Staff Software Engineer is IC5 in most leveling systems. It sits one rung above Senior and is the first level of senior technical leadership. Google calls it L6 and Meta calls it E6. Amazon has no Staff title, and its L7 Principal is the Staff equivalent.
Below is each rung from junior to Fellow, with the experience it usually takes and the scope it brings. Then come the company mappings and how long the climb takes.

Software engineer levels at a glance
Engineering levels vary by company, but most follow a similar structure. Here’s the typical progression from entry level to the most senior technical roles.
| Level | Title | Experience | Scope |
|---|---|---|---|
| IC1-IC2 | Junior Engineer / Engineer I | 0-2 years | Well-defined tasks with guidance |
| IC3-IC4 | Engineer II / Mid-level Engineer | 2-5 years | Features delivered independently |
| IC3-IC4 | Senior Engineer / Engineer III | 5-8 years | Projects and architecture for their team |
| IC5 | Staff Software Engineer | 8-12+ years | Multiple teams (typically 2-4), a domain’s direction |
| IC6 | Senior Staff Engineer | 12-15+ years | 10+ teams, or critical company-wide systems |
| IC7 | Principal Engineer | 15+ years | Company-wide technical leadership |
| IC8-IC9 | Distinguished Engineer / Fellow | 20+ years | The direction of the entire industry |
Junior to Senior (IC1 to IC4): team delivery
Each rung below Staff adds independence within a team.
Junior Engineer / Engineer I (IC1-IC2)
- 0-2 years of experience
- Works on well-defined tasks with guidance
- Learning fundamentals of software development
- Focused on individual contribution and growth
Engineer II / Mid-level Engineer (IC3-IC4)
- 2-5 years of experience
- Delivers features independently
- Requires minimal supervision
- Begins mentoring junior engineers
Senior Engineer / Engineer III (IC3-IC4)
- 5-8 years of experience
- Leads projects from design to delivery
- Mentors multiple engineers
- Makes architectural decisions for their team
- Trusted to handle critical systems
Below Staff, the focus is personal productivity and team delivery. The scope is a single team or project. Leadership happens by example, through code and small-scale mentorship. Decisions are tactical and project-level.
Staff Engineer (IC5): the first level of technical leadership
This is where Staff sits in the hierarchy:
- 8-12+ years of experience (varies widely)
- First level of “senior technical leadership”
- Influences multiple teams (typically 2-4 teams)
- Sets technical direction for a domain
- Individual contributor focused on high-impact work
Staff is a transition point. The focus moves to organizational impact and force multiplication. The scope grows to multiple teams, domains, or the entire company. Leadership comes through influence, architecture, and strategy. Decisions become strategic, with long-term consequences.
This is where a career moves from “great individual contributor” to “technical leader who multiplies the effectiveness of the entire organization.” The level reflects years of technical growth and leadership development.
Above Staff: Senior Staff, Principal and Distinguished
Three more rungs sit above Staff on the IC track.
Senior Staff Engineer (IC6)
- 12-15+ years of experience
- Influences a broader scope (10+ teams, or critical company-wide systems)
- Shapes technical strategy for an entire product area
- Recognized expert both internally and externally
- Not all companies have this level
Principal Engineer (IC7)
- 15+ years of experience
- Company-wide technical leadership
- Sets architectural direction for the organization
- Often has an industry-wide reputation
- Mentors Staff and Senior Staff engineers
- Represents the company externally (conferences, publications)
Distinguished Engineer / Fellow (IC8-IC9)
- 20+ years of experience
- Industry-recognized technical leader
- Influences direction of the entire industry
- Works on fundamental technical challenges
- Shapes the company’s long-term technical vision
- Extremely rare (most companies have 0-5 of these)
How Google, Meta and Amazon number the Staff level
The numbers differ by company. Here’s where Staff lands at three large companies and at a typical startup.
