Frontend Tech Lead

Guardio is one of the fastest-growing companies in consumer cybersecurity - we’ve doubled revenue four years running, passed $150 million in ARR, and now protect over a million people, at a moment when AI has made scams more convincing than ever.

AI has democratized cybercrime: scams that once required sophisticated hacking teams are now cheap, personalized, and everywhere.

Traditional security wasn’t built for this - so we’re building it, protection that sees the person, connects all the dots - and stop attacks and scams wherever vector they come from.

And honestly, we all feel here - it’s just the beginning!

So, what's the job?

Guardio's frontend runs in four places: a browser extension, a web app, a mobile app, and the growth funnel. Four surfaces, four teams, one user who never sees the seams.

We're looking for a Frontend Tech Lead to own that craft across our frontend teams. You'll set the architecture, define the quality bar, and write the code on the hardest problems yourself.

Not a generic fullstack role. Frontend is the discipline here, and you're the authority on it. Hands-on, no direct reports.

You will:

• Advance the frontend architecture across both web and mobile platforms.
• Define the quality bar and make it measurable. Performance budgets, testing strategy, and review standards that hold in the age of AI.
• Build the shared foundation. Design system, component library, and build tooling that every frontend engineer at Guardio works through.
• Take the hardest problems yourself. Remove bottlenecks, speed up infrastructure, solve that time-critical bug in prod.
• Make the engineers around you better through code review, design review, and mentoring across our teams.
• Push how far AI can take frontend work at Guardio, and build the agents, skills, and workflows that let a small group ship like a much larger one.

Sounds great! Am I the right fit?

We're looking for a specific kind of person.

• 5+ years in frontend engineering, with deep React and TypeScript. You've owned complex products from first design through production and kept them healthy afterwards.
• You've been a frontend tech lead before. You owned the technical direction for a team, made the architecture calls, and set the standards. Formal management experience is not required.
• AI-pilled. You build with a coding agent every day, you've built your own workflows, and you know exactly where they break. In production, not in demos.
• You've built at consumer scale. Millions of users, real traffic, and a business that notices when a render path gets slower or a page stops converting.
