Location: London / Hybrid — very occasional travel into the office, with flexibility to attend when required
Contract: 6 months (Inside IR35)
Rate: £650/day
I'm working with a confidential client in the Financial Services sector to find an experienced Security Consultant to join their team on a 6-month contract.
The Role
This is a trusted-advisor role sitting across Product, Engineering and Architecture, embedding secure-by-design principles into delivery without slowing teams down. You'll lead secure design reviews and threat modelling for key solutions, provide clear and actionable security guidance, and apply CIS-aligned security NFRs and patterns across cloud, identity and application security — all within a structured governance lifecycle aligned to Design Authority and CAB.
