Software Engineer Jobs in Cardiff

Cardiff is the UK's fastest-growing fintech hub by per-capita measure, anchored by Admiral Group, ActiveQuote, Confused.com and the Wales Fintech Cluster. Welsh-language requirements are rare in the tech sector — most roles operate in English.

Software engineering is the largest single hiring category across UK and EU job boards, with London, Manchester, Berlin and Amsterdam leading demand. Roles span product, platform, infra and ML — the right title can be hard to spot from the listing alone, so KeyStep ranks every live opening against your actual skills rather than keyword-matching the title.
