Pairio is a native macOS app for real-time screen sharing, built for people who work together: founders, designers, developers, product people. Not another meeting tool, but a collaboration tool. You share your screen, your teammate draws on it, takes over your keyboard. One click to call, no link, no invite.
We have ambitious plans for where it goes next, and we need help getting there.
What you’ll work on
Pixel-perfect screen sharing. Keeping text crisp across capture, encode, transport, and rendering while balancing quality, frame rate, and responsiveness on real-world connections
One-click calling. Making it feel instant: presence, signaling, WebRTC negotiation, and seamless audio/video setup
Drawing on screen and remote control. Live annotations, cursor sharing, keyboard and mouse input mapped precisely across machines
Privacy. App masking, encrypted connections, and making sure users always control what they share
Performance. Reducing latency at every layer so collaboration feels like sitting next to each other
Testing. We ship with confidence, not crossed fingers
The Swift app talks to a Rails backend. Bonus points if you’re comfortable on both sides
Who you are
Deep experience building native macOS or iOS apps in Swift
You care about UX: how things feel, not just how they look
An eye for UI: smooth animations, crisp rendering, and pixel-perfect details
You’re excited about AI changing how we build software, and you still take pride in what you ship
You enjoy working in a small team where you own large parts of the product
You’re based in Europe. Remote is fine, but we value real overlap for pairing and quick conversations
The team
Four founders in Amsterdam with decades of experience building great products. We built a healthy, profitable business by making something useful. That’s it. No pitch decks, no runway anxiety, no permission needed.
We shape and build together, using Pairio every day to make Pairio better.
