Job description

Founding Mechanical Engineer — Medical Device Start Up

Paris, France | Full-time | On-site

We are a venture-backed medtech company developing a minimally invasavice, at-home blood-monitoring platform.

This novel, automated system is designed to collect and analyze blood microsamples at home, monitoring various biomarkers for hig-risk patients that allow clinicians to understand patient dynamics, adjust treatments and respond quicker when interventions are needed.

The role

We are looking for a hands-on mechanical engineer to take ownership of a core part of our product: the blood-collection device and its disposable components.

You will work directly on the architecture, design, prototyping, and testing of a complex medical device, taking ideas from early concepts through to robust, manufacturable solutions.

This includes:

• Designing mechanisms and components from first principles
• Building and testing prototypes
• Solving challenges involving tolerances, materials, sealing, actuation, and fluid handling
• Designing test rigs and characterizing system performance
• Investigate failures and translate findings into design improvements
• Work closely with suppliers and manufacturing partners
• Move designs from rough prototypes toward a reliable medical product
• Challenge assumptions and take ownership of technical outcomes

Who we are looking for

We care more about what you can build than where you studied or which credentials you hold.

You may be a strong fit if you have built complex physical systems and are energized by difficult, multidisciplinary engineering problems.

We value:

• A strong bias toward building, testing, and learning quickly
• High agency and genuine ownership
• Exceptionally high standards for product quality
• An obsession with understanding why systems work or fail
• A willingness to challenge conventional solutions
• Comfort working in the ambiguity and intensity of an early-stage company
• The conviction that an idea is only impossible once it has been rigorously tested

Experience with medical devices, microfluidics, precision mechanisms, disposables, or regulated product development is valuable, but not essential.
