Growth Marketing Manager

HiO is an AI business partner for small and medium business owners that helps them grow through every customer conversation. The Growth Marketing Manager will own the growth engine end-to-end, including paid acquisition, lifecycle marketing, activation, experimentation, analytics, conversion optimization, and AI-powered marketing operations. The role partners closely with Product and Engineering in a hands-on, early-stage environment.

Responsibilities:

• Paid media : strategy, channel selection, budget allocation, campaign build, and optimization across paid social and search- Full ownership from planning through performance reporting
• Channel experimentation : not limited to the channels listed above - expected to identify, pitch, and test new or unconventional channels as opportunities arise, and kill what doesn't work fast
• Growth analytics : funnel instrumentation and reporting (PostHog, GA4). Tracks CAC, LTV, conversion by plan tier, and activation metrics. Surfaces insights and recommends where to invest next
• Website conversion optimization : landing pages, signup/trial flow, on-site A/B testing
• Free-to-paid conversion & activation : owns the free-to-paid funnel across plan tiers in partnership with Product. Identifying the "aha moment," reducing time-to-value, and driving trial/freemium users toward upgrade
• Onboarding optimization : Onboarding flow iteration to get new users to first value faster, in coordination with Product
• Referral : builds and owns referral mechanics to drive user-driven acquisition
• Experimentation : runs structured A/B tests across paid, lifecycle, on-site, and in-product; builds a testing cadence from scratch
• Marketing automation & AI ops: builds and maintains the AI/automation layer of the growth engine. Think automated reporting, AI-assisted creative testing, agentic workflows for campaign management and iteration
• Cross-functional work with Product and Engineering : partners directly with Product and Engineering - comfortable operating without a dedicated growth engineer
• Agentic by default: use AI agents to draft, analyze, monitor, and execute. Spend your time on judgment and strategy, not production
• Lifecycle & retention marketing: onboarding flows, activation campaigns, re-engagement, and win-back sequences (Customer.io). Strategy and iteration, not just execution
• Upgrade & expansion: owns campaigns and in-product prompts that move users up plan tiers as usage grows

Requirements:

• 5+ years of experience in growth marketing, including at least 3 years at a PLG SaaS company (ideally SMB or vertical SaaS, Seed or Series A)
• Full-funnel growth ownership (not just execution within someone else's strategy) at a PLG SaaS company, ideally SMB or vertical SaaS, seed or series A
• Experience building growth infrastructure and processes from scratch, not just optimizing existing systems
• Expert in tracking, reporting, and quickly iterating - CAC, LTV, payback period, and funnel/activation metrics
• Hands-on paid media experience with real budget accountability
• Comfortable operating with minimal engineering support; a hands-on builder who thrives in an early-stage environment
• Demonstrated AI fluency: can show specific examples of workflows they've automated with AI
• Wants to stay hands-on in the work. No expectation of building or managing a team in the near term
