Usecase Veiligheidsregio Utrecht: Finding the Right Candidate Faster with AI-Driven Vacancy Optimization

Veiligheidsregio Utrecht (VRU) plays a crucial role in ensuring safety and crisis management for over 1.3 million residents in the region — covering everything from fire services to disaster response and crisis coordination. In a labor market where talent is scarce and candidates are becoming increasingly selective, attracting the right people is a growing challenge. Traditional recruitment approaches, such as posting vacancies and running standard campaigns, are no longer always sufficient to reach and persuade the right target audience.

That is why VRU is experimenting with new, data-driven ways of recruiting. This case study centers on a concrete example in which VRU, using the Giant Dashboard and its built-in AI assistant, managed to transform a vacancy from “difficult to fill” to successfully filled. It demonstrates how small adjustments, grounded in target audience insights and supported by AI, can make a significant difference in recruitment effectiveness.

"We noticed that a campaign alone wasn't getting us anywhere. So we shifted our focus to the content of the vacancy itself."

1. Challenge

The vacancy for the position of administrative secretary of the works council (OR) at VRU, a pivotal role in employee representation within the organization, had been open for over a month without attracting suitable candidates. An active LinkedIn campaign was running, but without the desired results. The challenge was not a matter of reach, but of relevance:

  • The job posting did not resonate sufficiently with the target audience
  • Key pull factors were missing
  • The tone of voice was not aligned with the target audience

"With Giant data and AI, we were able to quickly verify whether the text truly resonated with the target audience."

2. Approach

VRU used Giant data in combination with a Large Language Model (LLM) to optimize the job posting. First, the pull factors and desired employment conditions of the target audience were analyzed. The text was then rewritten with a focus on:

  • Relevant motivators
  • Stronger positioning of employment conditions
  • A fitting communication style

"By better aligning with what candidates value, responses started coming in right away."

3. Results

The impact of the optimized job posting was immediate: the revised text led to a direct improvement in both response rate and candidate quality.

  • Multiple strong candidates entered the hiring process within two weeks
  • The vacancy was filled within one month of making the adjustments
  • At the time of publishing this case study, the hired employee is actively and successfully working in her role

This case study from Veiligheidsregio Utrecht demonstrates that successful recruitment in today’s labor market is not just about visibility, but about relevance. Where the original job posting failed to connect with the target audience, the combination of labor market data and AI support delivered a clear breakthrough.

By gaining insight into what candidates genuinely care about and consistently translating this into tone of voice, content, and positioning, VRU was able to make the vacancy significantly more appealing and effective. The use of the Giant AI assistant made it possible to carry out this optimization not only faster, but with greater precision.

The outcome reflects a broader trend: organizations that base their recruitment and employer branding on data and audience insights considerably improve their chances of success. For VRU, this meant not only filling a difficult vacancy quickly, but also adopting a new way of working, one that relies less on assumptions and more on insight and evidence.

A relatively small shift in approach, with a significant impact on results.
