FWIW I switched from FAANG to trading last year and got a pretty big comp increase. I was entertaining an offer from another FAANG at the same time and it was still nothing compared to my offers in trading.
Won't give my current salary because this isn't anonymous, but my 2021 TC was ~150. Another FAANG offered ~200, and trading firms all offered numbers way higher.
That makes sense! I was giving early career ranges in Chicago in the mid-2010s (without factoring in bonus). NYC PropTrading salaries are (unsurprisingly) higher.
That said, mid-career (5-7 YoE) tech in the Bay Area at least reaches around $170-250k base with an additional $100-400k in stock+bonus over the 4 year vest.
Factoring in hours worked it seemed more competitive than around $200-300k TC for SWEs at the larger PropTrading firms in Chicago at least.
