The successful candidate will play a crucial role in supporting the implementation of a browser isolation solution, specifically focusing on Menlo Security’s products, with primary emphasis on web integration, browser behaviour, and application compatibility. This role requires strong web fundamentals, structured troubleshooting capability, and the ability to partner effectively with security and networking teams to ensure seamless integration and optimal performance.
