Staff Software Engineer, Tripwires

GET TO KNOW US Horizon3.ai http://Horizon3.ai 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 Software Engineer 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 Staff Software 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,
