About this listing
Published on Lever under the board identifier Ciandt, which is the name the employer’s own job board carries. RoleSprint has not verified the company’s registered or trading name, so it is shown exactly as published rather than tidied up.
RoleSprint is not the employer and not a recruiter. Applications are made on the employer’s own site and never reach us; what RoleSprint does is help you decide whether a role is worth your time and prepare for it if it is.
Published 13 November 2026, last checked yesterday. A posting stops being advertised here 90 days after the employer published it, and one the employer takes down is marked closed rather than quietly removed.
