Job description

We are one of the world's earliest and most established digital asset platforms, serving tens of millions of users across global markets. Consistently ranked among the top exchanges worldwide, we support a comprehensive suite of trading and wealth management products across thousands of digital assets. With thousands of employees spanning key financial hubs globally, we operate with a remote-first, high-autonomy culture that attracts talent who thrive in fast-moving, intellectually demanding environments. We are building the financial infrastructure of the next era of the internet.

Why this role

Our products now reach users in dozens of markets, and the services behind them have to stay fast, correct and secure as volume and scope grow. Many of the teams who define those products work in Mandarin, and this role sits right next to them, so what they need reaches the code intact. You'll turn that into reliable backend services. In 18 months you'll own a meaningful part of our backend, have run it under real production load, and be the person other teams bring their hardest design questions to.

What you’ll do

• Design, build and ship backend services that handle high-volume, latency-sensitive traffic
• Own your services in production, from monitoring and incident response to the fixes that stop repeats
• Turn requirements from Mandarin-speaking product and engineering teams into clear technical designs, and document them in English for the wider team
• Raise the bar on code review, testing and documentation across the team
• Improve the performance and reliability of existing services, with results you can measure

What you’ll bring

• Has built and run backend services in production at scale, from design through on-call
• Writes clean, tested code and holds others’ code to the same standard
• Fluent in spoken and written Mandarin and English, since you'll work daily in both
• Turns an ambiguous requirement into a working design without waiting to be told how

Bonus

• Has worked on payments, trading or other financial systems
• Has worked in remote-first teams across time zones
