Full-Stack Engineer

Role overview Build features across an AI-agent platform’s creation tools, runtime, and backend services. You’ll own work from early product ideas through production, including the APIs that connect agents with the external systems businesses use, and help keep the platform reliable as usage grows.

Responsibilities - Develop features across the agent builder, runtime, and backend services. - Design and maintain APIs that let agents read from and write to third-party tools. - Work with product and design to shape, ship, and measure features. - Improve platform performance, reliability, and observability. - Review code, write tests, and keep the codebase maintainable for a small team.

Requirements - At least three years of full-stack development experience; TypeScript, React, and Node.js are preferred. - Experience designing APIs and integrating external services. - Comfort working with relational databases and cloud infrastructure. - Regular use of AI coding tools, paired with sound judgment about their output. - Product awareness and care for the user experience of the features you build.

Nice to have - Experience with LLM applications, tool calling, or agent frameworks. - Background at an early-stage startup or developer tools company.

Benefits and work setup Remote contract role with flexible hours. Compensation starts at $4,000 per month.

Application exercise Build and publicly publish an agent for a real business using the provided free model. Connect it to an external API so it can perform at least one practical task, such as checking availability, order status, or a quote. Submit the agent link, code or repository, and a short explanation of the design, production considerations, and any platform limitations. There is no stated time limit.
