c/side is hiring a Senior Growth Marketer to own and drive top-of-funnel growth through SEO, SERP, LLM optimization, and performance advertising. You will fully own the growth plan for 1-2 product segments, serving as the direct responsible individual for tracking and strategy.

What You'll Do

• Draft, implement, and improve top-of-funnel strategies to generate qualified leads.
• Build, optimize, and scale multi-channel marketing campaigns across LinkedIn, Google, TikTok, Reddit, newsletters, and emerging platforms.
• Own reporting: develop dashboards, run A/B tests, and translate metrics into actionable insights.
• Own the tech stack for GTM automation, creating systems that reduce inefficiencies and improve outcomes.
• Design, run, and analyze iterative growth experiments across the entire funnel: acquisition, activation, retention, and expansion.
• Automate lead scoring, account prioritization, and personalized outreach to maximize conversion rates.
• Instrument and maintain our analytics stack (GA4, PostHog, HubSpot, SEMrush, etc.) to provide a single source of truth on performance.
• Partner with GTM & Product to launch self-serve onboarding flows and product-led virality loops.
• Build automated lifecycle campaigns (email, in-app, Pylon) that convert free customers to paying, retained customers.
• Craft technical, value‑first narratives that resonate with security engineers & compliance leads.
• Report weekly insights and learnings.
• Evaluate and unlock new channels to achieve step-change growth.

What We're Looking For

• 3+ years driving growth for B2B SaaS with a clear track record of pipeline and revenue impact.
• Experience achieving a lot with little.
• Experience with tools like Clay, HubSpot, and email delivery platforms.
• Ability to evaluate and adopt new tools to maintain a competitive edge.
• Analytical to the core and comfortable building dashboards and explaining the 'why' behind the numbers.
• Autonomous: You'll own your domain and define how we grow.
• Experimentation mindset; you default to hypothesis → test → iterate and openly share wins and failures.
• Hands-on with the modern growth stack.
• Able to translate complex security concepts into crisp, compelling value propositions for technical buyers.
• Thrive in zero-to-one environments; biased toward action, embrace ambiguity, and ship fast without cutting corners.
• Exceptional written and verbal communication skills; you write tight copy and influence cross-functional stakeholders.
