Staff Software Engineer

We are looking for a Staff Software Engineer to join the AppSec engineering team in Armis R&D.  The team builds Armis Centrix for Application Security, an AI-native AppSec product built from the ground up over the past year and now growing into a core product line. You get the best of both worlds: a small, autonomous team that owns its product end to end, backed by the data, expertise, and stability of Armis and ServiceNow engineering. If you love taking a product from its first customers to enterprise scale, own outcomes end to end, and raise the bar for the people around you, this is for you.  What You'll Do  • Own Your Area: Take complex, open-ended problems from design through production, hands-on in architecture, design, and the critical paths of the codebase, with the accountability that comes with it.  • Build Agentic AppSec: Design and build LLM-based agents and pipelines that analyze real-world codebases at scale: orchestration, tool use, context engineering, and the deterministic components that do what models shouldn't.  • Make AI Trustworthy: Practice evaluation-driven development: the evaluation harness, golden datasets, regression gates in CI, and cost and latency tracking, so every pipeline change is measured before it ships.  • Own the Backend & AI Architecture: Design robust, multi-tenant microservice cloud environments with security by design as the default.  • Deliver on Commitments: Design, estimate, and deliver your work as clear, estimated tasks you own end to end.  • Raise the Bar: Review designs and code, mentor engineers around you, and help set the team's engineering standards.  • Engage Beyond the Code: Work directly with product, customers, support, and R&D architecture to gather real-world insight, unblock fast, and align technical direction with the business.  • Collaborate Globally: Work closely with engineers and stakeholders across Israel, North America, and India.    • 5+ years of deep backend/systems experience, strong Python, and real production experience in a multi-tenant microservice cloud environment.  • Strong advantage: hands-on experience building LLM-based agents or agentic pipelines in production, and evaluating them: golden datasets, benchmark, regression gates, cost and latency at scale.  • A track record of owning outcomes end to end, including a commitment that went wrong and what you did about it.  • A security engineering mindset: tenant isolation, access control, and secure design are non-negotiable to you.  •  An All-Around Player: independent, execution-focused, and happy to build whatever it takes.     Excellent English for working effectively across time zones.  Work Personas We approach our distributed world of work with flexibility and trust.
