I joined as the lone India-based engineer on a global Front Office compliance team — everyone else senior, everyone else elsewhere. The work sat ahead of every trade: pre-trade checks, post-trade checks, the reporting that keeps a regulator satisfied and a fund manager honest. Nothing shipped that hadn't passed through what we built. A defect here wasn't a bug ticket. It was a call with people far more senior than me, and an answer that had to hold. I learned to stay still when the room wasn't, and that the tools mattered less than the reasons behind them.
