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.

If you want to set the bar rather than follow one, keep reading.

The Role

As a Forward Deployed Product Manager, Agents, you're embedded directly with strategic accounts, owning their deployment outcomes end to end while feeding insights back into the platform. You're the person on the ground who deploys agents, drives automation rates, and turns what you learn into product improvements that scale across every customer.

You're energised by the loop: deploy agents, drive outcomes, identify gaps, build platform improvements, repeat.

What You'll Do

• Own AI agent outcomes for strategic accounts end to end: automation rates, resolution rates, time-to-value

• Deploy agents, identify what's blocking progress, then build the platform fix so the next account benefits

• Work directly with enterprise CX leaders to design and execute AI transformation roadmaps

• Turn deployment insights into platform capabilities: what you learn in the field shapes what we build next

• Build and improve agent capabilities that work across platforms: support, shopping, reviews, voice, social

• Design evaluation systems: QA suites, automated testing, performance monitoring

• Run full launch cycles from internal testing to GA, including customer enablement, demos, and co-selling alongside sales

Who You Are

The Bar: If you're missing any of these, this isn't the role for you.

• 5+ years in PM, solutions engineering, forward deployment, or technical account ownership

• AI-native mindset: you live in Claude, Cursor, and build your own workflows before anyone asks

• You can scope webhooks, OAuth flows, and complex integrations without needing an engineer to translate

Strong Signal: Not dealbreakers, but what separates a good hire from a great one.

• You've lived the problems customers are trying to solve: you know what great CX looks like from the inside

• You can diagnose whether a deployment problem is technical, operational, or stakeholder-driven, and prioritise accordingly

• You're comfortable advising CX leaders on organisational design, process optimisation, and transformation strategy

• You ship features, write docs, run demos, and measure what matters

Not a Fit If:

• You want to stay behind a roadmap and hand off execution to someone else

• You need an engineer to translate technical requirements before you can scope them

• You're more comfortable synthesizing feedback than living in the account day to day

Why Siena?

Real ownership. You will 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.

Great salary plus equity or stock grants. Own a piece of what you build.

Learning budget. If you are growing, so are we.

AI-fluency by default. Few places will push your work with production AI further or faster.

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.
