Role
Who you are

- 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

- 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
What the job involves
- 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,…)
- 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
Our take
Call centres have been a mainstay of sales teams for decades, with the human touch delivering an impression conversion rate of about 30% for inbound calls. However analogue call centres are physical infrastructure-heavy and unable to take advantage of the flexibility afforded by remote and hybrid ways of work. Aircall exists to change that, providing a cloud-based call centre infrastructure that allows sales teams to work from their home offices.
Aircall isn't the only company in this space, and it faces heavy competition from Cloudtalk, another cloud-based call centre solution. However Aircall stands out in the market by its use of open APIs and webhooks, making integration with existing productivity and helpdesk tools much easier, and its superior call quality. Aircall has developed a significant customer base with these strengths, with over 15,000 companies using its platform.
The company has raised significant funding in recent years, highlighting the confidence investors have in their offering. With a rapidly expanding presence in the US, European, UK and Australian markets and recent refresher leadership hires, Aircall could soon be a widely recognised international player in the telephone software industry.
