Meet Siena

Siena is the first intelligence layer for customer experience. We're creating 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

We're a small, distributed team that punches way above our weight. Every person here has outsized impact because we've 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. We're building agents that don't just respond to customers—they remember them, learn from every interaction, and connect experiences across channels.

What we’re looking for

You’re a builder who thrives at the frontier of AI agents, customer experience, and e-commerce.

We're looking for someone who can own critical domains in our AI agent ecosystem:. You’ll build new agent capabilities, deploy evals, build process, collaborate closely with other PMs and our CEO to create the infrastructure for the future of e-commerce and CX.

You have

• 3+a years of product management experience with technical B2B products, ideally CX, e-commerce or AI automation

• AI-native mindset—you live in Claude, Cursor, v0, and often max out your daily LLMs limits

• Technical fluency with APIs and integrations—you can scope webhook systems, OAuth flows, and complex third-party connections

• Curiosity and a builder mindset—you like to build things and continuously learn new things

• Full-cycle ownership mentality—you find opportunities, run projects, write docs, run demos, enable sales teams, and measure adoption

• Customer-facing confidence—you thrive talking with customers, running demos, and co-selling alongside the sales team

You thrive when

• Building complex AI systems

• Designing evaluation systems that automatically improve agent performance

• Shipping new capabilities that change how shopping happens online

• You get energized by not just shipping new capabilities, but seeing customers adopt them

What you’ll do

• You’ll be the third PM on a elite team building the future of customer experience and e-commerce. Think full-cycle ownership—from discovery to shipping to enabling customers and internal teams.

• Build new agent capabilities and create agents that work seamlessly across platforms.

• Design and ship evaluation systems that make our agents continuously smarter. Build QA suites, automated testing, and performance monitoring that catches issues before customers do.

• Own platform automation and onboarding to help customers go live in days, not weeks. Create AI tools that reduce manual implementation work.

• Expand our integrations ecosystem by shipping new platforms and enterprise app requirements. Make it easy for customers to connect their entire tech stack.

• Run full launch cycles from internal testing to early access to GA, including customer enablement through webinars, documentation, and training sessions.

• Demo your own products to customers and co-sell alongside sales. You’ll be known by name in our customer Slack communities as the PM who ships what they need.

How we hire

1. Fill in a short form then jump on an intro call where we’ll discuss your experience building products and managing technical launches.

2. Build a hands-on case study—vibe code a small AI feature with a live link and Loom walkthrough covering your approach.

3. Join us for a round of interviews to discuss your experience in more depth.

4. Work with us for a trial week on a real project. Ship something meaningful while experiencing our culture firsthand. We'll see how you work, you'll meet the team, and we'll both figure out if Siena feels right for you.

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. But the magic happens in how we share knowledge. Demo days where someone shows off a clever workflows. Slack threads about which model handles a specific use case better. Learning from each other's AI workflows.

At Siena, we’re not just looking for people who can do a job. We’re looking for people who want to break boundaries, create the future, and reshape industries. If that’s you, we look forward to your application.
