# Product & AI Security Engineer at Talon.One

- **Company:** Talon.One
- **Location:** Berlin, Germany
- **Posted:** 2026-08-21
- **Last confirmed live:** 2026-09-11
- **Apply:** https://www.talon.one/job-listing?gh_jid=4958357101

## Job description

## 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:

- 90+ team of engineers, product managers and product designers in Berlin
- Leaders with 8+ years of experience building our promotions engine
- €1,000 annual learning budget and free German language courses to boost your skills
- 30 days of annual leave, plus extra paid days for your birthday and moving day
- Home office setup budget, a monthly home office allowance
- Freedom to work from abroad for up to 90 days worldwide!
- Mental health support with nilo.health and a discounted Urban Sports Club membership
- 20% company subsidy on your pension contributions
- Subsidised BVG public transport ticket and a dog-friendly Berlin office where your furry friend is welcome
- Lease your ideal bike through BusinessBike

WHY YOU SHOULD WORK FOR US:

- The right attitude: modern methods and a diverse, creative workspace with an open and international culture
- Everyone for the product: Together we create a flexible, highly scalable product with state-of-the-art technologies. We can only succeed if everyone works as a team
- Healthy Growth: Growing our company means growing everyone in the team. We love to share knowledge and learn
- A great environment: Flexible and family-friendly environment, bright and easily accessible offices, modern software and hardware
- High flexibility degree: Prefer to work early or late at night? Do you have to pick up your children from kindergarten? Do you prefer working abroad? We believe in results and motivated employees
