Contract: 6 months (Inside IR35)

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.

Key Responsibilities

  • Act as a trusted security advisor to Product, Engineering and Architecture within a Financial Services environment
  • Embed secure-by-design principles across delivery
  • Lead secure design reviews and threat modelling (STRIDE preferred)
  • Provide clear, actionable security guidance aligned to delivery
  • Apply CIS-aligned security NFRs and patterns across cloud, identity and application security
  • Support teams implementing security within the SDLC
  • Align with Design Authority (DA) and CAB, delivering assurance and confirmation outcomes
  • Identify and drive remediation of security technical debt with clear ownership and timelines
  • Build strong stakeholder relationships through pragmatic, outcome-focused advice

What We’re Looking For

  • Proven background in Financial Services or another heavily regulated environment (essential)
  • An architecture-oriented profile — comfortable operating at a design/solution level, not just tactical delivery
  • Hands-on threat modelling experience, STRIDE preferred
  • Strong knowledge of Azure security, IAM, and application/API security
  • Experience embedding security within Agile delivery teams / SDLC
  • Comfortable working with Design Authority (DA) and CAB governance
  • Relevant certifications: CISSP, CISM, SC-100 or equivalent
