About Zephyra

Zephyra (QTool S.r.l.) is a deep-tech innovative SME based in Pont-Saint-Martin, in the Aosta Valley, Italy. We build a Physical AI platform for autonomous and sustainable manufacturing. Our vision is to cut global emissions by 1% by 2050, the equivalent of planting more than half a billion trees every year.

We develop cutting-edge 3D modelling software and physics simulation techniques 1000 times faster than the state of the art. These tools drastically reduce industrial scrap and energy consumption. We work with leading companies in Italy and abroad. We are a small team that aims for excellence and ownership from day 0.

The job in one paragraph

Our platform is built for the manufacturing shop floor, making advanced tools accessible to machine operators and engineering teams: a user uploads a part and the technical needs, and the platform reads the tolerances, checks manufacturability, estimates the cost, and runs physical simulations such as cooling and warpage. You will own the numerical heart of that: the solvers (FEM, FVM), the mesher, and the optimisation framework that searches the whole manufacturing system — pressure, temperature, cooling time, structure — with one optimizer; your code runs for real customers within weeks.

What you will do

- Solvers. Develop thermal, flow and structural solvers (FEM, FVM) and validate them against reference cases and real production data.
- Meshing. Build the mesher that turns complex 3D geometry into solver-ready meshes automatically.
- Optimisation.



Build the framework that finds the best design and process settings: fast models to explore, full simulations to confirm.
- Code. C++ and Python (JAX), GPU where it pays; tests and reviews on every change.

What we look for

- Master's or PhD in computational mechanics, applied mathematics, mechanical/chemical engineering or physics; 0–3 years after the degree (a strong thesis counts).
- Numerical methods you have implemented yourself: FEM/FVM/VEM, time integration, nonlinear solvers; experience with at least one of OpenFOAM, CalculiX, lattice-Boltzmann codes, or your own solver.
- Heat transfer and fluid mechanics as working tools — non-Newtonian flow, conjugate heat transfer, phase change are a big plus.
- C++ you are not afraid of, and Python with NumPy/JAX; CUDA or MPI a plus.
- Optimisation: gradient-based methods, adjoints/autodiff, multidisciplinary design optimisation (MDO/MSDO).
- Meshing of implicit geometry (polytopal/VEM meshes) is a plus.
- Experience with Physics Informed Machine Learning is a strong plus.
- English as the working language; Italian a plus.

What you get

- A product where your solver's number is used on the shop floor the same week.




- The cluster and the GPUs you need; our own kernel and solvers to extend, not a vendor's black box.
- Hybrid work from the Aosta Valley office (1 h from Turin, close to Grenoble and Lausanne); relocation help for the right candidate.
- Full-time employee contract under the Italian CCNL ICT (CIFA–CONFSAL); apprenticeship contract for candidates under 30. Gross annual salary €20,000–50,000, depending on experience.
- A thesis-to-hire path: we also take master's/PhD theses on the optimisation framework.

How to apply

Apply here with your CV and add one thing you built — a solver, a mesher, an optimisation study, a repository (a link is enough). Three steps: a 30-minute call, a technical session on a real case, an offer. If you would need a work permit for Italy, say so in your application.
