Product & Research Operations Manager, Voice Library

Our mission is to architect AI that learns from and interacts with the world like humans do.

We're pioneering the model architectures that will make this possible. Our founding team met as PhDs at the Stanford AI Lab, where we invented State Space Models or SSMs, a new primitive for training efficient, large-scale foundation models. Our team combines deep expertise in model innovation and systems engineering paired with a design-minded product engineering team to build and ship cutting edge models and experiences.

We're funded by leading investors at Index Ventures and Lightspeed Venture Partners, along with Factory, Conviction, A Star, General Catalyst, SV Angel, Databricks and others. We're fortunate to have the support of many amazing advisors, and 90+ angels across many industries, including the world's foremost experts in AI.

We are looking for a Product and Research Operations Manager to own, scale, and operate Cartesia's voice library. This role sits at the intersection of product operations, vendor management, and creative production, and directly impacts model quality, customer outcomes, and revenue. You will own the end-to-end library system: quality standards, gap analysis, sourcing strategy, procurement, bespoke enterprise delivery, and royalties.

You are building the voice ecosystem that powers our product, translating research insights and customer needs into a continually rising quality bar and partnering across research, product, GTM, and customer-facing teams to deliver voices that win in the real world.

• Own library health and quality: audit the existing library, remediate issues, and build the quality bar, recurring audit cadence, and issue-reporting workflows that keep standards high as the library grows

• Build systems to measure library gaps across use cases, personas, and locales, then design and execute a sourcing strategy to fill them

• Run formal procurement processes end to end, from proposal formation and benchmarking through negotiation and SLAs, expanding our vendor ecosystem beyond current channels

• Build scalable voice production pipelines in partnership with our voice production team, translating applied research insights into a continually rising quality bar

• Own bespoke voice sourcing for enterprise customers: source, produce, and deliver custom voices with clear SLAs, working with GTM and CS to turn them into reference wins and expansion revenue

• Make the library discoverable for GTM and CS through recommendation tooling and self-serve collateral

• Own voice royalties and payouts, including talent payments, tracking, and auditable documentation, in partnership with Finance and Legal

• 5+ years in operations, management consulting, or product at a high-growth technology or AI company

• You've stood up a function or program from scratch and turned ambiguity into repeatable process

• Strong vendor and contractor management experience across sourcing, scoping, SLAs, and quality oversight

• High autonomy and a bias toward shipping; you own problems end to end from insight through execution

• Strong cross-functional communication; you can influence without authority across Research, Product, GTM, and CS

• Sound voice and audio judgment; you can assess quality and accent correctness and articulate what separates a bar-raising voice from a generic one

• Comfort building lightweight tooling and using AI tools to scale operations without linear headcount growth

• Experience with audio, speech, or voice technology

• Experience running marketplace, catalog, or data operations programs

• Founder experience
