Director of Engineering, Threat Research

Leads the engineering teams behind Horizon3.ai's NodeZero Rapid Response and Threat Hunting products. Rapid Response turns new vulnerability and threat signals into fast, safe validation of what is exploitable in each customer's environment, and Threat Hunting helps customers find out whether attack paths NodeZero discovered were already used. This is a people and portfolio leadership role over distributed teams in the US, Europe and Asia.

The director owns engineering strategy, delivery and organisational health for both teams, hiring and developing engineering managers, technical leaders and senior engineers. A major task is building a follow-the-sun vulnerability research capability with sub-teams in Europe and Asia, including the staffing model, handoffs and playbooks for round-the-clock coverage. The role also guides AI-assisted research workflows that keep expert verification and safety controls in place, shapes investigation capabilities from security telemetry and detection logic, and sets quality, reliability and evaluation practices so customers can trust the findings.

Horizon3.ai wants significant experience leading software teams that build customer-facing products, ideally in cybersecurity, including leading multiple teams and developing managers. Experience scaling distributed teams with sustainable 24/7 coverage, strong technical judgement across architecture, automation and data systems, and a record of taking complex capabilities from research to production are expected, along with production experience in a language such as Python, Go or TypeScript. A degree in computer science, engineering or cybersecurity, or equivalent experience, is required. The role is remote in the US.
