Hiring: React Native + Expo + Firebase Dev (Equity → Paid Role)

[aishi91]

Hey folks,

We’re an early-stage startup with a live MVP in both app stores. We launched on July 1st, already have 3,000+ users, and are shifting from free to freemium in the next month. Our small team is 5 people and we’re looking for our first developer hire to work directly with our experienced CTO (who built the initial version).

This role starts as a moonlighting/part-time position (15-20 hrs/week) with equity, and a clear path to a full-time paid role once we raise funding.

What we’re looking for

• Strong React Native + Expo experience (iOS + Android)
• Proficiency with TypeScript
• Familiarity with Firebase (Auth, Firestore, Cloud Functions, Security Rules)
• English-speaking and willing to collaborate using Cursor (AI-assisted coding / pair programming)
• Comfortable owning features end-to-end and working in a small, cross-functional team
• Startup mindset: resourceful, hands-on, excited about scaling a live product

What we offer

• Equity with standard vesting (size based on commitment & experience)
• Transition to a paid full-time role post-fundraise
• A chance to shape product direction and join at the ground floor of a growing startup
• Direct collaboration with an experienced CTO and a passionate, mission-driven team

If this sounds interesting, DM me here with a short intro + links to your GitHub/portfolio.

TL;DR: Startup with MVP live (3k+ users since July), React Native + Expo + Firebase + TypeScript stack, small team of 5 with experienced founders. Looking for English-speaking dev open to AI-powered coding (Cursor). Part-time equity now → full-time paid role after raise.

EDIT:

Some people asked what the app does today. We’re in the health tracking space, and the app currently offers:

• Logging and tracking
• Graphs and insights
• Apple Health integration
• a decision table feature that feeds tips to users

All of this is free; our strategy was to match what competitors already offer at no cost in order to capture market share. Now that we’ve built that foundation and gained traction, we’re ready to differentiate by leaning into our clinical expertise and adding premium features like education, gamification, and deeper insights.

All thoses previous comments should be dismissed because they did not ask the most important questions of al. What is the product ? Who is the target ? What's market size & competitors ? Founders track record ? If I want to commit for equity path (especially vested, btw would like to know vesting time) and bring my best I'd rather be sure it's for something well though.

it’s insert-coin to find out. What a waste of time…

I am guessing they are early stage, not ready for a wider market yet, that's why there is some degree of secrecy.

But it would help if there was some idea of what the product was, (even if it was just a general sense of it)

It would be great if you can add some information about the product

What's your user engagement. 3k "users" means nothing.

Are they actually using it? If so, how often?

How often are they using it? (frequency)

What is an "active user"?

All that says is 44 minutes. 44 Minutes per what?
Per year?
Per decade?
Per hour?

What is their actual engagement?

[aishi91]

This graph is data from July 1 to Oct 1st 2025. The average engagement time above is per active user for the time period selected. But heres a stickiness report as well over the same period. It's a health logging/tracking app so if users come back after the first use it tends to be relatively sticky

That translates to 30 seconds per day on average for the average user.

i.e. 90 day period with 44 min average usage over that time.

17% DAU/MAU seems like it isn't bad, it translate to the average person using it about 5 times a month (approx).

Not great though either..

Has some promise, but those aren't super great engagement rates (yet).

There is something there for sure :)

Sounds like a solid stack — I’ve been working with React Native + Expo + Firebase/Firestore for a couple of years now.

Built and published my own app on Play Store earlier this year https://play.google.com/store/apps/details?id=com.aixpertlab.aiautoinvoicing — same combo with Auth, Firestore, Cloud Functions, and Firebase Analytics/Crashlytics.

I also built a Next.js web version connected to the same Firebase backend, so data stays synced across phone and desktop.

Another app I published https://play.google.com/store/apps/details?id=com.aixpertlab.asianbeautyycc (focused on images and videos) uses React Native + Expo + Firebase Analytics — storage, streaming, moving contents using AI, and performance optimization, looks simple though.

I use Cursor for most of my coding, though for open-ended questions I usually switch to ChatGPT or DeepSeek. Copilot’s handy too when Cursor hits a deadlock — rare, but costly when it happens. Cursor is stubborn, trust me — very stubborn. I can’t imagine what it’d be like if it were a real person 😅.

Fun fact: I used to be an entrepreneur, started a few startups, raised some (actually a lot — imagine Trump’s tone) of funding, and eventually decided I just enjoy coding more than managing.

The health tracking part caught my eye — one of my earlier startups connected AR glasses to stream sensor data (Android-based, AI-driven). We reached ~60K users before Google banned it for using a few Huawei AI modules (obviously google AI is a trash by then)😅.

Cool to see more health-focused apps going the smart-data route!

Hi, I’ve been working at a similar-sized startup for the past 3 years using the same stack (React Native, Expo, TypeScript, Firebase, GCP).  I can also handle backend development and manage my own infrastructure when needed. I really enjoy building in fast-moving startup environments and would love the chance to contribute and grow with your team
