Job Description

Senior Staff Software Engineer (AppSec), Tel Aviv 

We are looking for a Senior Staff Software Engineer to join the AppSec engineering team in Armis R&D and lead it from the inside. 

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 

Lead From the Code: Be a technical lead in the team, 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: Own 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. 

Run the Team's Rhythm: Drive planning, estimation, and delivery of commitments; turn designs into clear, estimated work that engineers own. 

Grow People: Mentor, review designs and code, and set engineering standards, with a growth path into formal team leadership as the team scales. 

Engage Beyond the Code: Work directly with product, customers, support, sales, and leadership to gather real-world insight, unblock fast, and align technical direction with the business. 

Collaborate Globally: Work closely with engineers and stakeholders across Israel, the US, Canada, and India. 

  

Qualifications

• 8+ years of deep backend/systems experience, strong Python, and real production experience in a multi-tenant microservice cloud environment

• Must: hands-on experience building LLM-based agents or agentic pipelines in production: orchestration, tool use, context engineering, model selection, cost and latency at scale

• Must: hands-on experience evaluating them: an evaluation harness, golden datasets, or benchmark suites you built or owned, and you can explain how you knew a change made the system better rather than different

• A track record of owning outcomes end to end, from early stage to scale, 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

• Technical leadership experience as a tech lead or team lead, with the intent to keep your hands in the code. Formal management experience is a plus

• An All-Around Player: independent, execution-focused, and happy to build whatever it takes

• Excellent English for working effectively across time zones
