Full-Stack Mobile Engineer (React Native)
Pubblicato il 19-08-2026 - Blackboard Studio in Italia
About Blackboard Studio
Blackboard is a portfolio of AI-native consumer apps: we believe AI is reshaping how people use day-to-day software, and we’re leading the revolution.
We’re growing extremely fast (0 → €1M ARR in 10 months) with a small team of 8 incredibly talented young people (median age is 24!) who love to build and ship things.
We offer you a chance to build the AI apps of tomorrow, helping us scale from 1M to 10M users in the next 12 months.
We started by launching the now leading education app in Italy: Kiwi AI. Now used by 1M+ students worldwide!
We’re now expanding across Europe and launching 2 more apps before the end of the year.
About the role
You’ll be our 3rd engineer in the mobile team of Kiwi AI.
You’ll work directly with the founder, product, and growth team across the whole app: mobile development, architecture, AI, performance, UX, and improving product KPIs.
After an initial period on Kiwi AI, you’ll be able to decide whenever to keep scaling Kiwi AI to tens of millions of users across Europe or to jump into the 0 to 1 of one of our upcoming products.
The bar for talent at Blackboard Studio is extremely high, and we intend to keep it this way.
Our work environment is made for people who actually want to be the best at what they’re already good at. Because of this, you’ll be held accountable to improve your craft over the years.
For a talented, driven, and collaborative individual, working at Blackboard Studio is an opportunity to learn, make an impact, and progress their career at an exceptionally high rate.
Why this role matters
Engineering at Kiwi AI is not just about implementing tickets. You’ll have full ownership over product decisions and direct opportunities to impact the product’s growth.
You will
- Own the iOS mobile product experience, from development to the App Store
- Build beautiful, fluid, interactive experiences that feel magical
- Work directly with the founder and product lead to shape product direction
- Push the limits of what it means to build magical AI experiences
- Set the technical and product standards for our mobile app and the future product team
What you’ll work on
You will own the full product lifecycle, including:
- Turning Kiwi AI from just a “summary” tool to a complete platform where students can learn efficiently
- Own the full learning workflow in-app, creating a Duolingo-style learning progression from the user’s uploaded material
- Developing our community classes-based product, including leaderboards and friends activities
- Developing our public document-sharing product, which will let users find readily available materials from their classes, which turn into interactive lessons
More generally
- Build and ship features from concept to production
- Work with our product and design team to define roadmaps and product direction
- Create beautiful UX and AI workflows
- Test ruthlessly and catch bugs before users do
- Trace issues through the stack when they slip through
- Use AI tools to move faster and explore ideas
Who we’re looking for
- You are based in or near Milan, or open to relocating
- You have 2+ years of mobile development experience with React Native (Expo)
- You’re experienced in both React Native (required) and Swift (optional)
- You are a mobile-freak and have shipped your own apps
- You value craft and taste over everything, obsessing over every pixel
- You like going deep into a problem and thinking in first principles. You go the extra mile to speak with users, run tests and propose the best solution possible to the problem
- You don’t stop at the UI, you dive deep into product-related aspects (UX, KPIs, business metrics, roadmap)
- You thrive in a high-ownership and dynamic startup environment
Mobile craft & performance
You care about how the product feels.
You understand that in a consumer product, the difference between “good” and “magical” can be the difference between a user who churns and one who tells all their friends.
You likely
- Notice slow screens / interactions
- Love going above and beyond with details and animations
- Fix a bug as soon as you see it
- Can debug issues across iOS, React Native, networking, and backend systems when needed
Product & ownership mindset
You are not here to wait for tickets.
You will work directly with the founder and product team to understand user problems, scope solutions, make product decisions, build the feature, test it, ship it, run A/B tests and watch millions of real users use it.
You likely
- Move fast without needing heavy overhead
- Ask sharp product questions
- Care about activation, conversion, user progress and retention
- Take responsibility for outcomes, not just code
- Want to build something from the ground up
- Speed and reliability are not tradeoffs for you. They are both the standard.
AI-Native engineering
We move quickly and expect engineers to use modern tools aggressively.
You should already be using AI tools in your daily workflows and thinking seriously about what engineering will look like over the next few years.
Expected tools include
- Codex
- Claude Code
- Custom AI agents
The kind of engineer who thrives at Blackboard We’re not looking for just an engineer, but a well-rounded product person.
You likely

- Want meaningful ownership in an early-stage company
