About the Role
We are looking for a Security Engineer to lead the architecture and automation of our global security infrastructure. In this role, you will drive the strategy for endpoint and network defense across on-premises and multi-cloud environments (AWS, GCP, Azure), operating with high autonomy to solve complex, undefined security challenges. You will be responsible for building tailor‑made solutions and establishing the standards that protect a platform impacting millions of lives.
As a technical leader, you will bridge the gap between deep execution and organizational influence. You will lead cross‑functional initiatives, mentor engineering teams, and advise on long‑term security investments and roadmaps. We need a defensive security expert who combines strong technical reasoning with the ability to reduce complexity, guide technical debates, and deliver high‑scale results in a fast‑scaling, customer‑obsessed environment.
Responsibilities
Design, implement, and support multi‑country security solutions for on‑premises and cloud infrastructures (endpoint and network), including defining and developing automation to enable large‑scale deployments and operation;
Develop and maintain security policies and documentation for new endpoint and network technologies, contributing to high‑level documentation for non‑engineers and detailed technical documentation for engineering teams;
Ensure secure configuration and management of endpoints, network systems, and security applications using appropriate security platforms, tools, and operating‑system‑specific controls;
Support risk assessments related to endpoints, networks, and information protection, helping identify and mitigate security exposures;
Support security reviews and audits, assisting internal audit teams with endpoint and network security issues and compliance activities, and participating actively in discussions;
Support to respond to cyber threats, incidents, and anomalies affecting endpoints and networks, anticipating technical issues at the enterprise and platform level and making architectural and design decisions to prevent them;
Evaluate build‑vs‑buy alternatives under general direction, articulating trade‑offs between technical, analytical, and platform needs, efficiency vs. thoroughness, and the impact on technical debt.
Required Skills and Expertise
Strong understanding of operating systems (Windows, macOS, Linux) and core security protocols, including authentication, authorization, and cryptographic principles;
Knowledge of network technologies, including routing, switching, network security protocols, and cloud networking (AWS, GCP, Azure);
Knowledge of application‑layer technologies, business continuity, disaster recovery (DRP), and secure system design;
Experience with research, analysis, and data‑visualization tools, as well as identity and access management, security operations, and security analytics;
Experience with automation and programming languages (e.g., Python and Go), including the ability to develop scripts, tools, and system integrations.
Technical expertise with cloud and on‑premises infrastructures, including secure architecture, deployment, and operations;
Experience in major incident management and security incident response across endpoints, networks, and cloud environments;
Experience in listening and guiding technical debates to help reach a consensus;
Ability to conduct in‑depth analysis of computer networks and systems to identify vulnerabilities, misconfigurations, and security gaps;
Awareness of the latest attack techniques, threat actor behaviors, and methods used to compromise systems and networks;
Strong soft skills, including effective communication with technical and non‑technical stakeholders, the ability to guide technical debates, and fast, informed decision‑making during critical events.
