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.

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.

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, 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, building premium experiences.

What matters across all paths: you understand complex systems, ship fast, have high standards, and want to build AI agents that interact with millions of consumers.

• 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

• Building complex AI systems that get smarter over time
• Shipping new capabilities that change how shopping and CX happens online
• Seeing customers adopt what you built, create real value, and move business metrics

• Own product areas end-to-end in our AI agent ecosystem. Full‑cycle ownership—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. Build QA suites, automated testing, 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, 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
• Act as forward‑deployed PM—meeting customers onsite, breaking down enterprise workflows into features, scoping in real‑time, validating pain points, building prototypes, moving fast from insight to shipped product
