## Description

As a Sofrtware Engineer at Ketch, you'll build the product surfaces that make massive, messy data ecosystems feel understandable and controllable. Our backend and AI systems classify sensitive data, detect issues across hundreds of technologies, and make real-time policy decisions. Your job is to turn this firehose of signals, metadata, and model outputs into interfaces that feel fast, obvious, and trustworthy.

You'll design workflows that help customers inspect systems, explore classification results, understand why decisions were made, evaluate risk, and take action. This role sits at the intersection of distributed systems, AI insights, and human decision-making: you're giving users clarity in environments that are inherently complex.

What You'll Own

 * Build the interfaces where customers map their entire data ecosystem and see how information moves across systems.
 * Create React experiences that surface real-time classifications, consent states, policy outcomes, and risk signals.
 * Craft experiences that bring "privacy by design" to life and are seen by millions of users every day.
 * Turn AI insights, model explanations, and decision traces into UI that feels obvious and trustworthy.
 * Build inspection tools that reveal where sensitive data appears, why the system flagged it, and what action to take next.
 * Work hand in hand with designers to craft reusable components and data patterns that stay reliable across streaming events, large datasets, and complex async flows.
 * Partner with backend and AI teams to shape the data contracts powering classification, system discovery, and automated governance.
 * Elevate our design system with patterns that make advanced privacy and governance concepts feel simple.
