To ensure your application is successfully received and that you can smoothly complete the screening process, we encourage you to apply through our Career Portal:www.ecentric.co.za. We look forward to reviewing your submission! Introduction: Our team offers comprehensive experience and expertise across the South African (and beyond) payment gateways landscape. To guarantee the best service, we handle all the one-to-many payment relationships on behalf of our clients so they may focus their energy on growing their business. As leaders in payment compliance and security, our clients can have the peace of mind that their payment processing needs are met efficiently with absolute security. Position Overview: Ecentric Payment Systems is looking for senior full-stack engineers on a 12-month contract to build and run features on our payments platform. The platform is event-driven and multi-cluster, and is built on open standards so that it can run on Azure or on-premise infrastructure. The work covers backend services and APIs, and self-service web portals for merchants. Core stack: C# / .NET, Angular, PostgreSQL, Kafka, Redis, Kubernetes, Azure DevOps. Roles and Responsibilities: Build and run features end to end, within a squad or as the sole engineer on a slice of the platform. Backend (.NET): build API and orchestration workers, webhook dispatch and adapters to downstream systems (BankServ, Postilion, vendor integrations), using patterns such as transactional outbox, idempotent consumers and durable timers. Frontend (Angular): build the merchant and organisation portal and customer-facing payment pages (redirect and embedded iframe modes), including white-label branding. Data (PostgreSQL, Redis): design schemas, write migrations and tune queries, with a working grasp of replication, failover, backup and connection pooling. Platform: deploy to Kubernetes with Helm or Kustomize, run CI/CD in Azure DevOps, and build dashboards and alerts on OpenTelemetry and Prometheus. Portability: keep provider-specific code behind interfaces, so the same build runs on Azure and on-premise with configuration changes only. Requirements We encourage all applicants to carefully review the required skills, competencies, and education levels outlined in the job description. This ensures that we can focus on candidates with the right qualifications, leading to a more efficient and accurate evaluation of your application.
