Experience with stream processing or batch processing frameworks is valuable. • Solid grasp of platform design principles, API design, system integration patterns, and CI/CD practices for rapid, reliable deployments. • Hands-on experience with cloud infrastructure and services (AWS, Azure, GCP), including networking, compute, storage, and managed services. • Strong operational expertise: monitoring, observability, logging, tracing, and incident response for production systems. • Deep familiarity with network protocols, multiple operating systems (Windows, Linux, macOS), and enterprise technology stacks. • Hands-on experience building or leading engineering for B2B SaaS or platform products, ideally within a security or cybersecurity company. • Working knowledge of databases (PostgreSQL, MongoDB, Neo4j, or similar) and experience designing schemas and query patterns for operational and analytical workloads. • Understanding of cybersecurity fundamentals and familiarity with penetration testing, vulnerability assessment, or automated attack workflows. • What Sets You Apart? • Experience building or scaling production penetration testing, vulnerability management, or security assessment platforms. • Background in distributed computing, grid computing, or large-scale parallel execution systems. • Experience with graph databases and query optimization for complex data relationships. • Demonstrated expertise in mentoring teams on platform engineering or infrastructure best practices. • We are a fully remote company, and this job may require up to 10 - 15% of travel to be successful.
Responsibilities
• As Director of Pentest Platform, you'll lead the strategy, design, and development of the core pentest execution, orchestration, and data infrastructure that powers NodeZero's autonomous testing capabilities. You'll manage four engineering teams responsible for building and scaling the platform systems that execute, coordinate, and analyze pentests across complex enterprise environments. This role sits above our platform engineering leaders and will play a key role in scaling the platform organization as we continue to expand NodeZero's reach and sophistication. • Leadership & Strategy: • Lead and scale Horizon3.ai http://Horizon3.ai's Pentest Platform organization, overseeing three teams: Execution Engine (pentest runtime and distribution), Orchestration (scheduling, coordination, and workflow), and Pentest Data Platform (result collection, processing, and analytics). Set clear technical and product direction for how NodeZero executes and analyzes pentests at scale across distributed environments. • Product Ownership: • Partner closely with Product, Proactive Offense (offensive capabilities), and GTM teams to define platform requirements and deliver capabilities that enable NodeZero's pentest execution at scale. Drive execution from proof-of-concept through production, transforming architectural innovations into reliable, performant platform features. • Technical Depth: • Stay hands-on enough to guide architectural decisions around data models, orchestration patterns, and data pipeline design. Mentor technical leads in building resilient, distributed systems that power NodeZero's core testing infrastructure. • Build, mentor, and scale three diverse engineering teams focused on infrastructure, platform automation, and data engineering. Foster a culture of collaboration, operational excellence, and systems thinking that bridges infrastructure and product perspectives. • Cross-Functional Collaboration: • Collaborate across engineering, product, and GTM to align platform roadmap with business priorities and offensive capabilities. Ensure reliable, scalable delivery of pentest execution infrastructure that enables rapid innovation in attack content and customer value. • Application Note • In any materials you submit, you may redact or remove age-identifying information such as age, date of birth, or dates of school attendance or graduation. You will not be penalized for redacting or removing this information.
