Both examples are easy and non-formal ways of saying you are new at your job or just changed jobs. You don't really need to go further than these sentences because if you just changed jobs or started a new job it is implied that it is recent.
When you want to explain that you have started a new job, then you can explain in the following ways:
-When you're working for the same company but have a new job position (and description), then you can say:
a) I recently changed posts. I got a promotion (to manager from assistant manager)
b) I just recently started my new job (post) with my company.
-When you're working for an entirely different company; then you can say:
a)I got a new job recently. (I stopped working for my old company)
b) I just recently started a new job. I'm excited about moving to a different company and environment.
新しい仕事を始めたと伝えるときに使える表現です：
-同じ会社で働いていて、ポジション（社内のポジション）が変わった時は：
a) I recently changed posts. I got a promotion (to manager from assistant manager)
最近ポジションが変わったんだ。（アシスタントマネージャーからマネージャーに）昇進したんだ。
b) I just recently started my new job (post) with my company.
会社で最近新しい仕事を始めたんだ。
-全く違う会社で働き始めた時は：
a)I got a new job recently. (I stopped working for my old company)
最近転職したんだ。（前の会社を辞めた）
b) I just recently started a new job. I'm excited about moving to a different company and environment.
最近転職したんだ。会社と、環境も変わるから楽しみ。
