Hello Sanket,
Structural engineering is the field of engineering that deals with the design of building and other non-building structures such as the design of machinery, medical equipment, and vehicles, etc.
The major employers of structural engineer are :

• Engineering consultancies
• Local authorities
• Oil companies
• Railway operators
• Civil engineering contractors
• The civil service

Structural engineers have started salary lower but as soon as they develop skillet and gain experience, their salary rises. It varies from college to college.
I hope this is helpful.

• Good luck!
