E-discovery jobs focus on using technology to search data and records for electronically stored information (ESI), usually in response to a legal issue or an investigation. As part of this job, you may cull data using advanced search techniques, preserve data for later use, utilize write blocking software to prevent the destruction of forensic images, maintain a chain of custody, and otherwise ensure the integrity of ESI to ensure it is admissible in a court of law. Electronic discovery jobs are commonly available with law firms or on corporate cybersecurity teams. There may also be positions open with companies that deal with a lot of litigation and need to collect and preserve various types of information.
