Core Banking Systems Specialist (Temenos / Mambu) roles score 40% on our remote-friendliness index (Moderate). This is because configuration and testing work is largely asynchronous, though core-banking migrations keep some phases on-site. Where in-office attendance is required, it is typically driven by go-live cutover weekends and regulator-facing testing sessions still pull Core Banking Specialists into a Mexico City office.

Quantitative Developer (C++ / Python) roles score 35% (Moderate). Modelling and backtesting work is largely independent and asynchronous, though trading-desk proximity keeps some roles hybrid is the primary driver of flexibility. When office days are required, it is usually for trading-desk collaboration and risk-committee reviews still pull Quant Developers into a Mexico City office, and banks formalize this into a fixed schedule.
