We are looking for a Senior iOS Engineer who can step into an existing app, stabilise what's there, and deliver new AML-driven features fast. It is an immediate start contract role. This isn't a greenfield build. It's legacy code, regulatory deadlines, and zero margin for delay. What you'll be doing: ● Working within a legacy iOS codebase, understanding it quickly and improving stability ● Building out new screens and flows aligned to AML regulatory requirements ● Shipping production-ready Swift code under tight delivery timelines ● Collaborating with product and backend to meet compliance deadlines What actually matters: ● Strong Swift / native iOS experience in production environments ● Proven ability working in legacy or less-than-perfect codebases ● Experience delivering under regulatory or deadline-driven pressure (finance, banking = ideal) ● Ability to make pragmatic decisions — fix what matters, don't boil the ocean Reality check: ● This is not polished or greenfield ● You'll be dealing with existing constraints and technical debt ● Speed and impact matter more than perfection
