Job description

The role is about:

We are looking for a Senior Product Security Engineer to strengthen and scale product security across our engineering organisation. Reporting to the Head of Information Security, you will embed security directly into the software development lifecycle — from architecture and design through build, deployment, and remediation — helping us launch secure products across card issuing, embedded finance / banking-as-a-service, and other payment solutions.

This is a hands‑on senior role with real ownership: you will introduce security gates into engineering workflows, select and operate the right application security tooling, improve CI/CD and software supply‑chain security, and use AI and automation to increase security coverage without slowing product delivery.

• Location: Limassol, Cyprus
• Reporting to: Head of Information Security

What you will do:

• Design and introduce security gates into the development lifecycle, including security requirements at design stage
• Lead threat modelling for new products and major changes
• Introduce security review practices into the pull‑request flow
• Provide secure‑by‑design input for new product builds across card issuing, embedded finance / banking‑as‑a‑service, and other payment products
• Select, deploy, and operate application security tooling across static analysis (SAST), software composition analysis (SCA), secrets detection, and dynamic testing (DAST)
• Decide pragmatically where traditional tooling is the right fit and where AI‑assisted alternatives provide better coverage or efficiency
• Build AI‑assisted secure code review and finding triage into the engineering workflow
• Own CI/CD pipeline and software supply‑chain security controls across engineering teams
• Implement and improve container image scanning, dependency management, software bill of materials, and security checks on infrastructure‑as‑code and deployment manifests
• Help ensure secure release practices are embedded in the way software is built and deployed
• Operate and maintain the group’s Product Security Requirements as a living standard applied to real launches
• Drive remediation of application‑layer findings with engineering teams, including findings from penetration tests, scanners, and disclosure reports
• Define realistic SLAs, track remediation ageing, and provide honest reporting
• Build product security awareness and capability across engineering through training, design reviews, and security champions initiatives
• Apply AI and automation to day‑to‑day product security work, including code review support, finding triage, and workflow acceleration
• Help extend security review coverage across multiple engineering teams without introducing unnecessary friction

What we need:

• 5+ years of experience in Product Security, Application Security, Security Engineering, or a closely related software security role
• Strong hands‑on experience embedding security into the software development lifecycle
• Proven experience with threat modelling, secure‑by‑design reviews, and working with engineers during architecture and delivery stages
• Hands‑on experience with application security tooling such as SAST, SCA, secrets detection, and DAST
• Experience securing CI/CD pipelines and improving software supply‑chain security
• Ability to work directly with engineering teams and influence secure delivery in practice, not just through policy
• Strong ownership mindset — able to define, implement, improve, and drive adoption of security practices across multiple teams
• Strong written and verbal English

Nice to have:

• Experience in payments, fintech, banking, e‑money, or another regulated product environment
• Experience supporting new product launches in cloud‑native or API‑driven environments
• Familiarity with container security, Kubernetes security, and infrastructure‑as‑code security
• Experience with AI‑assisted security workflows or automation in AppSec / Product Security
• Detection‑as‑code or security‑as‑code mindset
• Certifications such as CISSP, CSSLP, CCSP, OSCP, or similar
