Atom bank is one of the most compelling places to work in UK fintech right now, and not just because of the four-day working week. Atom became profitable for the first time in 2024 and has grown its loan book by 29% to £5.3 billion, while being consistently rated the UK's highest-rated bank by its customers on Trustpilot. The four-day work week is real and established: in November 2021, Atom became the largest company and only bank in the UK to introduce the policy for all employees, genuinely reducing contracted hours from 37.5 to 34 per week with no salary cut, and job applications rose 49% as a result. There is also genuinely no mandatory office attendance, with only around 10% of staff regularly coming in. What really stands out is that Atom has done all of this from Newcastle, building one of the UK's best-loved banks without ever opening a London office. Glassdoor reviewers consistently highlight the brilliant people, the no-blame culture, and the interesting and meaningful work. The main caveat to note is that some employees, particularly at more senior levels, have reported limited progression opportunities as the company matures beyond its early startup phase. But if you want to work somewhere that backs its values with action, a genuinely flexible, people-first bank that is growing sustainably and has a product its customers genuinely love, Atom is hard to beat.
