• You're collaborative and pragmatic with great communication skills, with the ability to explain technical decisions to both engineering and business stakeholders
• A background in payments, FX or another regulated industry would be of benefit

What's in it for you:

• Salary to £95k + bonus
• 23 days holiday, rising to 28 + your birthday off
