Senior Application Security Specialist

Shape the future of security in a fast-scaling fintech environment.

A rapidly growing fintech company at the forefront of financial innovation is hiring its first Application Security Engineer. With increasing visibility in global markets and an evolving threat landscape, the company is investing in building security into the core of its technology platform.

This is a greenfield opportunity to establish foundational AppSec practices, influence engineering culture, and build security tools and processes that scale with growth.

What you’ll do:

• Embed security throughout the development lifecycle (SDLC)

• Lead code reviews, threat modeling, and secure design practices

• Develop and deploy automation for vulnerability detection and remediation

• Collaborate with engineering teams to ensure security is built in from day one

• Support incident response and post-mortem processes

What we’re looking for:

• Proven experience in application security, ideally in fast-moving or high-risk environments (e.g. fintech, SaaS, trading)

• Strong understanding of secure software design and common vulnerabilities

• Ability to write tooling or scripts (Python, Go, or similar) to support security automation

• Comfortable working cross-functionally with engineering, product, and infrastructure teams

• Bias for action, ownership, and solving real-world threats proactively

Location: Amsterdam 

Working Model: Hybrid (2 days/week in office)
