Senior Software Engineer, Endpoint Agent

About the role

You own the complete lifecycle for desktop security software, designing and shipping agent capabilities that sit inside customer operating systems. This role demands low level systems thinking for high impact products. You solve demanding OS challenges inside a fast moving security environment. You will set the architectural direction for core agent modules, ensuring that every line of code aligns with the broader security strategy. You will partner closely with research and product teams to turn high level requirements into robust, production grade desktop components. The work requires you to balance performance, stability, and security while moving quickly in a startup setting. You will be responsible for validating agent reliability under diverse conditions before customer rollout.
