Menlo Security is the leader in Browser Security for human and agentic workforces. Our mission is to enable humans and agents to connect, communicate, and collaborate securely, without compromise. The Menlo Browser Security Platform protects organizations from cyberattacks by stopping threats across the web, documents, and email before they reach the user. With Menlo Agent Runtime Security (MARS), that protection now extends to the AI agents working alongside every employee. Menlo Security is trusted by major global businesses, including Fortune 500 companies and government agencies, to protect their most valuable asset, their data, and is backed by top-tier investors. Summary Menlo Security is hiring a Senior Software Engineer to join our Threat Protection and ShadowAI team in the UK. This team ensures that users can safely browse the web through Menlo's secure cloud — protecting them from malicious sites (including those built or operated with AI) and securing access to authorised web applications. The services this team builds are core to Menlo's secure enterprise browser for both humans and AI agents, which puts you at the centre of one of the most active problems in enterprise security right now: how organisations gain visibility into and control over unsanctioned AI usage without blocking it entirely. The team applies AI in how it builds as well — code assistants, AI-assisted test generation, and LLM-supported log and incident analysis — so you will be using these tools alongside defending against their misuse.
