Software Developer (C#, Python, SQL)

As a Global Markets Software Developer within the APAC Global Markets & Risks IT team, you are a hands‑on developer in an agile & users facing squad, building and evolving mission‑critical applications for the Japan Global Markets business. You work directly with front office, sales, operations, finance and risk, designing and implementing robust solutions in C#, Python, Powershell and SQL across the full trade lifecycle, from front‑office workflows through post‑trade, settlement, accounting and regulatory reporting.

You will be primarily responsible for software design and development, owning applications and services that support Japan onshore‑booked flows and products.
