Founding Product Engineer - Build AI-Driven Practice App

Quippy; San Francisco (CA); On-site; USD 150,000 - 200,000; Full time

Job summary

Quippy is seeking a founding Product Engineer to work directly with the founder, own meaningful parts of the product, and decide what to build, how it works, and when it ships. You should enjoy thinking about why people use a product as much as how it’s built, turn vague problems into concrete experiences, and collaborate with design and engineering to bring features to production.

This fast-paced, hands-on founding role includes room to influence the roadmap as the company grows and equity

Qualifications

• Experience with React Native and Expo, or substantial mobile development experience and the ability to get productive in our stack quickly.
• Comfort building interfaces with navigation, forms, state management, and asynchronous data fetching.
• Experience integrating APIs and authentication, including handling loading states, failed requests, retries, and unreliable connections.
• Ability to debug across the interface, network requests, and application state. You can trace a problem to its cause and verify the fix.
• Good engineering habits around Git, code review, testing, and maintainable code. You test the experience on a device.
• Comfort instrumenting user behavior and using analytics to evaluate a feature after it ships.

Responsibilities

• Product features from the initial idea through prototyping, implementation, and release.
• Experiences across onboarding, conversation practice, feedback, and progression that help people find value and want to return.
• Turning a loosely defined problem into a concrete experience. Making decisions about the flow, interactions, and details along the way.
• Using AI tools to build and test ideas quickly, while understanding the code and checking that the result works.
• Working with design and engineering to bring features to production, including the edge cases, performance, and polish.
• Talking to users, watching where they struggle, and using funnels, retention data, and experiments to decide what to improve.
• Following through after launch: fixing problems, measuring results, and revisiting decisions when the evidence changes.
