Product Manager - Siena

Meet Siena

Siena is the 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.

What We’re Looking For

You're a builder who thrives at the frontier of AI agents, customer experience, and ecommerce. We welcome multiple paths:

• The operator who wants to build — you've been a solutions engineer, implementation manager, technical account manager, or worked in customer success at technical startups. You've implemented complex systems, managed enterprise rollouts, and architected solutions.
• The technical PM — you've been shipping product at technical B2B companies—ideally in CX, helpdesk, ecommerce, marketing tools, or AI automation.
• The consumer-minded builder — you understand what makes products feel good to use. You think about user behavior, ecommerce, purchase patterns, and building premium experiences.

Requirements

• 3+ years in PM, solutions engineering, implementation, technical account management, customer success engineering, sales engineering, solutions consulting, or product ops
• Experience with technical products and enterprise customers
• AI-native mindset—you live in Claude, Cursor, v0, and often max out your daily LLM limits
• Technical fluency—you can scope webhook systems, OAuth flows, and complex integrations
• Builder mentality—you ship features, write docs, run demos, and measure what matters
• Customer confidence—you thrive talking with customers, running demos, and co-selling alongside sales

What You’ll Do

• Own product areas end-to-end in our AI agent ecosystem (from discovery to shipping to enabling customers and internal teams)
• Build new agent capabilities that work seamlessly across platforms
• Design and ship evaluation systems that make our agents continuously smarter (QA suites, automated testing, performance monitoring)
• Own platform automation and onboarding to help customers go live in days, not weeks
• Expand our integrations ecosystem by shipping new platforms and enterprise app requirements
• Run full launch cycles from internal testing to early access to GA, including customer enablement
• Demo your own products to customers and co-sell alongside sales
• Act as forward-deployed PM—meeting customers onsite, breaking down enterprise workflows into features, scoping in real-time, validating pain points, and building prototypes

How We Hire

1. Intro Call: Fill in a short form then jump on an intro call to discuss your experience building products and managing technical launches.
2. Case Study: Build a hands-on case study—vibe code a small AI feature with a live link and Loom walkthrough.
3. Interviews: Join us for a round of interviews to discuss your experience in more depth.
4. Trial Week: Work with us for a trial week on a real project. Ship something meaningful while experiencing our culture firsthand.

Why Siena?

• Real ownership: You will own problems, not tasks, with the autonomy to solve them your way.
• 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.
• A team that respects your judgment: Globally distributed, async-first, low bureaucracy.
• 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.
