About k-ID

k-ID is the global leader in privacy-first compliance and age verification infrastructure. Recognized as one of TIME’s Best Inventions of 2025, named a Tech Pioneer by the World Economic Forum and a winner of Fast Company’s Next Big Things in Tech, we are building the Age Layer for the internet—the fundamental infrastructure that allows digital platforms to verify age and manage compliance globally without friction.

Our core platform, anchored by the Compliance Development Kit (CDK) and AgeKit, is the trusted engine for the world’s largest game publishers and digital ecosystems. We replace fragmented, manual compliance with a unified API that handles age verification, parental consent, and regulatory logic across 200+ markets. Backed by top-tier venture capital firms like a16z and Lightspeed, k-ID is entering a phase of growth to define the standard for global digital safety.

About The Role

As a Full Stack Engineer at k-ID, you will help build the web applications and product experiences that developers, families, and end users rely on to interact with our platform.

This is a hands-on engineering role for someone who is comfortable working across the stack and wants real ownership. You will work closely with product, design, legal, and engineering partners to ship high quality applications that are fast, reliable, and easy to use. You should be comfortable moving between frontend and backend work, contributing to technical design, and operating what you build in production.

We are looking for an engineer who can execute independently, make sound technical decisions, and thrive in an early stage environment where systems and processes are still taking shape.
