Salary: £73,000 - 94,000 per year Requirements: We require 2 years of experience in backend engineering, AI automation, or complex systems integration. We require proven ability to build and maintain production-grade software with modular separation, such as distinct services for data parsing, logic processing, and reporting. We require strong command of at least two major languages, such as Python, JavaScript, Go, or Java, and experience working with SQL databases. We require practical experience building for live, non-mocked environments and handling multi-turn system interactions. We require outstanding attention to detail and the ability to provide clear, high-density technical feedback on complex system behaviors. Nice to have: expertise building multi-stage coordination tasks where data acquisition leads to reasoned output. Nice to have: hands-on experience integrating agents with live tools such as Supabase, Gmail, and various APIs to solve real-world problems. Nice to have: high comfort implementing persistent state and session discovery using MEMORY.md to track agent progress. Nice to have: experience identifying subtle failures such as privacy leaks, authority escalation, or indirect prompt injections. Responsibilities: We will help train advanced generative systems by providing human feedback on AI agent behavior. We will collaborate with leading AI organizations to train large language models to function as proactive, multi-step agents. We will design, coordinate, and optimize complex, real-world architectural workflows. We will evaluate system behavior in live environments and provide high-density technical feedback. We will help improve agent performance by identifying subtle issues and failure modes. Technologies: AI Backend Java JavaScript Python SQL More: We are Outlier, and we help the worlds most innovative companies improve their AI agents through human feedback. Our projects focus on training large language models to function as proactive, multi-step agents and to design, coordinate, and optimize complex real-world workflows. We are looking for experienced builders and orchestration-minded developers who want to help shape the future of autonomous agents. last updated 21 week of 2026
