E3 – Software Engineer II:

• Responsibilities: Engineers at this level are typically recent graduates or individuals with limited professional experience. They focus on completing individual tasks with guidance, delivering quality code, and responding constructively to feedback. They often require assistance to unblock issues and rely on mentorship from more experienced engineers.
• Autonomy: Limited; they often require assistance to unblock issues and rely on mentorship from more experienced engineers.

E4 – Software Engineer III:

• Responsibilities: E4 engineers work on projects delivering complete features, own technical specifications, and collaborate across teams to ensure successful delivery. They operate mostly independently and assist colleagues through code reviews and constructive feedback on technical decisions.
• Autonomy: High; they are expected to manage their tasks with minimal supervision and contribute to team objectives proactively.

E5 – Senior Software Engineer:

• Responsibilities: At this level, engineers own problem spaces or projects end-to-end, create scopes for themselves and others, drive technical alignment across functions, and mentor junior engineers. They set and maintain quality standards for the team and can deliver results through others.
• Autonomy: Very high; they are expected to lead initiatives, influence technical direction, and have a significant impact on team and company goals.

E6 – Staff Software Engineer:

• Responsibilities: E6 engineers play a critical role in setting the direction and goals of the team. They are involved in roadmapping, scoping work, and managing technical problems that span outside of the team, influencing the organization. They handle the most challenging problems, can cover for missing Product Managers or Engineering Managers if needed, and advocate for high quality and engineering excellence.
