Nature-inspired Microengineering – MEMS with an strong simulation background About us We are developing Wear & Forget® wearables for continuous sweat biochemistry monitoring, combining on-demand sweat extraction with aptamer-based biosensing. Based at the Lausanne Biopôle, we are a small, multidisciplinary team of scientists and engineers (fewer than 20 FTEs) driven by a shared passion for impact. We thrive in a fast-paced, collaborative environment where creativity, scientific excellence, and rapid iteration are at the core of everything we do.
The role We're looking for exceptional PhD graduates, or final-year PhD candidates (graduating within the next 3 months), postdoctoral researchers, or early-career scientists to lead the physics, simulation, and microfabrication of one of our core technologies.
You have a strong background in Applied Physics, MEMS, Mechanical Engineering, Microengineering, or a related field, with hands-on experience in COMSOL Multiphysics, microfabrication, and experimental validation.
You'll lead the simulation-driven design of our wearable microsystems, develop fabrication processes at EPFL's CMi cleanroom, and work side-by-side with our electronics and biochemistry teams to transform nature-inspired physical principles into manufacturable medical devices.
This is not a support role. You'll be one of our first dedicated physics hires, owning a critical technology from first principles to functional prototypes. Your work will directly influence the product architecture and ultimately become technology worn by thousands of people.
We're especially excited to meet candidates who have worked on slippery surfaces, superhydrophobic systems, bio-inspired MEMS or microfluidics, transport phenomena and Multiphysics simulations, capillary-driven fluidics, and nature-inspired engineering.
The strongest candidates have already completed the full innovation cycle during their PhD or postdoc: developing physical models, building COMSOL simulations, designing devices, fabricating prototypes, experimentally validating results, and iterating until the technology worked and was published (first-author) in leading venues.
We value curiosity, scientific rigor, speed, and execution. We particularly encourage applications from exceptional researchers trained at leading universities and institutes worldwide—including ETH Zürich, EPFL, TU Delft, TUM, ICL, Koç and Sabancı, top 10 Chinese universities, and leading Korean research institutes, but we care far more about what you've built than where you studied.
Outstanding Bachelor's and Master's graduates with exceptional research experience are also encouraged to apply. While this role is designed for candidates with significant research maturity, we frequently hire outstanding engineers into other technical positions.
Responsibilities In this work, you'll own the full arc from concept to prototype: modeling device physics, running simulation studies to de-risk design choices, and iterating alongside the hardware team as we test and refine. As we grow, this role has room to expand — but for now, it's about getting hands dirty and building the thing.
Design, model, and simulate MEMS-based microfluidic structures (FEM/Multiphysics simulation)
Support prototyping, testing, and iteration with the hardware team
Collaborate cross-functionally with biochemists and software engineers to align device performance with system requirements
Define and run validation protocols to benchmark simulated performance against physical prototype data
Identify failure modes and design trade-offs early through simulation, reducing costly iteration cycles on physical prototypes
Own the technical documentation of device physics and simulation models, ensuring the team can build on your work as it scales
Evaluate and select fabrication processes and materials suited to skin-contact applications
Contribute to IP and technical strategy discussions around the patch's core mechanisms
About you
You have designed and simulated MEMS devices. Not as a contributor on a large team. As the person responsible
You have hands-on expertise with Multiphysics simulation tools (COMSOL) and know how to validate a model against real prototype behavior, not just a clean simulation
You have a strong foundation in fluid dynamics, liquid/solid interfaces, and exposure to microfabrication processes
What we offer
Ownership from day one.
Swiss visa and work permit sponsorship for outstanding international candidates
Access to EPFL's world-class CMi cleanroom and research ecosystem
A fast-moving, highly collaborative team where decisions happen quickly
The resources, autonomy, and trust to do exceptional work
Clear opportunities to grow into technical leadership as the company scales
Be part of the molecular health revolution #J-18808-Ljbffr
