Application Security Engineer

Key Responsibilities

• Own the integration, configuration, and output quality of security tooling that powers our platform
• Tune outputs to maximize signal and minimize noise — decide what to surface, what to suppress, and what to enrich
• Design rules, severity scoring, and triage flows that make findings actionable rather than overwhelming
• Build the security judgment layer on top of underlying tooling — context-aware prioritization and exploitability reasoning
• Partner with engineers on how findings are presented in the UI and how remediation flows work
• Work with PM and design on roadmap priorities, providing the security expertise that drives what to build next
• Review and shape architectural choices that affect security outcomes
• Engage with customers directly to understand how they use the platform and what's blocking adoption
• Benchmark our output quality against competitors and close gaps where they exist
• Contribute back to the open source security tooling we depend on where it makes sense

Qualifications

• 5+ years of application security experience, with significant time shipping security products
• Strong programming skills in at least one of Go, Python, or TypeScript
• Hands-on experience tuning security tooling for production use — reducing false positives, building suppression logic, designing severity models
• Understanding of vulnerability research, CVE/CWE taxonomies, and exploit reasoning
• Experience determining what makes a security finding actionable vs. just technically true
• Excellent communication skills and comfort working directly with customers
• Pragmatic approach to building things fast without unnecessarily complicating things
• Experience thriving in a fast-moving, start-up engineering environment

Nice-to-Haves

• Prior experience shipping a security product at a vendor
• Contributions to open source security tooling
• Offensive security background or OSCP / similar certifications
• Hands-on experience with LLM agents, tool use, or autonomous AI systems
