Senior Swift Engineer (Full-Time)

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.

• 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

• 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

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.
