Description of the context

The Directorate-General for Persons with Disabilities (DG HAN) is a directorate within the Federal Public Service Social Security and contributes to an inclusive society. Their goal is to increase the autonomy of persons with disabilities by assessing the impact of a disability on daily life and compensating for it through services. They support persons with disabilities by granting allowances and other rights, such as financial support, parking cards, and certificates for applying for benefits from other services. They are also committed to making these rights accessible to persons with disabilities and granting them fairly, so that everyone has the best possible experience when exercising these rights. Currently, around 600,000 people are recognized as having a disability, of whom 240,000 receive an income replacement allowance and/or an integration allowance every month. 514,000 parking cards are in circulation. In 2024, 160,722 disability assessments were carried out.

In 2019, the Council of Ministers decided that DG HAN could replace the existing back-office application (TETRA) with a new, modern application (TRIA). The transition to a new application is crucial because TETRA is outdated and uses technologies that are no longer supported. At the same time, DG HAN must continue to fulfill its mission to citizens.

The TRIA program is extensive and therefore consists of several subprojects. The largest subprojects are Product and Revision Handling, Handi2Pay, and the accessibility for citizens through the web portal myHandicap.

This request relates to the Product and Revision Handling team. For this team, we are looking for 2 profiles:

• A senior functional analyst
• A senior full-stack developer

This request specifically concerns the position of senior full-stack developer.

The assignment takes place in an Agile context within a scrum team of about twenty people (functional analysts, architects, developers, UX designers).

Description of the assignment

Product and Revision Handling (PRH) is a component of TRIA and is responsible for all processes related to the products and rights to which a person with a disability may be entitled.

Within this assignment, the intention is that the PRH backlog is translated into a concrete sprint plan. In consultation with the business (Product Owners and business experts), priorities are determined so that the desired functionalities can be developed according to the Agile methodology.

For this, we are looking for two additional profiles, with the necessary knowledge and experience, who will be part of the existing team. The ability to quickly familiarize oneself and integrate into the team's way of working is expected.

Given the complexity and urgency of the program, its intertwining with internal and external modules, and its specific subject matter, we are opting for individuals who have demonstrable experience with the context of social security systems, or at least other equivalent government institutions.

Collaboration

We expect the supplier to use a structured and transparent approach in executing the assignment. It is essential for us that the assignment is carried out in a planned and manageable way, with an explicit focus on achieving concrete results within the expected time limits.

The supplier is asked to work according to an end-to-end approach, in which working functionalities are delivered in each sprint (2 weeks). Through short feedback loops, the end product must be continuously aligned with the wishes and needs of the business and the other teams responsible for the business logic (e.g., Handi2Pay or Portal). This enables us to flexibly adjust priorities based on new insights or changing circumstances.

Throughout the entire process, close and transparent collaboration between client and supplier is crucial. This involvement enables us to respond quickly to changes and ensures maximum agility in the project flow.

Formal milestones and changes in the project—such as adjustments in scope, phase completions, architecture changes, or production releases—may take place after prior alignment with relevant stakeholders.

Transparency and open communication are prerequisites for us for successful execution. Timely and honest dialogue makes it possible to identify and effectively address bottlenecks at an early stage.

In this project, we strive for a careful balance between scope, budget, and lead time. Changes in one of these elements may impact the other two. It is therefore important to think in terms of a Minimum Viable Product (MVP), where the core functionality is realized within the available resources, leaving room for later expansion.

The working regime applied in this assignment:

• Full-time (8h/d) commitment for 160 working days (until the end of 2026)
• At least 2 days/week presence at the office (FINTO Tower BXL), unless another agreement is made during execution (Tue and Thu)
• Possibility to work remotely on the other days
• At release moments (3x in 2026), it may be requested to remain on stand-by
