Intaso are partnering with a high-growth Fintech that is currently reforming its Security function as an enabler to the business. Under the guidance of a newly appointed, progressive Director of Information Security, the business is shifting away from traditional gatekeeper security toward a modern, platform-led model. We’re looking for a Security Engineering Lead to act as the primary architect and builder of this new chapter. You will be joining at the exact moment where you can have the most influence. The leadership is already aligned on a Security as Code vision, they just need the Lead to design the roadmap and execute it. You will have the budget to hire, the mandate to change processes, and the support of a CISO who values systems thinking over business.

The Challenge: Pragmatic Security at Scale

The mission is simple but difficult: bring structure, consistency, and scale to security engineering without compromising the velocity of the product teams. You will be responsible for:

  • Establishing the Function: Formalising a secure SDLC that fits a high-velocity CI/CD environment
  • Team Leadership: Managing and mentoring a team of 4+ engineers, fostering a culture of collective accountability and continuous growth
  • Engineering Partnership: Working as a peer to Engineering Leads to embed security guardrails (automated checks, IaC standards, and self-service tools) into the daily developer workflow
  • Modernising the Stack: Leading the security strategy across a cloud-native environment (AWS, Kubernetes, and Terraform), moving away from manual reviews toward Policy as Code

Your Profile

This role is designed for a technical leader who is tired of corporate bureaucracy and wants the autonomy to build an agile, proactive security function.

Experience: 8+ years in Security Engineering, with at least 3 years in a formal leadership or management role

Technical Breadth: Deep hands-on experience in AWS security, containerisation (Kubernetes), and CI/CD security integration

Mindset: You are a ‘Builder’. You prefer simple, automated solutions over complex, manual processes. You understand that security must be a business enabler

Sector Background: Experience in regulated environments (Fintech, Payments, or FS) is highly preferred, but a scaleup mindset is mandatory

This is an opportunity to take an existing small squad of engineers and shape them into a high-impact, automated security function that supports a fast-moving engineering culture.
