This isn’t a live role - yet.

We’re always looking to meet sharp humans who see the world a little differently and want to help us reimagine how people connect.

We’ll reach out when something opens up that matches your energy, your skills, and where we’re headed next.

What is Blinq?

Blinq is building the fastest, most intuitive way to share who you are and remember who you meet. What started as the world’s #1 digital business card is now the starting point for over 50 million new relationships a year - and growing at unicorn pace.

Our vision is to build the world’s intelligence layer for professional relationships - one that remembers for you, prompts when it matters, and keeps you in play. If that’s the kind of scale and ambition you want to be part of, you’re in the right place.

Why You’ll Love It Here

• 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.
