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