Python Developer

Our organization is looking for a Python Developer to lead the strategic development of our cloud-based digital platform – Linkage.

One Linkage, a woman-owned and led technology company that builds technologies that make it easy for corporates to work with SMMEs.

Linkage is an end-to-end SaaS digital platform designed to make it easy for corporates to onboard, manage, track development, and report on the integration of SMMEs into supply chains.

Linkage has automated and digitalised the processes and workflows required by supply chain, corporate affairs, finance, and sustainability.

It enables the collaboration and transparency required to support SMME integration into the supply chain.


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.

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.
