About The Position

Horizon3 is seeking a senior, hands-on IT Engineer to own and improve the automations that support company operations. The role takes ownership of the existing automation backbone from the start, maintaining its reliability while building workflows that reduce manual work and advancing IT configuration, infrastructure, and identity toward versioned, reviewed, repeatable code. The engineer sets priorities with little supervision and partners with Security Operations and IT Business Applications where responsibilities overlap. The role targets automation-flow reliability of 99% or better each calendar month and reports reliability, failures, and their causes to IT leadership. Horizon3 is a fast-growing, fully remote cybersecurity company. Its NodeZero platform provides production-safe autonomous penetration testing and assessment operations for organizations of varying sizes. The company describes its culture as centered on respect, collaboration, ownership, results, integrity, process improvement, and customer satisfaction. This position may require up to 10% travel.
