One of the most common mistakes engineering leaders make when planning headcount is working from outdated salary data. The engineering labour market moves fast. A compensation framework built in 2022 or even late 2023 can leave you making offers that are 10–20% below market — enough to lose great candidates to competitors who've kept their data current.
This guide outlines current software engineering salary benchmarks across key roles, levels, and geographies, and explains how to use benchmark data effectively when building compensation frameworks.
Why does salary benchmarking matter for engineering leaders?
Compensation benchmarking isn't just an HR exercise. For engineering leaders, it has direct implications for:
- Hiring success rate: Offers that land below the 50th percentile increasingly get rejected outright, especially at senior levels where candidates have multiple competing offers.
- Retention risk: Engineers who discover they're paid below market — which happens more often than you'd expect, given the volume of salary transparency on sites like Levels.fyi and Glassdoor — become flight risks.
- Budget accuracy: Modelling headcount growth on stale benchmarks means your financial projections will be wrong from day one.
- Equity within teams: Inconsistent benchmarking leads to pay disparities that become problems when they surface.
How do engineering salary levels and bands work?
Most mature engineering organisations define salary bands around levels or grades, not job titles. Common levelling frameworks look something like:
| Level | Typical Title | Years of Experience | |---|---|---| | L3 / IC3 | Junior / Associate Engineer | 0–2 years | | L4 / IC4 | Software Engineer | 2–5 years | | L5 / IC5 | Senior Software Engineer | 5–8 years | | L6 / IC6 | Staff Engineer | 8–12 years | | L7 / IC7 | Principal / Distinguished Engineer | 12+ years |
The key insight is that the jump from Senior to Staff is where total compensation packages diverge most dramatically — both in base and in equity component.
What are the software engineering salary benchmarks for the UK in 2025?
The following ranges represent the 25th–75th percentile for London and major UK tech hubs. Remote-first companies in the UK often pay London rates regardless of where candidates live.
| Role | 25th Percentile | Median | 75th Percentile | |---|---|---|---| | Junior Software Engineer | £35,000 | £42,000 | £50,000 | | Software Engineer (mid) | £55,000 | £65,000 | £75,000 | | Senior Software Engineer | £75,000 | £90,000 | £110,000 | | Staff Engineer | £100,000 | £120,000 | £145,000 | | Principal Engineer | £130,000 | £155,000 | £185,000 | | Engineering Manager | £85,000 | £105,000 | £130,000 |
Note: These figures represent base salary only and exclude equity, bonus, and benefits. London-based roles typically command a 10–20% premium over other UK cities.
What are the software engineering salary benchmarks for the US in 2025?
The US market is significantly higher than the UK, particularly for senior roles, and varies enormously by geography. San Francisco, New York, and Seattle sit at the high end; Austin, Denver, and remote roles trend lower.
| Role | 25th Percentile | Median | 75th Percentile | |---|---|---|---| | Junior Software Engineer | $85,000 | $100,000 | $120,000 | | Software Engineer (mid) | $120,000 | $145,000 | $170,000 | | Senior Software Engineer | $160,000 | $195,000 | $230,000 | | Staff Engineer | $210,000 | $255,000 | $310,000 | | Principal Engineer | $270,000 | $325,000 | $400,000 | | Engineering Manager | $175,000 | $215,000 | $265,000 |
Note: US figures are base salary. Total compensation (including equity and bonus) can be 1.5x–2.5x base at senior levels in high-growth companies.
Do specialist engineering roles command a salary premium?
Not all engineering roles command the same salary. Certain specialisms carry significant market premiums due to demand/supply imbalances:
- Machine Learning / AI Engineers: 15–30% premium over equivalent-level software engineers
- Security Engineers: 10–25% premium, especially at Staff+ levels
- Platform / Infrastructure Engineers: 10–20% premium for cloud-native expertise
- Mobile (iOS/Android): Largely on par with web engineers, slight discount at junior levels
- Frontend Engineers: Slight discount at junior/mid levels vs backend; converges at senior+
How does equity fit into engineering compensation?
At scaling tech companies, equity is increasingly a primary compensation lever — and one that candidates evaluate carefully. A £90k base + 0.1% options over four years is a very different offer to £85k base + 0.25% options, depending on your company's valuation trajectory.
For benchmarking purposes, it's useful to understand the equity norms at your stage:
- Seed-stage: Senior engineers typically receive 0.1–0.5% options; engineering leaders 0.5–2%
- Series A/B: Grants compress as valuation rises; senior engineers 0.05–0.2%
- Series C+: Equity amounts shrink further but company de-risking compensates
How do I build a compensation framework from benchmark data?
Once you have benchmark data, the next step is building a framework your organisation can operate consistently:
- Define levels clearly: Use a levelling matrix that distinguishes scope, impact, and technical complexity — not just years of experience.
- Set band widths deliberately: Bands should be wide enough to reward growth within a level (typically 20–30% wide).
- Decide where to anchor: Most competitive tech companies anchor at the 50th–75th percentile.
- Review annually at minimum: The market moved significantly between 2020 and 2023. Annual reviews protect you from drift.
Using TeamCalc for Benchmarking
TeamCalc provides current salary benchmarks by role, seniority, and location — integrated directly into your team cost model. Rather than maintaining a separate benchmarking spreadsheet alongside your headcount plan, you can see in real time whether your planned salaries are competitive, under-market, or above-market.
The benchmark upload feature (Pro and Growth plans) also lets you bring in your own internal salary data and compare it against market benchmarks — useful for compensation reviews and board presentations.
