## Job description

Talon.One, an Adyen company, is the most powerful incentives engine that unifies loyalty, personalized promotions and offer management into a single platform.
Built for enterprise scale and security, Talon.One helps businesses design and deliver incentives that drive real customer behavior.

Today, over 300 of the world’s most-loved brands including Sephora, Gymshark and Costa Coffee work with Talon.One to turn their incentives into a reliable growth engine.

**ABOUT THE ROLE:**

You'll be one of Talon.One's first two security engineering hires, owning the security of everything we ship to our customers and third-party partners, from API authorization to the AI features going into our platform and their real-time observability and detections. You'll work hands-on, pairing directly with engineers and product managers rather than filing tickets, across a multi-tenant platform that powers promotions and loyalty for some of Europe's largest retail and travel brands. Based in Berlin, hybrid.

**ONCE YOU ARE HERE YOU WILL:**

- Threat-model new product features before they're built, including AI-embedded ones, and turn what you find into real engineering work
- Own tenant isolation and API security across our Rule Engine, Integration API, Management API, CAMA, UCP Predict features, Talon.One MCP and third-party integrations
- Act as the security design authority for our AI features, working closely with the team behind UCP and Predict
- Build automated cross-tenant and adversarial testing that runs in CI, so isolation gets checked on every build, not only during our external yearly Pentest iterations
- Build standard, frictionless and automated golden paths for code security checks in CI workflows that developers can adopt by default without slowing down delivery
- Run vulnerability and coordinate efficient patch response across every squad outside Platform, from automated dependency updates to drilled emergency response
- Build and own application and AI security monitoring with our observability tools and build real-time security detection rules and alerts, and security events runbooks
- Design the security of the API integration between Talon.One and Adyen as our products come together
- Run a security champions programme so all our tribes build real security capability, not just the security team
- Experiment with AI, leverage innovative ways and build new workflows to identify, prioritize, and remediate product security risks at scale.

**WHAT WE NEED YOU TO BRING TO THE TABLE:**

- Experience with shipping production code, whether you come from software engineering or from security work that includes coding
- Experience with a multi-tenant SaaS platform's authorization and tenant isolation model, and strong knowledge of how to test for broken object-level authorization automatically
- Design API security end-to-end: authentication, credential lifecycle, rate limiting, abuse resistance and webhook security
- Hands-on experience with threat-modelling methodologies such as STRIDE, translating identified threats into actionable engineering requirements and security tests
- Practical experience implementing and tuning SAST and DAST tools in CI/CD workflows, with a focus on useful developer feedback and effective vulnerability remediation
- Understanding how AI features actually get built, retrieval, context assembly, tool calling, agent loops, and know where indirect prompt injection breaks multi-tenant isolation
- Hands-on experience with Google Cloud security, Kubernetes, and tools like Wiz and Datadog
- Know how to build security monitoring and detections in-house tools (SIEM) yourself, from designing the signal through tuning it and writing the runbook
- Strong knowledge of OWASP security guidance, including the OWASP Top 10, API Security Top 10, and Top 10 for Large Language Model Applications
- Ability to influence engineers who don't report to you, and feel comfortable being early in a function with no existing playbook

**WHAT'S IN IT FOR YOU:**

- A product & engineering team, now part of Adyen, building the incentives engine behind some of the world’s biggest brands
- Adyen+, a significant monthly allowance to spend on whatever matters most to you and your wellbeing
- 28 days of paid annual leave
- €115 monthly commuting allowance when you join us in the office 3 days per week
- 25% employer contribution to your pension
- Annual all-company gathering at Adyen’s headquarters in Amsterdam, plus regional team events throughout the year
- Opportunity to connect in person at Adyen offices across 29 locations worldwide
