Arrindell worked as barrister in Georgetown and in 1824, he defended John Smith in his trial. Arrindell became Attorney-General of British Guiana in 1845 and was subsequently appointed Chief Justice of British Guiana in 1852. He was created a Knight Bachelor in 1858 and was made a Companion of the Order of the Bath in the same year. He died at Demerara, aged 66, from the consequences of a fall from a staircase. His funeral procession stretched for half a mile and was the greatest British Guiana had seen so far.
