The salary definitely varies from field to field and whether you are an internal employee or an outside contractor/consultant. Another variable is geography. The coastal areas (California, Seattle, Boston, New York, etc.) tend to have higher cost of living than many central areas and therefore will tend to pay higher salaries.
For the life sciences industry of biotech/pharma in the San Francisco bay area, you may expect to make $80K - 120K based on your experience.
If you want to increase your salary, you need to prove your skills and get certified. Getting your PMP certification will definitely increase your salary base, likely by as much as 10%. Other certifications will help. Depending on your field, some common ones for the life sciences and manufacturing are certifications or training in Lean Six Sigma, CLIA, ISO, and GxP.
Lean and Six Sigma are methods for improving business processes and product compliance with standards.
Training and knowledge about:
Clinical Laboratory Improvement Amendments (CLIA),
International Organization of Standardization (ISO),
Good Manufacturing Practice (GMP),
Good Laboratory Practice (GLP), or
Good Clinical Practice (GCP) will definitely help you improve your skills and increase your salary for project management in the life science industries.
