Product Engineer Intern
About The Position
As part of our early talent program, Cartesia is hiring a Product Engineer Intern to ship high-impact, model-powered experiences across Cartesia’s surfaces—marketing site, onboarding flows, self-serve funnels, dashboards, docs, and APIs—in close collaboration with our GTM, model serving, research, and product teams. You’ll work end-to-end across the stack to build, iterate on, and measure developer-first product experiences that drive activation, retention, and revenue. As a Cartesia intern, you’ll ship to production, own meaningful pieces of the product, and see your work directly impact Cartesia’s growth.
Requirements
- Currently pursuing a degree in Computer Science, Engineering, or a related field, with at least one previous internship or substantial project experience in software development.
- Proficient in TypeScript, with experience building modern web applications using React or a similar framework.
- Comfortable working across the stack; some backend experience in Python or Go with a focus on APIs.
- Evidence of shipping and iterating on a user-facing product in a fast-moving environment (internships, side projects, hackathons, open-source, or startup experience).
- Deep intuition for what makes a great developer experience—clear docs, intuitive APIs, and fast, reliable interfaces.
- Curiosity about product metrics and experimentation; you’re excited to use data and user feedback to guide what you build.
- You’re a little unhinged.
Nice To Haves
- Experience building or instrumenting growth surfaces such as sign-up flows, pricing pages, dashboards, or docs.
- Familiarity with analytics and experimentation concepts (e.g., event tracking, A/B testing, funnels).
- Experience building voice agents or voice-enabled applications.
- Active online presence on X/Twitter, LinkedIn, or a personal blog showcasing projects, writing, or developer-focused work.
Responsibilities
- Ship developer-first growth surfaces by combining user insights, data, and first-principles thinking.
- Bring Cartesia’s latest models to market by rapidly building high-performance interfaces and flows that help users discover, evaluate, and adopt them.
- Instrument and analyze key metrics (e.g., sign-up → first call, time-to-first-production-use, feature adoption) and iterate based on real user behavior.
- Communicate publicly about your work via Cartesia’s official channels as well as your own profiles.
- Collaborate cross-functionally with GTM, model serving, research, and product to craft surfaces that grow Cartesia and multiply our work.
- Help identify and reduce friction across the user journey—from first touch on the website to successful integration in production.
