How do companies find specialized STEM professionals?

Within a few weeks, a highly specialized medium-sized company in southern Germany needed to fill a key position in its internal research department. They weren’t looking for a traditional resume or a narrowly defined specialization, but rather a person with scientific depth, experience, and the ability to grow into an existing team over the long term: a classic “hidden gem.”

It is precisely these kinds of recruitment processes that pose some of the greatest challenges for technology-driven companies today. When it comes to highly qualified STEM professionals in particular, traditional outreach methods are often no longer sufficient—especially when positions are particularly demanding and candidates are rarely actively looking for work.

As a specialized recruitment firm for research, development, and technology-oriented companies, Professional Scientists has been helping clients fill precisely these types of challenging roles for many years. Using real-world examples from various projects, we demonstrate what really matters when it comes to hard-to-fill positions.

The company featured in our first case study is headquartered in the heart of a major city in southern Germany: no longer a startup, but still far from being a long-established player in the business world. Young, ambitious, with flat hierarchies, and committed to maintaining an open and collaborative work environment. At the same time, the company operates in a highly specialized field, is growing steadily, and is already one of the leading players in its market.

When Professional Scientists was tasked with identifying suitable candidates for the company’s internal research at short notice—that is, within a few weeks—it quickly became clear that the company had a clear vision. Through discussions with the decision-makers, a demanding profile emerged: The company was not looking for a narrowly defined technical specialization, but rather for a professional with strong technical expertise who would effectively complement the existing team and integrate into the corporate culture over the long term—a classic “hidden gem.”

This situation is not unique. Many companies face the same challenge: How do you fill hard-to-fill STEM positions when both technical expertise and a good personal fit are crucial?

The answer rarely lies in greater reach, but almost always in greater precision. Accordingly, the search process was deliberately designed to be focused. Instead of a broad outreach, the emphasis was on targeted direct outreach and careful pre-selection, supported by a specialized network in academia and research that has grown over the years.

This network is based, on the one hand, on long-standing relationships with highly qualified academics—both domestic and international—and, on the other hand, on a talent pool that is continuously maintained within our own database. Many consultants at Professional Scientists also bring with them established networks from their previous positions. The key to building these relationships lies not so much in sheer reach as in a personal and trust-based approach to work. A resilient network is not built through fleeting contacts, but through listening, genuine interest, and a long-term, empathetic exchange.

We then reach out to potential candidates through various channels, including professional networking sites such as LinkedIn or XING, personal referrals, or applications in response to our job postings. How quickly we identify suitable candidates depends heavily on the specific search assignment. In some cases, suitable candidates can be identified very quickly because the team knows its own database well and already has suitable candidates in mind. For particularly specific requirements, the search can take up to six months.

In this case study, we focused our search internationally from the very beginning. After all, we needed to fill the position quickly despite a very demanding job profile. At that time, the candidate who was ultimately selected was already in a permanent position abroad. Consequently, the entire cross-border application process required a high degree of coordination, flexibility, and precise timing.

International and highly specialized hiring processes, in particular, highlight just how crucial a structured and personalized selection process is. At Professional Scientists, the initial contact is typically followed by several in-depth interviews that focus not only on the candidates’ professional qualifications but also on their motivation, work style, suitability for the industry, and personal goals.

The goal is not only to present candidates who are a good professional fit, but also to create long-term matches. That’s why the team deliberately takes the time to conduct interviews. This allows expectations to be clarified early on, terms and conditions to be made transparent, and both professional and personal factors to be carefully weighed. Only then do we provide support in preparing application materials and introduce the candidate to the company.

In our search for our “hidden gem,” we consistently focused on the “personal fit”—that is, whether the candidate and the company are a good match not only in terms of professional qualifications but also for the long term.

As the interviews progressed, it became increasingly clear that it was not only the candidate’s professional expertise that was impressive, but also his personal qualities. Their work styles, expectations, and perspectives were a good fit on both sides. With each interview, the impression grew stronger that this could develop into a long-term match.

The candidate ultimately made a conscious decision to join the medium-sized company. However, the process was not complete once the contract was signed. Especially in the case of international hires, the phase that follows is often what determines long-term success. Issues such as relocation and organizational coordination play a central role. In this case, the candidate received close support to ensure as smooth a transition as possible. This included assistance with the move as well as, in some cases, help with the candidate’s partner’s career orientation.

To this day, our “hidden gem” continues to work for the company, and both sides remain very satisfied.

Looking back, it wasn’t a single factor that led to success, but rather the interplay of several elements: a clearly structured selection process, a robust network, targeted direct outreach instead of broad casting, and, above all, a willingness to take the time for personal interaction. It was precisely this approach that made it possible to create a long-term, successful match despite the short-notice search and the client’s high standards.

If you’re currently facing a similar challenge or wondering how you can effectively reach specialized STEM professionals, it’s worth taking a fresh, outside perspective.
