R&D Engineer

Xeltis builds implants that the body gradually replaces with its own living tissue, restoring natural blood vessels instead of relying on permanent artificial parts. It is bold, first-of-its-kind engineering, built on Nobel Prize-winning science.

And it is now on the market. In April 2026 we received the CE mark for aXess, our restorative vascular access conduit for hemodialysis patients. That moved Xeltis from a clinical-stage company to a commercial one, and it changes what we need from our engineers. We are past proving the science works. The job now is to scale a product that is already reaching patients, where every design decision carries a manufacturing, cost, regulatory, and commercial consequence. We earned that CE mark in 84 working days, well ahead of schedule. That pace is who we are.

We are looking for an R&D Engineer to help us build and scale at that level.

What you’ll do

A hands-on engineering role that runs at commercial pace. Working alongside our senior and principal engineers, you will drive sub-projects across the full development cycle of Class III cardiovascular implants, always against real regulatory and commercial milestones:

• Design and develop bioresorbable vascular implants with embedded nitinol stents

• Plan and run bench, fatigue, and verification and validation testing that unblocks regulatory and commercial milestones

• Build prototypes and drive the transfer from design into manufacturing at scale

• Create audit-ready technical documentation: design history files, IFUs, SolidWorks models

• Contribute to risk management and root cause analysis (ISO 14971, FMEA)

• Work shoulder to shoulder with RA, QA, Operations, and Clinical to hit design reviews and get product to market

What you bring

• A build-to-ship mindset. Your energy comes from products reaching patients, you make decisions under deadline, and the regulatory, cost, and manufacturability limits of a commercial product are part of the engineering you enjoy.

• A Bachelor’s or Master’s in engineering or a related science

• At least 2 years of engineering experience, including 1+ year developing Class II or III medical devices

• Hands-on familiarity with an ISO 13485 design-control environment

• Sharp analytical thinking, precise documentation, and a real drive to crack hard technical problems

• Fluent English

Nice to have

Experience with bioresorbable or absorbable polymers, nitinol or other shape-memory alloys, vascular implant or stent development, and SolidWorks.

Be honest with yourself before you apply

This role is probably not for you if:

• You want open-ended research with no ship date

• You see regulatory, cost, and manufacturing limits as obstacles rather than the job

• You would rather perfect one thing slowly than move a product forward

We have left the pure research phase behind. If that phase is the part you love, you will feel the wall here fast, and neither of us wants that.

Where this role can take you

This is a role you grow from. Our engineers move along a clear path: Engineer, to Senior, to Principal, and beyond. You will learn directly from people who have taken novel cardiovascular technologies all the way to patients, and you will own more scope as you deliver.

Why Xeltis

• Join at a real inflection point: a commercial-stage company scaling a CE-marked product

• Work on technology that could change the lives of millions of cardiovascular patients

• A growing, international team of around 60 people who take the science seriously, move fast, and are easy to work with

• Real ownership, fast decisions, and the chance to see your work reach the clinic

• A culture built on five values we actually use: innovate, listen, grow, act, and joy
