Lead, Application Security

About the Role
We're building a new UAE-based business spanning Sportsbook, Casino, Lottery, and a broader connected Fan Ecosystem, backed by the company and Momentum. As Lead, Application Security, you'll own application security testing and DevSecOps engineering end to end across the company's technology platforms.
This is a hands-on engineering leadership role. You'll be responsible for embedding security throughout the software development lifecycle, ensuring our applications, APIs, infrastructure, and deployment pipelines are secure by default. You'll own the application security tooling ecosystem, engineer automated security controls into CI/CD pipelines, and build the guardrails and developer self-service capabilities that enable engineering teams to deliver securely at pace.
With AI increasingly changing how software is built, you'll also play a key role in making AI-assisted development secure by design. This means understanding the risks introduced by AI-generated code and agentic workflows, implementing practical security controls, and helping developers use AI coding assistants safely and effectively.
The ideal candidate combines strong software engineering fundamentals with an offensive security mindset. You're comfortable getting hands-on with code, validating vulnerabilities, automating security controls, and influencing engineering teams. You know how to distinguish theoretical findings from genuine, exploitable risk and turn those insights into practical improvements.

Responsibilities
Application Security & Testing

• Own the company's application security testing capability across SAST, DAST, IAST, SCA, secrets detection, container scanning, infrastructure-as-code scanning, API security, and mobile application testing.
• Manage the full lifecycle of application security platforms, including evaluation, implementation, integration, configuration, upgrades, and ongoing optimization.
• Establish application onboarding, scanning policies, security rules, and testing frequency based on application risk.
• Tune existing rulesets and develop custom rules to improve accuracy and reduce false positives.
• Build a consolidated view of application security risk, prioritizing findings based on exploitability and business impact.
• Extend application security testing to AI-generated code and AI-enabled product features.

Vulnerability Management & Developer Enablement

• Own vulnerability triage, validation, prioritization, and remediation tracking across application security findings.
• Establish automated workflows to route findings to engineering teams, track remediation against agreed SLAs, and verify closure.
• Build developer self-service capabilities, including IDE integrations, secure templates, approved base images, and hardened libraries.
• Provide practical, actionable remediation guidance directly to developers.
• Establish and support a security champions network across engineering teams.
• Develop secure-by-default instructions, reusable rules, and skills for AI coding assistants to ensure generated code aligns with organizational security standards.
• Deliver targeted secure-coding education based on recurring vulnerabilities and root-cause analysis.

Offensive-Informed Application Security

• Validate high and critical vulnerabilities through hands-on testing and proof-of-concept exploitation in non-production environments.
• Conduct manual security testing of high-risk features, APIs, and business logic ahead of release.
• Translate confirmed exploits and penetration-testing findings into automated regression tests.
• Design abuse-case testing for gaming-specific risks, including bonus and promotion abuse, wallet and balance race conditions, bet manipulation, account takeover, and responsible-gaming control bypasses.

Software Supply Chain Security

• Define and implement security controls for dependency management, artifact signing, provenance verification, and Software Bill of Materials (SBOM) generation.
• Assess third-party libraries, components, and build dependencies for security risk.
• Address AI-specific supply chain risks, including AI-suggested or non-existent packages, third-party models, MCP servers, plugins, and IDE extensions.
• Monitor newly disclosed vulnerabilities in third-party components and drive prioritized remediation across affected applications.

Threat Modeling & Secure Software Delivery

• Establish repeatable threat-modeling practices for application changes, scaled according to risk.
• Translate product security requirements into practical acceptance criteria, user stories, and test cases.
• Embed security evidence generation into CI/CD pipelines to support regulated platforms, releases, audits, and certifications.
• Threat-model AI-enabled features and agentic workflows, including risks such as prompt injection, sensitive-data exposure, and excessive agency.
• Partner with regulatory compliance and security teams to ensure application security evidence supports relevant regulatory and certification requirements.

Security Automation, AI & Continuous Improvement

• Build and maintain security automation and internal tooling where commercial solutions don't meet business requirements.
• Apply engineering best practices to security tooling, including version control, peer review, testing, and documentation.
• Implement guardrails for AI-assisted software development and test LLM-enabled product features against recognized security guidance, including the OWASP Top 10 for LLM Applications.
• Leverage approved AI capabilities for vulnerability triage, code analysis, and documentation, with appropriate human oversight.
• Establish performance reporting across application security, including testing coverage, pre-merge remediation rates, time to remediate, false-positive rates, and automation efficiency.
• Continuously improve the effectiveness, reliability, and adoption of security tooling across engineering.

Required Qualifications

• 8+ years of experience across software engineering, DevOps, or cybersecurity, including at least 4 years of hands-on application security delivery.
• Proven experience owning and operating enterprise application security platforms such as HCL AppScan, Checkmarx, Veracode, Snyk, Wiz Code, or GitHub Advanced Security.
• Strong hands-on experience across SAST, DAST, IAST, SCA, secrets detection, and container scanning, including configuration and tuning at scale.
• Experience integrating and operating security controls within CI/CD platforms such as GitHub Actions, GitLab CI, or Azure DevOps.
• Production-quality coding experience in at least one of Python, Go, Java/Kotlin, C#, or TypeScript.
• Deep understanding of the OWASP Top 10 and OWASP API Security Top 10, with the ability to identify, exploit, and remediate vulnerable code.
• Practical web and API security testing experience, including authentication and authorization vulnerabilities, injection, SSRF, deserialization, and race conditions.
• Experience using Burp Suite or equivalent application security testing tools.
• Hands-on experience securing AI-assisted development environments, including AI coding assistants and agents.
• Working knowledge of the OWASP Top 10 for LLM Applications and risks such as prompt injection.
• Familiarity with container security, Kubernetes deployment security, and infrastructure-as-code practices.
• Strong communication skills, with the ability to influence engineering teams and translate technical security risks into practical business recommendations.
• Demonstrated ability to take ownership, drive delivery, and balance security requirements with engineering velocity.

Preferred Qualifications

• Experience working in regulated industries such as gaming, payments, financial services, or other high-assurance environments.
• Knowledge of software supply chain security frameworks and tooling, including SLSA, Sigstore, CycloneDX, or SPDX.
• Experience securing real-time, high-transaction platforms and mobile applications.
• Experience establishing or managing a security champions program.
• Familiarity with AI security and governance frameworks such as MITRE ATLAS, NIST AI RMF, or ISO/IEC 42001.
• Experience building security tooling or automation using LLM APIs.
• Relevant degree or equivalent practical experience.
• Industry certifications such as OSWE, OSCP, GWAPT, or CSSLP. Demonstrable bug bounty contributions, CVEs, or published security research are particularly valued.
