Lead Security Engineer

About CodeRabbit

CodeRabbit is an innovative research and development company focused on building extraordinarily productive human-machine collaboration systems. Our primary goal is to create the next generation of Gen AI-driven code reviewers: a symbiotic partnership between humans and advanced algorithms that significantly outperforms individual engineers. We combine language models with human ingenuity to push the boundaries of software development efficiency and quality.

Role Overview:

CodeRabbit is on a mission to empower developers with lean, high-performance tools-they move fast, and so do the threats. That's why we're looking for a battle-tested Lead Security Engineer who's been in the trenches and can architect, harden, and defend our infrastructure, tooling, and ecosystem.

As our Lead Security Engineer, you'll lead security engineering at CodeRabbit, infusing security into every layer of our product and infrastructure. You become the steward of resilience, incident response, and proactive defense at scale.

Responsibilities:

• Own the security roadmap - craft and execute a strategic security engineering plan that aligns with CodeRabbit's fast-paced engineering cadence.
• Boost resilience - champion defense-in-depth tactics: threat modeling, secure design reviews, hardening, CI/CD integration.
• Be Incident Commander - spearhead security incident response and recovery: triage, resolve, root cause, and turn those learnings into stronger systems.
• Tools & automation - build or integrate security tooling (SAST, DAST, SIEM, EDR, monitoring) into the developer workflow without slowing delivery.
• Embed security fluently - partner with engineering and product teams to bring secure practices early into planning and daily workflows.
• Talent & culture - help to hire, coach, and mentor a scrappy, resilient security engineering team; elevate security awareness across the company.
• Compliance & policy - establish security standards, frameworks, or processes that evolve as we scale-but remain lean and developer-friendly.

Qualifications:

• Battle-tested experience : 8+ years in security engineering, incident response, or correlated fields-bonus if you've led through a major production breach or targeted attack.
• Technical depth : Extensive experience with security across software and infrastructure-threat modeling, pen testing, secure CI/CD pipelines, cloud security, incident response.
• Strategic mindset : Ability to translate risk into actionables, communicate tradeoffs with engineering/product leadership.
• Praxis over theory : You've taken production systems down (intentionally or unintentionally) and built them back stronger.
• Security in chaos : Experience in pressure situations-with clarity, direction, and calm.
• Developercentric approach : You can speak fluent dev-tools, empathize with fast-moving teams, and secure them without slowing them down.

Bonus Points:

• You've implemented DevSecOps tooling and orchestrated shiftleft security in developer pipelines.
• You've recovered from (or prevented) a critical security event, and turned that into an engineering culture improvement.
• Experience in a devtools, SDK, or platform-heavy company.
• Hacker mindset + operational discipline - pentests, disaster recovery, threat hunting, tooling, cloud environments.
• Certifications like CISSP, CISM, CEH, or relevant cloud security certs.

Why Join Our Engineering Culture?

• CodeRabbit is building the next generation of AI-native developer tooling - starting with code review. We combine large language models with deep software engineering context to help teams ship faster, catch more bugs, and make better architectural decisions at scale.
• We are a high-ownership engineering culture. That means no passive execution, no waiting for perfect tickets, and no narrowly defined task boundaries. Engineers here find problems before they're assigned, use AI as a core part of how they build, ship with judgment, and own outcomes from proposal to production.
• Our operating philosophy : bias toward action, ship the smallest necessary coherent slice, validate proportional to risk, watch what happens, and make the system better. AI drafts; humans decide. Speed matters, but so does understanding what you ship.
• This opportunity will be energizing for people who want real ownership, pace, and high standards . It's uncomfortable for people who prefer slow consensus or heavily managed workflows.
• If you want to build tools that are changing how software gets written, and be held to the standard that the best engineers thrive under; we'd love to talk.
