Our partner is looking for a Security Engineer based in Spain.

This is a hands-on product security role at the heart of a fast-scaling payments infrastructure environment. You will help design, review, and continuously improve the security posture of systems processing payments at general scale. The role combines deep technical execution with strategic influence, as you work closely with engineering teams building cloud, infrastructure, and product capabilities. You will be responsible for identifying risks early, shaping secure architecture decisions, and ensuring security is embedded throughout the development lifecycle. This is a unique opportunity to join a growing security function early and help define its long-term structure, tooling, and standards.

Conduct security reviews and threat modeling across product features and system designs, translating findings into clear, actionable recommendations for engineering teams.

Take ownership of end-to-end security initiatives, from initial design and planning through implementation and rollout.

Build and maintain internal security tooling and automation to streamline reviews, detection, and remediation workflows.

Coordinate penetration testing activities and ensure timely tracking and resolution of identified vulnerabilities.

Contribute to the broader Application Security roadmap, including initiatives in cloud security, supply chain security, AI-related risks, and ASPM.

Engage in proactive security research and incident investigation to continuously improve system resilience.

Partner closely with Cloud, Infrastructure,



and Engineering teams to embed security into daily development practices.

Proven experience in product or application security, including conducting threat modeling and security reviews in production environments.

Strong ability to read and write code, with a hands-on mindset for building security tools and automation rather than only reviewing findings.

Experience delivering security projects independently while aligning with broader technical direction and collaborating with senior engineers when needed.

Strong communication skills, particularly in translating security concepts to non-security engineering teams.

Familiarity with cloud, distributed systems, or modern software architectures is highly beneficial.

Experience in fintech, payments, or other regulated, high-security domains.

Interest in advanced security areas such as supply chain security, detection engineering, or AI-related security challenges.
