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.
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.
עיקרי התפקיד
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.
You care about craft. UX, accessibility, and polish show up in what you've shipped, and you can explain why a screen feels right.
You're great to work with. You communicate clearly, argue with evidence, own your mistakes, and bring real energy without the ego.
Talk nerdy to me.
Don't mind if we do. Our tech stack:
Client: React and React Native in TypeScript
Backend: Python + Go
Cloud: Google Cloud on Kubernetes (GKE)
Data and experimentation: BigQuery, MySQL, Clickhouse, Redis, and our in-house A/B platform
AI tooling: Claude Code with an internal plugin marketplace of skills, MCP servers, and CLIs
