About the job
Our Team: In the Accelerator's Platform Team
In a nutshell, a platform team is a team that creates the foundational layers and core building blocks of a company’s products. We do not provide direct value to the business, we do, however, support and help all other technical teams to focus on their productivity. The platform team is also here to find ways for multiple teams to work on a cross project that can be reused by all.
More concretely a platform can be at different levels of granularity:
CI configs and rules to be used by other teams
IaC, tooling to deploy and monitor resources in the Cloud
Development environment, tools and shared libraries
Help and can define global system architecture / security
Core abstractions (data model, business modeling) API/SDKs
