The posting

Founding Mobile Engineer

San Francisco, CA — In Office Full-Time $120,000–$200,000/year 0–4 Years of Experience

About the Company

Our client is an early-stage consumer technology company building AI-powered products focused on music learning.

The team is small, fast-moving, and focused on building products that combine artificial intelligence with engaging consumer experiences.

About the Role

Our client is looking for a Founding Mobile Engineer to take ownership of its mobile experience from the ground up.

The current product is iOS-based, with Android planned next. This person will own the mobile codebase and help bring existing AI technology to mobile before moving into the development of a new AI-native learning experience.

This is a product-leaning full-stack role. While the primary focus will be mobile and frontend development, you'll also need to be comfortable working across the backend when required.

The team places a strong emphasis on product thinking, design intuition, speed, and creating polished user experiences.

What You'll Own

  • Build and own the mobile application from the ground up
  • Develop for iOS, with Android planned next
  • Work across core infrastructure including authentication, payments, databases, and APIs
  • Translate product specifications and designs into production code
  • Ship quickly and iterate based on user feedback and usage data
  • Own the mobile UX end to end
  • Help establish mobile engineering practices as the team grows
  • Work closely with engineering, design, and product

What We're Looking For

  • 0–4 years of experience
  • Product-oriented full-stack mobile development experience
  • Experience with React Native, Swift, Kotlin, or similar technologies
  • Experience with Next.js and Tailwind
  • Experience with backend-as-a-service platforms; Supabase is strongly preferred
  • Familiarity with authentication, payments, database design, and APIs
  • Strong product and design intuition
  • Strong first-principles problem solving
  • Ability to work independently and own the mobile product end to end
  • Comfortable working with modern development practices and AI coding tools
  • Strong ability to move quickly from specifications and designs to production

Nice to Have

  • Musical experience or a genuine passion for music
  • Familiarity with music data formats or music transcription
  • Game development or learning-software experience
  • A multidisciplinary background
  • Experience building polished consumer applications

Work Environment

  • In-office role in the San Francisco Bay Area
  • Fast-paced early-stage environment
  • Visa sponsorship available

Compensation & Benefits

Salary: $120,000–$200,000/year

Benefits include:

  • Medical, dental, vision, and life insurance
  • PTO
  • In-office gym
  • Meals and snacks in the office

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
