Senior Engineering Manager - Security Engineering

Title: Senior Engineering Manager - Security Engineering Location: New York Office; Seattle Office

We are looking for a seasoned Engineering Manager to lead Aircall's Security Engineering organisation. This is a high-impact leadership role spanning four pillars: Product Security, Infrastructure Security, Detection & Response, and Governance, Risk & Compliance (GRC). You will grow an established team of security engineers, set the technical direction, and partner closely with Engineering, Product, Legal, IT and Finance to embed security deeply across the company. You’ll scale the team through high impact AI engineering across all 4 pillars.

You will be both a skilled people manager and a credible technical leader — someone who can roll up their sleeves when needed but who ultimately scales their impact through their team. You bring empathy, clear communication, and a bias for pragmatic security outcomes over security theatre.

Scope of Responsibility:

• Own the Secure Software Development Lifecycle (SSDLC) from threat modelling through to production deployment.
  Secure Agentic development practices by automating threat modeling, code reviews, internal pentesting and vulnerability remediation by building in-house security AI agents.
• Partner with engineering to embed security reviews, static analysis (SAST), dependency scanning (SCA), and secrets detection into CI/CD pipelines.
• Lead the Aircall Bug Bounty and Vulnerability Disclosure Program (VDP), triaging and remediating reports with engineering teams.
• Drive regular penetration testing cycles for web, mobile, and API surfaces; oversee remediation tracking.
• Champion a developer-centric security culture through security champions, training, and tooling that makes the secure path the easy path.

Infrastructure Security

• Define and maintain the security architecture of Aircall's cloud infrastructure (AWS), with a strong emphasis on zero-trust, least privilege, and defence in depth.
• Own, maintain and expand security observability through CSPM, CNAPP and CWPP tools like Wiz.
• Enable agentic auto-remediations for security vulnerabilities.
• Own network segmentation, secrets management, certificate lifecycle, identity & access management (IAM), and workload isolation, and secure hosting of internal AI applications
• Lead infrastructure hardening programs: CIS benchmarks, container security, Kubernetes policy enforcement (OPA), and immutable infrastructure practices.
• Manage the security posture of third-party SaaS tools and vendor risk assessments.
• Collaborate with Infrastructure engineering and Product Engineering on shared security responsibilities and runbooks.

Detection & Response

• Build and mature Aircall's threat detection capability — SIEM tuning, alert triage playbooks, and investigation workflows.
  Own incident response: develop and test the IR plan, lead tabletop exercises, and act as incident commander for significant security events.
• Drive threat intelligence and threat hunting programs to stay ahead of adversaries targeting the cloud communications sector.
• Establish and track key security metrics: MTTD, MTTR, alert-to-incident conversion rates, and coverage gaps.
• Ensure 24×7 detection coverage through tooling, automation, and on-call rotations, balancing reliability and engineer wellbeing.

• Own and continuously improve Aircall's information security management program, aligned to SOC 2 Type II, and applicable data-protection regulations (GDPR, CCPA).
• Lead audit preparation and evidence collection for external certifications and customer security questionnaires.
• Maintain the corporate risk register for information security, presenting findings and remediation plans to senior leadership and the board as required.
• Define and enforce security policies, standards, and exception processes across the organisation.
• Act as the primary security liaison for enterprise customers, prospects, and partners conducting security due diligence.

People Leadership

• Lead, mentor, and grow a multi-disciplinary security team of 6–10 engineers across the four pillars.
• Run structured 1:1s, career-development conversations, and quarterly goal-setting aligned to company OKRs.
• Hire and onboard exceptional security talent; contribute to employer-branding initiatives in the security community.
• Create an environment where engineers feel psychologically safe to raise concerns, experiment, and learn from failures.
• Balance hands-on technical involvement with delegation — staying close enough to the work to be credible, but trusting the team to execute.
• Partner cross-functionally with Engineering leadership, Legal, People Ops, and Finance to align security initiatives with business priorities.

What We're Looking For:

• 7+ years of professional experience in security engineering.
• 3+ years in an engineering management or technical lead role with direct reports.
• Proven track record of building and scaling security teams in a cloud-native, SaaS environment.
• Deep technical fluency across at least two of the four pillars (Product Security, Infrastructure Security, D&R, GRC).
• Hands-on experience with major cloud platforms (AWS strongly preferred, GCP or Azure a plus) and infrastructure-as-code (Terraform, CDK, or equivalent).
• Experience owning or contributing to SOC 2 Type II, ISO 27001, or equivalent compliance programmes.
• Demonstrated ability to communicate security risk clearly to non-technical executives and board members.
• Experience running security incident response — from detection through containment, eradication, and post-mortem.

Preferred / Nice to Have:

• Background in a high-growth B2B SaaS or cloud-communications company.
• Familiarity with VoIP, real-time communications, or telephony security considerations.
• Experience embedding Agentic AI practices into security engineering workflows and securing internal AI tooling and implementation.
• Relevant certifications: CISSP, CISM, AWS Security Specialty, GIAC (GWAPT, GCIA, GCIH), or equivalent.
• Experience running a Bug Bounty programme (HackerOne, Bugcrowd, or similar).
• Contributions to the open-source security community, conference speaking, or published research.
• Familiarity with DORA metrics and the relationship between deployment frequency and security posture.
