Why West CodeWest Code builds engineering teams around ownership and strong technical delivery, not just individual roles. We are developing a dedicated business unit focused on technology projects for banks, investment firms and other financial-services organisations. These are projects where understanding the business domain can matter as much as knowing the technology. You’ll work in senior environments on systems tied directly to trading, risk and financial decision-making, with strong technical ownership rather than purely ticket-driven delivery. If you have serious engineering experience in financial markets or risk technology, apply and let’s talk.
