Job Description

Who are we? 🚀

We have built a SaaS solution to help business owners and HR professionals save time and money allowing them to refocus on what really matters: their employees. Through PayFit, employees have a dedicated access for their payslips and are able to manage efficiently their leave and expense requests. To build such a solution, we have created our own programming language : JetLang.

We have a strong presence in France since 2015 and have been quickly growing in Germany, Spain and the UK. We are now opening the service in Italy.

A brief overview of the JetLang Platform Tribe

The JetLang Platform is assumed as a low-code platform, it has been designed by Payfit and which has sustained Payfit’s growth. This is an abstraction layer designed and maintained by the JetLang tech Tribe, as some people (known as Product Builders) are modelizing/scripting collective labour agreements. The JetLang holds an “engine” being able to compute rules/conditions and whose main purpose is to run payroll.
And finally, we are offering various restitutions :

  • Ability to (dynamically) generate the UI.
  • Reports to companies and employees, the very first one being payslips.

The tribe is split into 4 squads :
Data and Compute : providing features to define the business data model, compute JetLang business rules and a layer to expose JetLang data.
Runner : providing UI facilities and input/output features.
Tooling : providing facilities to the Product Builders to build their own meta-code. Workflow : providing workflow facilities and BackOffice administration tool.
