Meet Siena

Siena is the Agent of Record for consumer brands. One agent that owns the entire customer journey, running on a shared intelligence layer no point tool can replicate.

Consumer brands run ten or more disconnected tools to manage their customers. We collapse that stack into a single agent. It started with support, the hardest surface a brand has, and it expands from there: Shopping Agent, Social Agent, Siena working alongside a brand's own operators. One agent across every surface, with shared memory, shared context, and shared tools.

Hundreds of brands already run real customer volume on Siena in production. This is built, working, and growing, and we are racing to build what comes next.

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 own real problems rather than close tickets, keep reading.

The role

As a Technical Account Manager, AI Agent Deployment, you own both the technical and commercial health of your accounts. You master how Siena works under the hood to diagnose problems and drive outcomes - and you're commercially sharp enough to turn those outcomes into retention and growth.

You're not a pure CSM and you're not a support escalation point. You're the person customers trust to own their results, and who turns that trust into a longer, larger relationship.

Who you are

5+ years in technical account management, customer success engineering, or a hybrid technical/commercial role - SaaS, CX platforms, or e-commerce strongly preferred
Technically fluent: you understand how integrations work, can read a configuration, and can diagnose common deployment issues without escalating every time
You lead with outcomes - automation rates, resolution rates, and whether the account is actually working Commercially aware: you understand ARR, renewal risk, and expansion signals, and can position additional value without it feeling like a pitch
AI fluency - you use AI tools actively in your workflow and can enable and guide, confidently customers who are new to the space
You're proactive with data: you know what the numbers mean and you act on them before customers ask
You build relationships that outlast onboarding - customers want more access to you, not less
Remote

What you'll do

Own technical account health: diagnose automation performance issues, configure improvements, and drive resolution rates without always pulling in engineering
Be the primary point of contact for your accounts - customers know you by name and trust that you'll bring them clarity.
Run regular business reviews with customer stakeholders - bring data, tell the story, and drive clear next steps
Partner with the deployment team during onboarding to ensure the handoff is clean and the account is set up to succeed
Translate what you hear from customers into structured product feedback the team can act on

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.

We use AI-assisted screening tools as part of our hiring process. All decisions are made by humans. You can request a human-only review at talent@siena.cx.

Siena provides equal employment opportunities to all employees and applicants for employment without regard to race, color, religion, sex, national origin, age, disability, genetics, sexual orientation, gender identity, or gender expression.
