[Hiring] Head of Growth @Siena AI

Role Description

Siena is the CX operating system for brands. The product is shipping faster than the market can absorb it. We have the customers, the proof, the momentum. What we need is someone who turns all of that into compounding growth.

You will own how Siena grows:

• New customers, existing customers, and everything between them.
• Demand creation, product launches, brand, content, expansion, retention as a marketing motion.

You work directly with both founders. You build the function. You build the team.

What you'll own:

• New customer acquisition.
• Demand creation across every channel that works: brand, content, social, events, paid, partnerships.
• Existing customer growth: expansion, adoption, retention as a marketing problem.
• Product launches end to end: every release becomes a market moment.
• Category leadership: you own how that category gets defined and adopted.
• Brand and momentum: the campaigns, content, and presence that make Siena the first name in CX AI.
• The growth system: you build the AI agents and workflows that let one person move like ten.

Qualifications

• AI-native: you build agents and systems.
• A builder: you've shipped something from zero.
• A storyteller: you write and shape narrative.
• Creative and analytical in equal measure.
• Scrappy: you ship in hours and experiment constantly.
• Fluent in selling AI: you understand what makes AI products different to market.

Benefits

• Meaningful impact: your work directly shapes our product and company.
• Globally distributed team working at the bleeding edge of CX and AI.
• Great salary plus the opportunity for equity or stock grants.
• Learning budget: if you're growing, so are we.
• The thrill of building something new: join us at a stage where your contributions matter most.
• AI-fluency: make AI your second nature.
• Tackle unsolved problems: we’re redefining how customer experience will look like in the next decades.
