Lead Game Security Engineer
We are seeking a Lead Game Security Engineer to strengthen the security of online game services, platforms, and development environments. In this role, you will define and deliver security strategies across the game lifecycle, from early design and development through launch and live operations. You will work closely with engineering, infrastructure, anti-cheat, trust and safety, QA, and production teams to identify risks, prioritise improvements, and embed secure practices into everyday development.
Your responsibilities will include leading threat modelling and security reviews for game clients, backend services, APIs, authentication systems, payment flows, and online infrastructure. You will design and oversee anti-cheat and anti-abuse controls, investigate vulnerabilities and suspicious activity, and coordinate incident response when security events occur. You will also guide penetration testing, code and architecture reviews, security monitoring, vulnerability management, and remediation programmes. A key part of the position will be developing practical security standards, automation, and tooling that protect players and services without compromising performance or the player experience.
The successful candidate will bring substantial experience in game security, application security, platform security, or a related technical field, together with a strong understanding of multiplayer architectures, client-server interactions, networking, authentication, and common attack techniques. Experience with anti-cheat technologies, fraud prevention, reverse engineering, cloud environments, secure software development, and incident response is highly desirable. You should be comfortable leading technical initiatives, mentoring engineers, communicating risk to both technical and non-technical stakeholders, and influencing decisions across multiple teams. Strong analytical skills, sound judgement, and a proactive approach to emerging threats are essential, as is the ability to balance robust protection with reliability, scalability, and an excellent player experience.
