There's almost nothing online about this level at BCG X so I'm posting what I pieced together from my own process and two conversations with people already there. This is senior IC territory: 'Staff Engineer' or 'Principal Engineer' depending on sub-team.
What I was offered (Staff Engineer, NYC, January 2026):
Base: $230,000
Bonus: 25% target. At this level people described it as usually paying out at 20-25%, so effective cash of $276k-$287k if things go reasonably well.
Equity: $200k over 4 years ($50k/yr). 1-year cliff. They said there's also a refresh grant process at 2 years but gave no specifics on typical refresh size.
Sign-on: $20k. Repaid in full if I leave within 12 months, prorated months 12-24.
Total Year 1 all-in: around $327k. Without sign-on, $307k.
For comparison I turned down this offer. Had a competing offer at $360k TC from a late-stage tech company (different title, equivalent scope). BCG X countered once and got to $335k Year 1 by moving the bonus to a 27% target, but couldn't match on equity.
One secondhand data point: A friend at BCG X who's been there 2.5 years at Principal level said their current TC after a raise is roughly $310k base plus bonus, no equity refresh yet at time of conversation.
Observation: At staff and above, FAANG-equivalent compensation is a stretch from BCG X. They're competitive with well-funded startups and strong non-FAANG tech companies. If you're leveling down from an L6/L7 at a top company, the math is harder to make work unless the role itself is genuinely compelling.
