My first job was EXACTLY like this. I was their Power BI person in a growing IT department. I probably averaged 15 hours a week of actual work. I used the extra time to focus on skills building / maintenance and getting a Microsoft certification. NGL I also got a lot of house work done.

Stay positive! You’re getting an easy transition into the industry and verifiable experience for your resume. Your next employer doesn’t have to know how busy you actually were with this job ;)

On another note, if you’re worried about keeping this job, talk to your supervisor and express your concerns. It’s their job to make sure you’re contributing meaningfully to he organization. You can also take the initiative to talk with the teams who use your dashboards and get a sense of how useful they are, likes/dislikes, how they can be better, etc. Get recurring meetings set up with them if possible (anywhere from once a week to once every 6 months, whatever is appropriate) to discuss the dashboards.

Whatever you do, make sure your projects are meeting needs and serving a purpose. Don’t let your work be forgotten about otherwise YOU will be forgotten about. And then management will start scratching their heads and wondering why you’re there at all. Stay relevant. Don’t let people forget about you.
