  • Standout: AI-native operator using AI to scale experimentation and multi-channel growth

Job Description

Responsibilities

  • Own net-new business meeting generation as the primary success metric, driving pipeline through paid, organic, and experimental channels
  • Plan, launch, and optimize paid ad campaigns across search, social, and display to acquire qualified prospects
  • Build and run ABM programs targeting high-value accounts in coordination with sales
  • Develop and execute AEO/GEO strategies to capture demand from AI-driven search and answer engines
  • Design and run social campaigns that drive awareness, engagement, and inbound interest from target personas
  • Operate a structured experimentation program — continuously testing new growth channels, messaging, creative, and tactics, then scaling what works into repeatable systems
  • Leverage AI tools across every workflow — from campaign ideation and content creation to audience targeting, personalization, and performance analysis
  • Partner cross-functionally with sales, product marketing, and marketing ops to align on ICP, messaging, and pipeline goals
  • Own campaign analytics and attribution — build dashboards, track performance, and report on pipeline impact to inform budget and strategy decisions
  • Support outreach efforts by collaborating on sequences, content, and targeting that reinforce outbound and inbound motions together

Requirements

  • 2–5+ years in B2B demand gen, growth marketing, or acquisition — ideally in SaaS or cybersecurity, with direct experience owning pipeline targets
  • Proven track record of generating qualified pipeline through paid and programmatic channels — not just managing campaigns, but building them from scratch and tying them to revenue
  • AI-native operator — actively using AI tools in day-to-day workflows, with clear examples of using AI to move faster or scale output. Clay experience highly desired
  • Strong experimentation discipline — knows how to structure tests with hypotheses, run them quickly, measure results, and decide what to kill vs. scale
  • Proficiency in modern marketing and analytics tools — HubSpot (or similar), Google Ads, LinkedIn Ads, and comfortable in spreadsheets and dashboards
  • Working knowledge of AEO/GEO and organic acquisition levers — understands how AI-driven search is changing demand capture and has ideas (or experience) on how to win there
  • Cross-functional collaboration chops — has worked closely with sales, SDR/BDR teams, and marketing ops to align campaigns with outbound motions and pipeline goals
  • Builder mentality with high ownership — comfortable in ambiguity, doesn't wait for a playbook, creates one. Has operated in early-stage or high-growth environments where they had to figure things out
  • Reside in San Francisco, CA or surrounding areas and able to work hybrid

Preferred

  • You have a successful track record leveraging AI to drive pipeline across multiple platforms and can show measurable impact on CAC and pipeline
  • You are comfortable working in the platforms daily, not just reviewing dashboards
  • You have experience with both traditional SEO and emerging tactics like AEO and GEO
  • You thrive in environments where you can experiment, test, learn, and iterate quickly
  • You can translate data into actionable insights and communicate performance clearly to stakeholders
  • You have worked in B2B, ideally in cybersecurity or SaaS categories

Benefits

  • This is not just a job. It is an opportunity to be part of a team that is redefining cybersecurity and AI safety. We believe today's talent is tomorrow's success, and we are committed to creating an environment where you can do the best work of your life.
  • Competitive compensation and meaningful equity with a direct stake in Harmonic's success
  • Comprehensive benefits including health, dental, vision, and 401k matching
  • A small, passionate team that values transparency, creativity, and learning
  • Thoughtful leadership that cares deeply about growth, impact, and people
  • Annual global offsites
  • The chance to directly shape both our product and our culture as we build a category-defining company
