Senior Growth Marketing Manager at Magnitude in San Francisco, CA

About Mangitude

Magnitude (formerly Archer Faris) is pioneering the world's first 100% multi-agent approach to enterprise security, starting with Third-Party Risk Management, a domain that is mission critical, deeply human, and notoriously broken. Founded by security and AI leaders from Abnormal Security, Amazon Alexa, Proofpoint, and other iconic companies, we are well-funded and entering the market at a moment of significant tailwind. The window to shape how this category gets defined is open right now

About this Role

We’re looking for a Senior Growth Marketing Manager who can both lead strategy and roll up their sleeves. You’ll architect integrated marketing programs that build awareness and generate qualified enterprise pipeline. You’ll manage agency partners, own the digital ecosystem, and pioneer next-generation tactics like Answer Engine Optimization (AOE) and AI-driven workflows and personalization.

Key Responsibilities:

• Lead the Growth and Pipeline Strategy: Design and execute the integrated marketing plan spanning SEO, paid, content, social, and lifecycle programs. Develop the roadmap and budget to hit awareness, conversion, and pipeline targets across enterprise and self-serve motions. Own marketing performance reporting, pipeline attribution, and channel optimization. Scale what works — build repeatable playbooks that can later support a growing team.
• Own Digital Marketing and Website Performance: Lead the website strategy and optimization — from content and UX to conversion flow and experimentation. Drive SEO / AEO visibility across traditional and generative-AI search surfaces. Manage digital platforms (CMS, analytics, marketing automation, experimentation tools). Partner with design and product teams to ensure the site reflects brand, product, and conversion goals.
• Manage Agencies and Budget: Own the paid media and ad-agency budget. Direct all external vendors - SEO, performance marketing, creative, content syndication - for accountability and measurable ROI. Reallocate spend dynamically based on performance data and strategic priorities.
• Build Content and Lifecycle Programs: Partner with external services, PR team, Marketing, Sales and executives to develop narratives that differentiate and convert. Lead the creation of guides, webinars, customer testimonial videos, and thought-leadership content aligned to buyer journeys. Deploy marketing automation, personalization, and AI content generation to increase speed and relevance.
• Provide Cross-Functional Leadership: Collaborate with Sales and Product to align messaging, campaigns, and funnel analytics. Establish KPIs, dashboards, and quarterly growth OKRs.

Requirements:

• 5+ years in B2B SaaS demand generation, growth, or digital marketing — ideally in an enterprise + PLG hybrid model.
• Proven record of scaling awareness and pipeline from Series A through Series C stages.
• Expertise in SEO, SEM, paid social, CRO, lifecycle automation, and analytics
• Experienced managing marketing budgets and multiple agency relationships
• Fluent in AI marketing & sales tools (automation, personalization, content generation, experimentation)
• Comfortable balancing strategic leadership with hands-on execution
• Exceptional communicator who can align execs, data, and creative to drive measurable outcomes

Benefits:

• Competitive salary and incentive stock options (ISOs)
• Health, dental, vision, life, and disability insurance
• 401(k) retirement plan
• Health savings account (HSA) available with company contribution
• Flexible spending accounts (FSAs)
• Paid holidays & Flexible PTO
• Hybrid work environment
