About Blinq

Blinq is the AI contacts app for people who meet people.

We're on a mission to unlock the world's relationship potential. So much of what's possible in the world is locked inside relationships that never quite happen. A missed conversation, a forgotten follow-up, the right person at the wrong time. We're building so those chances aren't left to chance.

What started as the world's #1 digital business card is now used by 4 million professionals and at 93% of the Fortune 500. We've raised $45m from Blackbird, Square Peg, HubSpot Ventures, and Touring Capital.

Why join Blinq

• You want to be part of an AI-native company at an inflection point. Big enough to have real momentum, customers, and resources. Small enough that the work you do shapes where it goes from here.
• You want to do the best work of your life alongside people doing the same. We hold an unusually high bar for talent and we hire people who treat that as a feature, not a threat.
• You want to build something globally ambitious from a part of the world that doesn't always think this big. Our team is in Sydney, Melbourne, San Francisco, and New York, and we're betting that the next category-defining company in our space comes from Australia.
• You want to work in person, on purpose. Three days a week in the office, two wherever works for you. Creative energy and momentum compound face to face.

How we work

We've all joined Blinq to find out how good we really are. That shows up in how we work:

• We are professional optimists. We think what's possible first and let constraints come second.
• We hold an insanely high talent bar. A players only.
• We are obsessed with craft. The details are the thing, not the polish on top of it.
• We are truth obsessed. We say what's true even when it's uncomfortable, and we have the courage to pursue contrarian but correct bets.
• We do more with less. Calculated frugality and beautiful simplicity guide how we build.
• We are all here to genuinely do our life's best work.

• 5 years in an SRE, DevOps, or Infrastructure Engineering role with deep understanding of distributed systems
• Proven ability to scale systems in production environments, including experience with high-availability architectures
• Expertise in monitoring, logging, and alerting systems and a sharp eye for what matters
• Strong experience with CI/CD systems, containerisation, and cloud infrastructure (GCP and AWS preferred)
• Familiarity with defining and managing SLOs and SLAs across complex systems
• A collaborative, mentoring mindset — someone who thrives on unblocking and upskilling others
• A strong sense of ownership and a bias toward continuous improvement

What you get

• Equity and ownership. We're building something massive and we want you to share in the upside. Genuinely.
• Competitive salary and a real growth path. As Blinq grows, your role and compensation grow with it.
• Time to switch off. 20 days of annual leave plus a flexible policy for everything life throws at you beyond that.
• Good times, often. Team lunches, padel, games nights, Barry's sessions. We like hanging out and it shows.
• Regular catered lunch at some of our offices, plus an always-stocked snack bar.
