIs (REST; GraphQL a plus) secure with OAuth2/OIDC and JWT
  • Integrate Amazon Connect (IVR, CTI, call recording, agent states, dispositions) with CRM/Sales workflows and near-real-time analytics
  • Deliver infra-as-code (AWS CDK/Terraform), GitHub Actions pipelines, and trunk-based development with feature flags and blue/green or canary deployments
  • Apply observability by design: structured logs (Serilog), metrics (Prometheus/CloudWatch), tracing (OpenTelemetry), dashboards, and actionable alerts (SLIs/SLOs)
  • Optimize cost, reliability, and performance (caching, connection pooling, async messaging, retries/backoff, circuit breakers)

Requirements

  • Bachelor’s degree in computer science, software development, or related field
  • 10 Years of Software Development Experience
  • Experience with CI/CD pipelines and DevOps practices
  • Exposure to Agile/Scrum methodologies
