They are seeking a Senior Software Engineer to own end-to-end product development for AI-powered security products across the stack, emphasizing high agency and autonomy in a fast-paced environment.

Responsibilities:

• Own end-to-end product development  — from idea, research, and architecture to production
• Build and ship AI-powered security products  across frontend, backend, and APIs
• Develop scalable, high-quality interfaces and systems  that power real user workflows
• Work with minimal specs — define problems, make decisions, and execute independently
• Collaborate when needed, but primarily operate with lean ownership and high autonomy
• Drive adoption and impact  — iterate based on real usage, not just requirements
• Leverage LLMs and AI tooling  to accelerate development and improve team productivity
• Continuously improve systems, code quality, and developer workflows
