This role is only open to people authorized to work in the United States. Calendly does not sponsor visas at this time.
Anyone with a Calendly link can be booked, and that openness is also what attackers look for. The Trust and Safety team builds the systems that spot spam, phishing, bots and fraudulent text traffic before real customers feel it.
