Description

Who We Are

At Backslash, we're building the future of application security for the "vibe coding" era—the most significant shift in software development in decades. While AI coding environments like Cursor and Windsurf are powerful, they also introduce new, unknown risks into the software supply chain. We empower developers and security teams to ride this wave with confidence.

Our comprehensive approach provides visibility and governance of IDEs, finding MCP and LLM risks with built-in rules that transparently ensure AI-generated code is secure. This creates transparent guardrails for developers without hindering their flow. We do this with our App Graph, the underlying technology that analyzes and models code from all sources—human or AI, custom or third-party—to provide a unified, contextual, and actionable approach to security. Our solution is purely agentless and deploys in minutes.

The Mission: What You'll Do

You are a key player in defining our security posture, leading a team of four to drive innovation and quality in our core security engines. This isn't just about vulnerability analysis; it's about shaping the future of AppSec research and making our product the most accurate on the market.

  • Lead the Team: Mentor and guide a team of four security analysts and researchers, fostering a culture of excellence and deep technical curiosity.
  • Shape the Engines: Lead the analysis and definition of benchmarks for our AppSec engines, constantly working to improve their accuracy and reduce false positives.
  • Be the Authority: Take ownership of our AppSec and threat-intelligence activities, providing the final word on true AppSec vulnerabilities in production environments.
  • Innovate and Build: Design, build, and develop advanced analysis tools both for in-house use and as part of our core product.
  • Drive Quality: Champion a culture of innovation, technical excellence, high product quality, and timely delivery within our agile, production-critical environment.

The Profile: What You'll Bring

We're looking for a leader who is both a seasoned security expert and a builder. You are driven by a passion for solving complex, real-world security challenges.

  • Experience that Counts: You have at least 3 years of experience in AppSec, with a proven track record as an AppSec analyst or security researcher. We are open to a talented individual who is ready to step up and lead a team for the first time.
  • Security Mastery: Deep understanding of the OWASP Top 10 and hands-on experience in vulnerability analysis and remediation.
  • Product-Minded: Experience with Cyber Security and Application Security solutions, with a keen eye for improving product quality and customer value.
  • A Hunger for Disruption: You have a passion for startups and an unwavering desire to take full ownership of problems, not just tasks. You thrive on the challenge of doing what needs to be done.
  • The X-Factor (Advantage): You have a vision for what security should be, and you've demonstrated it through:
  • Strong coding skills in Python or TypeScript/JavaScript for building and developing security analysis tools.
  • Experience in Security Research.
  • Experience in SaaS products and with Cloud technologies.
