Data & Strategy Lead

The Data & Strategy Team reports directly to Cartesia's founders and shapes our models capabilities. We work alongside researchers to find where models break, through evals and direct customer conversations, and then fix them by sourcing high quality data. We're looking for people who bring technical depth, operational rigor, and high agency, who want to have a lot of impact.

As a Data & Strategy Lead , you'll have broad ownership and autonomy to shape one of the most important inputs to frontier AI models. You'll work across research, product, and go-to-market teams, make decisions with incomplete information, and build new processes from the ground up. If you enjoy solving ambiguous problems, learning quickly, and creating leverage through systems, you'll thrive in this role.

- Partner tightly with research and modeling teams to find where models fail, through evals and direct customer conversations.

- Design, source, and maintain the evals that define quality for our models. Ground them in observed customer failures, benchmark continuously against other systems, and turn the results into concrete data requirements.

- Establish new sources of human data to advance model performance, building collection pipelines from scratch, and own data quality from acquisition through delivery.

- Stay close to the research. Read papers, understand what datasets move which capabilities, and collaborate with the team on what data to collect next.

- Be commercially minded. Engage with customers, enable the GTM team, and drive revenue growth.

- 3-10 years of experience in high-ownership roles (e.g., founder, GM, or strategy/ops at a startup).

- Technical fluency with data and operations; SQL proficiency required.

- Holds themselves and other to a high bar, bias to action, and strong attention to detail.

- Low-ego, collaborative, and mission-driven, focused on team and company success.
