Senior AI-Native Software Engineer – Full Stack (React, Next.js, Node.js)

We’re a software house with a team of 25 professionals distributed across three countries. We focus on long-term projects and believe great software comes from ownership, strong collaboration with clients, and developers who care about the quality and business impact of their work.

At the.good.code; successful software starts with understanding the business problem first. We work closely with our clients, use AI as an engineering tool rather than a shortcut, and improve the way software is designed and delivered. We focus on long-term collaboration and are looking for people who are curious, open-minded, and motivated to grow together with the business and the products we build.
