WES Group

AI Full-Stack Engineering Intern (Trading Systems / Web3, Mandarin Speaking)
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 core trading systems as well as on-chain asset issuance and trading products. As an intern, you will work on real scenarios, including market data, order processing, account management, wallet connectivity and on-chain transactions, with mentorship across frontend, backend and Web3 development.
Our team uses AI tools throughout development and hands suitable tasks to multiple agents running in parallel. You will learn how to review, integrate and validate their outputs.
WHAT YOU WILL DO
Deliver well-scoped product features and engineering tasks, taking part in development, testing and bug fixing.
Use AI tools to understand existing codebases, break down tasks, help with implementation and write tests.
Try multi-agent parallel development with mentorship, for example running separate agents for feature logic, tests or code checks, then combining the results.
Work with senior engineers to understand how a feature flows from the UI and API down to the database or on-chain interactions.
WHAT WE ARE LOOKING FOR
Fluent Mandarin Chinese and English, spoken and written (required).
Working knowledge of at least one of TypeScript/JavaScript, Go or Rust, and the ability to build and run a small working project on your own.
A basic understanding of Git, HTTP/REST APIs and databases, and keenness to learn full-stack development.
Basic familiarity with smart contracts or Web3. Coursework, hobby projects and personal repos all count.
Experience using AI coding assistants, and the ability to explain the code they generate and check it by running it and testing it.
Awareness of multi-agent workflows, or willingness to learn them. Experience on large projects is not required.
Curiosity about existing code, proactive communication and close attention to detail and testing.
WHY JOIN US: A LONG-TERM ROLE
We 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 &amp; START DATE
On-site at our London office.
Immediate start preferred; the successful candidate must be able to start by 2 November 2026.
Applications are reviewed on a rolling basis, and the role closes once filled.
HOW TO APPLY
Please submit your CV with a link to a runnable project or code repository, and briefly tell us:
Which parts of the code you wrote yourself.
How you used AI tools or multi-agent workflows.
How you checked and verified the final result.
