Effective communication is key to translating business requirements into reliable backend solutions and maintaining smooth workflows across the team.

What does a Backend Engineer Java do?

A Backend Engineer Java is responsible for developing and maintaining the server-side logic, databases, and application programming interfaces (APIs) using the Java programming language. They ensure that the backend of web applications or software systems is efficient, secure, and scalable. Their work often involves collaborating with frontend developers, designing system architecture, and optimizing performance to handle large volumes of user requests. Backend Java engineers often use frameworks such as Spring or Hibernate and work with databases like MySQL or PostgreSQL.

What is the difference between Backend Engineer Java vs Backend Developer Java?

About the Project

Outlier helps the world’s most innovative companies improve their AI agents by providing human feedback. Do you want to shape the future of autonomous agents like OpenClaw?

We collaborate with leading AI organizations to train Large Language Models (LLMs) to function as proactive, multi-step agents. Our projects focus on teaching these systems how to design, coordinate, and optimize complex, real-world architectural workflows.

Whether you are a passionate orchestration guru or experienced software developer — we want you to help us train the world's most advanced generative systems.

Ideal Qualifications

  • 2+ years of experience in backend engineering, AI automation, or complex systems integration.
  • Proven ability to build and maintain production-grade software with modular separation (e.g., distinct services for data parsing, logic processing, and reporting).
  • Strong command of at least two major languages (e.g., Python, JavaScript, Go, or Java) and experience working with SQL databases.
  • Practical experience building for live, non-mocked environments and handling multi-turn system interactions.
  • 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.
  • Hands-on experience integrating agents with live tools such as Supabase, Gmail, and various APIs to solve real-world problems.
  • High level of comfort implementing persistent state and session discovery using MEMORY.md to track agent progress.
  • Experience identifying subtle failures like privacy leaks, authority escalation, or indirect prompt injections.
