We leverage deep browser internals knowledge and AI to detect what otherwise goes unnoticed — or is simply too cumbersome to catch.
From identifying malicious JavaScript executions to preventing account takeovers and fraudulent account creations, we are building the next generation of defense against sophisticated web threats.
Our team is a highly specialized group of seasoned browser internals experts and real-time distributed systems engineers.
We are building the infrastructure required to process complex signals at scale, turning raw browser data into actionable security intelligence.
Backed by $7.
7M in pre-seed and seed funding, cside is already trusted by a diverse range of the world's largest brands.
Our technology protects massive universities, global fast-food chains, e-commerce giants, online entertainment platforms, payment providers, SaaS companies, crypto exchanges, and travel networks.
This role is fully remote within the United States.
While much of our team works remotely across the globe, we bring everyone together twice a year for offsites in tropical locations.
About the role:We're looking for a full-stack developer to help build the product surface of cside — the dashboard, APIs, and customer-facing tooling that turn billions of raw browser signals into something a security engineer can act on in seconds.
You'll work close to the data and close to the customer, shipping quickly against a genuinely hard technical problem.
What you will do:Build and ship features across the stack, from API endpoints to the dashboard our customers live in every dayDesign and implement APIs that serve high-volume, low-latency security telemetryWork with our real-time data pipeline to surface detections clearly, without drowning users in noiseTurn complex security signals into interfaces that make the right action obviousOwn features end to end: design, implement, test, ship, measure, iterate.
