It is a good practice to look at all of the responsibilities you have in any job. I would suggest making a master list to keep track of them all.
When it comes to creating a resume, it should be crafted to meet the requirements of a specific job posting. From your master list, see if there are any responsibilities that connect to what they are looking for in the position. If you have some and presumably you would if you were applying for the job in the first place, then list them on your resume.
If you haven’t already, create a Linkedin professional profile. Under the Experience section, you can list your current responsibilities in greater detail. Any potential employer will check out your Linkedin profile as part of their hiring process. If you have more, appropriate information listed there, it can likely give you some advantage.
You may need to give some thought to how you feature your responsibilities/duties. You need to quantify and qualify them.
Examples: Why are they important? Did you work independently? Did somebody closely oversee your work or were you fairly independent? Did you use any leadership skills in your current position? Are the skills you currently use in your position transferable to the new job?
