Aircall

Senior Security Engineer - Remote EMEA

Job Description

As a Senior Security Engineer, you will be responsible for fostering and maintaining a good security posture on our infrastructure, application and processes to help other teams deliver customer value on top of Voice. Security testing best practices, evangelization, and mentoring in your team and across the whole of Engineering will be part of your day to day job.

Quality, excellence, and agility drive our delivery processes and you will help us level these up. Using modern tools (Rails, TS, Terraform, ...) on AWS, we build added value and resilient services on top of voice and fully integrate with our customers’ business critical tools (CRM, Helpdesk, E-Commerce,…).


Key Responsibilities:
  • Embed security early in the software development lifecycle by collaborating closely with engineering teams to integrate secure coding practices, automated security testing, and threat modeling.
  • Develop and implement security guardrails, ensuring developers and infrastructure teams can self-serve secure frameworks and best practices.
  • In charge of security reviews for new features, services, and infrastructure changes, proactively identifying and mitigating risks before deployment.
  • Design and implement AI-driven security solutions, leveraging machine learning for anomaly detection, threat intelligence, and automated response.
  • Develop automation to streamline vulnerability management, compliance reporting, and security operations.
  • Build and maintain security-as-code templates, playbooks, and CI/CD-integrated security controls, enabling developers to securely deploy software without friction.
  • Provide internal tooling and training that empowers teams to manage security risks without needing constant security team intervention.
  • Advocate for a DevSecOps culture by mentoring teams and driving security awareness across the engineering organization.
  • Harden Aircall’s SaaS infrastructure by designing scalable, cloud-native security solutions (AWS, Kubernetes, Terraform, etc.).
  • Strengthen API security and application security by enforcing best practices for authentication, authorization, and secure data handling.
  • Monitor and improve security observability, ensuring visibility across all environments through logs, alerts, and automated threat detection.
  • Own and improve incident detection and response capabilities, ensuring rapid containment and resolution of security threats.


    • Qualifications:
  • You have at least 5+ years of experience in Security involving Public Clouds ( preferably AWS)
  • Strong development background with experience in secure coding practices
  • Experience with automation & AI-driven security – ML-based threat detection, and security automation tools
  • Hands-on expertise in DevSecOps – integrating security tools into DevOps workflows (SAST, DAST, IaC scanning, runtime protection).
  • Shift-left & enablement-focused: Passion for making security a frictionless part of engineering workflows rather than a blocker.
  • Self-service mindset: Believes in building security guardrails and automation so developers can self-serve security solutions.
  • Problem-solver & automation-first thinker: Constantly looks for ways to remove manual work through scripting, AI, or process improvements.
  • Strong collaboration & communication skills: Able to partner with developers, SREs, and product teams to drive security adoption.
  • Security evangelist: Proactively educates teams on security risks and best practices through training, workshops, and internal documentation.
