Questions about this listing
What salary does ReleWant offer for this role?
ReleWant lists CHF 72'000 - 97'000 gross per year for this position in Chiasso. This is the salary published in the original listing — the calculator on this site converts it to your actual net take-home once cross-border tax and social contributions are applied.
Is this a full-time role, and what type of contract does ReleWant offer?
This listing is a full-time position. The contract type shown here comes directly from the employer's original posting; always confirm exact hours, notice period and probation length with ReleWant during the application process, since these details can vary by role even within the same contract category.
Do I need the G permit to apply for this role in Ticino as an Italian cross-border worker?
Yes. For EU/EFTA citizens the G permit no longer depends on a border zone: you need residence in an EU/EFTA state, a Swiss contract and a return home at least once a week. The 20 km band matters for taxation, not for the permit. The Swiss employer files the G-permit application at the Ticino cantonal migration office after the contract is signed — first issuance takes 2-6 weeks. The permit lasts five years with an open-ended contract or one over a year, otherwise for the length of the contract.
How do I apply for this position at ReleWant?
Use the "Apply now" button on this page — it links directly to ReleWant's original listing at relewant.zohorecruit.com, so your application goes straight to the employer's own applicant-tracking system. Frontaliere Ticino does not collect or forward applications itself.
