Mosaic Conseil is a boutique remote workshop dedicated to rebuilding business artifacts one at a time. We do not produce slide decks or participate in corporate theater. Instead, we take existing pricing grids, three year plans, and diligence files, disassemble them on our bench, and reconstruct them based on the hard evidence of the invoice ledger. Our work is precise, intellectual, and backed by written arguments rather than visual fluff. We are currently focused on a significant engagement for our partner, a leading Spanish financial firm, helping them reorganize their internal project controls and financial artifacts.

About Mosaic Conseil
We operate as a small, focused team where every project is handled with a high degree of personal accountability. We maintain a deliberate size to ensure that the people doing the analysis are the same people answering the phone when a client has a question. Our firm avoids standing retainers, preferring to work on specific problems with clear endpoints. Every file we close carries two names:



a builder who constructed the model and a challenger who attempted to find its flaws. This rigorous process ensures that every assumption we make is tested against reality before it reaches the client. We focus our efforts on four specific sectors: financial services, industrial networks, growing software companies, and healthcare systems.

What you would do
In this entry level role, you will assist in the daily management of project artifacts and financial data. You will be responsible for maintaining the accuracy of the invoice ledgers and ensuring that every figure in a reconstructed model can be traced back to its source document. This involves a high volume of data verification and audit work. You will help organize the documentation for our engagement with the Spanish financial firm, ensuring that all project controls are updated and that deadlines are tracked with absolute precision. You will also participate in our internal challe
