Project overview

Assignment Description

The Low-Code Component Engineer develops, manages, and optimizes reusable components within a low-code platform. These components form the building blocks for applications developed by DevOps teams.

Background Assignment

Additional Information

When you, as a supplier, offer a professional to us and they are placed, we will need information from you as a contracting party, including regarding the Chain Liability Act (Wet keten- en inlenersaansprakelijkheid). The purpose of the 'WKA' is to prevent abuse in the remittance of payroll taxes at all links in the chain; from supplier to client. We cover these risks for our clients by means of a blocked account, the G-account. This is an account to which a portion of the invoice amount is deposited and from which you can pay payroll taxes and VAT to the Tax Administration.

The percentage to be deposited depends on whether you have SNA certification (NEN-4400-1 or NEN-4400-2) and whether your company is located in the Netherlands or abroad. You can apply for the G-account from the Tax Administration. If you cannot obtain a G-account (and you can provide proof from the Tax Administration), you also have the option to provide an accountant's statement (assurance report regarding personnel lending) every quarter. In this, a certified accountant (AA or RA) will issue a statement about the correctness, completeness, and timeliness of the remittances.

Please note that the costs for this statement are at your own expense.
