The Maintenance Invoice Analyst is responsible for the final validation of all JSSI’s maintenance-related cost data entry. This role ensures that every line item transcribed from a maintenance invoice perfectly matches the original document. The Analyst is also responsible for enriching the cost data with contextual aircraft details, such as Part Numbers, Serial Numbers, Modules, and ATA Chapters. The contextualization may also include reasons for the cost, as well as relating to the JSSI HCM program coverage under which costs are incurred or attributed to in support of technical and financial analyses. The Analyst in this role is expected to assist with continuous improvements through pattern recognition, maintaining SOP, finding ways to improve accuracy, and identifying automation opportunities (through use of enterprise AI or software enhancements).
