Indexed description

Helium is building Self-Improving Software: AI that automatically generates & tests new software experiences to lift revenue. We’re…

  • Talent-dense (8 people, 6 engineers, 75% ex-founders)
  • Well-funded ($6M from Google & Leaders from OpenAI)
  • Fast-growing (Serving tens of millions of AI experiences per day for top consumer companies).

AI has created a once-in-history opportunity, and we’re here to win, because of that…

  • 🔴 We work in-person in our SF office 6 days per week (Mon-Sat). 🔴

What You’ll Do

You’ll help build our platform to auto-generate mobile experiences. Specifically, you’ll be in charge of big chunks of our mobile SDKs.

  • Own the iOS/React Native mobile experience for Helium customers
  • Launch new features (e.g. remote onboarding experiences) to help our customers automate mobile optimization
  • Come up with new ways to improve SDK reliability, speed, and usability, and work directly with customers to get feedback and improve their experince.
  • Own documentation, Release maintenance, CI/CD, Testing, Google Play/Android billing
  • Wearing a lot more hats than listed above 👷.

What We’re Looking For

  • Keen problem solving skills: you are able to cut down ambiguous problems down to first principles and deliver a working solution.
  • Strong mobile eng foundation: You have plenty of experience building mobile apps on the App Store, and using SDKs (RevenueCat, Amplitude, Segment, Stripe, Firebase)
    • Experience working with Apple In-App purchases.
  • Owning features end to end: you’ll write your own PRDs/quick specs when necessary, and you test your features end to end to make sure they work and satisfy the requirements
  • Customer obsession: you think deeply about the devex of SDKs, you answer questions, jump on issues, and use customer feedback to build excellent products.
Nice To Haves

  • Experience working on mobile SDKs (release maintenance, docs, etc)
  • Experience with Flutter and Android app development
  • Experience with native modules/bridging logic
  • Experience working on open source, or non-mobile experiences
  • Experience working on mobile webview tech (if you’ve figured out a cool way to make Android webviews feel almost native, get in touch)
  • Experience working with mobile analytics tools (Amplitude, Segment, Statsig, etc)

Reasons This Role Might Not Be A Fit

  • You want to work 9-5
  • You avoid Cursor or AI coding tools.
  • You can only operate on well-written specs, or feel uncomfortable designing new experiences from scratch.
  • You don’t want to talk to customers.
