“It’s not as if you’re saving lives.”

At Haermonics you will be. As a clinical stage medtech company developing innovative therapies to prevent post-operative cardiac surgery complications. What we do matters. What we do actually does save lives. Not a bad motivation to get going every morning.

In fact, every day 250 patients die from postoperative heart surgery complications caused by residual blood and clots in the pericardial cavity. Complications that we can help prevent. That’s why we’re looking to expand our teams with these positions:

Our innovation isn’t even on the market yet… and we’re already saving lives!

We’re happy to say that our PURE-AT-HEART recruitment campaign has raised €2500 for the Dutch Heart Foundation (Hartstichting) and its life-saving research!

And we’re looking forward to some super new Haermonics hires!

The flushing method will be performed in the FLUID trial with a newly developed, automated Investigational medical Device (ID). The ID will regulate the inflow and heating of flushing fluid and record pericardial pressure and blood loss. The primary focus will be on the effect of flushing on the number of reoperations.Under the supervision of drs. Eva Diephuis MD, researcher and assistant cardiac surgery of the participating hospital in (LUMC, AMC, Antonius, Catharina), you participate in the FLUID trial, part of the CPPF project.We are looking for students who can contribute to the research 4-10 times a month by building the device, connecting it to the patient in the OR (and experiencing the last hour of the heart surgery) and then for 8 hours guide the process in the ICU and enter research data. Approximately 10 hours of work per participating patient.We are looking for

  • Student in second year of study or further
  • Affinity with cardiac surgery
  • Affinity with innovation and technology

We offer

  • Paid work/learning place of about 12 months, €10/hour
  • Possibility to watch the cardio-surgical OR
  • Deepening in cardiac surgery and medical technology
  • Gain experience with multicenter clinical research

Haermonics has recently attracted 2 new investors, amongst whom BOM capital, a regional investor. In order to prepare itself for the next phase, market introduction, the company is following a “Customer Development Program”. The objective of this strategic program is to determine, within the Decision-Making Unit of their customers and prospects (mainly Thoracic Surgeons, Anesthetists and Intensive Care staff), which segments and customer groups are primary target, what are the product features needed, determine the proof points per customer segment and in the end to determine the go-to-market strategy.

The strategic program is conducted by the CEO and executed by the full team. The BOM, shareholder, is supporting and guiding this program and has in depth knowledge of the program to share. During this program, many interviews with doctors, nurses and other medical staff will need to be executed and a project secretary is needed, for the duration of 3 months. Objective is to start early in February 2022.

The Assignment

The first step in the Customer Development journey has been conducted by the company, together with a trainee Technische Geneeskunde, concentrated on the Netherlands. The conclusion of this first step was a clear problem definition, market segmentation and target segment in the Netherlands. Now, the market has to be validated internationally. Haermonics has chosen Germany, France and the USA as its first market entry points. In these countries, the market has to be validated.

The question is which beachhead applications offer the best opportunity for a successful commercialization, whereby cost savings, outcome improvements and ease of positioning of the solution (to the many stakeholders in the decision process, such as end-users, deciders, influencers, buyers, champions, etc.) in the market are the most likely key drivers. In the first step of the project, two applications will be chosen by the intern in consultation with and subject to approval by a support team, consisting of:

  • CEO of the company, clinical support
  • Business developer of BOM for methodology support

After that, for the three chosen countries, interviews will be conducted with several stakeholders in several hospitals worldwide. During these interviews the customer problems (needs) will be investigated and validated (including the differences in needs between the various stakeholders);

  • the extent to which the device can address the problem
  • the assumptions will be validated and/or a plan will be made to validate these assumptions
  • the differences between the several segments of hospitals and labs is clarified.

Based on this extensive body of evidence, the positioning of the device to the various stakeholders, in the various segments of hospitals and labs, will be defined.


The assignment contains the following elements:

  • Familiarize yourself with the workflow and treatment in hospitals
  • Familiarize yourself with the work done by the previous trainee and build further on the work done – the recommendations is the starting point of this traineeship
  • Investigate for those applications, through desk research, market research and interviews, the customer problems (needs), including the differences in needs between the various stakeholders and the differences between customer segments
  • Describe how device can address these problems and validate the underlying assumptions and/or make a plan to validate these
  • Identify bottlenecks/barriers/opportunities in relation to the current workflow in thoracic surgery and treatment in hospitals
  • Define the positioning of the device to the various stakeholders, in the various segments of hospitals
