Job description

SUMMARY

Theori is a global leader in offensive security, founded by the world's most elite hackers. With a decade of unparalleled technical expertise, we're revolutionizing the cybersecurity paradigm with Xint, our AI-native AppSec platform spanning Xint Web (autonomous web app penetration testing) and Xint Code (AI-powered code security). Xint has been featured in The Verge, is in production with customers like Samsung Electronics, and is being adopted by security teams who want hacker-grade testing without hiring an army of pentesters.

• Location: Remote (US/CAN),
• Type: Full-time
• Experience: 6+ years

KEY RESPONSIBILITIES

• Own paid campaign execution end to end across LinkedIn Ads, Google Ads search and display, and retargeting: audiences, targeting, budgets, bidding, creative trafficking, UTMs and conversion tracking.
• Test new paid channels, including Reddit, G2, and security-focused publishers and newsletters, and scale what returns.
• Run structured A/B tests on audiences, offers, copy and landing pages, document the results, and retire what does not work.
• Own HubSpot Marketing Hub as Xint's analyst and power user: lead capture, forms, landing pages, lists, segments and nurture workflows.
• Own lead scoring, lifecycle stages, lead routing and the MQL-to-SQL handoff with Sales, and keep CRM data clean through properties, deduplication, enrichment and governance.
• Own the Xint website: page updates, new pages, navigation, the demo request path, and fast on-brand landing pages for campaigns, launches and events.
• Run conversion rate optimization against demo requests, and own technical and on-page SEO, site speed, GA4 and Google Tag Manager.
• Build HubSpot dashboards and attribution reporting that tie spend to pipeline and revenue, and report monthly with a clear call on what to scale, fix or cut.

REQUIREMENTS

• 6+ years in performance, growth, or demand gen marketing, with at least 4 in B2B SaaS.
• Direct, hands-on management of paid budgets, including LinkedIn Ads and Google Ads, with results you can walk us through.
• Expert-level HubSpot: you've built workflows and lead scoring from scratch and set up attribution reporting.
• Hands-on Webflow expertise, including CMS collections, components and publishing workflow, with a record of owning a B2B company website.
• Working knowledge of SEO, GA4 and Google Tag Manager, plus conversion tracking, UTMs, pixels and ad platform integrations.
• Comfort with data: you build your own reports, read a funnel, and make budget calls from the numbers.
• A testing mindset, with a record of experiments that moved conversion rate, cost per opportunity or pipeline.
• Experience marketing to technical or senior buyers, where long cycles and buying committees are the norm, and clear written communication across marketing, sales and leadership.

NICE TO HAVE

• Experience marketing cybersecurity, DevSecOps or developer-adjacent products to CISOs and security teams.
