Associate Security Engineer

At Spendesk, we're building the leading spend management platform for modern businesses, processing billions of euros across Europe and beyond. Security is at the heart of what we do: our customers trust us to safeguard their financial data, and we're committed to raising the bar for security in fintech.

You'll be hands-on across vulnerability management, access controls, monitoring, and secure development support. You'll work closely with a Senior Security Engineer who'll mentor you and help you grow, while partnering day-to-day with Infrastructure and product engineering teams.

• Triage vulnerabilities from our bug bounty program, scanners, and dependency checks.
• Support incident response: develop fixes, track resolution, update tickets, and contribute to post-mortems.
• Monitor and process security alerts from our SIEM and other monitoring tools.

• Implement and maintain SSO/MFA configurations for product and infrastructure systems, leveraging Okta and Google Workspace to manage downstream access rights.
• Implement roles and access rights per tool and system.
• Run periodic permission reviews and access audits.
• Manage production secrets and credential rotation.

• Run pre-deployment security checks: static analysis, dependency scanning, container image scanning.
• Flag issues in code reviews when security patterns are violated.
• Help engineers understand and fix security findings.
• Assess adoption of AI coding tools across engineering teams: flag insecure usage patterns, identify data leakage risks, and help maintain internal AI usage guidelines.

• Monitor SIEM alerts, investigate suspicious activity, and elevate when needed.
• Maintain and tune detection rules under guidance from the Senior Security Engineer.
• Help operate and maintain SIEM infrastructure (Elastic Search, log collection pipelines).

• Support pentest coordination: prepare test environments, track remediation items.
• Maintain documentation on security procedures and runbooks.

• Foundational experience in security engineering, SOC, or a Dev Ops/SRE role with a strong security focus, eager to deepen across the security stack.
• Solid understanding of web application security (OWASP Top 10, common attack vectors).
• Hands-on experience with at least two of: vulnerability scanning tools, SIEM/log analysis, IAM systems (Okta, Google Workspace), or CI/CD security tooling.
• Comfortable scripting (Python, Bash, or similar) to automate repetitive security tasks.
• Collaborative mindset: you work across many teams and communicate security issues clearly and constructively. Rather than binary allowed/forbidden calls, you assess and articulate risk through a severity and likelihood lens, bringing teams along instead of acting as a blocker.

• Experience with AWS security (IAM policies, Security Hub, Guard Duty).
• Familiarity with Elastic Search / ELK stack.
• Exposure to infrastructure-as-code (Terraform) and container security.
• Knowledge of compliance frameworks (ISO 27001, SOC 2, PCI-DSS): not as an auditor, but enough to understand why controls exist.
• Experience in fintech or a regulated environment.