- L3 - Software Engineer II
- L4 - Software Engineer III
- L5 - Senior Software Engineer
- L6 - Staff Software Engineer ← Staff level
- L7 - Senior Staff Software Engineer
- L8 - Principal Engineer
- L9 - Distinguished Engineer
- L10 - Google Fellow
Meta (Facebook)
- E3 - Software Engineer
- E4 - Software Engineer
- E5 - Senior Software Engineer
- E6 - Staff Software Engineer ← Staff level
- E7 - Senior Staff Software Engineer
- E8 - Principal Engineer
- E9 - Distinguished Engineer
Amazon
- L4 - Software Development Engineer I
- L5 - Software Development Engineer II
- L6 - Senior Software Engineer
- L7 - Principal Engineer ← Staff equivalent
- L8 - Senior Principal Engineer
- L9 - Distinguished Engineer
- L10 - Amazon Fellow
Note: Amazon’s L7 “Principal” is often equivalent to Staff at other companies
Startups and small companies
Many smaller companies simplify:
- Junior Engineer
- Engineer
- Senior Engineer
- Staff Engineer ← Often the highest IC level
- Principal Engineer (if the company grows large enough)
Staff Engineer vs Engineering Manager: the parallel tracks
At the Staff level, the career ladder splits into two distinct paths.
| Individual contributor track | Management track |
|---|---|
| Staff Engineer (IC5) | Engineering Manager |
| Senior Staff Engineer (IC6) | Senior Engineering Manager |
| Principal Engineer (IC7) | Director of Engineering |
| Distinguished Engineer (IC8+) | VP of Engineering |
| CTO |
Staff Engineer is typically equivalent to an Engineering Manager, who manages 1-2 teams (6-15 people). It can also map to a Senior Engineering Manager, who manages multiple teams or managers. Staff Engineers lead technically, and managers lead people.
Both tracks are:
- Equally valuable to the organization
- Comparable in compensation
- Respected as leadership positions
- Capable of reaching executive levels
How companies decide your level
Scope and impact decide your level, more than years of experience. Companies assess four areas.
Scope of influence
- How many teams or systems do you affect?
- What’s the breadth of your technical decisions?
- How many engineers benefit from your work?
Technical complexity
- Are you solving problems others can’t?
- Do you design systems that will last for years?
- Can you navigate ambiguity and uncertainty?
Leadership and impact
- Do others seek your technical judgment?
- Do you multiply the effectiveness of teams?
- Do you raise the bar for engineering excellence?
Business impact
- Does your work measurably affect company goals?
- Can you connect technical decisions to business value?
- Do you enable the company to move faster or scale?
How long it takes to reach Staff
Most engineers take one of three paths. There’s no shame in a longer timeline, because quality of experience matters more than years.
Fast track: 6-8 years
- Started at a top tech company or fast-growing startup
- Consistently worked on high-impact projects
- Strong mentorship and clear career progression
- Possibly switched companies for growth opportunities
Typical path: 10-12 years
- Steady progression through levels
- Mix of different companies and roles
- Time spent building both depth and breadth
- Developed leadership skills alongside technical skills
Longer journey: 12-15+ years
- May have started in slower-moving industries
- Career breaks or career changes
- Focused deeply on expertise over breadth initially
- Equally valid path with different experiences
Where levels fall short
Not all Staff Engineers are equal, even at the same level:
- Some are early in the level (just promoted)
- Others are “senior” Staff (eligible for promotion but choose to stay)
- Impact and capability can vary significantly
- Company differences affect scope and expectations
The leveling system has limitations:
- It’s subjective, since promotion decisions involve human judgment
- It’s company-specific: Staff at a startup ≠ Staff at Google
- It’s political, sometimes rewarding visibility over impact
- It’s an imperfect proxy, since level doesn’t capture everything about capability
So don’t obsess over levels. The best engineers focus on solving interesting problems, growing their skills, making impact and building great products. The promotions follow when you consistently operate above your current level.
