Job description

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 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.

Engineering at Blinq

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.

Role & Impact

As a Senior Site Reliability Engineer at Blinq, you'll help build and operate the platform that powers millions of first interactions. You'll partner closely with platform, backend and product engineers to design resilient systems, automate operations, and continuously improve reliability as we scale globally.

Beyond keeping the platform running, you'll play a key role in shaping how AI transforms engineering at Blinq - using AI to automate operational toil, improve developer productivity, strengthen incident response and build more autonomous infrastructure.

What You’ll Do

• Design, build and operate highly reliable infrastructure that scales with global growth.
• Define and own SLOs, SLAs and error budgets, partnering with engineering teams to improve platform reliability.
• Evolve our observability, incident response and on-call practices to minimise downtime and improve operational excellence.
• Own and continuously improve our CI/CD pipelines, deployment workflows and developer experience.
• Identify reliability bottlenecks and proactively eliminate manual operational work through automation and AI.
• Build internal tooling and AI-powered workflows that help engineers move faster while maintaining reliability and security.
• Lead cross-functional initiatives spanning platform, infrastructure and product engineering.
• Champion engineering best practices across reliability, scalability, security and performance.

What You’ll Bring

• 5 - 7 years of experience in Site Reliability Engineering, Platform Engineering, DevOps or Infrastructure Engineering
• Deep understanding of distributed systems, cloud infrastructure and operating production systems at scale
• Experience designing high-availability, fault-tolerant architectures.
• Strong experience with monitoring, observability, logging and incident management.
• Strong experience building CI/CD pipelines, infrastructure automation and containerised workloads.
• Experience with cloud platforms (GCP preferred)
• AI fluency - you actively use AI tools (e.g. Claude Code, Cursor, GitHub Copilot or similar) to automate workflows, accelerate engineering and improve operational efficiency. You're excited about applying AI to infrastructure, reliability and developer productivity
• A collaborative mindset with a passion for mentoring engineers and raising the technical bar.
• Strong ownership, excellent judgment and a relentless drive to continuously improve systems and processes.
