Confiant is cybersecurity built for advertising. We secure the ad economy from the inside out, providing real-time intelligence and precise controls that detect and block malvertising, scams, disruptive creatives, and compliance risks before they reach users. By disrupting the business models of bad actors, Confiant empowers digital media to enforce standards, ensure quality, and uphold trust across the ad economy. We protect what matters most — revenue, reputation, and relationships — securing the foundation that allows good advertising to thrive.

As a Support Engineer at Confiant, you are the front line when a malicious or disruptive ad reaches one of our publishers or platform partners. You'll triage and resolve live incidents: forced redirects, scareware, malware, scam and policy-violating creatives, often under time pressure and with revenue or reputation on the line. Between incidents, you'll review reported creatives and make blocking decisions, verify and enable integrations, investigate discrepancies by tracing ad behavior across devices and environments, and feed what you learn back to our Product and Security teams.

This is a hands-on, technical, customer-facing role. Success requires a strong technical foundation, sharp investigative instincts, calm judgment during escalations, and a genuine customer-first mindset.
