Guardio is on a mission to redefine consumer cybersecurity for the modern internet.

We operate at consumer scale, protecting millions of people every day across devices, accounts, and digital touchpoints. In a world where phishing, fraud, and AI-powered scams evolve overnight, Guardio stays ahead of the curve.

We move fast, think deeply, and build with purpose. Our culture is rooted in transparency, feedback, and collaboration along with shared wins, team dinners, company trips, and good times.

We're a team of 100+ makers, doers, and boundary-breakers. If you're ready to tackle meaningful challenges, grow at lightning speed, and help shape the next frontier of online safety, you belong here.

Let's cut to the chase. What's the job?

You will:

  • Build and scale Guardio's internal systems for configuration, analytics, and experimentation

  • Design intuitive, high-utility UIs that help teams make data-driven decisions and move faster
  • Own projects from concept to production with a focus on reliability, performance, and usability
  • Integrate AI capabilities and continuously optimize internal tools for efficiency and impact

Sounds great Am I the right fit?

You might be, if you:

  • Have 5+ years as a Fullstack Developer working on complex, data-heavy systems
  • Are fluent in TypeScript, React, and Python, and comfortable leading across the stack
  • Have a strong sense for UI and UX, and care about building tools people love to use

  • Know your way around MySQL, Redis, BigQuery, and cloud environments like GCP and Kubernetes
  • Have worked with shadcn/ui, PostHog, or AI integrations (bonus points)
  • Thrive on collaboration and take pride in making your colleagues' work easier, better, and faster
  • Are proactive, pragmatic, and enjoy shipping high-quality, high-impact systems

Talk nerdy to me.
