*Terms of employment / engagement shall be subject to contract and local applicable laws
 

What you'll do

  • Build and improve pieces of the agent runtime: intent routing, query rewrite, RAG/FAQ answering, tool/skill orchestration (L0–L6 loop).

  • Extend the Tool Server — add and optimize tools (web search, market data, report APIs), improve tool-call efficiency and output quality.
  • Strengthen evaluation: write eval datasets and harnesses, measure intent-routing accuracy and answer quality, catch regressions before release

  • Improve observability: traces, metrics, logging (Opik/Pinpoint), production dashboards and alerts.
    Fix bugs across the pipeline (routing, skill loading, guardrail false-triggers) and write integration tests with mock-LLM cassette replay.

Must-have

  • Solid Python and clean coding habits; comfortable in a real service codebase with CI, code review, and typing.

  • Understanding of LLM application basics — prompting, RAG, tool/function calling, or agent frameworks (from coursework, projects, or internships).

  • Able to reason about correctness and write tests; debug across async/services.
    Available for a sustained internship and eager to iterate quickly on feedback.

Nice-to-have

  • Experience with an agent framework (AgentScope / LangChain / LlamaIndex or similar).

  • Familiarity with vector search / embeddings, evaluation frameworks (Opik, ragas), or LLM observability.
    Exposure to Kafka, Redis/Lindorm, S3, config systems (Apollo), or Docker/K8s.

  • Interest in evaluation, guardrails/safety (prompt-attack defense), or latency/cost optimization.
    What you'll get
  • Ship real features into a production AI agent used across the app.

  • Mentorship from senior BE/DS/algo engineers; end-to-end ownership of scoped tasks.

  • Hands-on exposure to the full modern LLM-app stack: RAG, tool servers, evals, LLMOps.
Why Binance
• Shape the future with the world’s leading blockchain ecosystem
• Collaborate with world-class talent in a user-centric global organization with a flat structure
• Tackle unique, fast-paced projects with autonomy in an innovative environment
• Thrive in a results-driven workplace with opportunities for career growth and continuous learning
• Competitive salary and company benefits
• Work-from-home arrangement (the arrangement may vary depending on the work nature of the business team)

What does a back-end developer in Web3 do?

A back-end developer in web3 typically works on the server-side of a web application, using technologies that are specific to the decentralized web (also known as Web3-related)

This might involve building and maintaining the infrastructure that supports decentralized applications (dApps), or developing the underlying smart contracts and blockchain-based systems that power those dApps

In general, the goal of a back-end developer in web3 is to create the technologies and tools that enable users to interact with the decentralized web in a secure and seamless way.
