## About the Role

* 6+ years of experience in software engineering, application security, or security engineering
 * Strong coding skills in at least one language (e.g., Python, Go, C#, JavaScript, Rust, C++)
 * Build and scale security automation in CI/CD pipelines (SAST, SCA, secrets detection, and fuzzing)
 * Solid understanding of application security fundamentals (OWASP Top 10, auth models, common vulnerabilities and mitigations)
 * Background with cloud environments, and modern architectures (microservices, APIs)
 * Working knowledge of Linux/Windows systems, networking fundamentals, and system-level security
 * Experience designing and implementing secure, scalable systems, including APIs, microservices, and distributed architectures
 * Ability to translate security risks into practical, scalable engineering solutions
 * Bachelor's degree in a relevant field or equivalent practical experience, * Experience building security platforms, tools, or developer frameworks
 * Knowledge of cryptography, PKI, TLS, and secure implementations
 * Experience with container security and Kubernetes
 * Experience building internal security platforms or developer tooling
 * Background of supply chain security (SBOMs, signing, provenance, build integrity), * Think long-term, building resilient and scalable security solutions rather than one-off fixes
 * Highly execution-focused and drive outcomes in fast-paced environments
 * Take ownership and proactively identify and mitigate risks
 * Collaborate effectively and influence engineering teams through practical solutions
 * Balance security and developer productivity to enable the business

## Description

* Design and build security controls, libraries, and guardrails directly in code
 * Develop and scale automated security tooling across CI/CD (SAST, dependency scanning, secrets detection, fuzzing, etc.)
 * Build and improve detection and prevention mechanisms for abuse, data exfiltration, and supply chain risks
 * Automate vulnerability triage, prioritization, and remediation workflows at scale
 * Integrate security into developer workflows and internal platforms to reduce friction and increase adoption
 * Design and implement security controls for agentic and AI-assisted workflows, building guardrails to mitigate risks such as prompt injection, data exfiltration, and misuse of developer and system privileges
 * Contribute to secure system design and architecture reviews, including threat modeling for new products and features
