Siena is building the first intelligence layer for customer experience - an AI‑driven operating system where agents learn, remember, and act across every customer touchpoint. Our technology goes far beyond support automation: it powers shopping agents, builds persistent customer memory, generates business insights, and creates human‑like, empathetic interactions.
Siena is a small (around 47 people), distributed team that works quickly and takes full ownership. If you’re driven by building the future rather than following a playbook, Siena will feel like the right place for you.
Together, we’re looking for a Talent & Operations Manager who will play a foundational role in shaping how Siena grows.
You will build Siena’s talent function from the ground up and lead hiring as we scale through Series A. You’ll work directly with founders to define hiring strategy, design processes, and ensure every hire is the right one at the right time. This role blends strategy and execution - you own both.
Lead full‑cycle recruiting across engineering, product, operations, GTM, and leadership roles
Own the entire talent function: strategy, systems, execution, outcomes
Build the hiring plan with founders and translate business priorities into a recruiting roadmap
Design scalable recruiting infrastructure: scorecards, interview loops, analytics, documentation
Source and engage passive candidates for senior and hard‑to‑fill roles
Manage external recruiting partners when needed
Build AI‑powered hiring systems (intake agents, AI screeners, automated workflows)
7+ years in talent acquisition, including as the first/solo talent hire in a scaling startup
Experience building or rebuilding a talent function end‑to‑end
Proven ability to source and close roles from senior ICs to C‑suite
Experience hiring internationally across time zones and distributed teams
Systems thinker with strong process‑design skills
AI‑native operator - you build AI systems, not just use AI tools
Comfortable working in a pre‑Series A environment where structure is still being created
You may not thrive here if:
you’ve only worked within fully built‑out talent organizations,
ambiguity or lack of structure slows you down,
hands‑on recruiting hasn’t been part of your work in the last two years.
Globally distributed team working at the frontier of CX and AI
Competitive salary + equity
Learning budget and a culture of continuous growth
Opportunity to solve problems that will define the future of customer experience
