• Rapid growth: Doubling ARR every few months, expanding our product surface, and rapidly building our team across Sydney, San Francisco, Melbourne, and New York.

• Well-resourced: $45m+ raised from the likes of Blackbird, Touring Capital, Hubspot Ventures, and Square Peg - we’re continuously investing in the people and tools that fuel our mission.

• A rare moment to join: We’re hitting an inflection point - big enough to have momentum, small enough for you to shape the journey.

• Customers love it: 140k+ reviews and a 4.9/5 rating on the App Store - people around the world rely on Blinq to make that first interaction count.

• We work in person, on purpose: We believe creativity and energy are better face-to-face - so we spend 3 days a week in the office and the rest where you work best.

Our engineering team is the engine behind Blinq’s success. We’re building tools that make sharing who you are instant and human. Every line of code, every release, and every experiment is focused on driving meaningful impact. If you thrive on solving complex, high-impact problems with a tight-knit team, you’ll feel right at home here.

As a Senior Full Stack Engineer at Blinq, you’ll build and maintain the APIs and services powering everything from identity sharing to real-time analytics. You’ll design systems that scale, contribute to architectural decisions, and ensure performance, reliability, and clean abstraction across our platform.
