Python Developer – Trading Team

Well-reputed proprietary trading firm that builds its own trading technology and runs its own trading desks across a range of markets and asset classes are looking to a hire a talented junior-mid level python developer to be embedded in their core trading team as a dedicated engineer.

job is not building a single product - it is solving many problems of different sizes, helping traders use code effectively, and building the shared tools and foundations the desks need to grow into new products and markets. Your success is measured by what the desks can do, not by how much code you write yourself. Success looks like traders building confidently on what you have put in place, and a codebase that keeps pace with the business.

If you relish working in a small team, side by side with traders and other technical stakeholders, this role is for you!

What you will do:

• Work with traders to understand their problems and turn them into practical solutions, whether they want a tool built for them or help building it themselves
• Build and own shared tooling across the trading workflow: reference and market data processing, pricing and strategy configuration, trade analysis, reporting and monitoring
• Shape the desks' codebase into generic, configurable, well-tested components, and keep it in step with our trading platform as it evolves
• Champion good engineering practice, including testing, reproducible environments, source control and code review, and make the right approach the easy one

What we’re looking for:

• A bachelor’s degree in Computer Science or similar
• 2-6 years experience (either in or outside of finance)
• Strong Python. You write code that other people can read, test and extend.
• Real software engineering judgement: separating concerns, isolating side effects, designing configuration well, and deciding when to generalise and when not to.
• You have improved or migrated an existing messy codebase without stopping the people who depend on it.
• Clear written and spoken English. You can explain a technical trade-off to a trader in their terms, and a trader's problem to an engineer in theirs.
• Curiosity about markets and how trading actually works.

Nice to haves:

• Experience with ETFs, futures, or reference and market data pipelines.
• Experience reading or debugging C++ well enough to follow an interface or a bug across the boundary.
• You use AI coding tools confidently and critically. They make you faster and your work better, and you hold what they produce to the same standard as your own code.

This is a full-time role, based in Singapore. Compensaton is highly competitive and contingent on experience.
