Defined Career Pathways
Each open role is scoped to a single country rather than being open worldwide, so the eligible location is whatever the posting names. There is no published company-wide list of countries you can be hired in, and openings have appeared in both Europe and the Americas, so the role you are applying to is the thing to check.
The company does not publish a required number of overlap hours, so there is no stated block of the day you have to be online with the rest of the team. The constraint is meeting-shaped instead: internal and client meetings sit in western European or Eastern American working hours, and because this is client-services work, some of that timing is set by the client rather than internally. Headquarters is in the Eastern Time Zone and each role is scoped to one country, so how much of your day those windows cover depends on where the role is based. Outside them you choose your own hours.
The careers page lists 20 working days of paid time off per year for the first three years, rising to 25 days after that, plus 5 days of paid sick leave and 10 national holidays of your own choosing.
Yes. NineTwoThree reimburses expenses for professional development courses and certifications, and the careers page describes constant learning through tools and mentorship as part of the job rather than a side benefit.
No. There are no salary bands, ranges, or pay-transparency statements on the careers page, so compensation is something you discuss directly during the hiring process. They do state the engagement model up front: payment runs through Deel for W2 employees, direct contractors and 1099 contracts.
