What is a principal engineer?
A principal engineer is a senior engineer who supervises the engineering team, leads projects, and promotes innovation within the company. They work alongside project managers to ensure that all project requirements are fulfilled and that all project execution strategies are implemented for the smooth and efficient workings of the technical project.
Principal engineer skills
Principal engineers are highly technical engineers with years of experience in a specific engineering domain. Throughout their careers, principal engineers build specialized skills that help them leave their mark on the team. Here is a list we’ve curated of the skills required to be an effective principal engineer:
Analytical abilities
Team leadership
Project oversight
Communication skills
Expertise in a specific domain
Analytical abilities
As a principal engineer, your role is grounded in critical thinking and troubleshooting issues in the system with innovative solutions. You must adopt a proactive approach to not only address immediate challenges but also anticipate any potential concerns. This ensures the streamlining of development processes.
Team leadership
Principal engineers are at the top of the engineering hierarchy, with numerous teams under their supervision. From software engineers to electrical engineers, everyone seeks out the guidance and support of principal engineers to sort out issues with technical projects. At the same time, principal engineers also lead and inspire other engineers on the team.
Project oversight
Technical projects encompass numerous intricacies, complexities, and detailed processes that require the supervision of a technical expert. Principal engineers fulfill this role with their technical and engineering expertise, making sure that everyone knows their tasks and keeps everything on track.
Communication skills
The role demands effective collaboration between cross-functional engineering teams. The principal engineer communicates the OKRs and details of the projects to the team members and then conveys that information to the stakeholders. The principal engineer’s technical expertise helps them understand the engineers better in regard to different aspects of the project. In this manner, they first understand the projects in depth and then utilize their technical insights to suggest solutions.
Expertise in a specific domain
Principal engineers acquire their position after spending numerous years in a particular field. Most principal engineers have about 1015 years of experience within a specific domain, granting them significant expertise in it. This is helpful in times of unexpected challenges when principal engineers are typically already brainstorming creative solutions.
What does a principal engineer do?
A principal engineer is a versatile role with a diverse range of duties, including the following:
Research, develop, and design complex engineering projects
Think creatively and devise solutions for the company
Emphasize innovation to stay ahead of the competition
Develop and implement engineering strategies
Plan, create, and execute goals
Suggest product developments

Train engineers
Principal engineer vs senior engineer
Engineering leadership consists of five major levels:
Level 1: Software engineer
Level 2: Senior engineer
Level 3: Staff engineer
Level 4: Principal engineer
Level 5: Distinguished fellow
While both principal engineers and senior engineers have important roles in senior management, the two are at different levels, with distinct duties and scopes of responsibility.
Principal Engineer | Senior Engineer |
Provide direction to technical projects | Write code, review and maintain code quality |
High-level problem solving | Project-based problem solving |
Mentor teams of engineers | Mentor junior engineers within their teams |
Influence the technical culture of the company | Influence the internal decisions of their team |
Make long-term strategic decisions | Make decisions related to their team |
Understand multiple domains | Understand their specific domain |
Is principal higher than senior in engineering?
The specific responsibilities and ranking can vary by company, but generally, in many organizations, the title principal engineer is considered higher than senior engineer. Senior engineer is a mid to senior-level position that is responsible for handling complex engineering tasks independently and may begin to take on some mentoring responsibilities. On the other hand, a principal engineer is more senior than a senior engineer who possess a significant level of expertise in a particular area. A principal engineer is responsible for setting technical direction and ensuring the technical standards of projects.
Principal engineer career path
The career of a principal engineer is laden with years of experience in the field that provides significant technical expertise. There’s a general guide to becoming a principal engineer, which typically involves the following steps:
Get a bachelor’s degree in a CS or the engineering field
Master programming languages
Learn high-level technical skills
Polish communication skills
Gain experience in a tech-based company
Develop and maintain complex web systems
Develop exceptional leadership skills in a managerial position
Obtain in-depth knowledge of technical tools and software development methods
Principal engineer salary
Salaries for tech positions vary according to factors such as years of experience, expertise in the field, and the company's size. Generally, the salary of principal engineers is $180k - $220k per annum.
Final word
Principal engineers maintain a central role in engineering leadership. These engineers are handed the responsibility of guiding teams of engineers through the completion of projects, making sure that all of the team’s issues are promptly addressed and resolved. They maintain the utmost standards of work excellence while promoting innovation within the company.
