The ladder
How leveling works for backend engineers
Backend engineering pay scales tightly with level because the scope of what you own grows so visibly: an L3 ships within a service someone else designed, an L5 owns the design of a service, and an L7 owns the architecture of a platform that other teams build on. That widening blast radius is exactly what each level's pay band is buying.
The mid-to-senior jump is the one most backend engineers care about, because it is where total compensation starts to include real equity rather than a token grant. A senior backend offer at a top-tier company can carry an equity component as large as the entire base salary of a mid-level role, which is why the senior band below is so much wider than the mid band.
Specialisation matters too. Backend engineers who go deep on distributed systems, databases, or high-scale infrastructure tend to sit at the top of each band, because those skills are scarce and directly tied to revenue-critical systems. Generalist backend work clusters around the midpoint.
IC track
Individual-contributor pay by level
Total-compensation bands for the individual-contributor ladder in San Francisco. The midpoint is the typical offer for a calibrated candidate; the range spans company tier and negotiation outcomes. Senior and above fold in bonus and equity.
| Level | IC title | Experience | Total comp range | Midpoint | Basis |
|---|---|---|---|---|---|
| L3 | Entry / New grad | 0-2 yrs | $79,000$121,000 | $97,000 | Base |
| L4 | Mid-level | 2-5 yrs | $122,000$186,000 | $149,000 | Base |
| L5 | Senior | 5-8 yrs | $214,000$327,000 | $262,000 | Total comp |
| L6 | Staff | 8-12 yrs | $281,000$428,000 | $343,000 | Total comp |
| L7 | Principal | 12+ yrs | $458,000$719,000 | $533,000 | Total comp |

What each promotion is worth
- Moving from L3 (entry / new grad) to L4 (mid-level) lifts the median by about 54% in San Francisco, from $97,000 to $149,000.
- Moving from L4 (mid-level) to L5 (senior) lifts the median by about 76% in San Francisco, from $149,000 to $262,000.
- Moving from L5 (senior) to L6 (staff) lifts the median by about 31% in San Francisco, from $262,000 to $343,000.
- Moving from L6 (staff) to L7 (principal) lifts the median by about 55% in San Francisco, from $343,000 to $533,000.
- Across the full ladder, a principal (L7) backend engineer earns about 5.5x the entry (L3) midpoint, before individual negotiation and company-tier effects.

Management track
IC versus manager pay
Many senior backend engineers face the IC-vs-manager fork around L5. The pay is deliberately similar at that branch point so the choice is about the work, not the money; the bands only pull apart at director level, and even then a principal IC can out-earn a senior manager.
| Level | Title | IC equivalent | Total comp range | Midpoint |
|---|---|---|---|---|
| M1 | Engineering Manager | L5/L6 | $274,000$417,000 | $335,000 |
| M2 | Senior Manager | L6/L7 | $458,000$719,000 | $533,000 |
| M3 | Director | L7+ | $559,000$877,000 | $650,000 |
Translations
How the ladder maps to company levels
Every employer numbers its ladder differently, but the rungs line up. Here is how the standard L3-L7 ladder translates to the schemes you are most likely to meet when interviewing for backend engineer roles.
| Company | Entry → Principal |
|---|---|
| L3 / L4 / L5 / L6 / L7 | |
| Meta | E3 / E4 / E5 / E6 / E7 |
| Amazon | SDE I / SDE II / SDE III / Principal |
| Stripe | L1 / L2 / L3 / L4 / L5 |
Level translations are approximate. Companies calibrate scope differently, so the same code can mean slightly different things across employers.
How these bands are built
Each level band starts from the published percentile data for backend engineer roles in San Francisco. The four documented seniority tiers (junior, mid, senior, staff) are mapped onto the standard L3-L7 ladder: junior anchors L3, mid anchors L4, the senior tier spans L5 and L6 because in real ladders it is the widest band and covers two promotion steps, and the staff tier anchors L7. The low and high ends of each band come from the tier's 25th and 75th percentiles; the midpoint is the tier median.
Senior, staff, and principal bands are reported as total compensation, folding in bonus and equity, because that is how those levels are paid in practice. Entry and mid bands are base-heavy. The management track is anchored to the same tiers with the documented manager premium applied at the senior-manager and director levels.
Reference data only. Real offers vary by employer, level calibration, team, and negotiation, and frontier-lab pay can sit well above these bands. Nothing here is financial advice. Primary sources: US BLS OES May 2024 (SOC 15-1252) + Levels.fyi 2025 (2025).
