Principal Architect vs. Senior Architect: What Are the Differences?

Learn about the two careers and review some of the similarities and differences between them.

Architects design and oversee the construction of buildings and other structures. There are many different types of architects, each with their own area of expertise. Two common positions are that of a principal architect and a senior architect. In this article, we compare and contrast these two positions, discussing the similarities and differences between them. We also provide information on what you can expect in terms of salary and job outlook.

What is a Principal Architect?

Principal Architects are the creative leaders of an architectural firm. They develop the overall design concepts for a project and see it through from the initial planning stages to completion. Principal Architects usually have a team of junior architects and support staff working under them. They delegate tasks to the team and provide guidance when needed. Principal Architects are responsible for ensuring that the project meets all the necessary requirements, such as building codes and safety regulations. They also need to make sure that the project stays within the budget and is completed on time.

What is a Senior Architect?

Senior Architects are responsible for leading a team of architects and engineers to complete the design and construction of buildings and other structures. They work with clients to determine the scope of the project and the budget, then they develop a plan and timeline for the project. Senior Architects oversee the entire design process from start to finish, making sure that the project stays on track and meets all the necessary requirements. They also review construction documents and blueprints to make sure they are accurate and up to date. Senior Architects typically have many years of experience in the field and may hold a professional license.

Principal Architect vs. Senior Architect

Here are the main differences between a principal architect and a senior architect.

Job Duties

One of the clearest differences between a principal and senior architect is the set of duties each professional holds. A principal architect oversees an entire firm or department, which can include hiring new employees, creating new policies and overseeing projects. They also often work on large-scale projects that require significant planning and budgeting.

In contrast, senior architects typically handle day-to-day operations within their departments and teams. They may oversee design projects from start to finish and provide feedback to junior members of the team. Additionally, senior architects may mentor other employees by providing technical guidance and offering advice.

Job Requirements

Principal architects typically need to have a bachelor’s degree in architecture, although some may have a master’s degree as well. They must also be licensed by the state in which they plan to practice. To become licensed, architects must pass an exam administered by the National Council of Architectural Registration Boards (NCARB). Some states also require architects to complete continuing education credits to maintain their licenses.

Senior architects usually need to have at least five years of experience working in the field before they can be considered for a senior-level position. In addition to experience, senior architects often need to have a master’s degree in architecture or a related field. They must also be licensed by the state in which they plan to practice.

Work Environment

Both principal and senior architects work in an office environment. They may travel to construction sites, however, to oversee the progress of projects. Senior architects often have more responsibilities than principal architects, so they may spend more time on-site or traveling between locations.

Principal architects usually work full time for a company, while senior architects typically work part time. This allows them to take on fewer projects and focus on their personal interests outside of work.


Both principal architects and senior architects use similar skills in their jobs, such as problem-solving, creativity and technical knowledge. They both also need to be able to communicate effectively, whether they are presenting their ideas to a client or team or writing reports.

However, there are some differences in the skills that these professionals use. For example, a principal architect may need to have more business skills than a senior architect. This is because they may be responsible for running their own architecture firm or department within a company. They may need to market their services, manage finances and oversee other staff members. A senior architect may not need to have as much business acumen as they typically report to a principal architect or another manager.

Another difference between these two roles is that a principal architect may need to have more teaching and mentoring skills than a senior architect. This is because they may be responsible for training and supervising junior architects and other staff members. A senior architect may still provide guidance to others, but they typically do not have the same level of responsibility for teaching and mentoring.


The average salary for a principal architect is $153,763 per year, while the average salary for a senior architect is $120,615 per year. The average salary for both positions may vary depending on the size of the company at which you work, location of your job and the level of experience you have prior to pursuing either position.
