Deliver high-quality, client-ready reports with clear risk ratings, business impact, and practical remediation guidance.
Collaborate with sales, customer success, and engineering teams to translate findings into product improvements.
Mentor junior consultants and contribute to methodology, tooling, and process enhancements.
Support compliance-driven assessments while maintaining an offensive security mindset.

5–10 years of current, hands-on experience in offensive security, red teaming, or penetration testing.
Strong background in web application penetration testing and internal network assessments.

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
What You’ll Bring
Must have strong experience in IT, business systems administration, or systems engineering, including experience leading a team
Must have deep hands-on experience administering enterprise SaaS platforms at scale, like Jira/Atlassia, suite required; experience with collaboration tools (Google Workspace/M365) or similar company-wide IT-owned platforms strongly preferred
Must have hands-on experience building and managing integrations on an IPaaS platform — Workato experience strongly preferred
Must have demonstrated experience building custom integrations/middleware using AWS services (Lambda, S3, RDS, API Gateway, EventBridge, or similar) for cases beyond IPaaS capability
Must have hands-on experience building or deploying AI agents, Projects, Skills, or Gems on at least one enterprise AI platform (Glean, Claude, Gemini, or AWS Bedrock), including connecting them to internal data sources and applications
Must have working knowledge of APIs, webhooks, data models, and integration patterns (REST, event-driven architecture)
Must have experience managing external contractors/vendors for custom development work, including scoping, oversight, and quality control
Must have strong stakeholder management skills and the ability to translate business requirements from non-technical teams (Legal, Finance, GTM) into technical solutions
-
Must have an understanding of access control, data security, and compliance considerations (SOC 2, ISO 27001, export control, or similar frameworks) as they relate to business applications and AI systems, along with a collaborative approach to working with IT Engineering on IAM/SSO needs
Minimum Education and Experience
Bachelor's degree in Information Systems, Computer Science, Business, or a related field, or equivalent practical experience
5+ years of experience in IT, business systems administration, or systems engineering
2+ years of experience in a leadership/management capacity (people and/or project management)
Experience supporting a distributed or remote-first workforce
-
Prior experience managing cross-functional requests, building integrations, and driving platform adoption in a hands-on capacity
Required Tech Stack Experience
Jira / Atlassian suite
Workato (or similar IPaaS platform)
AWS (Lambda, S3, RDS, API Gateway, EventBridge, Step Functions, or similar)
AI platforms: Glean, Claude, Gemini, and/or AWS Bedrock
Collaboration platforms (e.g., Slack, Google Workspace, Zoom)
APIs, webhooks, and REST/event-driven integration patterns
What Sets You Apart?
You've built or led a Business Applications, IT systems, or integration function in a fast-paced, high-growth environment and know how to scale enablement without losing quality or governance
You're comfortable being both a people manager and a hands-on architect for complex integration and AI agent builds
You've partnered with contractors or vendors to deliver custom middleware and know how to scope, oversee, and QA that work
You're a trusted partner across GTM, Finance, Legal, Engineering, and People, balancing self-service enablement with operational and security rigor
You know how to evaluate a request against native, IPaaS, and custom-build options and choose the right level of investment
Experience deploying AI agents, Projects, Skills, or Gems for real business use cases, not just experimentation
Relevant certifications such as Atlassian, AWS, Workato, or similar
Experience in high-growth SaaS or cybersecurity companies

