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).

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.

Our stack:

• Next.js (React/Typescript), Zustand
• AI (vercel) SDK
• Tailwind/Shadcn
• Supabase
• Clickhouse
• Golang/Fly.io
• Mobile: Swift, Flutter, Expo, Android

Requires Bachelors degree or higher in Computer Science or similar fields.
