Talent Ops Specialist (FTC) in London

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 is 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: Hiring at Siena is ramping up, and you'll own the candidate's first experience of Siena end to end: triage, first screen, feedback, follow-through. You're accountable for the quality and experience of everyone who makes it through your part of the process, and the ones who don't. Recruiting here is owned, not handed off, so you'll stay close to the candidate, close to the Talent Ops Manager, and close to the tools that run the work.

What You'll Do:

• Own inbound triage and first-round screens across our highest-volume and highest-stakes roles.
• Get every candidate an answer, on time. This is the standard the function is built around.
• Run scheduling and logistics across a growing slate of live roles.
• Keep Ashby immaculate: pipelines, notes, and statuses always current. If it's not clean in Ashby, it didn't happen.
• Use AI in your workflow. Claude and tools like it aren't optional; you use them to run the work, not just draft an email.
• Pitch in on sourcing when volume calls for it, though outbound stays with the Talent Ops Manager.

Who You Are:

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

• Comfortable building real workflows with Claude or similar. This isn't optional here, it's how the job gets done.
• Time at a boutique agency, or a startup at Series A or earlier. You've worked without a playbook and you're comfortable building one.
• Experience sourcing, not just screening, when volume calls for it.

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

• You've played a key role in building fully distributed, global teams. You flag when something's off on your own rather than waiting for direction.
• You're comfortable checking on alignment rather than waiting for the next instruction, while still owning the outcome.
• Not afraid of cold calling, when time allows, picking up the phone to our top talent targets.

Nice to Have: Bonus, not required.

• Exposure to running multiple live, high-stakes roles at once.
• You know the eCommerce / B2B SaaS landscape.
• Have used Ashby, Metaview and Pin.com as a part of your recruiting stack.

Not a Fit If:

• You want a fully scoped queue and clear instructions before you'll act. This role runs on judgment, not a checklist.
• You think candidate feedback is optional once someone's a no.
• You want to skip the AI tooling and do things the old way because it's familiar.
• You need a manager checking your work daily to feel confident it's right.

The Deal: Six-month fixed-term contract, with potential to transition to a permanent role at the end of the term based on performance and business need.

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 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.

How we hire: 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.
