Python Developer


The Linkage platform is a multi-tenanted SaaS platform used by corporates and SMMEs so that corporates can identify suitable SMMEs to develop them into suppliers for the corporate.

The platform is built using the following technology stack:

  • Flask framework (Python 3.6) hosted on AWS Fargate ECS;
  • PostgreSQL hosted on AWS RDS;
  • React hosted on CloudFront;
  • CloudFormation, CodeBuild, CodePipeline, and CodeCommit for CI/CD and VCS.

The solution consists of other AWS services to ensure that it satisfies enterprise-grade requirements.

Our team runs on a hybrid model where software development is outsourced and product management, project management, and business analysis are performed internally. The outsourced team consists of 3 Python developers and 1 React developer.

We are looking for a Python Flask developer with experience deploying and maintaining services on AWS infrastructure who will be the first member of our internal software development team. You will work closely with the outsourced team under the guidance of Linkage’s CTO.
