Senior Engineering Manager, User Platform & Enterprise at Horizon3ai

Get to Know Us Horizon3.ai [Upgrade to PRO to see link] is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find, fix and verify exploitable attack vectors before criminals exploit them. Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by IT Ops/SecOps teams, consulting pentesters, and MSSPs and MSPs. We are a fusion of former U.S. Special Operations cyber operators, startup engineers & operators, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools and false positives, resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn-it-alls, committed to a culture of respect, collaboration, ownership, and results. As a remote first company, we require minimum 25Mbps consumer grade broadband connection. What You'll Do We’re looking for a Senior Engineering Manager to lead our User Platform & Enterprise team — a high-impact group within our Application Platform team which drives all user settings and enterprise capabilities across the product, and helps improve our client experience overall. This is a technical leadership role focused on driving excellence in Enterprise user experience, creating a cohesive user platform vision, and pushing for explainability and scalability in our licensing framework. The User Platform & Enterprise team owns our base user platform experience, our entitlement framework and feature flagging systems, and many of our key enterprise differentiating features. This is an ideal opportunity for someone who loves diving into ideal user flows and information display, and cares deeply about building sustainable user-facing platforms which can scale for both mid-market and enterprise customers. What You’ll Bring - Experience leading teams of 6-10 cross functional software engineers. - Proven experience leading highly technical backend or platform engineering teams — ideally within a SaaS, cybersecurity, or cloud-scale environment. - Experience leading initiatives around authentication, authorization, user settings, tenant management, or auditability. - Experienced with multi-persona products, particularly building features for Enterprise clients. - You think in terms of platforms and systems, not just features, and you balance security, usability, and scalability in every decision. BONUS POINTS - Experience designing multi-tenant SaaS platforms or MSP-oriented capabilities. - Exposure to audit/compliance frameworks (SOC2, FedRAMP, ISO 27001). - Background in cybersecurity, identity management, or enterprise SaaS security features. - Experiencing managing tech leads or other managers. Required Tech Stack Experience - Strong background in backend engineering and/or platform engineering. - Expertise in at least one object-oriented programming language (Python strongly preferred; open to Go, Java, C++, or similar). - Familiarity with ETL pipelines, data flow orchestration, and database performance optimization (PostgreSQL, Neo4j, or equivalent). - Understanding of cloud infrastructure and services (AWS, Azure, or GCP), including networking, compute, and storage fundamentals. - Exposure to infrastructure-as-code and deployment concepts (e.g., Terraform, Docker, Kubernetes, CI/CD tooling). - Experience with observability and monitoring stacks (Prometheus, Grafana, OpenTelemetry, etc.). - Understanding of security and reliability best practices, especially in a multi-tenant SaaS or cybersecurity environment. - Knowledge of Linux-based systems (Ubuntu, Kali, etc.) and modern development practices for distributed environments.
