Meet Siena, the first intelligence layer for customer experience. We are building an operating system of AI agents that learn, remember, and act across every customer touchpoint—from support conversations to shopping experiences to voice and social media interactions. Siena doesn’t just automate support; it powers shopping agents, builds persistent customer memory, generates actionable business insights, and creates empathetic interactions that feel human. We’re transforming how businesses understand and connect with their customers, turning every interaction into intelligence that makes the next one better.
The team is a small, distributed group punching well above our weight. Every person has outsized impact because we built leverage into everything we do. This philosophy makes us faster and, frankly, more fun to work with. If you’re excited about building something that doesn’t exist yet, keep reading.
About The Role
This role is built for someone who bridges the gap between customer wins and sales ammunition—turning product launches into market moments, customer stories into case studies, and competitive situations into wins. You’ll work directly with our co-founders and GTM team to create the systematic marketing infrastructure that drives enterprise deals. If you have experience turning B2B customer success into compelling marketing assets that close deals, this is your opportunity to build a marketing function from the ground up.
What You’ll Do
- Own end-to-end product launches—external market releases and internal team education—with full positioning, enablement, and amplification.
- Manage the complete customer success story lifecycle from identification through interviews, content creation, legal approvals, and distribution.
- Build and run Siena Academy, creating curriculum that drives customer adoption and product value.
- Create competitive intelligence system including battlecards, takedown decks, and positioning frameworks that help sales win.
- Develop ROI calculators and business case materials that articulate value differentiation.
- Build visual asset library with case studies, one-pagers, before/after comparisons, and templates sales can use immediately.
- Establish tight feedback loops with sales, CS, and product to understand which assets drive pipeline and close deals.
- Track marketing asset usage, pipeline impact, win rates, and revenue attribution to optimize what’s working.
Who You Are
- 3-5+ years in product marketing at B2B SaaS companies, ideally enterprise.
- Proven track record creating marketing assets that directly impacted pipeline, win rates, or deal velocity.
- Experience building customer education programs or academies from scratch.
- Power user of AI tools like Claude, ChatGPT, Midjourney, Lovable, v0 to scale output and quality.
- Skilled at building custom AI workflows and prompts that enhance marketing productivity.
- Deep understanding of enterprise sales cycles and what sales teams need to close deals.
- Highly execution-focused with bias toward shipping fast and iterating based on feedback.
- Data-driven approach to measuring what works and doubling down on high-impact activities.
Bonus Points
- Experience marketing AI, automation, or customer experience products.
- Background in competitive intelligence and creating materials that win competitive deals.
- Brought customer training programs, online academies, or certification systems to life.
- Familiarity with sales enablement tools and CRM systems to track asset impact.
- Experience with no-code/low-code tools for landing pages, calculators, or interactive experiences.
Do Not Apply If
- You want to stay strictly within a defined scope. Product marketing is ever-evolving and requires tackling different projects that impact revenue and retention across the entire customer lifecycle.
- You need extensive team resources or agencies to execute. This role requires scrappy, hands-on execution using AI tools to scale yourself.
- You prefer brand marketing over performance-driven work. Everything ties back to pipeline, win rates, and revenue.
- You’re not comfortable with ambiguity. We’re building this function from scratch.
Why Siena?
- 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.
Our values
The people who thrive here are curious, customer-obsessed, and take ownership without being asked. They fix problems first and explain later. They’re direct about feedback—both giving and receiving it—because they care more about getting things right than being polite. They maintain high standards while moving at startup speed, and they build real relationships with teammates because they know that’s how great work gets done. When things get tough, they adapt and keep pushing forward.
Our approach to AI
The people who thrive here treat AI like a natural extension of themselves. They’ve built their own ecosystem of agents—some for research, others for debugging, writing, analysis, or writing code. They know which AI works best for what problem. Everyone gets premium accounts (ChatGPT, Claude, Perplexity Pro, Cursor, Lovable) plus a quarterly budget for new tools. The magic happens in how we share knowledge: demo days where someone shows off a clever workflow, Slack threads about which model handles a specific use case better, learning from each other’s AI workflows.
Siena provides equal employment opportunities to all employees and applicants for employment without regard to race, color, religion, sex, national origin, age, disability, genetics, sexual orientation, gender identity, or gender expression. We are committed to a diverse and inclusive workforce and welcome people from all backgrounds, experiences, perspectives, and abilities.
