Job description
Full-time · Remote · Australia or California · US$140k a year
Nobody rehearses a speech at a desk. They do it pacing the kitchen, in the car, in ahotel room the night before. The softrun iPhone and Android app is where thathappens: record a take, get the transcript and the delivery measurements, run itpast the audience, fix the line, go again. The app exists and ships. You will ownit, and you will be the first engineer on it who is not the founder.
What you will do
Own the Flutter app end to end: architecture, releases, both stores, crash-free rate.
Make recording bulletproof. Long takes, interruptions, phone calls, low storage, background audio. A lost take is the worst thing the app can do.
Bring delivery metrics closer to the device. Pace, pauses and energy are measured server-side today; some of that belongs on the phone, live, while you speak.
Build the rehearsal loop. Cue cards, the audience reacting as you go, the next take. The web has some of this; the phone should have the best version.
Work the API. The app talks to an Express backend with a documented OpenAPI surface. You will change both sides when the app needs it.
Handle the store plumbing you cannot avoid: subscriptions and passes through App Store and Play billing, sign-in with Apple and Google, deep links.
What we are looking for
You have shipped a Flutter app to both stores and kept it alive through OS releases, and you can show it.
You have done real audio work on mobile: recording, formats, permissions, background modes, the odd platform channel into Swift or Kotlin.
You are comfortable in a Node.js backend and will fix the API rather than work around it.
You care about the feeling of the thing. Latency, gestures, what happens on a bad connection.
You can run a codebase alone, with reviews from a founder who reads every line.
Nice to have
In-app purchase and subscription experience on either store, especially the renewal and refund edge cases.
On-device ML or signal processing —anything that runs on the audio while it is being captured.
An interest in VR. We have a headset rehearsal mode, and the phone is its companion.
What the first three months look like
Month one: ship a release. Small, but yours, through both stores. Month two: therecording reliability work, with the metrics to prove it. Month three: the liverehearsal loop in beta, and a written plan for what the app is in a year.