Staff Defensive Security Software Engineer
Get to Know Us
Horizon3 is an innovative, rapidly growing cybersecurity company on a mission to help organizations proactively identify, fix, and verify exploitable vulnerabilities before they can be leveraged by cybercriminals. Our flagship product, NodeZero™, delivers autonomous pentests and security assessments that scale across complex environments, including internal, external, cloud, and hybrid cloud infrastructures. From small educational institutions to global enterprises, our platform is trusted by a wide range of organizations—IT and SecOps teams, MSSPs, MSPs, and consulting pentesters.
Our team blends former U.S. Special Operations cyber operators, startup engineers, and seasoned cybersecurity professionals. Together, we’re tackling the industry's toughest challenges: ineffective tools, false positives, alert fatigue, skills shortages, and the high costs and long timelines associated with traditional consulting. We are a culture of learn-it-alls—focused on collaboration, respect, ownership, and delivering results.
As a fully remote company, we prioritize flexibility and require a minimum 25Mbps broadband connection.
The Opportunity
We are looking for a Staff Security Researcher / Developer to join our Detection & Deception (DnD) Team to help build Horizon3’s deception capabilities. The team works across product, design, and engineering to deliver features such as Tripwires and Rapid Response.
This role will focus initially on evolving Tripwires — a threat detection and deception capability within the NodeZero platform that uses autonomous pentests to place decoys (honeytokens) along high-risk attack paths. When an attacker interacts with a tripwire, the system generates an alert so defenders can investigate and respond.
It's a great fit for someone who thrives in an agile, fast-paced environment and is excited to ship high-quality work that has a real impact on the cybersecurity landscape.
What You’ll Do
As a Security Engineer on the Tripwires team, you'll combine deep security domain expertise with hands-on full-stack development to design, prototype, and ship new security capabilities within NodeZero. You'll partner with product managers and designers to identify high-impact opportunities, and work alongside product engineers to quickly turn those ideas into MVPs and production features. Day-to-day work spans product research, threat-informed design, and feature development — with a particular focus on honeytoken and honeypot creation, deployment, and detection logic for Tripwires and adjacent products like Rapid Response. By building these capabilities, you'll deepen customer engagement with our platform and deliver novel solutions that measurably improve their security posture.
What You’ll Bring
Technical Leadership: Owns the end-to-end technical vision for the workstream and rallies the team around it — from blank doc through shipping, iterating, and deprecating.
Software Engineering: Production code contributions at Lead/Staff level in a modern backend language (Go, Rust, Python, or similar) in a service-oriented environment.
Self-Motivation: The ability to work independently with minimal supervision, demonstrating initiative and a high level of energy.
Collaboration: Work closely with other cross-functional partners to build and improve our product portfolio
Communication: Strong technical writing and documentation skills, with the ability to convey findings and methodologies to both technical and non-technical stakeholders.
Technical Design: Proficiency in designing, presenting, and evaluating technical solutions, ensuring high-quality software and secure development practices.
-
Team Leadership:
Sets and raises the technical bar (design reviews, code quality, operational discipline) by example rather than by mandate.
Mentors and enhances the engineers around them; Build the frameworks and architecture for others to do the best work of their careers.
Holds the team accountable to outcomes rather than activity; surfaces risks and tradeoffs early and in writing.
-
Product-Minded Technical Leadership:
Translates ambiguous product goals into concrete technical roadmaps.
Partners closely with PM — comfortable in PRD reviews, not just sprint planning.
Sequences an MVP without painting the team into a corner.
Required Qualifications
Python: Expert-level proficiency in large-scale Python software development.
Network Security: Deep experience with network security topics such as reconnaissance and lateral movement.
Windows Experience: Proficiency with Active Directory, Windows authentication, and other windows internals
Network Protocols: Strong understanding of network protocols such as SMB and WMI and their intricacies, including their role in exploitation vectors.
Database Experience: Experience with relational (Postgres) or graph (Neo4j) database systems.
Security Experience: Minimum of 4 years of experience in building offensive or defensive security solutions, ideally in endpoint, threat detection, or low-level systems.
Education: Bachelor's Degree in Computer Science, Computer Engineering or related field.
Equivalent experience may be considered if demonstrable through proof-of-concept write-ups, published vulnerability research, or similar achievements.
Preferred Qualifications
OSCP (Offensive Security Certified Professional), GCWN (GIAC Certified Windows Security Administrator) or equivalent certifications.
Previous experience in red teaming or penetration testing, incident response, detection engineering, deception technologies, or other deeply technical roles with relevant skill sets.
Previous experience working on large-scale software projects.
Experience administering, attacking, or defending cloud environments.
Knowledge of and experience with Docker and containerization technologies.
Familiarity with identity and directory services such as Active Directory, Entra ID, or Okta.
Familiarity with cloud authentication and authorization technologies such as Azure Service Principals or AWS IAM.
Travel Required:
We are a fully remote company, and this job may require up to 5% of travel to be successful.
Compensation and Values:
At Horizon3, we believe that our people are our greatest asset, and our compensation philosophy reflects this core value. We are committed to fostering an environment where all employees feel valued, respected, and rewarded for their contributions.
