Questions about this listing
What salary does Butterfly Trading Company SA offer for this role?
The original listing does not state a salary. Our estimate for this role and sector in Lugano is CHF 58'000 - 88'000 gross per year — an estimate, not a figure communicated by Butterfly Trading Company SA. The calculator on this site converts a gross salary into 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 Butterfly Trading Company SA 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 Butterfly Trading Company SA 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 Butterfly Trading Company SA?
Use the "Apply now" button on this page — it links directly to Butterfly Trading Company SA's original listing at job-room.ch, so your application goes straight to the employer's own applicant-tracking system. Frontaliere Ticino does not collect or forward applications itself.
