Integration Developer

Project overview

Job Description

You work as a senior integration developer in the DevOps team Registers. In this role, you develop .NET backend solutions and design and build new APIs that create connections with external parties and chain partners. You actively contribute to the development of APIs and work with your team on innovative and reliable solutions. You will also be involved in redesigning and rebuilding existing webservices within a cloud-native microservices architecture. Because you work on internet-facing systems with sensitive legal data, privacy, security, and reliability are constant priorities.

As a senior integration developer, you are expected to take a leading role within the realization team. You take initiative in starting development activities, help guide the technical approach, and contribute to the quality and predictability of the delivery.

The main activities are:

In addition, you are expected to work independently, provide technical direction, and involve colleagues in choices and solutions. You easily switch between analysis, design, realization, and coordination with stakeholders, and you actively contribute to a well-functioning DevOps team.

Background of the assignment

As an integration developer, you are part of a DevOps team that will work on the realization of the Registers Roadmap. In this multi-year roadmap, various registers of the Judiciary are being prepared for digital connection to the primary processes of various chain partners, such as the CJIB, the Tax Administration, and municipalities. The data from the registers has high social value and should ultimately ensure that these chain partners can optimize their services to citizens. The Register team is part of the Public Service base.

The Public Service base realizes and provides services for external stakeholders of the Judiciary, such as citizens, lawyers, and other professionals. These are new services that are still under development as well as existing services. The various registers have different readiness levels: some are almost ready for digital connection, while others still require a significant technical upgrade. This team is not only technically skilled but is also focused on processes, service delivery, and the service surrounding data logistics and deliveries.

In many cases, this is done in co-creation and in collaboration with internal stakeholders and external chain partners. This interaction is essential for the success of the realization of the Registers Roadmap. During the realization, innovative software will be used. This includes continuous delivery, resulting in a constant stream of new features going to production, and enabling canary tests for the team. The DevOps team is not only responsible for the realization of new functionality but also for the functioning of the system in production (application management, resolving events and incidents).

• coordinating desired functionality with the information analyst and functional designer;
• preparing, modifying, and expanding technical design documentation;
• coordinating with fellow application developers, architects, and testers;
• contributing to analyses of findings and production or test issues;
• performing impact analyses;
• realizing functionality in .NET;
• performing system tests and code reviews;
• participating in refinement sessions;
• releasing your own work on the container platform;
• monitoring quality, security, and privacy within the technical solutions.

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 (Wet keten- en inlenersaansprakelijkheid). The 'WKA' aims 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 Authorities.

The percentage to be deposited depends on whether you have a 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 Authorities. If you cannot obtain a G-account (and you can provide proof of this from the Tax Authorities), you also have the option to provide an accountant's statement (assurance report regarding personnel lending) quarterly. In this, a certified accountant (AA or RA) will issue a statement on the correctness, completeness, and timeliness of the remittances.

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