Senior Security Architect

Role Overview

The Senior Security Architect will be accountable for the security of the cloud infrastructure behind those services: reporting to the CTO, he/she sets the technical direction for cloud security across our AWS estate and define the standard that engineering teams build to. This is a hands-on senior role, positioned close to the platform and influential rather than supervisory.

• Design and own security controls across our AWS estate: IAM, network segmentation, encryption, logging, and secrets management.
• Lead threat modelling and security architecture reviews for new services and major changes, working one-to-one with development teams on secure design.
• Set cloud security policy and the security roadmap jointly with security and platform leadership.
• Partner with Product Management to define and clarify security requirements.

• Build security into CI/CD:
  IaC scanning, container and base-image scanning, dependency and SBOM checks, policy-as-code, and automated guardrails.
• Write and maintain Terraform modules and golden patterns so that the secure path is the easy path for product engineers.
• Drive adoption of automated security tooling, including cloud-native vulnerability scanning and security agents (e.g. AWS Inspector).
• Evaluate and recommend secure development tooling, including IDE-integrated security and AI coding-assistant guardrails.

• Improve detection coverage for cloud-native attack paths.
• Act as senior responder for cloud security incidents: build and maintain runbooks, and run post-incident reviews that produce durable fixes.
• Assess the impact of vulnerabilities and exploits, and own the incident response process end to end.

• Manage CSPM/CNAPP tooling: triage findings and drive remediation with the owning teams.
• Analyze the impact of WAF rules on our products.
• Coordinate DAST and penetration testing programs across products.

• Support ISO 27001 with evidence and control implementation.
• Support regulatory security obligations, including the EU Cyber Resilience Act (CRA).
• Lead security reviews of new third-party tools.
• Mentor engineers on secure cloud design and act as security partner to the platform, product, and operations teams.

• 8+ years in security engineering, including at least 5 focused on cloud.
• Deep, practical expertise with the AWS security suite:
  Organizations and SCPs, KMS, Config, Guard Duty, Cloud Trail, Security Hub, Inspector, WAF, and Shield Advanced.
• Strong infrastructure-as-code skills (Terraform) and scripting and automation (Python, Go).
• Kubernetes and container security experience.
• Working knowledge of identity protocols (OIDC, OAuth 2.0, SAML) and of applied cryptography and PKI: key hierarchies, certificate lifecycle, and secure key storage.
• Experience with secure SDLC practices: threat modeling, secure design review, SAST/DAST, and penetration testing.
• Experience leading incident response.
• Strong communication skills: you can influence engineering teams you do not manage and explain risk to non-security stakeholders in terms of business impact.

• Certifications such as AWS Certified Security
  - Specialty, AWS Certified Advanced Networking
  - Specialty, AWS Certified Solutions Architect
  - Professional, CISSP, or CCSP.
• Experience with media security, DRM, conditional access, or anti-piracy technologies.
• Knowledge of the EU Cyber Resilience Act and related product security regulations.
• Experience with HSMs and cryptographic key management.
• Familiarity with on-premises and cloud security tooling supporting the SDLC.
