Full job description

London (on-site) | WES Group

Fluent Mandarin Chinese and English are required for this role. You will work every day with our Mandarin-speaking team, clients and platforms. Please only apply if you can work professionally in both languages.

ABOUT WES GROUP

WES Group is a UK-registered company based in London and a licensed UK Skilled Worker visa sponsor. We work with clients across quant trading, fintech and Web3, and our team builds with AI tools and multi-agent workflows every day.Our Founder and CEO, Alex Jin, was previously CMO of MultiBank Group, where he led marketing across 110 markets, and APAC President of Destek.

WHAT WE ARE DOING

We are building on-chain asset issuance and trading products alongside core trading systems. Our Web3 work includes wallet connectivity, smart contract interactions, on-chain transactions and the frontend and backend services that support them.As an intern, you will contribute to well-scoped features with mentorship across Web3 and application development. Our team uses AI tools and multi-agent workflows every day, and you will learn how to review, integrate and validate their outputs.

WHAT YOU WILL DO

  • Build Web3 application features involving wallets, smart contracts and on-chain transactions.
  • Help connect frontend interfaces and backend APIs with blockchain networks.
  • Work with blockchain data, transaction status and application error handling.
  • Use AI tools to understand code, implement features, investigate bugs and write tests.
  • Explore multi-agent development with mentorship and verify the combined results.

WHAT WE ARE LOOKING FOR

  • Professional fluency in Mandarin Chinese and English, spoken and written.
  • At least one working project you built yourself using AI coding tools, such as Codex, Claude Code or Cursor. You must be able to demonstrate it and explain your contribution.
  • Computing or programming knowledge, or a strong interest in building with AI demonstrated through personal projects and self-directed learning. A Computer Science degree is not required.
  • Working knowledge of at least one of JavaScript/TypeScript, Go or Rust, plus basic familiarity with Web3 concepts such as wallets, smart contracts and blockchain transactions.
  • Basic familiarity with Git, HTTP/REST APIs and databases. You can understand and modify AI-generated code, debug problems and test the results.
  • Curiosity, initiative and clear communication, with enthusiasm for exploring Web3 and taking responsibility for your work.

Experience with wallet integration, Solidity, Rust-based smart contracts, Web3 SDKs or multi-agent development is a plus. Coursework and small personal projects count; you do not need to know every technology listed.

WHY JOIN US:

A LONG-TERM ROLEWe are looking for people who want to grow with us long term, not a short placement.

  • The role starts with a 1–2 month trial period.
  • After a successful trial, you move into a salaried, long-term position.
  • As a licensed sponsor, we offer the opportunity of UK Skilled Worker visa sponsorship.
  • You will get hands-on experience with real trading and Web3 products, with mentorship and AI-native engineering practice.

Recent graduates are especially welcome.

LOCATION & START DATE

  • On-site at our London office.
  • Immediate start preferred; the successful candidate must be able to start by 16 November 2026.
  • Applications are reviewed on a rolling basis, and the role closes once filled.

HOW TO APPLY

Please submit your CV and at least one project you built using AI coding tools, with a runnable repository, live demo or short demonstration video.Briefly tell us:

  • What the project does and which parts you implemented yourself.
  • How you used AI tools or multi-agent workflows.
  • How you debugged, tested and verified the final result.

If you have built a Web3 project, include the wallet, smart contract or on-chain functionality you worked on.
