Backend Engineer

We're making security suck less for developers. Security tools haven't kept pace with modern software development. They interrupt teams, slow releases, and turn security into a bottleneck. Aikido is changing that. We build developer-first security products that reduce real risk without getting in the way of shipping software. We focus on what matters, automate the rest, and make security a capability, not a blocker. Founded in 2022 by third-time founders, Aikido has $85M in the bank and the runway to build for the long term. Following our acquisition of Root.io in June 2026, the team formed Agentic Factory: the business unit moving beyond vulnerability detection to automated remediation. We are looking for an Backend Engineer to build and own the systems that drive this. Responsibilities Write modular, testable, and efficient code using Golang, Javascript, PHP and other languages. Managing Argo pipelines in K8s and lambda deployments. Research complex optimization problems. Understand the fundamental design principles behind a scalable application. Really comfortable in a very entrepreneurial environment. Can think along with architectural and impactful decisions. Willing to learn new languages when the product requires it. Comfortable researching and tackling hard problems and algorithms (eg parsing with ASTs). Willing to experiment (and also willing to perhaps throw away some code) We are going fast and need experienced people that can hit the ground running with us. You need to be comfortable with the above mentioned languages and tech-stack. No stranger to implementing automated testing platforms and unit tests Fluent in English Nice to have Experience in cybersecurity: CVEs, containers, software supply chain security, or pentesting. Experience working with AI agents (Langfuse, Langchain, etc.) Experience with Go or TypeScript. What you can expect Short decision lines. Big ownership. Shape the projects that matter and ship fast. Grow as fast as we do. Take on more, own more, and carve out your own path. Top-tier tech pay and equity. High trust, strong values, zero corporate BS. Flexibility in working hours. A company that sticks to its values in an open and informal atmosphere. We hire for talent, drive, and potential. Everything else is noise.
