Big banks were slow, their products weren't fit for purpose, and small business owners often couldn't access what they needed. We set out to fix that.\nToday we're a financial platform - not just a credit card company. We offer a best-in-class business credit card, SME-focused spend management platform, a savings product that hit £1 billion in funds within its first year, and a growing suite of tools and financial products that make running a small business easier. \n1,000+ employees, £20bn in annual card spend, 200,000+ customers, 17,000+ Trustpilot reviews averaging 4.7 stars, and we're profitable. We’ve done a pretty good job so far, but we’re just getting started! \nThis is a Hybrid role, the Engineering team work from our London (Moorgate) Offices 2 days per week.\nThis is a multiple headcount role, so please don't be put off if you've seen this advertised for a while.\nThe role\nStaff Engineers take on technical problems that no single engineering group can solve on its own.

Familiarity with web or mobile frameworks would also be beneficial but not required.\nExceptional communication and collaboration skills with engineers and non-technical people alike.\nDemonstrable ability (and comfort) to influence people who don't report to you.\nNice to have: fintech or regulated financial services experience, and experience using AI tools to make engineering teams better.\nDiversity & Inclusion \nWe welcome, consider and encourage applications from anyone who shares our commitment to inclusivity. Join us in creating a space where authenticity thrives, and everyone can do their best work.\nGreat Work Deserves Great Perks\nWe try not to take ourselves too seriously (all the time) so we make sure our office is decked out with a pool table, arcade machine, beer tap, and a couple of office dogs thrown in for good measure.
