How much do senior principal research scientist jobs pay per year?
What are the key skills and qualifications needed to thrive as a Senior Principal Research Scientist, and why are they important?
How does a Senior Principal Research Scientist typically collaborate with cross-functional teams to drive research projects forward?
What is a Senior Principal Research Scientist?
What is the difference between Senior Principal Research Scientist vs Principal Research Scientist?
| Aspect | Senior Principal Research Scientist | Principal Research Scientist |
|---|---|---|
| Credentials | Advanced degrees (PhD), extensive research experience, often with publications | Similar educational background, strong research record, and industry expertise |
| Work Environment | Leading research projects, mentoring teams, strategic planning | Conducting independent research, collaborating across teams, publishing findings |
| Employer & Industry Usage | Used in large tech, pharma, and R&D organizations for senior research roles | Common in similar industries, often a step below Senior Principal |
The main difference lies in the seniority and scope of responsibilities. Senior Principal Research Scientists typically lead larger projects, mentor junior staff, and influence strategic decisions, whereas Principal Research Scientists focus more on independent research and technical contributions. Both roles require advanced credentials and industry experience, but the Senior Principal position emphasizes leadership and strategic impact.

Job description
Northrop Grumman Aeronautics Systems has an opening for a Principal/Sr. Principal Research Engineer Level 3/4 to join our team of qualified, diverse individuals. This position will be in Clearfield, UT. Our Research team works to support process development and automation of composite aerospace structures. We engineer the latest composite structures for military/commercial aircraft and launch structures and are leaders in next-generation composite development. We operate as principal investigators over Internal Research and Development (IRAD), Process Service (PS), and Customer Research and Development (CRAD) projects and production support, with responsible technical development as well as management of schedules and budgets. Would you like to work on the cutting edge of aerospace? Come join our team!
This specific role will require the capacity for high level understanding of composite materials including advanced resin systems, fiber reinforcements, prepregs, film adhesives, surface science, bond preparation, part bagging, autoclave/oven curing and general material science. Expected to work collaboratively with a research and development team across the site and sector for new composite manufacturing related innovations and troubleshooting of current processes. High competence with diagnostic and analytical techniques such as FTIR, DSC, TGA, DMA, rheology and SEM is also very desirable.
We work 9/80 work week, which gives us every other Friday off to pursue passions outside the office. Travel varies with each project, but typically for a Principal/Sr. Principal Engineer will travel 10%, and primarily within the continental US. We work with our team to try and allocate travel responsibilities to those who are able and enjoy travel. Northrop Grumman offers a full suite of benefits to our employees.
Responsibilities:
- Develop processes and optimize material solutions for pilot scale fabrication of complex composite materials. Plan and execute the transition to production scale manufacturing and assist in defining equipment and floor plan needs.
- Develop new material systems that are amenable to additive manufacturing, fiber placement and other automated composite fabrication techniques.
- Solve technical issues using root cause methodologies based on underlying scientific principals and an understanding of chemical processes
- Identify and develop technical solutions that meet IRAD and Process Service project goals
- Provide technical decisions and recommendations based on data and project outcomes
- Lead development efforts to reduce cost, increase process efficiency, and ensure consistent quality in support of current and future programs
- Work with internal and external partners to champion and ensure success of R&D projects
- Act as principal investigator on selected new proposals and projects
- Manage execution of the project requirements to cost and schedule objectives
- Foster an environment of cooperation and teamwork within the Process and Technology Development team
This role may be filled at a Principal/Sr. Principal Research Engineer level 3/4 depending on the qualifications below.
Basic Qualifications:
Principal Research Engineer Level 3:
- Bachelor's Degree in STEM field (Science, Technology, Engineering or Mathematics) and 4 years of engineering experience or Masters in a STEM field and 3 years of engineering experience; OR PhD in STEM with 0 years of experience.
- Material and Process Engineering experience in composite material
- Must have the ability to obtain and maintain a U.S. Government Clearance
- Must have the ability to obtain and maintain Special Program Access (PAR)
