Application Security Engineering Manager

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for an Application Security Engineering Manager based in Ireland.

This role offers the opportunity to lead a highly skilled Application Security team at the forefront of securing AI-driven software development. You will shape how security is embedded across a rapidly scaling engineering organisation, ensuring secure by design principles are applied throughout the SDLC. Acting as both a technical leader and strategic enabler, you will guide senior engineers working on advanced AppSec challenges such as threat modelling, AI assisted development security, and automated security tooling. The environment is highly collaborative and deeply technical, with strong emphasis on autonomy, trust, and impact. You will work closely with engineering, platform, and leadership teams to define scalable security practices that evolve alongside cutting edge AI products. This is a high impact leadership role where your decisions directly influence product security, engineering velocity, and organisational resilience.

Accountabilities

• Lead, grow, and support a senior Application Security team, including hiring, onboarding, performance management, and career development.
• Enable a highly autonomous team of senior engineers by creating the right environment, structure, and operating rhythm for success.
• Define and evolve the Application Security strategy and roadmap, translating risk, engineering input, and business priorities into clear initiatives.
• Act as a hands on technical partner in areas such as threat modelling, secure architecture design, and application risk analysis.
• Establish and maintain team planning processes, including OKRs, quarterly planning, and cross functional coordination.
• Serve as the primary interface between AppSec and broader engineering, platform, legal, and leadership stakeholders.
• Drive integration of security into AI assisted development workflows, including assessment of agentic coding tools and AI generated code risks.
• Oversee AppSec alignment with broader security functions, ensuring consistent handling of incidents, risks, and cross team initiatives.
• Represent the AppSec function in external contexts such as audits, compliance programmes (e.g., SOC2, ISO 42001), and customer engagements.
• Promote continuous improvement in AppSec tooling, automation, and security engineering practices.

Requirements

• Strong background in Application Security with hands on experience in threat modelling, secure design reviews, vulnerability management, and security automation.
• Proven experience as a Security Engineer who has progressed into engineering leadership or management roles.
• 3+ years of people management experience, including hiring, mentoring, and performance management of senior security engineers.
• Deep technical understanding of modern software development practices, secure SDLC, and cloud native architectures.
• Strong programming skills, particularly in Python and JavaScript.
• Experience with cloud platforms such as AWS and/or GCP, and familiarity with CI/CD tools such as GitHub Actions.
• Experience leading or significantly contributing to AppSec programmes in fast scaling SaaS or AI driven environments.
• Strong communication skills with the ability to engage across technical engineers, leadership, and cross functional stakeholders.
• Practical experience embedding security as a collaborative partner within engineering teams rather than a gatekeeping function.
• Strong understanding of AI native security challenges, including LLM based systems, agentic tools, and AI generated code risks.
• Familiarity with tools such as Semgrep, Wiz, CrowdStrike, HackerOne, or similar AppSec ecosystems is a plus.
• Kubernetes experience and prior Staff/Principal level security engineering background are considered strong advantages.

Benefits

• Flexible, remote friendly working model across Europe or selected hubs.
• 25 days of annual leave plus public holidays based on location.
• Work from home setup support.
• Generous referral bonus programme.
• Opportunity to work remotely from abroad for up to 60 days per year.
• High impact leadership role in a fast scaling AI driven engineering organisation.
• Significant autonomy and ownership in shaping the AppSec function and strategy.
• Strong career growth potential in a market defining AI company.
• Collaborative, high trust engineering culture focused on outcomes and simplicity.
• Opportunity to build and scale AI native security tooling and practices.
