🌍 We’re making security suck less for developers. Security tools haven’t kept up with how software is built today. They interrupt teams, slow releases, and turn security into a bottleneck instead of a capability. We built Aikido to change that. Aikido builds developer-first security products that reduce real risk without getting in the way of shipping software. We focus on what actually matters and automate the rest. We’re taking on legacy security tools teams have been stuck with, and we’re winning. If you want to help us take market share and build products developers actually enjoy using, you’re in the right place. Founded in 2022 by third-time founders, Aikido has $85M in the bank and a long runway ahead. We’re building toward self-securing software. Join an all-star team. Take real ownership. Push boundaries. Build things that matter. As a full-stack developer, you’ll be working closely with the Noon team at Aikido. Noon is our new workforce security product, protecting people from AI-powered attacks such as phishing, malware and deepfakes. It brings together email protection, device protection, AI governance, and attack simulations and training in one platform. You’ll help build the core of it from an early stage.
