About SonicPrecision Every year, more than 100,000 patients in the US and Europe undergo catheter ablation for ventricular tachycardia, a heart rhythm disorder that can be fatal. Most procedures happen without real-time tissue feedback: the electrophysiologist burns the tissue, ends the procedure, and hopes that the lesion has reached the source of the arrhythmia. In published studies, up to 50% of patients have the arrhythmia back within a year.
SonicPrecision is changing that. We integrate a near-field ultrasound sensor into the tip of the ablation catheter. The sensor shows the electrophysiologist what is happening inside the tissue while the procedure is still running. For the first time, the physician can confirm that a lesion is deep enough before ending the procedure.
We are a Philips spin-out, based in Eindhoven, with an exclusive, worldwide licence to the relevant Philips patent families. Our pre-clinical programme runs in partnership with CARIM at Maastricht University and TU Eindhoven. Our next milestone is First-in-Human: the very first use of the device in patients.
The role This is a junior to mid-level role for a hands‑on engineer who wants to take a medical device from the bench to the clinic. You work directly with the founders and our System Engineer to build, integrate, and test the catheter prototype system: first on the bench, then in a pre‑clinical setting, then scaled toward First‑in‑Human. You will be making design decisions that set the architecture of a system that will eventually enter patients.
You will:
Design, build, and test the prototype catheter system and the testing infrastructure for evaluation on the bench and in pre‑clinical environments
Make design choices that think ahead about CE marking, sterilisation, and single‑use requirements, so the step to a clinical system is a scaling exercise, not a redesign
Develop and validate signal processing algorithms to extract tissue characterisation information from the raw ultrasound data
Work with external suppliers and contract manufacturers in hardware, catheter integration, and electronics miniaturisation
Work with CARIM / MUMC+ on the pre‑clinical study setup, making sure the prototype is ready for the animal lab and signal quality meets study endpoints
Structure technical documentation (requirements, specifications, design files, test reports, risk management) aligned with ISO 13485 and IEC 62304 from day one
What we are looking for
Education:
Master’s or PhD in electrical engineering, biomedical engineering, mechanical engineering, or a closely related discipline
Experience:
1-3 years in medical device development, research instrumentation, or a related hardware / embedded systems environment; if you have just graduated and did a strong medtech graduation project, please apply
Technical skills:
Hands‑on across hardware, signal processing, and software integration; proficiency in Python, MATLAB, C / C++, or equivalent
Domain affinity:
Familiarity with medical devices, ISO 13485, IEC 62304, or catheter / minimally invasive device development is a clear advantage
Communication:
Able to write clearly and present confidently to clinicians, regulators, and investors. Fluent in English.
Mindset:
Comfortable in an environment where not everything is defined yet, and energised by working in a small team where your work is directly reflected in the product
What we offer
You personally build a device that goes into patients to improve their lives
Stock Appreciation Rights: you share in the equity upside of the company you help build
Direct mentoring by our System Engineer: learn near‑field ultrasound sensing, catheter integration, and the regulatory route to First‑in‑Human
A salary that matches your experience, reviewed every year
25 holiday days, the Dutch 8% holiday allowance, and a travel allowance
Access to research facilities at TU/e and MUMC+
Room to grow: a personal development plan, and a role that grows as the company grows
A flat, small, international team, flexible hours, and a 40‑hour week in which results count, not hours logged
Practical details
Location:
Eindhoven, mostly on site because you build hardware; about one day a week from home
Contract:
Full‑time; a one‑year contract to start, with the clear intention to extend it
Start date:
As soon as possible; ideally Q4 2026
Application deadline:
1 November 2026; we review applications on a rolling basis
Right to work:
You must already have the right to work in the Netherlands; we are not able to act as a recognised sponsor at this stage
Apply with your CV and a short motivation letter. Half a page is enough: tell us why this problem interests you and what clinical or research experience you bring. Questions first? Contact René Aarnink (CEO) at rene@sonicprecision.us or Joanneke Groen (CPO) at joanneke@sonicprecision.us.
