Product Specialist - Siena

Meet Siena

Siena is the Agent of Record for CX, built for consumer brands like Spanx, FIGS, Brooklinen, and Grüns.

It runs as a connected multi-agent stack on top of a shared intelligence layer: agents that sell, support, listen, handle social and voice across the entire customer journey, turning every conversation into signal you can act on.

The Team

We are a small, fully distributed, global team. We have built leverage into how we work, which is what lets a team this size move at the speed we do.

We hire athletes. Everyone here owns real outcomes, defaults to writing over meetings, communicates with directness, and acts the moment they see something worth acting on. Low ego, high standards, fast clock.

The Role

As a Product Specialist at Siena, you become the resident expert on how our platform works end-to-end: how each agent behaves, and how they work together as one system. You own a defined product surface deeply, you diagnose it with authority, and you're the bridge between the customers using it and the PM shaping where it goes next.

You're T-shaped. You know the whole platform end-to-end, and you go deep on one or two agents that become your own. You learn the product cold (prompt engineering, config, deployment), and then you put that knowledge to work across a range of product activities. This is a versatile, hands-on, product-minded role, not a ticket-closing one. You'll work a support queue, but the point isn't the queue, it's what it teaches you about how the product behaves in the real world.

If you've ever sat close to a product, noticed something the roadmap was missing, and pushed to change it, this role is built for you. It's for someone who's excited to work across a variety of product-related activities and wants to grow into product management, product marketing, deployment, or agent deployments.

Who You Are

• Product-minded above all: You go outside your job description to champion change and influence what gets built.
• Analytical: You've taken themes across tickets or customer feedback and used them to push product or roadmap direction.
• Curious & Hands-on: Genuinely curious about how things work under the hood, happy to roll up your sleeves. You don't see a support queue as beneath you.
• Strong Communicator: A clear communicator who moves between technical and non-technical people without losing either.
• AI-native: You use AI tools to do real work at scale, and you reach for new ones without being asked.
• Location: Based in EMEA or North America for strong timezone crossover with the team.
• Bonus points: Experience working in e-commerce or DTC brands, social media or community management, or hands-on CX at scale.
• Nice to have: Hands-on with APIs, Shopify themes, prompt engineering, or user research.

What You'll Do

• Own a defined Siena product surface and become its resident expert.
• Learn the platform cold: how the agents behave, how they work together, prompt engineering, config, deployment.
• Diagnose agent behavior with authority: product, config, or customer setup.
• Run the feedback loop to the PM: turn the patterns you see across customers into clear, prioritized signal that shapes the roadmap.
• Own enablement: the docs, guides, and live-chat material that sit between too-technical and too-marketing.
• Run webinars and demos, support sales, and do the market research the team needs.
• Work the support queue on your surface, not as overflow, but as your direct line to how the product behaves.

Why Siena?

• Real ownership: Own problems, not tasks, with the autonomy to solve them your way and the trust to do it without a manager in your inbox.
• Work that ships and matters: What you build reaches real consumer brands fast.
• A category we are creating: The Agent of Record is new ground, with unsolved problems and cutting-edge models, not a crowded field to compete in.
• A team that respects your judgment: Globally distributed, async-first, low bureaucracy. We hire adults and treat you like one.
• Compensation: Great salary plus equity or stock grants.
• Learning budget: If you are growing, so are we.
• AI-fluency by default: Premium accounts (ChatGPT, Claude, Perplexity Pro, Cursor, Lovable) plus a quarterly budget for new tools.
