Job description

Get to Know Us

Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find and 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 ITOps/SecOps teams, consulting pentesters, and MSSPs and MSPs.

We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, 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.

What You'll Do

We are seeking a Manager, IT Engineering to build and lead our Business Applications (BizApps) function within IT. This is a hands‑on leadership role for someone who can set direction, build a new team, and stay close enough to the work to enable every part of the business through the applications, integrations, and AI tooling that power their day‑to‑day operations.

This role will lead the team responsible for administering IT‑deployed, company‑wide applications; building and maintaining integrations --- primarily through our IPaaS platform, Workato, and, where needed, custom middleware built on AWS; and designing and deploying AI agents across our AI platform stack (Glean, Claude, Gemini, and/or AWS Bedrock) to automate and enable work across GTM, Finance, Legal, Engineering, and other teams. The ideal candidate brings strong technical breadth across applications, integration architecture, and AI enablement, along with the ability to partner effectively across every department in a fast‑growing organization. By strengthening our BizApps function, this role will directly enable business scalability, operational efficiency, and cross‑functional productivity.

This role will be responsible for ….

• Lead, coach, and grow the Business Applications (BizApps) team, including ownership of IT‑deployed application administration, integration development, and AI agent enablement
• Set priorities and operating rhythms for the team, balancing day‑to‑day requests, escalations, integration/AI build projects, and long‑term platform improvements
• Serve as a hands‑on leader for the BizApps function, stepping in on complex builds, architecture decisions, and high‑priority cross‑functional requests
• Own administration, configuration, and lifecycle management of applications where IT is the accountable, company‑wide deploying owner (e.g., Jira, collaboration tools, and similar platforms as designated) --- distinct from applications owned by other departments (e.g., HRIS owned by People Ops)
• Build and maintain governance around permissions, roles, licensing, and access models across BizApps‑owned platforms, partnering with IT Engineering on any identity and access management (IAM) needs tied to SSO/IdP
• Design and implement workflows, automations, custom fields, and reporting structures within IT‑owned applications (e.g., Jira) that let departments such as GTM, Finance, Legal, and Engineering self‑serve where appropriate, and get expert support where they can't
• Serve as the primary owner and architect of our Workato IPaaS instance, building, testing, and maintaining recipes/connections that integrate systems across the business
• Evaluate each integration request against a clear decision framework: native integration first, Workato second, and custom AWS‑based middleware only when neither can meet the requirement due to complexity, scale, or data sensitivity
• Architect, oversee, and/or build custom integrations using AWS services (Lambda, S3, RDS, API Gateway, EventBridge, Step Functions, etc.) for integrations that fall outside Workato's capabilities
• Manage relationships with third‑party development contractors/vendors for custom build‑outs, including scoping, technical requirements, QA, and handoff to internal support
• Design, build, and deploy AI agents, Projects, Skills, and/or Gems across our AI platform stack (Glean, Claude, Gemini, AWS Bedrock) to solve specific business problems for GTM, Finance, Legal, Engineering, and other functions
• Own the intake and evaluation process for AI agent requests, assessing feasibility, data sources, security/compliance implications, and the right platform for a given use case
• Establish guardrails, access controls, and data handling standards for agent deployments in partnership with IT Engineering and Security/Compliance, including least‑privilege access and monitoring for misuse or drift
• Maintain an accurate inventory and lifecycle plan for owned applications, integrations, and deployed agents (ownership, purpose, data access, review cadence) to support audits and prevent unmanaged risk
• Partner closely with IT Engineering, Security, and Legal/Compliance to ensure application, integration, and AI enablement practices align with security requirements, access control policies, and regulatory obligations
• Create metrics, dashboards, and operational reporting that communicate BizApps performance, delivery velocity, and platform health to leadership
• Drive continuous improvement across the BizApps function, including tooling, workflows, documentation, and self‑service capabilities
• Demonstrate a commitment to integrity, process improvement, and customer satisfaction

As a Manager, you will be responsible for:

• Recruiting and onboarding talented individuals to support our organizational goals
• Mentoring, coaching, equipping, and developing your team
• Recognizing and retaining high performers
• Leading horizontally with peer management and senior leaders
