This achievement should be a storyline mission, thus it should be unmissible.
To gain it, continue through the story until you get to Data_Miner, which will begin after you fight your first spider mech in the DeepStink during Empowerment. A cutscene will happen, and you will meet Kira. She will then require you to go to Cluster 13 and speak to her there. She will give you your objective which will send you to recruit a hacker you have gained the help of before. At this point, after you have spoken to Kira, she will upgrade your IMP, and the achievement should unlock.
